    Opinions: ASCO Plenum

    Just ordered the Z31 plenum from Zack at ASCO and am anxiously awaiting it's arrival and more impotantly, the installation. Would like to hear from others who have completed this mod about HP gains and/or any other gains. Thanks

    Probably won't notice much without other accompanying mods.

    I didn't list my current mods as thety are listed in the sig.

    1) K&N cone Filter
    2) C&M Performance 3" with hi flo catalytic converter and muffler
    3 Turbosmart MBC set at 10psi currently (will probably turn that up to 11 or 12 psi when the plenum is installed. Prob stick to 11 till I get an intercooler installed.)

    Have gotten the plenum installed and will pick up the car on Wed. My mechanis indicates significant increase in mid-hi rpm response. It appears to be as advertised by Zack as it relates to HP gains and response.

    I'll add more to the post after picking the car up.

    I've never ran a stock manifold and gutted to compare, but by design (greater volume), the gains should be in the mid-hi rpm range.

    MMHMM, but stock is better for low-mid.

    The plenum is in. Bang for the buck is low. The claimed 7-10% increase in hp I believe is mildy overstated. Still good.

    Should have gone intercooler first. Oh well, live and learn.

    I didn't go to a gutted plenum until I got my 6765 turbo.

    I even had a t3/t04e pushing 20+psi, and I was still using the stock oem plenum with the stock throttle body.

    You really have to have supporting mods to utilize the potential from a gutted plenum, even then, you may not "feel" the difference.

    At what level would this make a significant difference or would it? Zack indicated it would bring 7-10% based on the mods I have currently. I guess we all have to make a buck.

    For starters, ICing, safe boosting (stock t3 = 12psi max).
    Intake, exhaust, the basic stuff.

    If you get Nistune, bigger injectors, and a bigger turbo, you'd be doing well.

    You can't just expect to slap it on and gain that 7%-10% gain without a tune.
