     I was going to let these guys build some custom  intercoolers for me. 
You could try them first and let me know how good they  are :)

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.
