    Results of GTX rebuild by Nils

    Since I am still breaking it in, the WOT's were limited but here are the results:


    Full tank of gas
    Air/Water 80
    1st run 73.8 @ 8450/8500
    2nd run 74.8 @ 8450/8500
    3rd run 75.4 @ 8500 (5 bars of fuel)
    4th run 75.2 @ 8500 (5 bars of fuel)

    So, for now, looks like a rock solid 75 +++ with a lot of gas....

    I might have a boost gauge problem though because I am still pegged at 11 pounds, the exact same before the rebuild. This is not an indication of a leak problem....

    Jay,
    those are promising results but whats up with your boost? Nils didn`t forget to fit your overdrive gears did he . Did you remove your flame arrester in the end? Wondering if you might have a leak there.With those revs you should have 13lbs easy unless Nils has done the best ever valve and port job.Oh yeah,the sweepstakes not won till your all run in and have found that boost

    I wish I knew and have no idea unless the gauge is defective

    Yep, I removed that while waiting for the motor

    I've checked for leaks but a leak happening at the 11 mark would seem a little odd..

    Oh yeah,the sweepstakes not won till your all run in and have found that boost

    Jay - 4" intake all the way to the mouth of the s/c? BTW - I have never seen 13 lbs. 12.5 consistent @ 8500-8550.

    Brendan,

    I am running a modified rear intake set up. Basically, I am only running about 24" of 4" hose from the supercharger to the air intake. About the only way to improve that would be to stick an air filter directly on to the supercharger.... I am starting to wonder if maybe my housing was bored out a little more than others so the tolerance is greater from the impeller to the housing??? I should be seeing a bare minimum of 12 lbs with my current setup...
