    Default 13.66 basically stock 87 turbo. 8.5 psi

    My friend ran his 7m supra at the track.

    Well it has
    exhaust (stock elbow)
    a fully built shortblock
    2.75 inch pipe where the 3000 pipe goes.
    8.5psi (stock waste gate)
    245 tires.

    best time was 13.66 at 104 mph with 2.25 60'
    best mph was 107

    Engine build specs
    http://www.supramania.com/forums/sho...07649-7m-build
    9.3:1 CR
    2:0 MHG
    cams gears on stock settings
    AEM is not on the car yet its on stock ecu.
    All the mods are listed
    I dont think the built engine helps where everything else is stock.
    Tires are kumho 225's
    91 octane
    1200 foot elevation
    track temp was around 65F
    Timing is 10 degrees(base)

    This is a stock baseline before tunes it with cams and big turbo.

    So your on a stock CT26 compressor wheel at 8.5 PSI right?

    Not to come off as an Ass or anything but your build is FAR from "stock" you have a fully forged bottom end, 5 angle valve job, higher compression ratio than a N/A 7M (9.1:1) and stock turbo 7M is (8.4:1) That is a BIG difference..

    Im not sure what the CR is with the 2.0 gasket. Pistons are rated with a 1.4 gasket.

    Stock wastegate so its like 8.5-9 psi.
    Turbo is stock.

    You are correct. Far from stock.

    Of course it does. It has higher comp and it also has head work. No stock MKIII traps at 103-104 or a best of 107, THAT'S a FACT.
