I have no idea why the plane is slower than it should be. It's still great to fly, but I just don't have time these days to really track it down - nor am I an aero expert who knows what to look for. Going to try a few small mods in April when the next annual is due.
Oil temps are fine now. Usually around 180 -190 in cruise. Can get up to 230 in climb in the Summer. Overall it doesn't have to be managed very closely.
As far as comparisons go, I'm hoping to do a side-by-side speed run with another guy who has a -390 in a -7 as well. Will post that when it happens, probably later in the year.
