Good day.
Thank you Larry and John for your contribution about the turbo. I
agree will all that was said, although it will be nice to have the
extra speed and power as I'm a bit of a speed junkey.
Regards
Tiekie

It was suggested that a "constant speed" prop would benefit a turbo
installation and that is true but a "constant speed" (variable pitch)
propeller would benefit any type of engine, gas, diesel, turbine.
There is benefit to a turbo with a fixed pitch prop in that the engine
is capable of producing more HP on takeoff and climb and continue to
produce rated HP at altitude. It would require a prop with more pitch /
diameter to handle the additional HP and additional modifications to the
engine / airframe to dissipate the engine heat from from the extra power
generated. Many modern automobiles are going to smaller turbo-ed engines
to increase mileage numbers but not without reliability concerns. Design
out as many failure points as possible and have a disciplined operating
procedures. Many do so successfully.
