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,
