Max hx-40 and 370 marines hp?

I'm going to guess 427hp
today when i was going through some papers i found my old dyno sheet with my hx40 and 370's and it was 428hp. but my guess would be around 500 max thats pushing that turbo pretty hard.

Haha! Man it is a small world! I don't run it much because the guys that will race aren't usually competition and there are too many cops. I was down Friday night at dunkin donuts parking lot for awhile....
