Hi Dian, I USE a controller to operate my turbosupercharger.

I use NO Waste Gate OR Exhaust.

i was actually referring to the original question. there are two ways to make a turbo act as a centri without complicated controlls. using a big turbo (mentioned earlier) and using "boost creep".

Hi Dian, I also use a VNT turbo from a Ford Truck and install a larger compressor wheel/cover/seal plate for some applications.

There are more than two ways to to operate a turbocompressor.
1. Electrical operation as used in F-1
2. Hydraulic operation as used by BV on ships.
3. Self Powered operation used on WW-II fighters

NOW for JoeNova, YES a have made a LS-400 Diesel with four valve heads.
This was for the Battle Field.
The head was made by Russ Arao.
I fitted my ECU-882C with a DDI power board.
