:--) wow that drive pressure is crazy

That's not bad at all to me. My first setup ran at 65 psi with 75 drive and that made a final 674 hp on #2, 706 on water at Piers's.

Was that the set up with the 42mm external wastegate Jim? You ran a big 18cm2 exhaust housing too right? This is with the stock 9cm2 housing over a B2. The boost numbers will be higher with a tighter housing is you can't control the boost on the top charger but I calculated the top charger boost out to be 10psi so it seems the it's able to control it. I wouldn't be surprised if the 40/3B and 40/B2 with the stock internal wastegate weren't close to those numbers. I make about the same boost and the same egt's I use to make on my '02. Hopefully when I get it back together it will make about the same power

Yep, you got it.
