We just completed a customers car last week that i even suprised my self on. The car is an 07 c6. It came to us with 1 3/4 kooks headers, 410 gears, ccw drag pac on a 27 inch tall. I figured with those mods it will kill the power some esp with those tires and 410 gears.
We added 225 Trick flows milled to 59cc and added our RPM-3 cam on a 112+2. We cleanup the porting that was already done on his Fast 92. We added an underdrive pulley and 60# injectors also. He already had an electric water pump.
We also added an RPM Transmission and an RPS Street Twin Clutch.
I told the customer i would have been happy if the car made 480rwhp with those mods... Well first pull was 475rwhp and it was VERY rich... Here are the final results.
Here is some shakedown runs we did.
Look how easy the launches are. I feel this car will easily break the 10.81 H/C LS2 record.
