At about 3500 vtec comes in and askes alot more fuel. The minor dent in boost level is hard to get out in this configuration. But I don't think you'll notice it on the road.
The turbo is making about 2.1-2.2bar boost. That's about 30-32psi. The boost is the lower line. As you can see it's at 30psi most of the time with a small peak at 7800rpm. We couldn't really figure out why. But hell, it was 02.30 in the night!

Fantastic build! I'd love to see this car on a typical US based dynojet so we can get a more apples/apples comparison to the numbers and power curve most of us are accustom to. From what I've gathered peak is roughly 500hp/500trq?
Also, I'm curious what rpm you set the vtec transition point? Looks like there is still quite a "hit" in the power curve, just wondering if its vtec related (to high a transition?) or just the inherent nature of the set up or dyno reading becuase its in NM, being more pronounced then actual possibly. Just wondering becuase I thought the idea was to get a smooth powerband, to where the sc is filling in the dead zone before the turbo comes into its efficiency range, producing a fat but linear trq curve.

The torque is measured in Nm. 732Nm is 540 ft lb (http://www.theunitconverter.com/foot...ton-meter.html)
The power is measured in Kw. 565.3Kw is 758 hp (http://www.convert-units.info/power/kilowatt/565.3)
The boost is measured in Bar. 2.1bar is 30.5 psi (http://www.evi.com/q/convert_2.1_bar_into_psi)
Vtec is set at 3500rpm.
The powerband, even more the torque curve, is much better than without a supercharger. Maybe we could fit a bigger charger and get more power out of it, I don't know.
What I do know is that this is going to be fantastic to drive!

I never thought you make this work but you did. Congrats, great job.
Now they know what to do.
Any runs with just the blower? What size blower again? And how big of a blower could you fit? Lose ac though right?

We made runs with just the blower but since we turn it off at 4000 rpm the chart is the same. The turbo really doesn't do anything lower than 4k.
The charger is an M62 eaton. I think we could fit a larger unit.
I still have the AC since we relocated it to under the exhaust manifold. You can find pics of the fabricated mounts in this thread.
