Ok, last year with my setup below with street tires, 2.73 gears with a 7.5 open differential rearend I ran a best of 13.78@104
This year I added an 8.8 with 4:10's, M/T slicks(26x9x15) and subframes.
My best time was a 13.47@103.53
I feel I should be in the 12's and something is holding me back and can't quite pin point it.
My best 60' was 1.97, which I feel could be lower. I ran 12lbs of pressure in the slicks.
What do you think is the "bottle neck" in my setup?
