Got the car running again last week after a lot of help from Brian, Jim and Brad. It had been down on power last year from a mystery problem and got pulled apart to try to fix it, put in a new clutch and fix reverse. Goal was to to make it to the Midway Shootout at Cedar Falls and have some fun. The car had previously made a best 492awhp with normal correction on my dyno with the boost maxed as high as I could get it to go. The power band looked pretty bad with the way the boost dropped and seemed to be getting choked. With it that way my wife went 11.5@132mph not using NLTS and it falling on it's face going into 2nd gear every run.
We ended up taking about 100lbs off of the car between the slicks, removing power steering, lightweight front crossmember from Halon and a few other little things. With the weight reduction, slicks, NLTS and me driving I thought it might run into the 10s even if the power ended up being the same. We changed a few things in the setup powerwise, but still the same old SC61. After fighting some leaks after startup and then a locked up rear caliper on the dyno it was making good power with a really nice powerband. I turned the boost up another psi and was going to stop after the next run due to the factory internals but the tranny let go instead.
Dyno chart is a comparision of the old horsepower/boost versus the run before the tranny let go.
