Air pess. for Nitto drag radials

[just4bob50]

I have nitto drag radials size 245/50/16 on my car. My car is lowered about 2" and weighs 3500lbs. with me in it. My best 60ft time ever was 1.94 and that was before the supercharger. now it is 2.07, I have tried different burnout techniques and tire pressures from 17psi to 20 psi. Does any one else have a car that is set up simularly. As it stands now that 2.07 was driving the car out of the hole and slipping the clutch a little. Everthing else i try just spins the tires real bad.

I ran 11-12psi in mine and did a 2nd gear burn out and went through the water box. I cut consistant 1.8's. On the street with h/c/i and a 100 shot it hooked in first gear out the hole.
