goodluck with that one man 
just wondering though - if your blown engine with 17psi+ (im guessing from what you said about the belt slipping at 17psi) shoved down its throat makes almost 400hp. what on earth is going to get an n/a engine up to 300hp?
seems optimistic to me, but id love to hear the plan for it all the same.

With a big stick and some decent compression, 300 hp at the treads could be possible! It will take revs and lots of them though. Would definately be a pig of a street engine.....

thats some decent numbers. i notice you refer to the yank parts, they use slightly different names for there V6 engines there S1 engines is the same as our buick 3800 engines used from VN to VR there s2 buick engines are what we call the ecotec. it'll be good to see someone hit the 300rwhp n/a with a V6.
damn yanks, cheap, high quality engine parts for the masses. who cares about global warming
