This is about the best turbo charger 3D model I have done
so far. Next is the exhaust manifold with waste gate to fit
a Lancair 320. Maybe just a PicAXE controlled pop off valve.
Should have around 400 HP available if necessary.

I am thinking of getting Jerry to weld it up out of R.B
Wagner .090" wall thickness  SS bends.

Paul Lamar ...No rotor no motor.

Paul,

This may be an incredibly dumb question but why can't we rotate these
turbos 180 degrees so that the compressor is in front  of the turbine?
All we are doing is using the turbine to compress air for the intakes right?
Then there would be no crossing inake and exhaust.
I must be missing something obvious.

Cheers,

Steve

We can. Tt just takes a custom exhaust manifold. The TO4 takes a custom manifold
anyway so I will put the turbine on the back side.  The beauty of the stock 1991 set up
turbo, manifold and all is.... it is compact and cheap.
