Apparently 480 AWKW was the most power out of a 8374 awkw (out of an Evo) Scott has seen on his dyno.
Nick (3.0/8374) went 461, 24 psi
Pete (3.2/vcam/8374) went 457awkw, 25 psi tapering back to 21 psi (120,000 turbine speed).
I don't know. It's all dictated by that magic 127,000 RPM turbine speed. What will be more interesting will be the boost level that it'll need to get there. Going off the -5 setup, it went 441 at 19 psi. Realistically, I should have just left it there. Boost level I'm gonna peg at no more then 25 psi, tapering back down.
