Its all in the launch and 60ft..If you got a 2.5 60ft, thats not good..A "good" 60ft time for us FWD would be a 2.0, and if you can get that, that would bring your end ET to a 14.5..yeah, a full second..For every tenth you take off your 60ft time, you loose 2 tenths on your end 1/4 time..A 14.5 for 5 psi would be pretty darn good i would say..but you need a good launch, 60ft, and quick shifts..I usually short shift first, just enough to get the car moving a bit, then shift to second,go till around 6500, then hit third to around 6800, then just a bit of fourth gear to pass the line..
