550RWHP C7 Corvette N/A LT1 Build - VENGEANCE RACING Heads Cam Package Car had longtube headers, cold air intake, and E85 sensor installed previously by another shop. The customer did not have a very good experience with his initial build, so decided to call on the expertise of Vengeance Racing to not only fix the current tune, but also install a heads/cam package to bring the most out of the car in naturally aspirated form. Customer drove the car down from Cincinnati and flew home during the 1 week build/tuning process. VR baselined the car at the 460 number that is listed first on the dyno graph, and that was with 27% ethanol showing on the flex fuel sensor.
MODS:
Vengeance Racing Stage II Gen V Camshaft with 33% fuel pump lobe upgrade (deletes AFM/retains VVT systems)
Vengeance Racing dual valve spring kit
Vengeance Racing hardened pushrods
C5R timing chain
CompCams Trunion Upgrade
Vengeance Racing CNC Ported Cylinder Heads
CompCams 850 performance lifters
CompCams phaser limiter kit
The car finished with the 2nd set of numbers on the graph with the same 27% ethanol in the tank that it arrived with, and the last set on 67% ethanol. We have no doubt that the car should be over the 550rwhp mark with a good fill of 80%+ E85.
Big mentions on this is the very high horsepower for a stock bottom end N/A LT1 build, as well as the customer coming in all the way from Ohio for his build and was able to drive it home over 8 hours just a week later.
