luc... you are preaching to the wrong quire for lack of a better term. You are talking to me first of all, who has always and will always stand by common sense in this area. preach all you want, but OIL is ALWAYS better than NO OIL, even if it only reduces the amount of time with low pressure. The other person, Kai, is someone who just lost an engine due to Oil Starvation on a track... WITH a Comp Coupe Pan! Would an accusump have prevented it? No one could know. But depending on the length of the turns and other variables, yes, it may have. Your example of "how many race cars" use the systems is also way off base. First of all... how many PROFESSIONALLY BUILT RACE CARS do you see running a WET SUMP? almost all are running Dry Sumps. Second, There are quite a few more race cars running Accusumps than you seem to think. In fact, LOTS of them comes to mind. head to a local oval track, and I bet you will see 50% or more of the Non-Dry Sump cars running them.
The Answers are still Yes, Yes and Yes. He did not ask for analysis, just answers. It is up to Kai to make the judgement. Does the Accusump Pre-oil? Yes. Does it improve oiling while underway? Yes, by eliminating fluctuations. Does it eliminate Starvation? Yes, to a point- so long as its mechanical limits are not exceeded. 3Qt's may not seem like a lot, but Oil Pressure is not an On/Off switch either. that 3 qts smooths out the oil pressure, instead of a 0-5-50-20-50-0 situation, you have a 40-40-50-40-50-40 situation.
If I was a bearing, I would ask for an Accusump.
