Yesterday I took out my 2011 gt with a 2.3 Whipple out to the track. The DA was nice at 780. The best pass of the day was a 11.913 at 121.81. My car ran 11.9 at 119 with a CJ setup on the same tire. The car is trapping only 3 miles more with 7psi. Car has no cats, 2.3 whipple,lu47 and 3.375 pulley that is making 7psi right now with a roush CAI. I think my trap speed is weak for the extra power the blower should be making. The A/F is at 11.4 and the timing is at 16 when I dataloged for tuning, I did not datalog at the track. What trap speeds do you guys see with a similar setup on a 6speed MT.
