I went to Lebonon Valley Drag way on Sat morning for the test and tune.Weather was mid 80's and humid. 1st run M/t drag radials(275/50-15) at 15psi, 25lbs boost,8psi launch,ran 13.28 at 108,2.3 60 ft,no traction
2nd run 13psi in tires,5 psi launch with e-brake yeilds a 1.7 60' time and 12.70 at 111mph.3rd was same setup as the second run but tires at 12psi and heated the crap out of tires.That got me a 12.00 at 112 with another 1.7 short time. The last run we turned up the boost to 28psi and lit the tires up in 3rd!!!! Still ran a 12.07 at 111. I was really hoping to get into the 11's with the drag radials but maybe I will need a much cooler day to race on.The car is still running rich(O2's in the 790 range wot)and maybe could use more timing also. Had to change an O2 sensor before we headed up but otherwise the car ran flawless and never showed any knock with 93octane and alky at 28psi!!!!!!!Had a great time and met a few other GN owners playing with their cars.
