There are several things that are

enthusiasts standing at your door
to buy it. Likewise, many of those
who waited patiently for their
chance at the ultimate car will
use it as a launching point to build
Katech fills the void between upon, increasing the performance

CORVETTE enthusiast
Katech knows these people well.
They have been intimately aware of
Corvette’s performance potential since
they started building racing engines for
the factory C5-R Corvette Racing team.
The durability and performance they’ve
built into every C5-R and C6.R engine
has helped keep Corvette Racing at the
head of the pack and has cemented
a great relationship with the team
and crew at Corvette Racing. Recently,
Katech Performance has sought a
similar relationship with the owners and
enthusiasts of street-driven Corvettes by
doing what they do best, building upon
the potential nestled between the frame
rails of every late-model Corvette.
While their racing engines are proven
winners on the track, Caleb Newman,
vice president and director aftermarket
operations at Katech, is quick to point
out that the needs of a street engine
are quite different from its full-race
counterpart. That is why Katech Engines
expanded into Katech Performance. The
same folks who assemble the racing
engines wrap their hands around the
street-going version, but these
are designed for maximum performance
for the long haul, not just 24 hours.
Designed–a word describing all they
do to ensure that every engine carries
the same durability and maximum
performance potential, whether found
on the street or the track. Committed
to finding out what works, what
doesn’t and why, every proposed
engine package finds its way on one
of Katech’s seven test cells to prove if
it has the right stuff to wear the Katech
logo. The ability to simulate where
the rubber meets the road, coupled
with the most modern testing and
engineering techniques, ensures that

each engine package works to its fullest
potential and just as described. From
that starting point, Katech Performance
was able to devise several packages
to fit their customer’s needs. Starting
with the proven LS7 engine, Katech
Performance offers their Attack line of
engines. The Sneak Attack starts off the
line with a “sleeper” engine with an
8,000-rpm redline. The Street Attack
engine package maintains compression
at 11:1 and is the perfect choice for
high-power daily drivers. The Track
Attack goes all out with 12-14:1
compression and is designed for
off-road/track use only. For the forcedinduction crowd, an Air Attack LS7
engine features a lower compression
ratio and a camshaft designed for that
specific purpose.
Our feature Z06 just received
components for a Street Attack LS7
package–we had the opportunity to
experience its new-found potential firsthand. From the minute you press the start
button, there’s no doubt that this package
was assembled with performance in mind.
The exhaust note through those Corsa
pipes exudes power and aggressiveness.
The Street Attack package will boost
1 More than just a pretty face, the LS7 gets treated
to years of experience and engineering under those
Katech Performance valve covers. Color matching is a
trademark of Katech Performance and even flows over
onto some of the aftermarket parts that Katech offers
like the belt tensioner.
out for this full width, carbon fiber version. Other than that,
factory-fresh was just fine so far as aesthetics were concerned.

horsepower in excess of 600 and give
over 570 lb/ft of torque at your disposal.
Interestingly, while driving around
Katech’s homeland of Clinton Township,
Michigan, we noted that the performance
envelope was expanded, but the modest
side of daily driving, where compromise
is usually made, didn’t suffer noticeably
from the increased power. Granted, you
won’t be keeping a low profile while
driving one of these packages, but if that
concerned you, chances are you weren’t
looking for more horsepower anyway.
On top of the hard parts sealed into
the crankcase, Katech Performance also
combines exhaust and induction packages
depending upon the customer’s request,
and also offers body modifications to
help make your Corvette stand out from
the crowd. They offer a front splitter, rear
spoiler or wing, and a world challenge
louvered hood to give your Corvette that
racing appearance. The Victory Red Z06
that we experienced during our time at
Katech went so far as to have their full
width carbon fiber spoiler installed, but
kept to the factory original skins–making
its statement in deed, not appearance.
To complete the entire package,
Katech offers special packages featuring
emphasized by the coil relocation kit and the Katech
Performance valve covers. Additionally, you can see the
ceramic coated Kook’s headers that Katech offers with
their engine packages.
4 Katech Performance has spent considerable time
validating camshafts for their packages and offers
a variety of profiles according to the engine’s
particular needs.
5 The LS7 head is one of the best breathing designs
GM has ever produced and is used exclusively on
the Katech Performance Attack series engines with
great success.

a Ron Davis radiator with an additional
oil cooler and, to make the most of the
Z06’s transmission, an RPM Transmission’s
Stage IV upgrade is available as well as
a shifter for added performance. Even
though each package is custom tailored
to the customer’s request, every one done
by Katech Performance gets a special
serial number plaque and documentation,
verifying its origin. You can either enjoy
your additional performance wrapped
in the factory furnishings, like our test
drive vehicle, or you can opt for the
added elegance of Caravaggio’s handstitched interior parts to set off the inside
of your ride. For additional braking, a set
of Brembo brakes can be added to the
package to keep the balance of power
between go and whoa.
With 505 horsepower available from
the factory, one might ask why someone
would feel compelled to put more
horsepower under the hood of their Z06.
Much like that desire to own the ultimate
sports car, their urge for more tends to
take them on a voyage from factory stock
to being fanatical about horsepower.
And thankfully for them, tuners such as
Katech Performance are there to help
them along the way. n

lighter than stock units for the LS7.
8 Katech has a dyno cell designated mainly for
valvetrain evaluation and testing. They offer beehivestyle springs due to their being consistently more stable
due to the reduced natural frequencies and lower mass
at the top of the spring. This makes them a great choice,
even on the more radical camshafts.
with a Ron Davis radiator and plumbed with
Goodridge lines.
7 The LS7 engine makes use of high-tech metals like
titanium and, in true Katech fashion, they go one step
further. To ensure ultimate reliability, Katech replaces
the split-bushings used in the LS7’s connecting rod with a
solid bronze bushing for the additional strength.

onto the side of the block and is used in conjunction

10 This is how fresh our Z06 test car was! When we
were introduced to the car, they were just putting
the finishing touches on it–like adding the window
decal. There were several Z06s in their shop that
were delivered to Katech and still had the plastic on
the seats.
