I need help understanding something about engines. I want to install a new 180 horse engine from Van's in my RV-7A.
I want 180 horse, but I also want to run auto fuel. I am told that I can do this but it depends on the compression ratio.
So I'm guessing I can change compression ratios in the O-360.
1. Changing compression ratios is done by changing the pistons, right?
2. I don't understand how this works, but does changing the compression ration change the horsepower? If I make the compression ratio suitable for auto fuel, is it still 180 hp?
3. Van's recommends I talk to someone at Lycoming. Anyone have a contact for someone at Lycoming?
Thanks!!
