you have to look at 2-3thing 60foot time are the the most important thing if you want to run great time
a really nice 60foot will make a real nice ET but you'll have less trap speed
when you spin tire ofent you'll have a better trap speed but a slower ET
there are some Hp calculator you enter car weight and ET or trap speed
like me best 60feet as 2.308 wich is not that good and best MPH was 86mph with my tib stock i ran 16.26 !!
with a better 60' i would have ran 15 hi..... you can tell that with the trap speed of 86mph
hope that help you a bit !!!
