Still trying to separate rational from irrational risk! I was in the same place when I was starting out with this LOP stuff... Just climb to an altitude where you're at 20" MAP at full throttle with boost on, (not hard to do when you're at 5700 ft before you leave the ground). Now with an RPM of 2500, you're only making 65% power. Now you're safe and you can play with the mixture all you like. Go as slow as you like through peak, noting the numbers, both EGT and CHT, feel the power reduction as you get to about 10° on the lean side. You can go back and forth across peak to get super comfortable with all of it. Since you're at low power, you can't hurt anything. Maybe we can go fly this weekend? I'm free Sat afternoon and all day Sun. 2 1
ArtVandelay Posted May 15, 2020 Report Posted May 15, 2020 I’m not sure about the concern for the red box is warranted. This is why we have engine monitors, if the engine starts detonating, the monitor should tell you immediately and you can just pull power or go rich.
