Tire pressure for track

[Shiroelex]

Opening day is tomorrow at my track, and I was wondering if I should drop the pressure in my BFG DR's at all. I'd be doing this once I got to the track. I know it's not something you do on street tires, but I figured I'd ask, since I have drag radials.

I brought it down to about 17psi for my fastest run (KDW II'S). It's nothing standard, the lowest you can get away with while not bogging, or as low as you like if it's an auto

I run my bfg drag radials at 11-13psi. Im sure you want to run more than that with an auto. A little bit of wheel spin is much better than bogging.

I would suggest around 16 to start off with.

FWIW, I run my Nitto dr's at 18 psi. They roll over a couple of times and hook, leaving between 35-4000 rpm.

I ran 17 lb my dr's

Thanks guys. I'm gonna try 15lbs and work around there. It's a 5 speed with a piece of crap clutch.

I ran a 13.9 when my car was stock after i lowered the pressure on my street tires to about 25

when i ran my 12.2 i was @ 17 lbs

Yeah I also think anywhere between 13-17 is the best. I have had my best times at 13. But every car is different.

Well, I made 6 runs yesterday. I started at 15psi and it was ok, but once I dropped it down to 11ish, they really bit. With 15psi, I would get a little spin in 2nd and a chirp in 3rd, but at 11psi, it was a chirp in 2nd and 3rd bit.

Ahhh........you can't leave us hanging like that! What kind of times did you pull?

I made another thread about it. My best was 13.6@101, and there is a TON of room for improvement! I'm going back Wednesday to try some different techniques. I'm not sure when to shift, though. I'm gonna try 5500 the first run and see how it goes.
