I ran 18 lbs in the Nittos and 15 lbs on bfg's on my 93 vette. I have noticed that the same tire sometimes needs a different amounts of air on diferent cars of the same model. Start high and lower it until the wheel spin is gone. trial and error my friend, but I hope this gets you started. Oh yeah and on the nitto's get them good and hot on your first pass and then after that just get a little smoke and you should be good.
Thanks for the info. I'm taking it to the track tomorrow, so we'll see how it does. It'll be the first time I've run it with the blower. We'll see what kind of numbers it puts up. Thanks for the response.
