I just converted my 97 formula from a T56 to a built TH350 with a Art Carr 3800 stall. The car has full BMR adjustable suspension and QA1 coilovers front and rear, with a strange 12 bolt with 3.73 gears.

My best pass with the T56 was 12.60 @ 114 with a 2.01 60' what should I run with the TH350? I also have nitto 555r DR. Engine is in my sig!

At 109 I was in the 11's if MPH is an example of horsepower. Sounds to me like your issue is traction. I was getting 1.6 sixty foot times back then.

The whole reason I am installing the th350 is to make the car more consistent and solve the traction issues.

The t56 tranny is not to blame for the poor 60ft. My stock engine with exhaust manifolds produced a consistent 1.83 60ft. 12 bolt w/3.73 gears thru a t56 on slicks. The DR with a t56 is very tough make work consistent. You probably could get good time improvement with the auto, but it's not because the t56 was wrong.

I know that the t56 was not the problem, it was just too inconsistent. The DR's were the issue, the car is really just a track car so manuals are not the route to do for drag racing.
