Due to ever tightening federal EPA requirements, today’s motor oils have
reduced quantities of anti-wear chemistries like Zinc, Phosphorus and Sulfur. As a result, the oil you buy today is not the same as it was 10 years
ago. While this is good for most stock daily driven street cars, it is bad
news for your racing engine. Racing engines see more RPM, higher loads
and increased temperatures compared to street engines, so a racing engine requires higher levels of these wear additives to prevent premature
part failure. So you see, the oil used in an engine needs to be formulated
specifically for that type of engine. You wouldn’t use a stock piston in a race
engine, and the same goes for oil. And that’s where Driven excels.

Our products are unique because we always put the “motor ahead of the
molecule.” Often, oil companies have no real world understanding of how
these products are actually used, but Driven keeps things in the proper
order. The oil is for the motor, not the other way around. Our product
development team looks at the motor and how it is used; then we design
application specific products using a “zero compromises” approach that
delivers a measurable performance advantage.

Driven Is
Different
If you think all oil performs
and protects the same then
you would be mistaken.
Driven Racing Oil’s Lubrication
Specialist Lake Speed, Jr. tells us just
how different Driven Racing Oil is.
A
ccording to Speed, “the last thing the world needs
is another oil company” and “there’s no such thing
as the best oil.” Strange words coming from a man
who has devoted his entire career to just that – oil. But
this devotion also makes him understand that “best oil”
isn’t actually the principle – it’s the “right oil.”
Driven Racing Oil was originally created to advance
engine and driveline lubricant performance in all-out
race and high performance engines, but now those
innovations extend beyond the racetrack to the street.
The product line is unique in that it “puts the motor
ahead of the molecule.”
Often oil companies have no real world understanding
of how these products are actually used, but Driven
keeps things in the proper order. The oil is for
the motor, not the other way around. The product
development team looks at the motor and how it is
used; then they design application specific products
using a “zero compromise” approach that delivers a
measurable performance advantage.
Lake Speed, Jr. Explains Why “Driven Is Different.”
Does racing R&D transfer to the average Joe on the street?
What we learn in racing we do apply across the board – we the take basic chemistry from the toughest race
environment and apply it to street performance.
You’re a small company – how are you able to compete with the big name companies?
The small company size allows us to be nimble and deal directly with the end user. When you call Driven, you talk
to the head tech guy, not a mid-level customer service person who didn’t actually formulate the product. And our
products are used at the highest levels of motorsports all the way back to the guy in his garage.
What does the future hold for Driven?
We stay in constant communication with the end user to stay on top of an ever evolving market. So, armed with
that information, we’ll then use chemical engineering to enable higher performance, better fuel economy and
lower emissions across the spectrum of vehicles. This will also help us develop more advanced technology to
bring to the table. Performance enthusiasts will always push the envelope – we’ll help push them to that next step.

We went to the
valve train experts
at COMP Cams to
get the scoop on
their line of LS
performance lifters.
3

1
Link Bar Hydraulic Roller Lifters
(Patent Pending)
This COMP Cams hydraulic roller lifter with a link bar design
does away with the factory lifter trays and features a patent
pending piston allows trapped air to escape the lifter for faster
“pump up.” Axles produced from premium 52100 heat-treated
steel make for increased wear resistance and overall strength
while still maintaining an overall lightweight body design.
Starting at $551.86.
Link Bar Short Travel
Hydraulic Roller Lifters (Patent Pending)
These hydraulic roller lifters from COMP Cams let you have the
advantages of both a light pre-load that allows quick recovery
from bad harmonics in the valve train and heavier pre-load that
reduces oil volume under the plunger and increases stiffness.
These are the most stable and highest revving hydraulic lifter
available for LS engines. Starting at $564.17.
Endure-X
Solid Roller Lifters
With today’s more aggressive cam lobe designs and
increased RPM ranges, it takes a superior roller lifter to withstand the abuse. COMP Cams addressed
this issue with the Endure-X Lifters that are fully
heat-treated, machined to ultra-high tolerances and
are fully rebuildable. The four main features of
these lifters include: a removable link bar, EDM Oil
Injection Technology, precision sorted needle bearings and a tool steel axle. Starting at $606.91.
Removable Link Bar Combines the benefits of a removable link bar with the safety of a captured link bar.
EDM Oil Injection Technology Guarantees the bearing assembly receives a constant flow of pressurized oil via
a precision hole aimed directly at the needle bearings.
Precision Sorted Bearings Precision-sorted by size
to distribute load evenly, preventing premature
wear and failure.
Tool Steel Axle Made of wear resistant Tool Steel to
prolong life of the roller assembly.

Rocker ArmS
O
ne of the most important components in your
engine is the rocker arm. It is also one of the
most vulnerable. As the turning point of the
valve train, the rocker arm is basically a sophisticated
lever that redirects the upward tappet and pushrod
movement and then multiplies it by the rocker ratio to
downward movement at the valve.
Aluminum Rockers
Until recently, aluminum rocker arms have been considered a
more affordable but less durable option to steel rockers. COMP
Cams has developed aluminum rockers that use precision-sorted needle bearing trunnions to withstand both aggressive spring
pressures and valve lift. The COMP Cams Ultra-Gold ARC Aluminum Roller Rockers actually have the highest rocker-to-valve
spring clearance of any aluminum rocker – up to 1.625" valve
spring O.D. And while these aluminum rockers are lightweight,
they are still incredibly strong and feature a lifetime warranty.
Make the rocker arm stiffer To increase stiffness,
look at three characteristics: material, geometry and the
rocker’s holding fixture. The easiest way to increase stiffness
is to switch to chromemoly steel. Although heavier than some
other materials, it can offer some design advantages and
have much thinner sections than aluminum due to its superior
strength density. Stiffness of the mounting is just as important
as the stiffness of the rocker body. For the ultimate in high performance, shaft mounted rockers may be the way to go.
Steel Rockers
COMP Cams steel rocker arms are all constructed from 8620 or
8650 chromemoly steel, which is a higher grade material that
makes them extremely durable and tough. The material keeps
them from flexing, and they have large trunnions and more needle bearings, which allow the load to be more evenly spread
and the rocker to last longer. Steel can thus be run in harsh environments without fatigue issues. Some COMP steel rockers are
even lighter than most aluminum because COMP has reduced
mass in low stress areas.
Decrease the moment of inertia The moment of inertia
is the rocker’s resistance to rotation. The higher this measurement, the more valve spring pressure it takes to control the
rocker arm instead of the valves – losing RPM and horsepower.
The moment of inertia is lowered by lightening the rocker arm’s
weight, particularly at areas that are farther from the trunnion.
Two ways you can do this are by switching to a lighter weight
material or by removing mass from the rocker body design.
stud/Shaft mounted
Three Basic Ways To Increase Power
Through A Rocker Arm Change
This is a highly critical process. Due to stresses and
vibrations, which are more prevalent during high speed
operation, rocker arms undergo what is known as deflection. Severe rocker arm deflection causes inefficient
engine performance, and often results in metal fatigue
leading to increased wear and friction in the valve train
and eventually engine failure.

2
Lift the valve more By increasing the rocker arm ratio, it’s
possible to increase valve lift without ever touching the camshaft. Valve lift can typically be increased as much as 10% by
increasing rocker ratio.
3
Stud mounted rockers have evolved over the years, resulting

Shaft Mount
Aluminum Rocker Systems
Shaft mount rocker systems transfer the power of
the camshaft to the valve by properly positioning
the rocker over the valve. According to COMP Cams
the rigidity of the shaft system adds stability to the
cylinder head and valve train, and the oiling system
ensures consistent oil flow from the pushrod cup
to the shaft bearings and then on to the roller tip.
Constructed from 2024 aluminum and uses an 8620
hardened steel shaft. Starting at $1,183.98.

Universal
Engine Swap?
GM’s LS-based engines are the most popular engine swaps today
with muscle car and hot rod car builders. So what makes them so popular?
W
hen the first LS engine
appeared in the 1997 Corvette, it left traditional
Chevy engine fans scratching their
heads. Here was an engine that rewrote all of the rules with virtually
nothing that interchanged into the
classic Small Block Chevy launched
way back in 1955. Some doubted its
staying power. But engine builders
took a wait-and-see mentality to
determine if the aftermarket would
embrace this new engine.
As we all know now, the LS family
of engines has grown dramatically.
Its versatility to make power and
torque with new and uniquely LSbased components has changed the
way racers and enthusiasts race and
drive their vehicles. Today it has become the preferred “resto-mod” engine for a number of reasons.
Top reasons to go LS
Great durability: The LS engine has
better sealing characteristics than either the classic Chevy small or big

Key Design Features Common to all LS Engines

block engines. This includes not only
the oiling systems, which were tragically flawed with the classics, but
with head gaskets which have better
cylinder and water jacket sealing.
Easily adaptable: As the engine has
evolved, both the factory and the aftermarket have created new ways to
make power. Whether you are using
the steel block truck LS base (which
is highly available, sturdy and inexpensive) all the way to the LS9, you
can swap from a wide range of heads
and cranks along with naturally aspirated intakes, superchargers or turbo
systems. The number of aftermarket
components available from intake

engines is 4.40"
6. Lifter bores measure 0.842"

manifolds to off-the-shelf and custom
ground camshafts make just about
any performance target reachable.
Easy power: While the newest LS9
engine makes up to 638 horsepower and tons of torque, aftermarket
changes can net far more power. This
slim dimensioned engine (have you
measured the Ford Coyote engine
valve cover width?) will fit in a wide
variety of engine bays. But the key
is the ease with which power adder
parts can be bolted in place. Just take
a surf for online products through
the Summit (www.summitracing.
com) or Jegs (www.jegs.com) websites for some happy results.

Emissions compatible: GM started early
in the game of building engine “packages,” making it easy for enthusiasts not
wishing to battle emissions regulations.
LS engine buyers will find it easy to build
up an engine that features excellent drivability through modern car-style fuel injection and full emissions legality.
Engine Swap Kits
There are a wide variety of engine swap
kits available that allow easy installation
of your LS engine into many classic domestic and assorted import vehicles.
They offer hard-to-find parts, such as oil
pans, that are compatible with the OEM
tie rods and K-members, remote air intake systems that sidestep the need for
modifying stock hoods and complete
electronic fuel injection wiring retro-fits
to replace classic carbureted engines with
modern fuel injection. Your best guide
here are LS forums such as LS1Tech.com.
The possibilities will amaze you.

Bitchin’
Camaro
LS power & modern day suspension make this classic muscle car 100% cool
Photos by Norm Brandes & Joe Lewandowski
Carl Schultz had a ’69 Camaro.
It was a clean, very straight, old restoration with classic drivetrain but in
need of new power and suspension.
With dreams of a more modern and
efficient muscle car, Carl met with
Norm Brandes and Jim Daley from
Silver Lake, Wisconsin’s Westech Automotive at the 2012 Performance
Racing Industry show in Orlando.
Shortly thereafter, a complete Camaro ready for performance upgrades
showed up at the Westech Shop.
After serious discussions among all
involved about potential forms of
LS engine transplants, Carl, owner
of Five Star Racing Bodies, settled
on a new GM Performance LSX454
engine cranking out over 620 horsepower. Adding to that total, Westech
Automotive added a FAST LSXR Intake with a Big Mouth Throttle Body
to build upon the impressive power.
This Camaro fools the competition by packing
a 620 HP LSX454 engine under the hood.
20
LS Performance
While original plans called for a 200R4
automatic transmission to replace the
apparent factory 350TH currently in
the car, a total redirection was ultimately made, inserting a Tremec TKO
six-speed after it was determined that
the original fitment was for a 4-speed
manual transmission. To ensure pos-
itive tire engagement, a heavy-duty
clutch plus a strong and lightweight
driveshaft were installed to control
the massive horsepower and torque.
To improve the drivability of the car,
Westech engineered a throttle-by-cable fuel injection system over the more
common throttle-by-wire controls
typically found with this engine. The
spark plug coil packs were mounted
by the oil pan to keep all wiring out of
view and the plumbing was contained
with stainless steel tubing, making for
a super clean engine compartment.
But it was clear to both Norm and
Jim at Westech, along with Carl, that
the car had to stop and handle as
well as a new Camaro. Happy with
the modifications made to modernize
the power and throttle response, they
turned to the suspension.
To get the right handling and chassis
strength, they called on Heidts Hot
Rods and Muscle Cars of Lake Zurich,
Illinois, to achieve those key features.
In the rear they installed a Heidts
four-link suspension — two inches
narrower than stock — to accommo-

date the increased width wheels and
tires they had planned.
Up front, they used the Heidts Pro-G
subframe featuring rack-and-pinion
steering for crisp cornering and excellent steering response. Massive diameter Wilwood disc brake rotors accompanied with six-piston front and
four-piston rear calipers netted better
than a modern car stopping power.
Finishing off the Camaro, Norm and
Jim attended to some of the spots on
the paint needing touch-up but for the
most part left the exterior as it arrived.
To that they added SS-style graphics
and the original 350 c.i. engine emblems to fool the competition as to
the amazing power under the hood.
The result is a car that checks all the
boxes with regards to modern Camaro
performance while wrapped in one of
the best Camaro shapes ever to leave a
GM assembly line.
Ask Carl about his ’69 Camaro now.

Conical Valve Springs
Expected to become the new standard in
high performance valve spring design,
COMP Cams Conical Valve Springs utilize
a round wire and feature a diameter and
progressive pitch driven natural frequency. The conical shape constantly decreases diameter from the bottom to top to
reduce active mass and decrease applied
forces, which results in longer valve train
component life and less parasitic horsepower loss. This design also increases the
valve train RPM limit while reducing resonance concerns and decreasing dynamic spring oscillations. It dampens without
wear, heat/friction or risk from interference contact. The result is longer spring
life and the ability to run more aggressive
camshafts. Superfinish surface processing also increases both lift capability and
spring longevity.

Cam Phaser Limiter Kits (Patent 8,291,876 B2)
Cam phasers are computer-controlled cam gears that automatically optimize cam timing based on current engine
RPM and are used in 2007+ GM Gen IV VVT (Variable
Valve Timing) engines. Engine oil is pressure-fed to the
phasers through passageways in the cylinder heads and
cams. The engine computers control solenoids that adjust
this oil flow throughout the phasers’ control chambers, creating the ability to retard the cams.
wide range of valve timing movement, there is very little
piston-to-valve clearance, which limits you to small cam
profiles with little overlap. COMP Cams Cam Phaser
Limiter Kits restrict the range of cam timing movement
to 22°, thereby providing the necessary valve clearance
for serious performance cams with tighter lobe separations – all while utilizing the benefits of VVT technology. Starting at $64.22.
While this technology provides fuel efficiency and the
ability to always be in the best position for maximum
power, regardless of engine RPM, it presents some limits when it comes to performance cams. With such a

RED HOT
A 2013 Camaro 1LE With Mods
To Make Sure It Lights Up
The Competition
Story & Photos By
ChevyHardcore.com
In 2013, Chevrolet released the 1LE package for Camaros.
This package was an upgrade from the SS package that
offered an affordable alternative with many of the ZL1’s
upgrades, but didn’t have the supercharger bolted to the
motor. Many aspects made the transition though, such as
the blacked out hood, upgraded suspension and suede
appointed interior.
Our shop can get extremely backed up with project cars,
so having a local shop that specializes in late-model GMs
is a valuable asset. When it comes to GM cars, our partner
to help with the work load is Cunningham Motorsports, in
Murrieta, CA. CMS specializes in tuning and tweaking GM
cars. One day when we were at CMS, we noticed a brand
new, shiny red Camaro SS 1LE sitting out front and had to
know what the story was behind the car.
Ryne Cunningham the owner of Cunningham Motorsports, said the Camaro was his personal ride. We chatted
with him about the car, but not much else was said about
it. However, over the course of a year we noticed that
the Camaro was receiving upgrades. CMS had to put their
touches on the car to make sure that the Camaro reached
its full potential.
Acquiring The 1LE
We asked Ryne what caught his eye about the 1LE Camaro,
besides the bright red paint. “For me it was the price point.
I was able to get an SS Camaro, with a ton of upgrades for
a great price.” His plans were to take the car to the occasional road race, but mainly drive it daily. The plan was
never to leave the Camaro in stock form though.
27
Starting Modifications
Showing what CMS was capable of, they started by installing a
set of American Racing headers to help free up some horsepower. These headers are 100% American made from stainless steel.
According to their website, just bolting on these headers will
provide an extra 32 WHP, without a tune.
From there he ordered up one of his own custom ground COMP
Cams. These cams are specifically ground to CMS specifications.
With this cam, the motor has a nice lope to it but is still street
able and tame. Being a proprietary CMS product, Ryne wouldn’t
give us the exact specs. After the new bump stick was installed,
a cold air Airaid intake was installed.
After all these modifications were complete, the car was thrown
on the dyno to see what it could do. What Ryne walked away with
was an impressive 432 lb. ft. of torque and 472 HP, at the wheels.
Suspension Upgrades
Turning his attention from the engine, Ryne looked at the suspension. Even though this car had the upgraded 1LE suspension, he knew there was more potential in the Camaro to make
the car handle flawlessly on the track. What he did was replace
the stock sway bars for a set of high performance Pfadt sway
bars in the front and rear to keep the car planted.
While he was tinkering with the suspension, a set of Pfadt drop
springs were thrown in to get the stance on the car just right
and lower the center of gravity. In the rear, a set of Pfadt cradle
bushings were added as well, to keep the rear end in the right
spot and prevent any driveline vibrations.
Now that the car had the right stance, a new set of wheels
was in order to finish off the menacing look of the car. Cunningham called Forgeline to get a set of wheels for the car.
In the front he opted for a set of 20×10.5" GA3’s and a set of
20×11.5" for the rear. The GA3 wheels are worth noting as
well as these aren’t just a fancy set of wheels. Forgeline used
all of their racing knowledge to produce this street version of
their race GA3R wheel. They are made from 6061-T3 aluminum with heat-treated rim shells and assembled with stainless
steel hardware. The “I-Beam” technology reduces weight in
the wheel but provides extra strength.
With custom finishes available from Forgeline, Cunningham
picked a gloss black hoop with contrasting flat black spokes for
a dramatic look. They are wrapped in a sticky set of BF Goodwrich Rivals, 285/35/R20 in the front and 315/30/R20 in the
rear to keep the car stuck to the ground like glue.

This car not only catches the eye, but
backs it up with 472 HP under the hood.

Testing The Limits
Once all the mods had been done, Ryne wanted to
really test the car out. “I took the car on a half mile
airport strip and did 147 mph, hitting the rev limiter.”
That just tells us the car has more in it for a higher
speed, but the car wasn’t built for that. “I also took the
car to Big Willow Springs, where I ran the course in
1:34.4,” he added. Big Willow, in Rosamond, CA, is a
2.5 mile road course located two and a half hours north
of Cunningham Motorsports. Looking at the Big Willow
track records, we see Mario Andretti holds the record at
1:06.050 seconds in an Indy Car. Cunningham’s record
is pretty impressive for a car three times the size and
weight of the track record holder.
Selling The 1LE
As is the case with many gearheads, when the car was
“finished” Ryne got bored with it with only 7,200 miles
on the odometer. He decided to sell off the car to help
finance the next project. We asked him what happened
to his red hot ride and he pointed to his right-hand man
in the shop, Mike Franz. When Ryne decided that he was
ready for that next project, he started asking around if
anybody was interested in the 1LE. Mike raised his hand
saying he would love to buy the car. A deal was struck
and the car now resides with Mike.
New Ownership
Mike is a Chevy man through and through. This 1LE Camaro is actually the fifth Camaro he has owned. “I grew
up in a Chevy family, so I was raised around Chevys” he
explained. After test driving a Dodge Challenger and Ford
Mustang, Mike knew the Camaro was the car he wanted.
“For me these 5th Gen Camaros were the fastest, most
comfortable, with a back seat and in my price range.”
We asked Mike what he really loved about the car. “I’m
the bully at the stoplight” he said laughing. “I have a car
that catches eyes but has the power to back it up.”
Even though he’s not a big fan of red cars, something just
drew Mike to this particular Camaro. “I was just drawn to
the red on this car, plus I’m the one that turned all the
wrenches on this Camaro at CMS, so I knew it well.” Since
all the upgrades had been done with the car, Mike said
he hasn’t really made any major modifications to the car
since it’s been in his possession.
The few modifications that Mike did to help make the car
his own was to add a pair of ten-inch Rockford Fosgate subwoofers in the trunk for a little bass. Since he also worked at
CMS, he couldn’t just leave the car alone. He figured out how
to control the two stage mufflers with a remote control. Now
he can push a button and go from stealth mode to race mode
and back again. A neat little trick to have in your pocket, especially if the police are sitting behind you at a light.
Future Plans
We noticed that Mike really babies this car when cruising
around. Being big gearheads we would want to constantly
mash the throttle. “This car is my daily driver that I rely
on to get to work and back, so I try to not beat it up too
much,” he said. He does have plans to take it down the
drag strip to see what the car can do though. “I don’t really
want to take it on a road course because that beats up cars
pretty good, and I still have to make it to work on Monday.”
When talking about the car, Mike has nothing but a huge
smile on his face. He said that he drives the car everywhere,
in any weather. There’s nothing wrong with daily driving a
super car, except trying to keep your foot off the gas.

How To Choose Your
Precision-Flow Fuel Injectors
1.Take your target peak horsepower and multiply by
••.5 for naturally aspirated
••.6 for supercharged
••.625 for turbocharged
2.Take that figure and divide by the number of cylinders.
3.Divide by .9 (for 90% duty cycle).
This will give you the lb./hr. you will need from each injector.
Example: 520 horsepower, naturally aspirated V8
(520 x .5=260), (260/8=32.5), (32.5/.9=36)
This application would require 36 lb./hr. Precision-Flow Fuel Injectors (Part #303600).
If the formula gives you a number that is not one of the injector sizes, the general rule is
to move up to the next largest size.

Torque
Converters, INC.
Performance enthusiasts often underestimate the
critical role torque converters play in putting their
expensive horsepower to the pavement.
TCI converters are designed by experienced
drivetrain engineers to provide a significant
increase in performance on the street or at
the strip. With a more efficient stall speed,
faster acceleration and better mid-range
power, your machine will get the rear wheel
power it deserves.
Some special features of TCI torque converters include furnace-brazed fins for reinforcement and durability as well as heat-treated
sprag races for increased strength and life

span. They also utilize bearings that increase
thrust capacity and reduce drag, as well
as turbine spline reinforcement welds for
increased durability and a heat-treated steel
hub that increases converter strength.
TCI employs a highly specialized production process that ensures each unit is built
to spec. Regardless of the category or price
level in which a TCI torque converters falls,
rest assured that it has been Triple Tested
during assembly.
Torque Converters Explained
Impeller Pump The impeller pump is the outside half of the converter on the transmission side of the weld line. Inside the impeller pump is a series of longitudinal fins that drive
the fluid around the outside diameter into the turbine because this component is welded
to the cover, which is bolted to the flexplate. The size of the torque converter (and pump)
and the number and shape of the fins all affect the characteristics of the converter. If long
torque converter life is an objective, it is extremely important that the fins of the impeller
pump are adequately reinforced against fatigue and the outside housing does not distort
under stress.
Stator The stator can be described as the “brain” of the torque converter, although it is not
the sole determiner of converter function and characteristics. The stator, which changes fluid
flow between the turbine and pump, is what makes a torque converter a converter (multiplier) and not strictly a fluid coupler. With the stator removed a converter will retain none of its
torque multiplying effect.
Turbine The turbine rides within the cover and is attached to the drivetrain via a spline fit
to the input shaft of the transmission. When the turbine moves, the car moves.
Cover The cover (also referred to as the front) is the outside half of the housing that
faces toward the engine side from the weld line. The cover serves to attach the converter
to the flexplate (engine) and contains the fluid. While the cover is not actively involved in
the characteristics of performance, it is important that the cover remain rigid under stress
(torsional and thrust stress as well as the tremendous hydraulic pressure generated by the
torque converter internally).
TCI employs a highly specialized
production process that involves
ensuring that each unit is built to
spec. Regardless of the category
or price level in which a TCI torque
converters falls, you can rest
assured that it has been Triple
Tested during assembly.
Once all prep work on the component parts has been completed,
the impeller is welded to the front
cover. Immediately following this
process, a pair of dial indicators
is employed on a rotating table
to verify that the impeller body
and pump drive hub remain true.
Each unit is then pressurized and
subjected to a leak test to confirm
the integrity of all weld seams.
Last, each unit is computer
balanced to reduce annoying and
potentially damaging drivetrain
vibrations that can occur from
an unbalanced torque converter.
That's triple tested so you can be
confident you are receiving the
perfect torque converter for your
specific application.

Frequently Asked Questions
About TCI Torque Converters
With an automatic transmission, a torque converter is chosen
by its stall speed. Select a torque converter with a stall speed
300 to 400 RPM higher than the peak torque output of your
engine if you are using a transbrake. Below are some other
frequently asked questions about torque converter stall.
What is stall speed?
Stall speed is the RPM that a given torque converter (impeller)
must spin in order for it to overcome a given amount of load
and begin moving the turbine.
What are the differences between flash stall and brake stall?
Flash stall is the true stall of a torque converter. Brake stall, or
“foot brake stall,” is the RPM that occurs when the engine overrides the brake system, and the car begins to “push” forward.
•• 1000+ RPM increase in stall over stock
•• Efficient at highway cruising speeds and harder launches at wide-open throttle
•• Bolt-in with no modifications required
•• Designed for moderately modified street machines and
weekend racers used as daily drivers
42
LS Performance
Which one is the more effective measurement of the two?
Brake stall is NOT an accurate way to properly check the stall
because there are too many variables that affect it. When
measuring the stall of your torque converter, the flash stall will
always be the more effective option of the two.

TCI engineers have developed a complete line of
bolt-together converters for the 4L60E and 6L80
transmissions from GM. These converters feature an
increase in stall speed over stock options, thereby
increasing torque multiplication and allowing the
engine to get into its powerband sooner. The result
is improved vehicle launch and overall performance.
They are designed for extreme power, easy stall
speed changes and consistent performance.

Ultimate Durability
Benefits include a triple-disc clutch with significantly higher torque capacity and much higher
clamping force than a single-disc design, while
they also have the ability to fully lock-up under wide open throttle so there is little or no
high-gear slippage. These converters are can be
used in many high horsepower and modified vehicles when a single-disc converter simply won’t
withstand the power. Featured along with the
high torque capacity, triple-disc, woven carbon
fiber friction lock-up clutch is a 50-spline clutch
hub, meaning the horsepower capacity of this
converter is second to none. And thanks to the
bolt-together design, stall changes and service
of frictions and bearings can be performed at
home. Starting at $921.82, depending on application
and stall speed.

Racing Starter
This part is designed for drag racing and applications where
a smaller and lighter weight starter is desired. Manufactured by Hitachi for TCI, this starter is one-third smaller than
most OEM units, to increase room for headers and oil pan,
plus increase ground clearance.
Full ball bearing construction means less internal friction
and more torque transferred to the engine while balanced
armatures encapsulated in high-temperature epoxy resist
heat and vibration. A heavy-duty solenoid utilizes a contact
disc instead of a bar-type contact for more consistent starts.
An amperage draw of 210-250 amps at full starting load
provides increased spark for ignition. Starting at $289.69.

A Whole New
Another Randy Johnson Knows
How To Cut Down the Competition
He isn’t the former Major League
Baseball pitcher known for 100-mph
fastballs, but this particular Randy
Johnson can still bring the heat in
his second-gen Camaro.
Randy Johnson is certainly familiar
with second generation F-body Camaros. Owner of D & Z Customs in
Kewaskum, Wisconsin, Randy had
been a regular in the winner’s circle
for years, making this generation of
Camaro more popular with autocross
and road racing fans at every turn.
Randy already had experience building a successful second gen Camaro
that taught him plenty about how to
build a hot corner-turning machine.
He had even collected an assortment
of trophies with this Camaro in its
orange color scheme so he decided it
was time to make a color change and
step up his game.
Randy’s green machine is powered
by a 680 HP Wegner Automotive LS7
outfit with Wiseco 11:1 compression pistons linked to Callies connecting rods and crankshaft. COMP
pushrods, roller lifters and a custom
ground camshaft are hidden under
the RHS LS7 cylinder heads and
FAST 102mm LSXR intake manifold.
Photos by Robert McGaffin
McGaffin Digital Photography
To keep the fuel flowing, Randy installed FAST 52 lb./hr. injectors and
a GM ZL1 fuel pump. The LS7 features a Dailey Engineering dry-sump
oiling system and a Peterson Fluid
Systems 10-quart tank. Two-row radiator hands and a C&R Racing oil
cooler further engine cooling. Stainless Works handles the exhaust system and delivers what has to be labeled as an “angry” exhaust note.
Up front Randy installed the Heidts
Pro-G suspension that included the
Heidts prototype cantilever suspension system bolstered by RideTech
triple-adjustable shocks. To get the
680 HP Wegner Automotive LS7 featuring a
FAST LSXR 102mm intake.
correct ride height, Heidts Pro-G
2" drop spindles and tubular lower
A-Arms were bolted in place. In the
rear, Randy kept it Heidts-pure, including a new Heidts Pro-G independent rear suspension. Added to that
elaborate IRS suspension system, he
used RideTech springs and, again, triple-adjustable coil-over shocks.
Handling the intense and repetitive
braking Randy would encounter in
racing situations, he installed massive Wilwood W6A six-piston calipers and 14" GT slotted rotors to the
front Heidts suspension. In the rear,
Wilwood Dyna-Pro four-piston calipers to clamp down on the 10.25"
diameter rotors – both front and rear
systems proving more than capable
to stop the awesome green Camaro.
To hold tight to the track surface, Nitto NT05 tires measuring 295/35-18 in
the front and 335/30-19 in the rear
are wrapped around powder coated
black outer hoop with gunmetal grey
centered (and center-locking) Forgeline DE3C wheels (18 x 10 front and
19 x 12 rear). An often overlooked
handling bonus is the RideTech fivepoint seat harness that mounts to the
RideTech tiger cage, significantly increasing the structure of the car and
further aiding corner carving.
Watch for Randy to take this slick
green machine to the winner’s circle
in autocross and street racing series.

Race Winning Clutch
Street Performance Reaps Rewards From
Quarter Master Race Engineered Clutch Design
The popular adage with car companies of the early 1970s
was “what wins on Sunday, sells on Monday.” Trans Am racing
competitions of the day helped Camaro and Mustang become
the popular brands they are today.
Quarter Master brings race-winning clutch technology to the
street with Optimum-SR 10.4" LS Clutch Kits. The clutches deliver a comparable-to-stock pedal feel and are capable of handling
700-1400 HP and 500-1000 ft./lbs. of torque*.
The same holds true with clutches. Race-winning clutches have
far more credibility with consumers looking for in-the-fieldproven parts to make their drivetrains strong and durable.
With lessons learned from racing and with data from extensive
drivability testing, Optimum-SR LS Clutches feature a race
capable design now available for street use.

Those looking for a true racing clutch with factory driving characteristics will find Quarter Master
Optimum-SR 10.4" Single-Disc LS Clutch Kits ideal.
(if applicable)
This kit’s lighter weight (50% lighter than the stock
assembly) creates a reduced MOI (Moment Of Inertia), allowing the engine to rev and de-rev quicker
than a stock OE unit.
All these features knock seconds off the stopwatch,
while delivering a stock pedal feel and chatter-free
operation to serve as a heavy-duty stock replacement.
Holding up to 500 ft./lbs. of torque and 700 horsepower, the kit includes the clutch, flywheel, release
bearing and release bearing adapter*.
The single-disc clutch boasts billet construction and
is 100% rebuildable. Additionally, the unit is constructed with proprietary spring technology and is
compatible with OE-type hydraulic bearings or the
Quarter Master Tri-Lite II Hydraulic Systems. It is legal in both the Pirelli World Challenge & Continental
Tire Series but can easily be used for street driving.

KING
of LS Blocks
The RHS block, designed for radical street and all-out racing
applications, is a proven foundation for building real LS performance.
Going beyond the limitations of other GM LS blocks, the
RHS LS Race Block is available in both standard (9.240")
and tall (9.750") deck height combinations and is engineered for maximum clearance around a 4.600" stroke
crankshaft. This was done by raising the camshaft centerline (.388"/9.86mm) and including priority main oiling that
shifts the oil galley outboard. With this unique design, RHS
engineers also minimized windage in the rotating assembly – leading to superior engine lubrication at higher RPM.
56
LS Performance
To make it friendly for existing race applications, the block
contains both factory and motor plate race mounts for Gen
I, II, III and IV engines. And for quality assurance, RHS
conducts a CT scan (similar to a medical CAT scan) on each
block to ensure maximum precision and consistency. Combine that with more standard features than any block on the
market and the RHS LS Race Block becomes the benchmark
of LS power, strength and compatibility for radical street
and all-out racing applications. Starting at $4,979.84.

Lets Talk ABOUT
Debunking The Myths of Nitrous Oxide
While there has never been any question as to the wonderful power inducing performance gained by injecting nitrous oxide into your engine,
it has also been surrounded by some serious misconceptions.
So we’re here to clear the air. The following are what we believe to be the
top three myths about nitrous injection and its effects on your engine.
Myth #1: Nitrous will blow up my
engine!
Simply stated, nitrous, when properly installed
according to the manufacturer’s instructions,
will NOT blow up your engine. Nitrous is still the
easiest and safest way to greatly increase your
engine’s horsepower.
Problems arise when people realize how easy
it is to significantly increase engine power.
With today’s modern nitrous systems, all that
is required is approximately two minutes
to change the nitrous and fuel jets, which
can add an additional 50, 100, even 300
horsepower. Beginners often try to push the
window, figuring if everything appears to be
running well, a “little” more nitrous can’t hurt
their engine. But, novice nitrous users forget
to make the proper (and safe) engine ad60
LS Performance
justments in accordance with the increased
nitrous jet sizing.
The most commonly overlooked adjustments
include forgetting to retard the ignition timing, not changing to “colder” heat range
spark plugs, and in some cases, not installing an increased flow capacity fuel pump
to deliver sufficient fuel flow. The result is a
nitrous system that is not correctly installed
for safe operation, making engine damage
inevitable. As long as the installer follows
the manufacturer’s tuning instructions and
advice with regard to engine adjustments
and vehicle upgrades, they will have safe,
reliable power gains that will not harm their
engine in any way.
All ZEX Systems
incLUDE:
Fuel Shear Technology
ZEX Fuel Shear Technology injects enrichment fuel using a fuel transfer tube. The
tube allows the nozzle to directly inject fuel
into the highest velocity area of the nitrous
plume. This high-speed nitrous shears the
fuel away from the tube, atomizing it to
levels other nozzle designs never achieve.
This ensures perfect fuel distribution from
cylinder to cylinder. The finely atomized
mixture also burns more powerfully and
maximizes the horsepower you get from
your nitrous system.
Active Fuel
Control Technology
In your engine, a vacuum is created as
nitrous gas is sprayed across the open
end of the nozzle’s fuel transfer tube. As
bottle pressure rises or lowers due to bottle
temperature changes, the speed of the nitrous discharge varies to the same degree.
This causes the level of vacuum draw in
the fuel transfer tube to vary as well. This
variable vacuum draw causes the nozzle to
“pull” more or less enrichment fuel into the
engine. This means your engine never runs
too lean or too rich. The nitrous tune-up
stays dead-on for maximum engine safety
and power at all times.
TPS Sensor
For optimum safety, every ZEX kit features a
patented TPS switch to activate the nitrous
system only at wide-open throttle. It is fully
compatible with throttle-by-wire engines.
Myth #2: Blowers & turbos are safer than
nitrous injection.
A properly installed nitrous system offers virtually the same level of engine safety as supercharger and turbocharger enhancements. Forced induction engine kits are most commonly complete packages that include
fuel system and computer tuning upgrades. This allows the manufacturer to build a safe computer “tune-up” into the system they provide. But
adding all of those extras raises the cost of the upgrade by thousands
of dollars.
With a nitrous system, the manufacturer provides precisely what is
required to safely use nitrous, as well as detailed recommendations
when fuel and ignition upgrades are necessary. The beauty of this information is that the customer makes the decision as to how far they
can go with their nitrous system based on their specific upgrades. A
person spraying a 75 HP shot of nitrous doesn’t require a fuel pump
upgrade, so why should he or she pay extra for one? But a person that
wants to spray a 200 HP shot will definitely need to increase the fuel
flow as well as the ignition system performance.
When it comes down to it, a nitrous system is just as safe as a blower
or turbo kit as long as it’s installed with the fuel and ignition system
upgrades needed for the power level you wish to run.
Myth #3: Nitrous oxide is the same thing as
nitro methane.
Nitrous oxide and nitro methane are NOT the same thing – not even
close! Many people, especially those casual spectators of Top Fuel
and Funny Car drag racing, think that nitrous and nitro are the same
fuel. Having watched racers explode engines while making a 300 mph
run down the quarter mile, they believe that nitrous will also cause
their engines to blow up. Nothing could be further from the truth.
The nitro methane used in Top Fuel competition is a very volatile liquid
fuel and only racing engines designed specifically for it can handle its
huge power and destructive force. In these applications, nitro methane
is the main fuel source, constituting as much as 90 percent of the total
fuel burned.
Nitrous oxide, on the other hand, is injected into the engine in comparatively small amounts and delivers smooth burning characteristics
that enhance the fuel’s combustion process. Whether it’s a small 55
HP shot of nitrous added to a four cylinder engine or a 300 HP shot
added to a properly built V8 racing engine, nitrous allows you to add
just the right amount of power without fear of damaging your engine.

Let’s face it, nothing grabs our attention at car shows
and cruise nights better than a car with an aggressive,
hard thumping, high-performance idle. In their ongoing
quest to provide enthusiasts with the PERfORMAnCE,
SOunD & DRIvABILITY they crave, the COMP Cams®
engineers expanded the Thumpr™ series of camshafts to
include grinds specifically designed to give late model LS
engines real hot rod attitude.
Featuring specially engineered profiles for late model GM
LS engines, these camshafts provide the perfect combination of early intake valve opening and long exhaust
duration with a generous amount of overlap to maximize
your engine’s nasty idling characteristics without negatively impacting streetability. Thumpr™ Camshafts and
matching valve train parts are EASY-TO-InSTALL, direct
replacement components that exceed the quality and durability standards of OE parts. Finally, your late model LS
powerplant can provide an authentic hot rod experience.
Without question, the Thumpr™ Camshafts are in a class
of their own when it comes to serious “seat of the pants”
performance and a head-turning, aggressive idle.

The
Daily
Grind
Ordering a special grind camshaft
may be the best course of action when
building your LS engine
There is no more critical part of an engine than the
camshaft – often referred to as the brains of the engine.
The patterns and position of the lobes of the camshaft
determine the timing and lift applied to the valves and
valve train. So it goes without saying that selecting the right
camshaft is clearly the most important decision you make
after engine choice.
When it comes to LS engines, COMP Cams offers a wide
range of standard camshaft offerings. For street engine applications, these are more than appropriate. But that does
not mean they don’t invite creative camshaft requests for
more complex engine applications. Many high tech engine
builders are very sensitive when it comes to developing
their own cam designs and other valve train gear. They have
specific requirements that require special orders.
COMP Cams created literally thousands of special grind
camshafts for LS engine builders in 2013 alone. That’s a
lot of custom ordering. But that does not mean lengthy
wait times or extra costs. COMP Cams custom grinds take
less than 72 hours to grind and cost no more than a standard part numbered camshaft.
The following pages include COMP’s popular shelf-grind
camshafts. This will help many engine builders select from
a wider range of cams and lessen their development time.
But remember, if you still don’t see something you like –
your custom cam can easily be created.
