So I used Scott's example from earlier and ran it through the calculator from the link.

From the actual calculations. (Stock Boost of 11.5 psi up here)

Hot intake of 100° --> turbo --> 253° --> 95% IC --> 79° Intake Temp

CAI --> 70° --> turbo --> 215° --> 95% IC --> 77° Intake Temp

IC efficiency is more like 85% I think. I have been wanting to set up an experiment to measure temperatures on the IC for a while, maybe I'll borrow some TC equipment from work this weekend ...
