Aye, most people think that if boost is good , then more boost is better.Originally posted by RDS
You don't need more boost, you just need more air, ...
Actually, boost is NOT good - why should it be? It's just resistance to flow. More boost means that you're trying harder to squeeze air through the same restrictor (that's the engine!)
And this Boyle's law has nothing to do with turbos. The more you squeeze the air, the hotter it gets (if it can't expand accordingly) - that's irrespective of turbo/supercharger or anything else.
Here we're talking about *extra* heat, over and above the thermodynamically minimum.
RDS is right, a bigger turbo will add less heat over and above
Yes, the intercooler will dump (in the engine bay ) most of it, but it's better to avoid it in the first place.
