Our single turbo is too small and it generates too much exhaust back pressure. Our 30 lbs / hour fuel injectors are too small too and we had to raise the fuel pressure to compensate that.

Still, 329,5 Hp at only 4900 rpm and 630,3 Nm ( 465 lbs ) of torque at only 2600 rpm .

Torque and Hp numbers kept going down as the revs got up and exhaust pressures kept increasing and there was no need to pull more than eight pulls because we didn't get more horsepower out of the mill. But every time we screwed more boost pressure, the torque increased. And we used only 0.7 bar ( 10.3 psi ) boost pressure.

I will post the dyno sheets later and also a link to a short video at youtube after I have made it.

Ok, and we didn't broke anything exept one Crane Xr-i module due false wiring. ( Damn Simo )

Here is a video of that session... http://www.youtube.com/watch?v=8yFwrPj8SnU  enjoy!
