thanks josh
Tire pressure is way too high and slip the clutch slightly to revs up. That should help reduce wheel hop. TP should be around 21 psi....

90% of guys tend to end up in the 20-22psi range with their tire pressure at the track. Some have luck with higher pressures but most do not, like yourself.

I was at 20-21 psi and I did back to back 1.57 60fts after a 1.8 with 30psi. Even though its all wheel drive tire psi still makes a big difference.

So does a nice suspension with the proper spring rates, adjustable ride height to preload the wheels that need it and also struts that allow you to adjust the rebound rate. Not to mention camber tweaking, gotta keep those babies on the ground with a flat contact patch while launching and distributing the weight more equally to the front and back. Ask Dynoflash Al, this was his first year with a tuned suspension at the DSM shootout and his results speak for themselves.

Yes that also makes a big difference. I was just saying tire psi makes a big difference. Well it did for me at least. I have ran my car at the track maybe 20-30 times with 1.7-1.9 60fts. Then I saw this thread and lowered my tire psi to 20 and right away 2 back to back 1.57 60fts.

what tires do you have? Where is your 2 step set at? and how much boost are you building on your 2 step? Im still on stock suspension so i dont know how much better i can get my 60ft

plenty of people do amazing 60' times with the stock suspension (I hate them all! lol) but improving the suspension down the road will just make things even better. I don't recommend anyone using Nexen tires though......terrible tire for the track.

I have the falken azenis with 255 width not the best tire for the drag strip but they are great on the road.

I have Michelin PS2s. 6k 2 step and around 8-10psi. Im on the stock suspension also. My tires probably have a lot to do with it also.

I agree, Indy evo lowered his pressure before he ran his 11.84. before the pressure adjust he ran 11.9 . even after his good run it was going to be an 11.7 coming, i will try it next time we are at the track.

ok thanks i will drop to 20 psi all around next trip out and hopefully get a 1.5 60 but thats rough with a 6 speed the one to two is so quick and thats what makes my 60 times as for suspension stiffer up front and a little softer in the rear?

Ran today at island dragway 20psi tire preassure. Spun so much the car went sideways. Still managed a 1.73 60ft. Maybe its my falken azenis tires. im going to try drag radials or all season tires to see if i get more grip

My buddy pulled a 1.59 on General Exlaim UHP's today! Pretty crazy for a all-season tire if you ask me!
