I am taking my car to the 1/4 mile track this friday after about a year since the last time I went. I just need to know what psi do you guys normally set your dragbags and mt et streets too since I forgot what I used to set them to . Thanks

Try your bags at about 3-4 psi on the drivers side, about 8-9psi on the passenger side and start with about 16psi in the tires

I always started around 15-20 in the bags and adjusted them from there.

Tires were normally 15-18lbs. But you're an auto so you can definitely get away with more air and error in your suspension setup.

i always had about 15-20 in bags also and started with 20 in tires but usually ended about 16-18

Thanks guys

those tires are very sticky, so you probably won't need to at the track, but you can safely drop drag radials down to about 12 psi, just air them back up before you head home. I know several people who will drop them to the single digits without issues, but i wouldn't.

lol...single digits...

**** just let all the air out...

I tought it was too much sidewall to lower the psi too low. I can't ever really get this tires too hook right.

I've recently changed from Mickey Thompson 265/40/18's to M&H 275/45/18's and am amazed at how much easier the car is to drive as I'm no longer fighting the steering wheel trying to keep the car straight as it launches.
The increased diameter is effectively changing my 4.1:1 diff gears back to about 3.7:1 which may be a big part of the reason that it a lot less violent off the line, yet is still running 1.5xx sixty foot times.

A side benefit is that that take a lot less time and speed in the burnouts to heat up.
