I have been reading the engine manual for my IO-320-D1A and various threads on engine leaning and I can't seem to find the best procedure for a full-throttle run at altitude. I don't plan on doing this often, but I want the best procedure to avoid harming the engine for a few brief WOT runs at approximately 8000' DA. Normally, I'm doing "performance cruise" at 2300-2400 rpm with mixture slightly LOP.
My thoughts are full rich initially, but can I lean to peak rpm or 50 degrees ROP once the throttle is fully in? The engine should be producing less than 75 percent power at this DA.
Sorry for the noob-ish question, but most of my flying in rental planes to date has been at 3000 to 4000 ft, and now my practice area is in SoCal's high desert.
