2002 Gt2 Dynojet RWHP results

Put her on a dyno today for a baseline before any modifications. These are hp to the wheel numbers. It was about 65 degrees and low humidity. I couldn't believe these numbers either. I felt like a proud father.

what correction factor did they use.. that can sway things a bit... plus dyno jets tend to be generous on HP... either way it is what it should be...

TPC in Jessup, Md ran her on the dyno for me. That's HP to the wheels. Mike Levitas, who won the Rolex 24 hours at Daytona in a Gt3 predicted 440 hp. He was right on. He told me stock Gt3's normally pull 355 to 360 hp to the wheels, so he wasn't suprised that a 2 pulled 444. The numbers are corrected for air temp, humidity, elevation and some other variables I'm not sure of, it's a pretty nice dyno. Uncorrected the numbers were higher, 460 plus I think. But those numbers are not accurate.

We conducted a few more runs a hour or so later and she consistantly pulled 435 to 440, so I believe the numbers are as accurate as can be, short of a trap speed. As for modifying it, just going to flash the ECU for now. I'm hoping for an additional 60 to 70 horse to the wheels. Taking it one mod at a time. Put on some lower rear tow arms and that made a huge difference in stability and how straight the car tracks. The best 450 dollars I ever spent.
