I have wound mine out to 120plus with 3.40s and 26 inch tall tire. Starts shaking a bit past that I run very similar times as mavaholic best is 12.90 at 106mph with 1.8 60 ft time. I have never dynoed it but i figured on 275 to 310 rear wheel horse power. My car with my 195lbs carcass wiegh in at 3100lbs. I believe Rick Porters "street car" runs about the same too. I had a blast racing them at the round up.
