Unless you're running a stock type oil pan I see no reason to believe there would be an E.T. gain by draining oil from the engine.Basically the only thing you're doing is reducing windage in the crankcase. With a properly designed pan, scraper and if possible windage tray draining oil is only going to hasten the death of your engine. I would opt for some of the ultra low viscosity oils instead, at least you would have a steady supply of lube to the bearings, although it does have the consistency of water, some lube is better than no lube. As far as running the engine "cold" I do that. After fully warming the engine I leave the water pump and fan on till the water temp is ambient, seems to be a little faster, of course you need a pretty effecient cooling system to accomplish this in later rounds.
