203.73hp and 195.31 lb-ft of torque. I was hoping for more- but the car is totally stock and I think my car is already doing pretty well on the spectrum of stock Dynojet graphs I've seen. Water pump is failing so it could be sapping .5hp or so, Dr. Vanos was done which may or may not make any difference in the torque curve, and my DISA dip is quite subtle.
I kind of ignore other random dynos when I see the results... no way to compare.
I put the results at the end of the video, failed incentive I guess...
I must be missing something, over 200 HP on a stock ZHP? How'd you get that?
Thought they were 235 stock when new... Is that number not at the wheels?

Duh. Not sure what I was thinking (maybe 307). My bad.
That's at the crankQuote:

Solid numbers for a Stock ZHP, Derek. I watched all the Dyno runs and just exited cause I didn't think there would be anything else LOL.
Also keep I mind its a estimate from BMW, each engine made will read a touch high or low. I suspect zhp's read higher in general, I feel like there has to be something that limits drivetrain loss closer to 10% than most estimate around 15%. Who knows though.

My hypothesis is that how your car dynos has a small amount to do with factory variation- and a very large amount to do with maintenance and going the extra mile in that regard. I really like the shop, so as I make changes I'll dyno it pretty frequently. I have a few power tricks up my sleeve too. :)N
FWIW the E46 M3 guys think the drivetrain loss correction is more like .82, because lots of E46 Ms dyno around 275rwhp stock.
In that case I've got like 250 at the crank, and I don't think that's correct. :dunno
My car also must have had the software update based on the DISA dip, do you guys concur?
Your blue looks :drool. Probably not what I was supposed to get out of that video.Quote:
