Boost is only the pressure left in the intake manifold from the air the motor couldn't ingest. A motor with a tiny cam, restrictive intake, weak cylinder heads and a poorly designed exhaust might make 14# of boost and make only 300 HP. That motor isn't going to hurt itself.
The same motor and blower with a well designed blower cam, free flowing intake, heads and exhaust might have only 8# and make 600 HP. Less boost but much more air being ingested by the engine. Which motor is more likely to break a piston?
The perfect scenerio would be to have an engine with a perfect intake, head , cam etc. that made absolutely NO boost. ( Of course this is impossible) An engine that could ingest all the air the blower could put out might make 1200 HP. ( Probably much more) Now we have a motor with no boost. Now which motor would you expect to blow itself to pieces? Makes you think, doesn't it?
My theory is to use a smaller blower, spool it faster and tune it way down at the top. I have cars that make over 500 RWHP that only have 12 degrees of timing. That way they make better mid range power, come on sooner and still don't kill themselves up top.
I see guys installing my system and making 600 RWHP. That's fun for a while.... I usually make around 550-575 on a Z06 and then tune it down to 500 - 525. That's pretty good for a street machine.
Boost is only a number. There's MUCH more that goes into making a sucessful combination.
Just my opinion, for what it's worth.
