Performance Partners
Corvette Performance Parts
For the highest quality in performance we dyno test all components such as intake, throttle body, headers, and exhaust systems to make sure what we install on your car is the best in the market. We have your heads ported to the highest standard in the market or use after market heads such as All Pro which is a leader in the industry. All of our cam shafts are custom ground and are tailored to your needs. We want to make sure that you get your money's worth and the performance you are looking for.
LS1/LS6, LS2/LS7 & LS3/LS9/LSA Ported Heads
These CNC ported LS6 heads, which flow 313 cfm at .600 lift would be great upgrade to your corvette's engine. We have had gains as much as 40-50 rear wheel hp from these heads!
All Pro Heads
If you are looking for the absolute best with the highest flowing numbers, the "All Pro" Heads would work great with larger displacement LSX engines.
Stroker Engines
We don't have to tell you that cubic inches is cubic power and that dictates to torque. To get torque you need cubic inches. You can add a Stroker Engine to any of our systems to increase the potential of your corvette's engine. In layman terms, "Why make the engine work harder?"
Ported Throttle Bodies
We believe that the throttle body air flow is an important factor in the engine's ability to breath. Porting a factory corvette throttle body eliminates some of the restrictions in the casting and the throttle blade which in terms will help the flow of air into your engine. With additional modifications such as heads and camshaft, this modification will benefit the performance of your engine. For larger engines we recommend after market performance corvette throttle bodies specific to the application.
American Racing Headers
We want to welcome American Racing Headers to our new line of exhaust systems. The quality and workmanship of their headers and X-pipe meets our high standards. Recent tests of their headers on a C6 Corvette netted us 30 horsepower and 25 lb/ft of torque! The new ZR1 Corvette and LSA equipped CTS-V produce even more showing a monstrous gain of 55 horsepower and 50 lb/ft of torque!
Pneumatically Operated Nitrous Oxide Systems
Up to this point nitrous oxide was not part of our corvette performance program. But with our company research, we have found the solution for reliable corvette nitrous systems with extreme potential using pneumatic operated technology. We build the nitrous systems using these pneumatic solenoids, that can be tailored to your needs. These solenoids have had zero failure rate. Another benefit of this solenoid is they can be manually operated or if activated electronically up to 4 stages will draw only 1.2 amps. 150 psi of C02 line pressure will assure a fast and reliable solenoid operation.
