...I have a TT stage III with gutted pre-cats and just ran a 13.4 quarter mile with stock 16" Dunlop SP8000 tires. However, a friend had a stock 1999 C5 Vette that ran 14.1's straight. If it has 345hp and my TT has 420, why would he be slower other than being a bad driver. Could it be gearing or just sheer power? Mind you his car is at least 600-800lbs lighter. I also heard that my TT can be in the mid 12's with a pro driver and a slick tire. BTW-What other mods should I go for next? What is your best time with a TT?
