First off, thanks everyone! And people should look at the 29whp, 80wtq delta to see the evidence that meth should be a requirement for these cars!
No worries my friend, another time! Quote:
Thanks! I was quite pleased with the logs, the timing looked perfect! Quote:

SAE best numbers were 420whp, 458wtq. SAE assumes 77 deg F, 29.234 in-Hg, 0% humidity, STD assumes 60 deg F, 29.92 in-Hg, 0% humidity. So when you consider the conditions of my runs (around 67 degrees, 30.15 in-Hg, 22% humidity as recorded by the dyno), my car made better power uncorrected in less favorable conditions than those as prescribed in STD. So frankly, if the car had actually been run in the STD conditions, the numbers probably would've been higher.

18-19 PSI is actually a sneeze at these low RPM's. If you look at the efficiency graphs VS RPM one can see these turbo's are more then capable of handling the boost in the mid-range.

Only +29WHP. Sometimes we see meth only to be worth +29WHP. Is it the stock turbine wheel that becomes almost an absolute limitation at these levels, so that meth + FMIC + more advance do not net more than 29WHP? Do you have catless DPs, stock catback and DCI?
Good torque btw. As others have said, it is fine to run that much boost at mid range. This mapping is nice for a daily driver, since you have the power handy independent of the revs. |

And honestly, yeah, I think the turbos are pretty tapped out by the time HP comes into effect...I mean look at how much extra power I made by going up a half a pound of boost and adding a bit of race gas...I got 2 whp, 5wtq extra. If you look at the graph, you can see the extra wtq gained from that extra half pound of boost from 3,000-4,000 RPM; from 4,000-4,500 RPM, it's still apparent, but less so, and by 5,000 RPM, the difference has pretty much disappeared, well before the point at which peak WHP will be made. When you see that, it becomes a bit more apparent that the turbos are simply out of air at the WHP point. ![]()

Yeah....those earlier AFRs do look kind of scary compared to the newer ones. Hoping that's not the case for the older 12-17 maps on rev2 since the rev2.5 hardware change does allow you to run richer AFRs...
Defacto, What maps were you running anyway a year earlier? It's wierd cause some Dyno graphs I've seen richer than stock AFRs on the 12-17 maps and then yours? Maybe the probe was placed in the wrong spot during the run. I just want some peace of mind.... |

So... what's the power say on 90 degree weather or overall any kind of weather day to day driving. Say the day after you did these runs was 90 degrees, how much power would that be?

Thanks Zach! With winter break coming up soon, you gotta get yourself on the dyno, I'm curious to see what you'll make!

Definitely! Both sound good to me, let me know how long you are in town for. With the similarity of our mods, I'll be very curious to see what you put down...it'll be tuner wars...in real life! :P

Your car is beastmode!!!! Great numbers. Yea it looks like you have hit the limit of the stock turbos. I too would be interested in 60-130's.
