Is that your big secret? The diference in size between the turbine and the compressor wheel?

I have a good friend that owns TEC in Colorado , and we talk all the time about turbos in both passanger and comercial applications. He know's more than even your G*d, Corky Belll about building turbos and cause and affect.

Why didn't you get to the point instead of making me go after seperate yet applicable pieces of what you were asking.

BTW, cams do affect WOT output on a turbo engine. To say they don't is ridiculous.
