And also there's plenty of racing classes that do not run intercoolers because it's unnecessary restriction.
All of my posts I've tried to relate to the fact that the intercooler pressure drop is effectively only due to restriction. The denser air after the intercooler is nice, but 99% of the time not responsible for hp gains, and has nothing to do with the source of the pressure drop. Things like velocity change with that density due to core restriction. I've beat this past dead, and I'm not saying anything about how important that aspect is vs others. Just simply trying to explain how that one piece works to try and kill misconceptions. "
