I'll see if I can help here before Sherm' jumps in to rain on my parade
I AM SURE HE WILL HAHA
1. A larger pipe size should cut down on flow resistance,but will take a tick longer to fill and create back pressure - boost.
A OK makes sense but wouldn't that depend on how much you need to flow
2. As was pointed out to me a long time ago,"wind chill" is an effect that occurs due to moisture evaporation from human skin.
It doesn't affect this situation,as far as I know.
A - I have heard that before BUT how does a heat exchanger work--doesn't a rad sweat Why do I need a rad then or intercooler for that matter.
3.More boost pressure means denser air which is harder to move and has more momentum than ambient air which will cause most airflow anommilies you see to be exaggerated over what you would see at ambient air pressure levels - 0 boost.
A - More boost and or resistance also means more heat. Where does it end.
That's why the larger pipe flows with less resistance.
It's like moving 50,000 cars down a 20 mile stretch of 4 lane highway in one hour as opposed to doing it on a 2
lane highway.
You see this at rush hour around a lot of cities.
