Hi guys, what tire pressure would you recomend to run when launching on M/T drag tires?

 

gonna need alot more info then that buddy...

 

If your new at this, I would tell you to start where most guy's seem to, about 8-9psi then walk the pressure down so you get a feel for how the car moves at the top end of the track.

Don't just jump to low pressure. Better safe than sorry.

 

when i used 24.5's, they usually end up at about 6psi. i use the m&h 26" now and i usually end up with alot higher pressure

 

now I'm running it at 8 psi.... but I tried it at 5 and didn't fell the difference on the start. Only thing I felt that it was hard to stear the car on high speed. I turn the wheel to correct the direction, but she keeps on going the same way she wants So I got scared and I went back to thos 8 psi.
But still what do you peeps run? the track is without rubber.

 

Sorry to thread jack, but are you people using tubes or going low pressure off the tire alone? Bead screws?

 

no tubes here, but with rim screws

 

the last 2 sets of slicks i've had mounted have not been holding their air. after 2 or 3 days they're completely flat. i think i'm gonna start using tubes to avoid that.

OP: how much hp does your car make?

 

Yeah mines do run flat without tube in few days too, but they hold the pressure during the race day and that's enought for me.

I don't know the exact power of mine, but I do run ~12.5 (best 12.39) but still I want to improve my 60 ft as for now best was 2.03

 

what size are they? thats a terrible 60ft with slicks. you need to launch at higher rpm or something. with an average 60ft you'll be in the 11's so i'd say 8psi is a good tire pressure.

 

What do you have for traction bars, and suspension set up?

 

It's not honda, standard ARB, standard gas shocks and springs.
