Awesome results with a track and temps that COLD
. I use to find at Raceway Park, as the temps went down, so did the track GRIP. Wish I could still have my 1989 TTA that ran a best of 12.18 @ 115 mph. I had a K & N filter, hollowed out cat, Flowmaster muffler, reworked turbo, BFG Drag Radials and manual boost control set on 20 psi. All this out of a stock tune from a 3.6 litre V/6. I figured that it was putting out around 450 hp to move that weight down the track.
If GM had continued with the development of that turbo motor, who knows where it might have gone to and still get 28 mpg.
