most of the been there done that guys use the math
its how nhra factors cars and classes
you weigh this much you run this mph in the quarter you have x hp
if you weigh this and have x hp you should turn x et
everything else is tune and hooking
if you turn 107 in the quarter and run 14.0 you car is slow in the 60 foot bad 1st 100 feet but your 107 should be a mid 12 in an abody
the guy you are racing only tuns 100 mph but has a 1.9 60 foot you will be looking at his tail lights he most like beats you with a 13.6 ish
mph is what matters the rest is hook and tune
the car meet crowd say they 550 hp but the have 600 with secondarys
no offence mr rumble
