Was out on Friday night in AJC's RS1600i trying to find out why we can't run more than 6 degrees ignition advance without det starting. Did a datalog run and then watch some alarming figures in real time.

These figure were air charge temps. They were rising as fast as the boost pressure and this was on a Pro Alloy single pass cooler on a T34 at 26 psi boost. 65 degrees C peak temps. As soon as it came on boost the temps just shot up.
