lowered static compression sucks at 12psi:

but at 15 (actually 13 and up) the glory of MBT of timing comes through from 4000-redline, and the #'s jump dramatically:

advancing timing at 15psi did no good, lol.
my uneducated, misinformed theory:
The gt2860rs "works" and stops overboosting after 13psi.
Lowered static compression "is beneficial" after 13psi or about 220whp (dynodynamics, higher on a dynojet).

Is this a problem? If it is, I'm happy to kick you in the nuts FROM BEHIND because I'm a ganxter ************. Call the cops, I don't give a ****. 100% not ******* around; I'm the most badass ************ you've ever seen, in your shitty failure of a life. Don't gay up my dyno thread with this **** because you don't want to **** me off. I'm happy to meet up with you at MSR-H and pull you around the track IN FIFTH GEAR, ************. You will sit down to make #1. I better not catch you making #1, standing-up.

I forget, are you running a MS with EBC? If so, you can proportion the part-throttle EBC duty cycles so that the part-throttle boost build is modulated better. It would definitely help with oversteer when accelerating out of a corner IMO. Once you have the EBC tuned, this is easy to do, like 5 minutes in megatune.

Hustler -
Congrats on the numbers.
I noticed on "that other forum" you've consigned yourself to a desk gig farther North in the Tejas Republic. Are you going to visit the Alamo City for S/S Mesh before you go, or are you going to channel your inner Bedouin and migrate from time to time?

I forgot all about that. I may...not sure. I'm in Austin today, going to SA tomorrow for an auto-x, then houston next week, then Dallas for the weekend.
I'll have to try to set something up with you later; I'd love to take that mesh off your hands. As for the migratory pattern, I plan on running at Harris Hill a few times per year. I have to build some respect if I'm ever going to get a seat in a proper race car.

Sure its the same turbo, and comparing my data log shows an identical spool-up :( rpm, but 30whp/40wtq more
