I have not ordered my engine yet, and have been leaning towards the lower compression IO-375 from Aerosport so that I could use mogas if 100LL goes away.
Since I have spoiled myself for many years flying high performance aerobatic aircraft, of course I now find myself thinking of higher compression/hp ( maybe even that Superior XP 408AC!) and since I don't plan on using mogas unless I have to, I started wondering how involved it would be to lower the compression ratio in whatever engine I have, should it become necessary. I am building a 7.
Both manufacturers offer low compression versions of the same engine. Is it just a matter of changing out the pistons? I know that may be an expensive and involved undertaking, but it's cheaper than buying a new engine.
This will be a question I will ask each manufacturer of course, but I wanted to get some thoughts/opinions from the community here as well.
Thanks!
