Bob,
Now that I presume you have put several hours on your 13B/Turbo installation I would
like to ask a few performance questions............I have been going through compressor
maps from "Turbonetics" and was wondering what boost numbers you are seeing at
various rpm's and altitudes from your 60-1 turbo.............I am looking at the TO-4E with
trims from 50 to 60 and of course your 60-1.............Several of these turbo's would do
a reasonable job but I would prefer to chose one that will be most efficient at about a
maximum 5 lbs or less boost (1.35 pressure ratio) and at the lowest turbine rpm..........
I probably will not find one that is perfect but will try to pick the best compromise from
the choices.............John Slade if you read this would appreceiate some of the same
info on your TO4E-50 as I believe you have the most hours on this Turbo...........
Bob I realize that you have the 1.15 a/r turbine housing (which I lean toward to avoid
overspeed at oxygen altitude) and John you have the .96 a/r housing for moderate
altitude.............Another factor is if the propeller pitch is fixed or adjustable.........I have
a inflight adjust "IVO" as does John Slade and I do not recall what you have Bob.........
Thanks in Advance,
Kelly Troyer

My turbo is a Turbonetics 60-1 compressor trim, with 1.15 A/R divided tang, oil to bearings, and water cooled. See the following link.

Curious as to the make,model, Compressor Trim and A/R of the
Turbine housing of your Turbo ??...................
