Paul..... I talked to my associate . Here is the response.........A   TO4E44
turbo compressor trim 57, AR 60 , Flowrate 50, Max. flow 50, Turbine

wheel 76

,  housing  AR   84 .   It will have a divided inlet and a clamped outlet.
That will cost approx 704$    For another 175 we can put in a one piece
journal bearing , non rotating with a 360 degree thrust bearing

assembly.  We

will also put in a double wrap sealing ring as opposed to a gapped sealing
ring . I would highly recommend the bearing upgrade for a VERY low turbo
failure rate. Hope this can help you. Please keep in mind that ANY turbo can
be modified !! JIM DANA

Sounds good. I assume the divided inlet is a dual scroll. I am not
familiar with the term "divided inlet". Do you have a picture?
I don't think we need a dual scroll.

Also what is "clamped outlet"?

We also need Inconel wheels. Sorry I forgot to mention that.
How much for that option?

I also assume this is not a water cooled housing. I am sure the oil does a
lot of
cooling so it may not be necessary but since we have a liquid cooling

system it

might be nice to have a liquid cooled turbo charger.

The divided housing question was answered but I thought there may still be
a question about "clamped outlet".  That refers to a mod to provide for a
Marmon V-band clamp to attach the tailpipe rather than the heavy and
cumbersome bolted flange.  I think every 13B turbo should have a water
cooled center housing.  The benefit of a divided housing can only be
established on the dyno.  The added friction sometimes offsets the blowdown
gain.  That said, the divided housing is a good guess for better street
performance and a non-issue for aircraft because we are wasting always.

Also I might add it is harder to design a waste gate passage in a dual
pipe manifold.
