Hoosier Quick time pro's pressure at track.

[onefastjackass]

I went to the track yesterday and had problems getting traction.

It might have been the lane Or track but I thought I would ask the question about how much pressure are you guys running and how much of a burnout are you doing??

I tryed from 22 psi down to 17 psi. Should I go any lower??

I was launching at about 15 psi of boost and they would spin a few revolutions and then catch with a loud chirp. then I was gone but still would like them to grab better.
What do you think??

take 'em down to 12

if they still spin, get some real slicks

depending on how they handle, you can prolly find a happy medium somewhere around 13-15

I usually start with mine at 15# and slowly go down in pressure, sometimes as low as 12#, as the track goes away. I also leave at 14# of boost - I can't hold more at the line. My usual 60' is in the low 1.6 range with a best of 1.56. I want to keep as much air in the tires as possible as I hate the dancing the car does at the big end when I lower tire pressure under 12#.
