To all the fast guys with IO-540's:
I'm looking to fly my first race this weekend in my F1 (125 nm, roughly 35-37 minutes). I understand there is typically little problem with running at or near 2,700 rpm, but the real question is how much MP? Mine will pull (according to the engine monitor) just over 30 inches on T/O, but that kind of horsepower for that long seems inadvisable to me.
If it's not wise to run wide open, what power settings would you guys with 540's recommend? My Rocket has a K1G5 running ECi parallel valve cylinders, running slightly pumped up pistons at 9.5:1, if that makes any difference.
Any helpful information would be appreciated.
Thanks,
Lee...
