One simple question, how many of those wet sump blown up engines were using an accusump? CR

In a car environment the motor stays (hopefully ) flat around the corner - oil tends to leave the pickup area. The smallest air bubble at 11K rpm and a big end bearing is probably going to suffer, you may even ventilate the crank case - both are bad. Sump baffles can help lower the probability of this happening. - the dry sump system will lower the Cof G for the motor - usually a good thing If money was no object - the motor would be dry sump 10 times out of 10. But we all live in the real world and money is always in the equation - oil pan baffles are always less expensive and designed properly work well. The dry sump system will probably provide an operating scenario of greater dependability of system operating oil pressure over a greater variety of operating conditions. But, it costs money to purchase and it is another electro/mechanical device that WILL fail without proper maintenance and may even fail with proper maintenance. A story: I was talking with a custom component builder who attends the run-offs all the time. This year there was a team running the Kawasaki ZX10 motor, wet sump. Three days of running - lost three motors. Borrowed a ZX-10 with a dry sump - no problems. Were there other circumstances????? > Good one Mark!!!!
