Alan, thanks for the temperature references. I'm going to check my vmax7 and see what temp. it's running. I do know that Lite Machines recommends 25% nitro content for the vmax7.....which I used in the summer but this winter I'm using 15% Omega (it's cheaper). I do have to run it leaner.....a little less than 2 turns out....but the engine doesn't boil spit. I have a point and shoot thermometer so I'll check the temp the next time I fly.
