10psi-100hp
20psi-200hp
30psi-225hp
those are my rwhp guesses...maybe more if you use meth!
lol seriously thats hard to do which explains the lack of responses to your question. Only advice I can offer is do a thorough search and see what others with similar combos are making and kind of take it from there. Also, why a 67mm and not a larger one?

It would be tough enough to guess just by going with what little info you've given about the set-up. Like...when you say "67mm tubo", what exactly is the full spec on that turbo? You need to be much more specific in order for anyone to even begin to guess what kind of power your set-up could possibly make. How about the cylinder heads, aftermarket or stock?

That turbo may be capable of 35psi, but not on a 355CI engine. That turbo will run out of breath long before you get to 35psi.
Instead, you should look at how many lbs/min of air the turbo can move, and that will tell you how much power it can make. From the description, the 67mm turbo seems to be your limiting factor.
My guess is that you could get it to 17psi and max out the turbo at 650whp. Any more boost than that and it will just be creating more heat than power, and you will actually start to see power fall.

Im not trolling, however based off some of your statements you have very little knowledge on the dynamics of a turbo system. If you would just search or read other topics, more importantly the STICKY's, you would probably answer most of your own questions. That turbo is entirely too small unless you plan on putting two on there.
