    M Coupe TT GT35R Done...

    For those of you that may not be following on bimmerforums...

    My TT stage 2 35R car is done...

    Dyno below from Max PSI autodyne superflow 30, which reads a decent amount lower than a dynojet.

    Gotta figure out boost a little bit, ams-500 should be a FLAT curve, not tapering. Mike feels it was the dyno being in inertia mode, so we will try again in load mode sometime soon eventually.

    14.5psi max boost, tapers to 12.5 by redline.
    SAE numbers: Max tq was 398 at 4800 at 14.5psi max hp was 430 at 6250 @ 13psi

    For comparison: Mike said he would expect car to be between 450-460 on a dynojet. A recent TRM car just finished at Max recently just ran 440 on a dynojet, and made 407 on max psi autodyne; so the coupe is definitely running strong!!!

    3" downpipe to a center magnaflow that is single 3" in dual 2.5" out to my two rear 2.5" input magnaflows. Gotta keep the twin exhaust on the coupe, it would be almost sacreligious otherwise!

    I agree, but you should think about adding a cutout. That would tq curve would hit a little harder.

    Was thinkin about it... but honestly at 14-15psi, what I have is plenty for what I will be using the car for.

    Not to mention I have the exact exhaust setup as Rukman, and he picked up ZERO hp when he ran open downpipe on the dyno, so it is definitely not a problem of exhaust flow or backpressure by any means. Tq hits harder on the street as well and it spools way earlier, kinda just like my boost doesn't drop on the street either.... dyno'd aren't always the best comparison.... the 1/4 traps will tell me best what the car is capable of once I can eventually get there.

    Tough bc since I work in NY and I get home at like 6:30-7 every night, so by time I change and drive to the track it's going to be late, so it will be hard to get some runs unless I get to a rental or something one day eventually.....

    60-130 VBox runs coming up this weekend though most likely if the weather holds out. So at least I can use that as a point of comparison to some other cars I know times of.

    Nice chart, what is the curb weight on the car? Seen a few at the AutoX and they look very sturdy.

    About on par and equal for mustang numbers from what I believe...

    I will get to a dynojet soon just for apples to apples comparison, since that is what everyone really refers to for numbers unless its dyno dynamics in shootout... but even though the majority like to see dynojet #'s bc they are so inflated. I don't really care either way, I was never really a numbers guy.
