Will heat increase pressure, yes. Does boost equal heat? Not necessarily. I wouldn't be worried about how much boost it takes to make x amount of horsepower, because the cylinder pressure will be the same nonetheless.

Any combo that can achieve xyz power level using a lower boost pressure is ALWAYS the safer and more reliable setup. The only thing that often prevents using compressors large enough to achieve it, is spool. So it's always a compromise. |

Ok. You are saying that power is the ultimate limiter on stress concerning the cylinder walls, crank, rods. Ok. I'll buy it. Now, let's talk about pre-ignition, hot spots,etc. you show me how you compress air without heating it up as you increase pressure...
I'm not understanding how you figure it isn't best to have a more efficient air pump before adding boost? The less you heat the charge, the less chance of chaos. There is no free lunch on a restricted platform like this. Huge intercoolers block more radiator flow, and pre-heat it. Now the coolant runs hotter, as do the jackets, and cylinders,etc. Never mind the added load of having to soak up more heat because of the extra power. That's all we are saying. Why run 15lbs of boost and the headaches it creates, when you could improve your air pump to only need 8psi to reach your power goals? I've dealt with a ton of turbo builds, and I know more boost always looks cheaper and easier, but never is!

Improving the method of Forced Induction I can agree with, but a motor with a larger camshaft using 8psi versus a stock engine using 12 psi the difference is negligible.
