If air goes into the compressor 10 degrees hotter, it comes out 10 degrees hotter
I understand your thoughts but that statement is incorrect. I went to a professor of automotive engineering for the U of I when designing the above setup. Same guy that designed John Force's dragster rear wing and the same guy that designed the Indy F1 track and also holds a land speed record in the steamliner class. He took me to school on all of this.

If intercooler efficiency is not sufficient to offset inlet temperatures you need a better intercooler.

My wing is a GT2 which has air inlets on both sides. These inlets allow for any residual flow need at high RPM and also create a ram-air effect at speed.

The above setup produced a very significant increase in power by allowing a controlled amount of air to go around the intercooler at low speed and including ram-air at high speed. I've used this setup for a lot of years with no issue.

There are many threads on this subject and I don't want to hijack this one.
