Now My car is light ,I say light at under 3000#, The 60 does not care if it is 3500 rpm or 2000, only couple # different ,so I leave at 2500, I think a lot has to do with the combo , air in tires, converter, cam, and gearing, Trans brake could make some difference, more so in RT than et? ,

Its when the light turned green to when the front tires broke the beams(forward beam)... think of this extreme. if you idle off the line to 5000 rpm off the line.. which will move past the beam first

Next time I go out, I will go back to my "normal" launch procedures ( tires at 12 psi and launch at 2700rpm ) and see if my RT's return to - acceptable . Fastest 300
