This is so easy to prove.
This is the first thermal efficiency test during development.
Simply tune a non intercooled kit.
Add intercooler only.
Control the coolant and oil temps.
Do a back to back run.
Datalogs will show you something simple.
All else equal lower iat boost power massively even with the extra pressure drop of the intercooler (fmic or air to water).
Yes, we do have semi aggressive timing reduction from combustion temp compensation but thats just good to leave alone for safety. Can post the map for you to see.
During development we turn off all compensation tables inc knock sensing so we know what is safe and not just the dme.
We did a huge amount of testing for our s62 intercooled kit. IAT was king again.
The thing is..... it always is and we have physics to back that up.
