replied to the thread Intercooler Comparison (BMW Stock vs. Wagner EVO1 vs. HPF vs. Mosselman)
" I disagree with a lot of what is being said here. On a fundamental level your colder denser air charge out thru back is going to lead to a larger pressure drop as the denser air required more volume flow of hot air on the inlet side. More volume through the pipe leads to more resistance. This is obviously a simplification, but this the basic premise.
The tire analogs incorrect because V is constrained there and here it is not. If you conserve mass V and T can scale together. That doesn't mean they will maintain the same ratio exactly, but its not constrained. "
