    i would say with a good tune at least 430 to the wheels. you will definatley make over 400 to the wheels and over 450 flywheel horsepower

    I have an A4 which is why I only wanted 3.73's.
    I'm getting a Vig. 3600 stall and trans cooler as well.
    I'm running stock heads (241's)...
    I'd be happy breakin the 400 mark I guess.

    They told me the 383 stroker kit should give me about 50lbs of troque & I think they said 50hp.

    Well I have a M6 but I have a stock 346 with stock heads and that cam with 4.30 gears. I wish I would have went with 4.56's. It doesn't start pulling hard until about 4200.

    I'm sure the stall will help. You think an LS6 intake w/ an 85mm TB is gonna choke it or should I go for a Fast 90/90 setup?

    I disagree. Well....maybe a 3.90.
    4.10 would be too much even spinning to 6600RPM's. 122MPH would be top speed in the 1/4 mile. Most likely go faster than that. Which can be fixed with either a taller tire or less gear.

    Awesome! I could live w/ that. Especially cause I'm strapping on a bottle as well. I'm already lookin for taller & wider wheel & tire packages man. Thanks!

    Sadly now demodded :(

    With a well prepped engine and good tune and a few supporting mods you should be able to do approx 1hp/cid. More/better supporting mods (i.e., TD's) along with heads/cam will be even higher.

    For example, my 02 with CAI, LT's, ORY and cutout put down 343rwhp/357rwt with a good tune.

    In the next couple of months I will go back on the dyno as I've add TD's to my setup. I'll also be going to the track in the next couple of weeks as I've added 3.73 gears and an adjustable TA to the mix.

    thats a pretty good setup because the trex is such a radical cam... but the 383 can handle it since it has more displacement. i guess around 470 to the wheels depending on what kind of kit it is... etc...
