BKAT I run 24/25 psi and leave somewhere between 5 and 6k, don't know exactly as I'm too busy timing the light, just go by sound. All the talk about stock axles breaking comes from the sudden jolt of torque from dumping the clutch. It's important to find the point where the clutch engages and ease your foot off the floor when staged. I'm cutting 1.69-1.75 short times by slipping the clutch and am just fine with the stock axles. Slipping the clutch also keeps the rpm up so no bogging. No bogging, no spinning, that's where it's at. Also, If you're leaving right there's no need for NA cars to run lower psi with DRs, it will only make you bog. I did an experiment and started out at 28 psi one day and dropped it by a pound ea. pass till I had no/very little spin. Sorry for the book, hope this helps.
