more HP means more heat.  But I wouldn't think that that amount of gain 
in MAP would add that much heat? thats only a couple inches over your 
normally aspirated numbers.  But then you haven't run it much normally 
aspirated right?

> When I got to the hangar this afternoon I jumped into a diagnosing my turbo problems. I checked out the turbo and it moved easily and freely with no noticble physical damage. I cranked up the engine, crawled under the wing and removed the hose from the intake and felt if I could feel any preesure out of the hose from the turbo. No joy. I couldn't feel any air movement. Ok, shut her down and went to the other side of the engine and removed the hose from the outlet of the turbo compressor. Cranked her up and felt for air out of the turbo compressor. I felt steady moderate air pressure. How about that. Data. I also could see the compressor spinning nicely.
