I have no fear of boost. I just don't see the point in making more power than I need. With my cam and ported heads and intake as well as compression it's not a stretch to think that it will make 240-250 HP without boost. Then add 15-17 psi and probably close to 500 HP. Boost is just a measure of restriction. An engine that flows more air requires lest boost to make the same power. I'll be happy with hp between 500-600.
The lower the boost the cooler the intake air temp and the less chance of detonation on pump gas.
