It would interesting to see dyno sheet over lay of this car and murlos car. you guys are close in power.

Well although it may be overcomplicated, the boost control works. I think straight 3port (or 4 port) is the way to go, but I don't think the dual wastegates is a bad idea, I have seen that make more power over just internal. It overspins the turbo yes, but if you want max power, do it.

I tried using fotoflexer to overlay mine from the dynoday and chris's 4th gear pull. Fotoflexer wasn't working...I was going to post in my thread as to not clog this up. I guess if someone is feeling bored by all means do the overlay. Maybe overlay mine, scheides and chris's for 2.0l vs 2.2 vs 2.4 (really 2.5 I think). Might be really clogged though with all the dynoday runs, would be better to do it at MAP on their comp.

How do the 2 WG's overspin the turbo? Because it's holding more psi?

Yup, higher boost in the higher RPM's.

Why does the 3rd gear graph show that the run starts out with 6psi so it spools faster or something?

Why not just do a 5th gear pull and say it gets full boost at 2500rpm?

Looks like it spools about the same in 3rd & 4th gear to me, maybe 50rpm difference.

Maybe you should look again!!

Sure looks like the boost stops going up at 4000rpm witch would be spool right? Or kind of spool since the boost starts at 6psi!
