Let= us all know how well it goes for you in the real world application. I can'= t help but feel we are trying to fit a square peg in a round hole with Turb= o application to Aviation needs.
=0A
 
=0A
Personally for= myself, as I have stated before, I feel that I would use remote mounted tu= rbo, like some cars use (to reduce the heat and flow speed to the turb= o) and feed it from a bypass off the exhaust pipe. The by-pass could be con= trolled manually, for (when required) application. A wastegate does th= e same thing but the exhaust is taken right up to the turbo and carries the= heat with it. I think this would go a long way in controlling heat and ove= r spinning issues.

However you need the necessa= ry room to make this possible.

Bob, John and All,=0A
 
=0A
     Well I have bit = the bullet and made my decision for a turbo............After much research,= talking to Bob
=0A
and John and conferring with a "Turbonet= ics" dealer I have ordered a TO4E-50 trim (compressor wheel),
=0Awet bearing housing, big shaft "Q" trim (F1-68mm) turbine wheel and 1= .15 a/r ratio turbine housing.........
=0A
 
=0A
&nb= sp;    The decision what size turbine wheel and a/r rat= io housing was based on the fact that the f1-68mm
=0A
turbine= and 1.15 a/r housing causes less exhaust back pressure than the smaller wh= eel (bigger hole) and
=0A
will increase rpm less as you incre= ase altitude as opposed to the F1-65mm wheel plus the 1.15 a/r ratio
= =0A
housing will slow rpm increase for the same reason............=
=0A
 
=0A
    The decision to go wit= h the 50 trim compressor wheel (Like John) verses the 60-1 wheel = (Like Bob) was
=0A
based the "Flow Maps" of both wheels=  and my uneducated opinion that the 50 trim wheel would be runnin= g
=0A
in a more efficient area of the flow map base on the "Air C= onsumption Chart" (lbs per min) of the 1.3L 13B
=0A
that I submit= ted to the group in a previous post.............Of course for all practical= purposes there is probably
=0A
little discernible difference= between any of these turbo configurations mentioned.............
