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.

Detailed Description:
Katech Performance has developed an 8.2L, 500ci engine specifically for the Pratt & Miller C6RS. The C6RS engine is the only naturally aspirated, 600 horsepower, 600 lbs.-ft. torque engine available for the Corvette. An exclusive Dart billet cylinder case with Katech specified features allows a 4.500” stroke while improving material strength over cast production blocks. With no liners, the Nicom spray bore reduces friction and improves heat transfer to better cool the cylinders. An all-forged rotating assembly replaces an LS7’s components with higher strength materials. LS7 heads, valvetrain and dry sump round out the package.

Katech Performance finishes the C6RS engine with its standard show-prepped intake manifold and aluminum valve covers. 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 engine, devoid of plastic covers, is an elegant expression of form and function.

Brief Description:

Who made the coil relocation brackets for this car, and do they sell them?

 

Katech does... visit their site...

 

600/600....nice.

 

They are made by us exclusively for the C6RS. They are not for sale. We do sell our original coil relocation kit.

 

Nope I am looking for the one on the C6RS, side mounted coils.

 

Thats awsome! How much for this setup in my Vette?!?!?

 

They are not for sale.

 

If you are asking about the valve covers, please visit our website.

That motor is a work of art

 

I am wiping the drool off of my keyboard now. Anyone want to buy a sweet C5?

 

Im talking about the entire motor setup! HAHA! Just curious... if this setup was offered to the general public from you guys, what would it cost?

 

It is not offered to the general public so we have not established retail pricing.

 

Umm.. well this engine info was made available a long time ago...

I thought you (Katech) now had the engine itself (possibly for sale - for an undisclosed amount) available....

O...k....

 

Sorry. I thought you were still talking about the coil brackets. The C6RS engine is exclusive to the car. However, the Street Attack 500 is now available. You're looking at around $34,000 with an LS7 core.

 

Thats prettey awsome!

 

What parts do you guys use from the LS7 core?

 

With a 4.5 stroke, I assume the block does not have a standard LSx deck height. With that much stroke, that thing should be a torque monster with it hitting almost instancely. Do you have a chart of a dyno pull?

Keith

 

Everything but the crank, rods, pistons and block.

Yes, it is a taller deck height.

Stay tuned for press releases and dyno information.

 

Has any one seen a side mounted coil kit. I know of a few people that sell the top mount kit. Its so much cleaner with the coilson the fender wells.
