Wish me luck! I just put on Drag Radials for the first time I've always run a slick. I went with the 315's, they are a really tight fit. (30" tall!) I need to start testing with them so I can run in the Holley LS Fest. Between the new boost controller and tires I'm going to have my work cut out for me. Those guys are running so fast in that class, I'm in serious trouble! lol Wish me luck!
I'll post up some pics of the tires on the car.

Waiting for shocks.

That's a really big tire. Most DR classes are limited to 275/60/15. We are looking to cut some 1.2's tomorrow on the Hoosiers with Steve's car. I know they are running 1.1's with them. Don't be surprised if the car cuts stronger 60's than it did with the slicks. They like the pressure between 17-19 psi usually. We have the most luck on the high side.

We have QA1-R's up front and AFCO's in the rear of Steve's car. He's got a BMR drag bar, BMR LCA's and stock springs all the way around. The rear shocks are set all the way tight and the front are 2 clicks from tightest usually. Drag bar has 1/8" preload with the driver in the car and the front tires off the ground even. Pinion angle is -2. LCA's are just about level with the horizon. If the track is not well prep'd, we start by going to about 6 clicks in the front and start loosening the rear 2 clicks on the squat.

Hmmm, sounds like you're unloading after the hit. What is the suspension setup and how is it set?

One problem is that my old boost controller was fubar! I coundn't control boost. I was leaving at 3400rpm @ 3lbs of boost. When the boost came in the **** would hit the fan. lol

Yes that's what's happening. I'm waiting for my shocks and new suspension tune up in the mail.
