    Latest Dyno Run.......

    We are getting closer with the torque numbers. The hp dropped a little but the torque is way up. I believe this is due to the rain and higher humidy in the air lately. The car still needs air/fuel adjustments between the 3900 and 5900 rpm range. It is still running too rich in this area.

    RPM's--RWHP--RWT
    2600--138.7---280.2
    2700--154.3---299.8
    2800--166.9---313.0

    Re: Latest Dyno Run.......

    Hi Chad, I'm getting warmer to the idea of a power trip myself.
    I just compared your last horse power chart to the Evo stage
    4 package, and it seems about the same all the way across.

    http://www.evoms.com/p996tt%20stage%204%20hp%20dyno.htm

    I only plotted between 2500 rpm and 6000 rpm, but if you are
    running rich above 3900, you have some room to grow.

    What gasoline are you using? thanks,
    Joe

    Re: Latest Dyno Run.......

    Hi Joe,

    I wish EVO would show their torque numbers. Do you know what their torque numbers are? At 3500 rpm's it appears my motor is producing about 65 more rwhp. At 4000, 5000 and 5500 the two motors are about equal. My dyno sheet is actually at ten rpm intervals and it is a smooth curve all the way up. No sharp jumps like the EVO graph. In the next two weeks my graph between 3900 and 5600 should improve once the air/fuel mixture is corrected. Time will tell. After the 5500 rpm range my motor gains another 50-60 rear wheel hp over the EVOMS Stage IV motor. In addition my motor is still very close to producing peak EVOMS Stage IV power to 7100 rpm's. Bare in mind, we lost about 25-30 hp across the board due to high humidy test conditions. The previous run produced 614+ hp, but produced about 50 less pounds of torque. In that run we were rich from the 3000 thru 5700 rpm range.

    Re: Latest Dyno Run.......

    Good enough. I do look forward to your next runs.
    If you plot your horsepower to theirs, it's similar (just
    your last imperfect run). Horsepower and torque are
    mathematically locked in sync. Horsepower is a linear
    product of torque * RPM, so if your car produces
    XXX hp at YYYY rpm, and another car produces the
    same, then the two cars are necessarily delivering the
    exact same torque. HP = torque * RPM, so if you have
    any two, you can get the third. Just get the units in
    sync. Ie: 1 hp = 550 ft lbs/sec. torque is in ft. lbs,
    and RPM should be divided by 60 to get you /sec.
    Joe

    What gas are you running?

    And what gas are you using? Is it California pump premium,
    or better? thanks,
    joe

    Re: What gas are you running?

    Joe, the above numbers were obtained with a majority of 100 octane in the tank (80+%), the balance being 91. In low boost on the car (1.1 bar max.) 91 octane is used. In high boost (1.3 bar max.) 100 octane is used.

    The car is equip'ed with an adaptive boost controller.
