440 w/TorqStorm SC - Boost Getting Into Crankcase?? Valley Pan BULGE

@yellow rose the blow through in this application will be the best case scenario. The latent heat of vaporization will give him an intercooling effect. It will be significant up to the point that the blower becomes inefficient. Which, with a torquestorm on 440 inches is a small window. I would say he’s pretty safe up to about 8lbs of boost. And it should have a rising boost curve through peak torque so he may only see 3-4 psi at that point. Anything more than that IMO this thing will stop making boost and become a giant heat pump and all the things you’re talking about will ring true. We need much more info from the op on machine work and set up. And what it took to get to his power level. We have no idea if he’s at 10:1.
