Sounds like a very healthy number Jon.
I've got no graphs as it was all over a bit too soon but here's what I picked up from the dyno display I was watching. In 5th gear at 81mph and a tad over 3k it was producing 19hp to turn the rollers and maintain that speed. On the first and only power run as the revs passed 3.5k it was making 230ish HP and over 250ftlb's. This is were the turbo just starts to make boost. The turbo can produce 650hp and that's just about the safe limit of a standard engine. We discussed a strategy and its along the lines of, HP in the mid 500's. Run a little richer than normal (11.8ish AFR) to allow more advance on boost. Avoid making too much heat. Run a very soft wastgate spring and control the boost with 2 solenoids so I turn it right down to NA if I want. Although I want the car to be quick, I don't want an animal that's a handful on the track.

Sounds like a good fun engine. Looking forward to seeing the curve now its fixed again.
Sounds right up my street! It's being added onto the watch list
Must sound fabulous at maximum attack!
