Not sure if i read this somewhere or if i made it up in my head, but is there any truth to this. I thought i read that if you get blower cams its a lot easier way to increase horsepower that wont stress your motor as much as increasing boost. Is it like freeing up horsepower without stressing the internals. Basically, i want some more power but dont want to increase boost (i'm at 8psi) because i hear more than that is questionable on a stock bottom end. I'm at about 400rwhp/tq right now. If i get some blower cams, wont it lower boost and still make 450rwhp? So is that an easy 450hp with less stress on the motor and the stock motor will be fine? Or is it that magical HP number that makes it pop no matter how you get to it?
 
Blower cams (from what I remember) have no valve overlap. This keeps the boost from leaking out the exhaust. If you have overlap in a blown application then this provides a path for the boost to go right out the exhaust..

So, you will be keeping more of the intake charge in your cylinders. This will increase cylinder pressure and will produce more power. This will also put more stress on the engine.

You will most likely see HIGHER boost after you do blower cams because it wont be leaking out the exhaust.
