Chigger, The large quantities of oil do not help cool the engine, it just prolongs the warm up time until all the oil is up to a useable temp. All the oil must be at 180 deg. F before you run the engine hard our you may have problems. You must run a good cooler and thermostat in the system. Most racers that use drysump systems have heaters installed to preheat the oil and reduce warm up time.

Chris, All the bearings are pressure lubricated, the pistons and cam/lifters get "splash" for lubrication but if there is too much oil getting wrapped around the crank it costs HP. I think squiters to the pistons, cam/lifters with quick drainback is the best way to go.

Wally, I have heard that the 914 windage tray can actually make the problem worse by not allowing enough oil drainback on high volume systems. I don't have any experience with it though.
