    • Gintani sets new E9X M3 S65 V8 horsepower record hitting 828 horsepower with a Stage III supercharger

      Things are progressing nicely on the M3 front with Gintani recently recording 828 horsepower at the crank in a manual E90 M3. The car has a low compression built motor (compression will not be revealed at this time) and hit 16.5 psi of boost from a Vortech YSI. The blower has more in it and could likely be overspun to the 22 psi range but for now 828 horsepower at 16.5 psi is very impressive and more than anyone has made up until today. Expect to see more out of these Stage III cars, like BimmerBoost's own project M3, in the next few weeks.

        These are massive numbers.

        And... dynojet reads higher than dyno dynamics consistently.

        It does not matter anyway, it's all comparative as a GAIN over stock.

        We have never seen anything over 645 flywheel in Shoot 8F on our dyno. We know other supercharger setups in the same mode make around 600-630 in shoot 8F with a correction factor of around 1.00.

        Nice when people understand what the numbers mean.

        Built internals, yes.

        I believe so but can't guarantee it. It won't be as fast as my car but is still going to be very strong.

        Cool, should be a good measuring stick then.

        Your car is going to be there as well, but should be faster than this one?

        Not sure what you are asking? My car will not be there. Visited it today though, a lot of work and some challenges ahead.

        i would hope built with a YSI!

        im gonna guess 670rw on a dynojet at that boost level.... maybe 680 if the tune flirts with 17psi on occasion.

        anyway, who cares....this is going to be a blast to drive....gintani is making turbo power out of a blower!

        i can't wait to see what that south african s65 turbo will do!

        It's going to be in the 700's on a dynojet with a manual easy.

        There is more in it too... I'm excited about the prospects Click here to enlarge I'm going to do my best to hit the 800's. That whp with a DCT is going to eat the other E92 M3 setups out there alive.

        Saw the car today and talked with Alex a bit. This is going to be fun based on what is being done with Brian's E90 M3 which is the car this thread is based on. I can't wait.

        i doubt a stock tranny will hold more than 82% thru the peak torque rev range.

        btw sticky - think your SSP goodies will reduce drive train loss percentages?
        itll be interesting to see yours once you have a flywheel/rearwheel graph to compare to stock tranny gintani SC's

        No, I don't expect drivetrain losses will change much at all. Think of it as the equivalent of a stronger clutch in an SMG car except I'm doing it with two clutches.

        Stock DCT tranny? I guess, not applicable here though. Doubt anyone would do a Stage III with a stock tranny.

        wait... this M3's 6mt was massaged by SSP as well? or just an upgraded clutch?

        lol, i had to rethink what i said. i dunno how i thought a built tranny would help drive train loss...been a long weekend i guess.

        did you go with the CR that the stage 3s have or are you doing a custom CR?

        Sorry, I was just referring to my trans.

        This would have the Gintani clutch upgrade I would think.

        Um, I don't think all the built motors have the same compression.
