lol... i havent run it at the track, but i would say it runs a low 13/high 12, but then you will just say that without vid's or slips, im just guessing. then i would say that i make 220whp/205wtq @ 7psi in a 2200lb car, but then you would say that without a dyno sheet, you dont believe me.
so that is why i say 17's @ 75mph.

edit: and before you try and say that even 13s/12s isnt fast, a. i never said i was fast, i just said i wasnt slow and b. i am only running on my waste gate spring and can always turn up the boost. my current setup is good for a reliable 350whp. i can pm you info on my complete setup if you want, but then you might just think im making it all up.
