Make sure you go high enough and then back the pressure back down to it's optimal setting! Ideally, you would like to have the pressure as high as possible without negatively affecting the performance of the vehicle.

I had been running mine between 5.5 - 6.0 psi, but when I switched to M/T and subsequently Hoosier, I found that I could run 8 psi no problem (it's a smaller tire on a 4-link car so I wouldn't necessarily expect the same pressure on a HT dragster with a bigger tire). I never would have thought that I could go that high, but I just decided to keep going up until I saw a dropoff in performance. My dropoff came at about 9 psi, so I settled on 8 psi as a safe pressure.

Anyway, good luck, and look forward to hearing the results...
