How does "in line with most other dry sump systems with billet oil pans" convert to USD?
Google searching "Dry Sump Kit" for other 6-cyl engine applications like BMW M3s and Supras, and looking for the kits with billet oil pans will give you a ballpark idea of the cost, in USD.
I'd suggest learning a bit about them, the components that make up a complete system, and determine if this is something you need or want to give you piece of mind.
Yah, not interested in the front drop spindles. Dry sump idea seems interesting. Am I correct to assume the point is to eliminate the potential for oil starvation from sustained cornering as well as eliminate the weak link (oil pump gear) in a money-shift? So this would compete with one or more of baffled oil pan, accusump, and aftermarket billet oil pump gear. Or is there some other consideration/motivation?
Yes; the NSX is known to have oil starvation problems, especially in right-hand sweeping corners. This is why a baffled oil pan is a MUST for tracked cars. Once you start putting modern R-compound tires, slicks, and or some aero on them, the stock oiling system struggles to keep oil in the pan without exposing the oil pickup tube, sucking air, and leading to a very expensive engine repair.
Accusumps are a cheap $700 fix, and provide a small layer of protection with a lot of headaches and complications. They are slow to react to a drop in oil pressure, a bit maintenance-intensive, have been known to leak, electric valves don't always function properly, manual valves are a pain to constantly open and close, checking oil level is a pain, only provides a few seconds of protection from oil starvation and will not help in long, sweeping, sustained corners, etc... As tires get stickier and people start using more and more effective aero, the benefit of the Accusump is limited and in some cases, are not enough. It took a few blown motors (due to oil starvation) for FXMD to install a dry sump in their race car. From then on, we never had an oiling issue or motor failure.
The goal for this dry sump was to:
- Retain A/C
- Be worry-free and ensure the engine would never starve of oil- regardless of how good of a driver you are, how sticky your tires are, or how much aero you have on your car.
- Increase oil volume to ensure both the bearings and oil-hungry VTEC solenoids have enough oil at all times.
- Eliminate the need for ugly and messy catch cans (you plug the valve cover vents and the scavenge pumps pull a vacuum on the crank case)
- Eliminate the need for an electric turbo scavenge pump (another stage can be added to the dry sump pump to scavenge the turbo)
- Avoid the hassles of an Accusump
- Bolt on to a stock block without touching the main caps or requiring the motor to be disassembled and machined.
