Tried som I-Phone video today.
I was out and did some fine tuning and this video is with 80% wot in 1+2 gear and 60% at 3, that I could see in the log I did. Boost peak 1.5 bar and then direct 1.25 bar.
I promise I will try to do a better one with wot all the way.

Wow, sure is a pretty piece. I was just curious, as I have an extra intake manifold laying around and was thinking about doing something custom with it. I have to say though, the car is beautiful, under the hood and cosmetically. Great work!

+1 on the open honest discussion.
I still wonder on your boost levels, afrs, c/r all adding up to a pretty high c/r during combustion though...but the proof is in the pudding as they say. So long as it's holding together then that's proof enough. Also you mentioned that the turbo is going to run out of it's efficiency range at much over 19psi but that seems odd since you have a GT35. Isn't your hotside a .82? They can clearly handle over 19psi or am I misreading something here? Overall I'm not disagreeing with your attempts to make the car most efficient at lower boost levels though. Good for longevity.
But we need to see how much you drive it and under what circumstances. Just street boosting or more sustained loads? Any track time?

I have no problems so far. I drive a lot at the street and if I go on track I run 1 bar and still have 450 rwhp. My hotside is 1.02. Yes the GT 35 han handle higher pressure but in my engine with my air exchange is at its max at lower boost as I have a good N/A built engine wit a lot of off boost power, the efficiancy is high. Thats also why I have dynoed 450 rwhp at just 1 bar. How many here have that? Anyone?

Just wondering how your car compares.

Interesting. 800 C is where my car usually sits. Dropping to 500-600 on a slow cruise. Is 800*C a peak figure? If not what does it peak to if you hold it on boost for a while. Sitting at 4500rpm in fifth so the turbo was constantly spinning and giving it a few bursts to 6000rpm (following a nice Aston back from Le-Mans) I noticed I was seeing just over 900*c or around 1800 F. Air temp outside was mid 30's*C but cooling should have been very good at those speeds.

Ok. Well... you can have even moore power at 1 bar also can I if I chose a turbo with bigger compressor but its always a compromise with driveability as you know. The one you show had a 65 compressor, a bit bigger than mine.
It also differs a lot beween dynos, the Rototest tha I dynoed on is very accurate with a 1% tolerance.
