Maybe i am wrong, but all TTA's were Turbo'd AND RARE! Why would someone take a potent motor with a turbo and change it to S/C? You sure it wasnt just a T/A with a S/C and a V8? That dude would make more power by keeping the turbo rather than switching. How often do you see these TTA's? No flame, just a question.

I think you misunderstood me. I had the V2 S-trim on my 99 GT when I raced an 89 TTA at a GM vs Ford event on Long Island in Oct.00. I realize they are rare and I haven't seen another one since. My friend videotaped the pass and I would love to put it on the computer. I believe only 1,550 were sold to the public and stock they ran something like just over 16 psi. I also agree about locking the converter in 2nd. My chip locks my PI multi-disc in 2nd and now my car runs 120-121 mph trapspeeds with only 12 psi. With the Protorque locking at the top of 3rd, my car ran 122-123 with 16 psi, but 100-101 mph 1/8th.
