1986 turbo 5.3 trans am at lebanon valley dragway 11.52 at 122.5 mph
Gopro vid of me making a pass at lebanon valley dragstrip. Trying out the new 2 step, and had it set to 3700 rpm this pass. Car hooked great and ended up getting a 1.85 60 ft. this pass. Gotta get a bit more practice and find the sweet spot with it! For some reason, my mph has been all over the place. Need to get that sorted out as well.





Turbo 5.3 LM7 1986 Pontiac Trans Am 3rd gen at 5 PSI - 75-135 mph pull starting in 4th gear
Engine is a basic stock bottom end 5.3 with 6.0 (317) heads, LS6 cam and intake, and turbonetics 76mm BB turbo. Started low in 4th gear from 75 mph and let off at 135 mph. Car has A LOT left in it since the turbo is not even close to it's efficiency range yet!
