may i just add that harolds maxima is on a STOCK motor, stock internals, stock transmission, stock suspension, stock axles...basically stock everything besides the turbo kit and an upgraded clutch and injectors. I helped him tune it last week on his emanage with a rich low 11ish:1 air/fuel mix. And it still holds up on 6 grand clutch dumps on slicks.

He ran it at the track last week and only got in 3 runs, but his best run was a 12.2 @ 123.
PS. Btw, its 538 whp, 603 wtq. Scott mistold me. But still impressive nevertheless.
