The panwillhave proprietary trap doors and baffling along with a capacity increase (YTBD). The majority of the oil returning to the pan is coming off the reciprocating assy. If you're inside theblock with a die grinder, anything you can do to promote oil returning to the pan is always worth the while. Both the two valve and three valve heads have generous return holes along the outside edge of the head, not at the front or rear, so with the head sitting at a 45* angle, and the return holes on the outside, you'd have to achieve min. 1G for the oil to be "suspended", but there's really no where for it to be trapped. In any other condition, gravityshould prevail. Also, there's really very little oil being thrown around in the top end, and no lifter valley for oil to be trapped in, as in a push-rod V8. The small amount of oil on the inside head (during cornering) shouldn't in any way compromise the oil system, even when not returning to the pan for a short time. (Even the longest sustained high G turn will only be a matter of seconds) Some oil may be trapped in the upper insides of the block, but I don't see this being an issue, especially with a well designed pan that keeps the oil around the pick-up, and is designed for these side load conditions. Remember, all you need is enough oil in the pan to keep the pick-up covered. (This is where a well designed proprietary sump is key.) Reducing windage, and the parasitic drag and HP loss associated with it is the big challenge here, IMO.

Yeah, I've had an oil temp gauge for over a year now (sender in the pan). I don't have an oil cooler and at this point I haven't seen the need for one. Even in 95+ degree temps last summer on the track, I never saw oil temps over about 220 degrees.

If I spend money on any cooling related issue, it will be for an upgraded radiator (my temps regularly creep up to 220 degrees by the end of a session).
