 I agree with Steve on this one.


Besides Brad uses front wheel drive slicks so he has to put them on the front.

Yes...your RPM's will be lower with a taller tire.

 Each 1 in of tire height = approx 300 rpm at the stripe so 600 rpm lower.

The question is where do you get an 8" wheel with 4" backspacing

Summit has a pretty good filtering system on their website. Just select everything that you want in a wheel and it shows what they can get. A phone call to confirm wouldn't hurt. Here's a link with all the filters in place. I hope it works.

Ran 12.6 - 12.8 all day. Won 6 rounds of bracket to take first plact trophy. Ill post a couple slips tommorrow. Best 60ft was 1.88 with a finish of 12.638 at 105.17mph. Need some tires if I hope to get an 11 slip :) my tune had SM recall 782 at 104 with 0 knock running 24 lbs off the line creeping to 25 by finishline. Couldnt leave with any boost. Tried one launch at 2 lbs and blew away tires. Great time today. Buddys mustang ran 11.5 all day.

I'm guessing you let off toward the end. 105 isn't much mph for 12.60s. Should be in the 107-108 range. Though with a 1.88 60' it comes on strong to get to the 12.60s

Looks to me that you have the big end tuned pretty close.  No PL log?

With that 1.88 and ramping all the way up to 12.6 I would say he is at 78-79 in the eighth and it comes strong on the top end . Just a guess.

With that alcohol it needs more boost and might need a larger injector but more tuning and traction definitely.

Post us a time slip Shimy. And keep up the good work.
