RE: Scary dyno torque numbers???
I'm not putting the torquenumbers in my sig because I'm not sure why they are so high, although they appear legit and reproduceable (3 runs). Going to call transmission and turbo people tomorrow to get some more feedback...help me understand better the relationship between the turbo and the race transmision.
Might go to the track if we ever get a cold front through here and clean out the muggies. My mechanic will do some test runs...maybe slip on the MTs and just practice with the transbrake...Not 100% sure, car can finish 1/4 with gearing anyway... Engine rebuild (later this month) will include cam work to get at least 7000 rpms. Last season with just Procharger (everything else stock), cargot into high 11s. Our goal this season is high 10s????? Next season going to shorten rear axle and tub it.
Go run that SOB at the track and see what your times are

RE: Scary dyno torque numbers???
First off, I still dont understand your 600+ Rwhq, not sure if i caught your rwhp? something does not add up, even if its not the dyno, something is wrong. Trust me I LOVE TURBO's, mine has sick TQ but I doubt you have that much more than me with only 1 more LBS of boost.I know one thing if that's an accurate number, i would be REAL careful until a motor build.
If you really have 600+ twhq, then you should be over 525 rwhp, which means you should be high 10's of you were in the 11's.
Either way got the track, thats the best and true test of a dyno/

RE: Scary dyno torque numbers???
I agree that probably something is off. I'm looking at the dyno sheet. Will take a pic and send it to both turbo and transmission people. Looks like the MAFia pegged out at about 3500 (which was bad)at which time the rwhp was 431 (where would have rwhp been at 4500, 5000, or 6500 rpm?????). The rwtqreached 656 at 2900 rpm which is about where this turbo is supposed to peak. This was the third run showingvery similarresults.
More I think about it, doesn't seem to be any point in taking carto the track until the MAF is sorted out. I could always have it dynoed somewhere elsejust for a comparison. Still think it's something to do with tranny multiplying the torque.Maybe will have answer tomorrow from the experts.
