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

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 each.
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? :)

Though I got my private in 1964 I am a low time pilot but have 7000 hours as a military and civilian flight engineer.

Ah that explains it. You had nothing better to do than watch the EGT constantly :)
