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.

So, I rigged an alternate plumbing route and bypassed my intercooler. I also removed the pop off valve as it over complicated the rigged plumbing.

I got it all buttoned up and started her up and recorded my readings like yesterday.

They were as follow:

2000 - 14.1
3000 - 15.4
4000 - 20.2
5000 - 26.4
6000 - 30.3
6200 - 31.2

Hmmm, seems more like it. So, it seems if I may need a new intercooler unless I am missing something.

The new power surprised me as in just the short time I was at the higher power setting, the time it took to write numbers down, I overheated. I have had no heating issues since I modified my radiator location back in April.

Again, this is with a 3 lb spring on the waste gate and 93 octane fuel

Thanks for y'all's input.
