    what to expect

    what kind of HP gains can i expect from these Mods...my goal is to get to about 350 to the wheels this winter.

    -Pacesetter LT's
    -SLP II Cat back
    -BBK 90mm intake and TB
    -SLP Lid(the K&N Filter and Fernco)
    -dyno tune


    It already has 4.10's..i was told that adds HP to wheels, true?

    Gears don't add HP to anything. They do make you accelerate faster though.

    Steeper gears actually read lower on a dyno.

    not enough for you to care, if you have an m6 you should be low 350's it will be interesting to see if that big manifold and throttle body did with your stock heads.

    It is a small percentage. Not that it matters...it would be faster.

    I will say you will make right at 350RWHP even with the 4.10's.

    I couldn't get the fernco to fit properly around the bottom of the maf - it doesn't bend enough. How did you get it to fit?

    I had little problem with my 4" to 3" Fernco.
    Microwave worked well to soften it up.

    If it's a Dynojet I'd say 340-350.
