I haven't got a clue what those 'up'grades would do but a showroom stock Buick GN was in Norwalk Oh. in 1990 running hi 12's and low13's with a slow reaction time due to the young mans inexperiance. With a better/ skilled driver that car may have run 12.3 quarters,

...but that is just my thought

I don't have direct experience with 4 valve cobras but here's my guess.

cold air intake = 5 - 10 HP
long tube headers = 15 - 20 HP
3.73 gears = .2 tenths
aluminum drive shaft = 0 - 5 HP
diablo programmer = ??? guess maybe 10 -20 HP tops

HP totals to about 30 -50 extra plus the gears. So he probably picked up about 5 to 7 tenths.

I've run into a number of racers that think that a better reaction time means the car would be quicker but reaction time has nothing to do with how much time it takes to run the quarter mile. Reaction time is how long it takes your car to break the beam to begin timing the run.

Easiest thing to do is to take your car to ESTA and find out for yourself. ESTA dragstrip is located just of Rt. 31 in Cicero

I need my truck tuned and then go back to the track With no tuning but in driveway with the open 10 bolt my truck went a best of 14.8 @ 92 with Really horrible 60' times b/c the 1 tire would never hook. Im hopin without tuning now with the 12 bolt i can get a mid to low 14 with traction then tuning and be in the 13's.
