never ran my car at a 1/4 mile strip but in the 1/8 i run 9.0. that's with the mods in my sig, no cat, and the bottom honeycomb removed in the MAS. and i've heard of people running flat 13's on the stock turbo and you can't push a stock turbo much over 15PSI. i've also been told if you add 4 seconds to what you run in the 1/8 you should have a pretty good idea off what you'll run in the 1/4. so with what if that is true i'd run somewhere around a flat 13 so i don't think you should have to big a problem getting in the 12's if you know how to launch and drive <--that right there has alot to do with it!

but like remy was saying if you've never ran at the track before don't expect too good of a time.
