I have switched horses-- but not in mid-stream. ordered Patrol plans. I came upon a nice older maybe overhauled o-320. Thought that would be a bit wimpy for the 4 place but maybe less so for a patrol. The engine is a narrow deck 57 model before they started using the banana plates.
I am thinking what I might do to it (to add some HP ) that would not affect reliability or overtax the components.
one thought would be a tuned exhaust. Is there more than one brand of those ? Has anyone made their own ?
another might be a polish job of the intakes. I have heard that tuned exhausts give 20 extra HP when the airspeed is below 40----
and the intakes couid give 5 extra. (?)
I dont think I will mess with the pistons since they are new. I wouldn't think a turbo would be good on an early engine like this--
Any thought on perking up a little---
Im thinking 150 would be adequate on a patrol. Probably slightly better climb than an older 172 ????
But thinking that another 20 might be could if it was "free".....
