Ok thanks guys. I think I'll start at 14psi and go down from there. I think my car will hook since it does on DR's. I just want less rolling resistance on the top end. Hopefully I can get some 1.5's w/ the measly power I'm making. I used to do a John Force style burnout w/ my BFG's but I heard for slicks you don't really need to smoke them that bad do you? -Mark

It really comes down to what works best for your car, you just have to experiment.

To do it properly, use a tread depth Micrometer and keep track til you get a pressure that results in a full contact of tire surface.

Tread depth? We are talking about slicks here. You are right about looking for complete contact though. Assuming the rims are the right width for the tire (meaning the rims themselves don't cause the tire to bow out) you can check this by getting the tires wet and driving them a short distance on dry pavement (I've done it in the driveway) start high and slowly get the air pressure to where the complete width of the tire leaves a mark, use that as a starting point at the track. Every car is going to be different because of weight, but if you are running a 26" x 10" on a 7" wheel, you will never get the entire tire to touch without running it flat.

If you get a chance, try what I said with the water on smooth pavement, it should give you a good starting point. Sorry I didn't say it earlier, I was caught off guard by the 10 psi comment

The best bite after a burnout is the next one so that is when you do not dry hop. When the tires are not heated you dry hop them once to knock off the sand and go. Only have been down the track at least 500 times or so.
So check yourself with the comments.
Mark run 14-13 pounds and see how it goes from there. If it hooks good then bump up another 1/2 pound until it starts to spin. And remember Mustangs like a little spin so that is something to think about too.
Make sure to get a very good tire pressure gauge and keep the tires out of direct sunlight if possible. Also know the on the first run you might want to start with one less pound than what you intend to run becuase they are going to gain a pound after the first burnout.

I would say alway do a water burn out with slicks, it doesn't have to be a John Force style smoke show, but it's easier on your drivetrain than a dry hop, and you'll know for sure your tires are clean and warm, just stay away from the dirt Scott just put down
