The N.H.R.A. drag racing rules that are applied at the track I go to state that a convertable (wich I own) can not go any faster than 13.99 without having a roll bar installed. I don't want a roll bar. Last year I ran 14.4 with 3.73 gears and now have installed a prochamber,underdrive pullies,Accufab plenum and 75 mm throtle body and deeper gears. Although I haven't been to the strip yet,I believe I will be close to 14.0 flat now.
