KATECH PERFORMANCE SUPER ENGINE POWERS C6RS SUPERCAR
8.2-liter, 500ci V-8 Produces 600 Horsepower, 600 lbs.-ft. Torque

CLINTON TOWNSHIP, Mich. – Katech Performance, drawing upon 30 years of unrivaled engine building expertise and more than 50 driver’s and manufacturer’s championships in the world’s most prestigious racing leagues, has developed a revolutionary 8.2L, 500ci, all-aluminum, naturally aspirated engine to power Pratt & Miller’s all-new limited edition Corvette C6RS. The extraordinary engine is making its debut this week at the 2007 SEMA Show, where the C6RS super Corvette is on display in the General Motors exhibit.
Since 1989, Katech and Pratt & Miller have partnered on many race programs including the American Le Mans Series (ALMS) where their efforts have propelled Corvette Racing to unprecedented success since 1999. Katech’s pioneering 8.2-liter engine allows the C6RS – inspired by the seven-time GT class champion Corvette C6.R race cars – to combine advanced racing technology with the refinement required for everyday drivability.
“Pratt & Miller approached us with the challenge of producing an all new supercar engine,” said Caleb Newman, vice president, director aftermarket operations, Katech Performance. “A tuned production engine isn’t fitting for a vehicle the caliber of the C6RS – it must be best in class drivability, horsepower and torque – and we all agreed, naturally aspirated. Extra weight on the front end isn’t acceptable on a sports car, so an all-aluminum platform was required. To meet this challenge, more displacement was our first choice. The 8.2-liter C6RS engine is a dynamic evolution of all of Katech’s expertise in racing, performance and production engine development.”
The small-block V-8 displaces 500 cubic inches to infuse the C6RS with an awe-inspiring 600 horsepower and 600 lbs.-ft. torque. Katech commissioned Dart to build an exclusive high-strength billet 6061-T61 aluminum block that, with Katech specified features, allows a 4.500” stroke while improving material strength over cast production blocks.
Liner-less, Nicom-coated 4.205-inch bores reduce friction and improve heat transfer to better cool the cylinders while the all-forged rotating assembly replaces stock components with higher strength materials including a forged steel crankshaft and connecting rods as well as 11:1 compression forged aluminum pistons.
Exclusive to the C6RS are all-new coil relocation brackets moving the ignition coils to the side of the engine for a clean, tidy appearance. Mated to Pratt & Miller’s all-new carbon fiber air box, the 8.2-liter C6RS engine, devoid of plastic covers, is an elegant expression of form and function. LS7 heads, valvetrain, dry sump and Katech Performance’s standard show-prepped intake manifold and aluminum valve covers round out the package.
The Pratt & Miller Corvette C6RS (www.prattmillerc6rs.com) – on sale beginning April 2008 – also features a purpose-built carbon fiber body, functional front fender louvers, integrated rear spoiler, computer-controlled adjustable suspension, T56 six-speed transmission, twin-disc clutch, BBS forged aluminum wheels, Michelin Pilot Sport tires, Brembo monoblock disc brakes, two-tone leather interior, comprehensive Dynamat sound insulation system and a premium stainless steel CORSA exhaust with patented Reflective Sound Cancellation™ (RSC) technology to achieve a crisp, bold exhaust note and “drone-free” in-cabin experience.

simply badass. probably has pretty good street manners too. don't suppose u could post a dyno graph. i bet the torque curve is rediculus

It has excellent manners considering the emissions legal cam that is in it. We have not released dyno graphs yet but stay tuned.

Any particular reason (besides bore spacing) for the really long stroke? I'm assuming that is what limited the redline to 6200 RPMs...and at that low of RPMs, would a dry sump really be necessary? Just curious...I'm sure somebody much smarter than me answered those questions a long time ago.

Oh...and what would the overall longevity of the cylinders be without the iron liners and just the Nicom? Would the wear rates be the same as an iron liner, better, worse?

Not necessary, but definetly worthwhile. I've seen 4.500 stroke BBC engines with a wet sump system gain 7hp just draining 1 qt of oil.

At 6200 RPM, those crank journals are spinning at over 7300 fpm, which is about the same as a stock 3.622 stroke crank turning 7700 RPM.

Just curious if you could clue us in as to how mild the cam is. I rode in SAM's 500ci LS2 and it was relatively docile with a 23x cam. If it weren't for the open headers and powerglide, I'd drive it pretty regularly.

The reason for the long stroke - cubes. Dry sump wouldn't be necessary, but since it is designed for a Z06 and based around LS7 design, it stays.

This is a tall deck block made exclusively for Katech.

Better. The LS7.R race engine has Nikasil bores (same idea, different manufacturer) and has proven to be EXTREMELY durable in 24 hour endurance racing.

Mild as in stock production cam.

That is an LS7 intake.

It is a billet LS style block. It shares the same exterior dimensions as the LS7, but with a taller deck height.

I can only guess that it's going to cost well into the 6-figures, but well worth the money in my oppinion.

Also, any guesstimate on the weight of the car. I know you guys (Katech) were responsible for the motor, but with all the liberal use of carbon fiber I'd have to speculate that it dropped close to 100lbs off the base Z06, possibly getting it close to that sub 3000lb magical mark.

Does it have spacers for the intake??? I am just not understanding how the ls7 intake is fitting on a tall deck block..
