Also, since when is 24psi not high boost?!?!
Show us a 32psi run on the dynojet!

What kind of turbo is it again? The Vietesse Stage III one?
Jim has the complete Stage 3 kit (Turbo, MAF,..). He also has the Vitesse big Valve head.

John, I`m on it! 
My head is at a machineworkshop for solving the problems with the valves. I hope he`ll be ready with the head this week! I`m hoping for some nice numbers when I i get the head installed!

I dropped the thottle a little early - probably had another 10 horse, or so. I like to be easy on the equipment.
I will be going to the dynojet in a couple weeks - I am not really worried about seeing a 500+ RWHP dynojet number, now. Should be a stroll by the lake.

The other thing I'd love to see with this would be some durability testing. Particularly with valves that are so large & heavy. I'd love to see leakdown #'s and valve guide / seat data after running the head at redline or nearly so (6,000 RPM +) for like 72 straight hours or something similarly brutal. I'm already sold on it as a great high-flow, high power head, but if it could be proven as a high-reliability, high-flow, high-power head, it'd be worth all the more.

). As far as the valve sizes, well there is more involved than just the size!!!

Vitesse is the best. Who else can pull this kind of power out of a 2.5 with such little $$. (I say little compared to everything else out there. . .)
