I dunno. How far is that from the dragon's belch? All I can tellya is
that they sure last a hell of a lot longer than 40hrs in an aviation
app., but then again, I also dunno if anything special is done with EGT
placement when you run turbo in an aviation engine; never even flown a
turbo'd aircraft, nor looked closely at one. Maybe I should!
