It also depends how a car is setup . I beat a lot of cars that did better or almost as well as me in the 1/8 in the 1/4 because they were better suited fot it.
My best 1/8 with 516/452 was only a 7.2 @ 100.69. But I can pick up over 30 mph in second half.
If I only raced the 1/8 most of the time I would run 4:10/4:30's gears instead of 3:73's for example. Plus I need some more improvement on my 60's and shifting.
mine really isnt setup for either lol. a 4.10 is way too much with my kb lol i struggle for traction on the street even with teh 315s out back. lol its just my street car and the only reason why i do 1/8th is beause its about 20 minutes from me lol i want to hit mir this year.
but yea your right its how the car is setup. kbs dont do so well on the top end like the centris.
