*ahem*
One last time.........dead damn stock '07 GT automatic with 17K miles on it. Even down to the 3.31 gears. Hell...it even had the factory cat-back system on it. Completely as it was delivered off the lot at the dealership. After the first outing we added a PI converter that was supposed to have 3200 rpm stall speed. It had 2400. The car still wouldn't spool the turbos for 60 feet. Turbos spooled at 2700 rpm and had a full 8 psi at 3500 rpm. Now...had I been able to leave at even 3000 rpm and let's say roughly 4 psi of boost the car would have run 10.60's at 129-130.
Now....add a set of 3.73 gears and you have a 10.30/132 mph car. Turn the boost up on the turbos with good rods and pistons and who the fuck knows how fast it would have run. My calculations show that with a stock bore/stroke engine, 3000 rpm leave, 3.73 gears and 14 psi the car runs 9.60-65/140-142 mph.
