Valid question, here is my academically unqualified breakdown:Does sucking in "hot" air matter if it's going through a hotter turbo? I'm just wondering. On N/A cars yes iat matter on the intake. How hot does a turbo get that blows hot air that goes to an intercooler?
Hotter air is less oxygen dense than colder air, because of this the turbocharger has to work harder to compress the less dense air to achieve the same level of boost as it would in cooler conditions. This principal also directly applies to how humid the air is as well. So if you live in a hot/humid place like the south or on a tropical island, reducing your IATs is one of the most important thing you can do for power. This also applies to N/A cars, but not as much - meaning an N/A car will scale less power wise than a turbo car would in the same climate.
