18’s that are 36lbs a piece and a m/t s/s tire, 285/40 (27” tall)

I'll take a stab at it. My guess is 11.9 in the 1/4 mile

Let us know how you do

HCI2000SS 06-25-2018 06:51 PM
With that tire and wheel setup I'll say 11.5-11.8 at 120-123 in decent weather and track conditions

I don’t get it, I’ve been 10.4 at 124 in a different car.

Almost forgot about this thread. I definitely think it’s got a .3 in it, maybe a .2.
