Default Hoosiers QTP, what kind of 60’

What kind of 60's are you guys cutting with QTP’s and what air pressures do they like?
I have 26x11.5x15, what can I expect.
Had them out once and spun to 1.73 (15psi)

I'm running the 26x10.5x15 at 18psi with my rear shocks set on 4 or 5 and the fronts set on 1 or 2. They dead hook as high as 20 psi but seem to like 18 the best. Going lower hasn't seemed to help any.

SlickVert I have a stock suspension with swaybars removed and a airbag in the right rear spring. I set the airbag at 20#s and the rear tires at 20#'s also. Frank95z

These tire on my M6 setup like low pressure!
Here is how my 60 went.
Does this sound right?

60’s 1.70
Shocks front 3 stock springs, rear 5
Tire 15psi
Launch off Two Step @ 5,000

60’s 1.66
Shocks front 3 stock springs, rear 5
Tire 13psi
Launch off Two Step @ 5,800

60’s 1.64
Shocks front 3 stock springs, rear 5
Tire 12psi
Launch off Two Step @ 5,800

Next time out I will try launching off the two step @ 6,000 rpm and keep lowering the pressure until get my best 60’s, then start tightening up the shocks.

Stick shift car N/A Heads n Cam 421RWHP through a 9" 3500lb race weight


28x11.50x15
Cut a few 1.57s with a string of 1.59s

All of which were in between 1.7 and 1.8 60's

They hook but not consistently on my car.

Switched to ET-Drags and cut 1.57 all day long.
