    Forced induction Dyno proven hp and engine modification thread

    Post up your Dyno sheet of your Forced induction pulsar

    Please post as much info as possible, such as:

    Engine type
    Turbo
    Boost pressure
    Injectors
    Ecu
    Cams/ headwork
    Compression
    Exhaust /Intake
    Anything else that you believe is responsible for helping you achieve the power level you have

    Please also note if it was done on a hub dyno

    My old setup:
    GTiR motor in FWD
    hub dyno (therefore torque is actually accurate, but this dyno is known to pull a bit more than other local roller dynos)




    high boost at around 18psi, low at 13psi I think.

    gt2871r
    Tomei 260 degree cams, 11mm lift (no adjustable cam gears)
    CP pistons (actual comp ratio probably around 8.8:1)
    Stock rods
    Supertech springs
    ID1000 injectors
    Stock intake and exhaust manifolds, 3.5" dump pipe, 3" straight-through exhaust (magnaflow muffler, no cat)
    No porting or matching
    Z32 AFM, PowerFC ECU, Crane LX91 ignition coil
    Walbro 255 fuel pump, SARD fuel pressure reg, 98 RON

    The motor died very soon after that from a number of internal failures, but no sign of damage from fuel/ignition/tune.

    Ignore the green tune, it valve floated with cheap valve springs

    Red tune is current, it pulls timing to tell you to change gears, the less load, the more it pulls timing, hence funny last 1000rpm

    gee thats big numbers. how is the T51 not choking to death? I know they like a bit of a boost, but surely 400hp FWD would flow too much for it? (though it does look to take a while to spool in the graph)

    The T518z is absolutely maxed at the boost it's at,
    I am yet to find anyone who has pulled these number on this same turbo,
    Also, when I melted my last motor I melted the turbine wheel with it, so I bought a TD05 18g rear wheel and while I was at it I bought a Kinugawa TD05 18g anti surge cover for the front of it,
    So I can say with 100% certainty that it's not high flowed or tampered with as these fitted perfectly snug,

    It looks like it takes ages to spool/come onto power but it's on a fairly low ramp rate on the Dyno, without the load it's looks very delayed, on the street I see boost much earlier,
    (This is also why you see the soft limiter coming in)
    Also I run massive overlap, an extra 10 degrees I've dialled in with the cam gears, and yes, you heard right, overlap on a turbo motor,

    On 7psi I make 260whp
    The car/ turbo always seems to make 10hp for every pound of boost, take that into account and I am literally making 190whp on the motor alone!
    I also have am astonishingly good tuner and I have my little secrets as to why it makes the numbers it does (;

    And another thing, if you check out my car in the Garage section you will see a 130mph quarter mile pass I did to back up the power figures
