The turbo compound was designed to cause no back pressure in the

combined at takeoff power, or 150 HP each.

BTW Hurant you are much better pilot than I. I average 500 hours per

exhaust valve

on my O-470.

That's very possible. My Baron has two IO-470's with nearly 1500 hours

No cylinders or exhaust valves have been replaced during that period.

I guess you are a better pilot than me as well Harrison. Anybody else out

there want

to chime in? :)

BTW how fast do you cruise that gas hog? :)

Paul Lamar

Harrison, Paul,

care to compare how you operate your engnies?

EGT, manifold pressure, rpm, etc.    ..... maybe we learn something! :)

Well I will lean mine using the EGT scanner at altitude cruise and then forget to 
readjust the mixture when I descend :) Since I got a flow meter now that is a far 
more accurate way of adjusting the mixture.
