    I'm intending on doing a 3.25" pulley build (on a ported gen III) with the Intense S1X cam, AL104s, SD Headers, 180* thermo, custom intake, and a dyno tune.

    About what times should I be looking at with this setup on a good day, possibly with a set of slicks?

    What's the DA and Altitude of the track?
    How good are you at launchng?
    Do you have KR?
    What fuel are you using?
    What is your AFR at WOT?
    What's your race weight?
    How well setup is the weight distribution?

    There are too many factors to give a good estimate.

    I'd say mid to basement 13s, but why bench race when you can get a timeslip?

    assuming you have a good tune and are in a pre-gen, then you should be high 12's/basement 13's.

    That's a 13 second car all day. Throw some nitrous and you will hit 12's.

    Get a few hundred pounds out and I'm sure you could pull high 12s...depending on other variables that spade listed

    Dyno tunes are lame.

    Get a wideband and have it tuned on the street.

    Make sure the transmission is in decent shape or that'll be on your list of stuff after taking it down the 1320. I ran basement 13's with a XP, headers, 3.4", and a DHP PCM with some wide ass Cobra wheels/DR's. I think 305's LOL. My trans held fine but it was also a newer car at the time, only a few years old with 60~k on it.

    I'd bet if it's a cold day and you pull a sub 1.9 60 ft...I don't see why 12's couldn't happen.
