What tire PSI do you run in a Mickey Thompson E.T. street?
Thanks,

What ever the tire manufacturer recomends

 

Nice.

 

What did you expect, tire pressure depends on allot of different things, did you ever notice the guys taking track temperatures, watch how much fuel they put in the car, setup there suspension ? ? ? ? The tire pressure is checked and changed on a by the run basis till you get what works, all this is documented so you can look back at your setup and avoid having to relearn everything all over again, I can give you a number but you'll still have to experiment on your own and learn what works for your car. So now what would you like to hear. You question is very gereral and vague, I think my answer fits your question.

 

Nice again...

A good place to start is between 14-16 psi.

Thank You Andrew.

 

Thanks for trying to help, but i needed it a little more narrowed down to a PSI. Now I document a run from 14-16 PSI based on fuel in tank ,suspension and other track conditions.This now will help me with my goal;Hence low 60ft pass numbers.

It'll get even more complicated, your tire pressure will also determine your launch rpm, vehicle weight will also figure in, you need to keep as many of the things you can constant. I.E. if you remove your spare and anything in your trunk, you need to do this always, as if you change things in the car you will need to play with your tire pressure to compensate, cool track, warm track, hot track all have different effects on the tires grip. If you decide a certian rpm is what you need to leave at , say to keep the car from bogging. You'll have to vary your tire pressure to say eliminate wheel hop. It will be a very interesting learning experiance (but quite fun) doing it as you'll then find yours, (and the cars) weakness's. Best of luck to you and most of enjoy.

 

Thank you, Cantgostaight for your help.

The slicks will be one of the best things you do to get your 60 ft. times down. The hardest thing to do is get our cars to launch well. Wheel hop was one of the worst things I encountered (running street tires) and finding a good launch rpm. It was in most cases better to bog the car in first gear just to keep the tires from breaking loose in first, limit the boost in first and get the car moving before trying to get the power down, (our cars suck for torque) but in first and on the turbo's it's hard (damn near impossible) not to spin and start the wheel hopping process. Any way slicks should help allot in that regards but you still have to find the right combination of air pressure, rpm and boost to get the car down the track as smoothly as possible to be consistant. Enkoy and give us a run down of your learning curve. Then when someone else ask's what air pressure ? ? ? you'll have the answer for them. !!! Take care and by all means have fun, don't break anything, and go fast.

 

i run 14.5 psi in my bfg drag radials, i found that this works quite well. I havent tryed lower yet, but i have went done a little at a time from 20 till i found what worked.

 

Best 60 with bfg drag radials was at 16 psi 1.72. Full tank of gas,4.10 gear and no junk in my trunk.

 

Consistat good 60ft time is the goal!!
