Have you given any thought to changing your t-stat to the Mishimoto or RIPP 180deg.? I've read a bit about it and it seems you need some custom tuning to adjust fan operation but for forced induction motors lower coolant temp could be a small part of the power recipe. In reading about the t-stat I came across information about the pentastar oil pump system that has a step-up solenoid that gets actuated by the PCM based on temp., RPM, engine load, etc. Again, small items and I AM NOT MAKING AN ACCUSATION but if RIPP's test jeep/motor has a lower temp t-stat and a custom tune which is generating lower engine compartment temps and keeping oil pressure at optimum without taking unnecessary power for the pump then we might start to see a difference in dyno charts. Also, I believe (not 100% sure) that the coolant passages in the heads include the cast-in exhaust runners. I know that GM's 3.6L bi-turbo Cadillac motor works that way. The exhaust helps get the engine up to operating temp faster at low load. At high load the coolant helps prevent damage to the catalytic converters. But, maybe it would be beneficial for the turbo guys to lower exhaust temps across the board and lower heat under the hood.
