Yeah, that one is huge. A canton two quart one is 12 inches by 4.5 inches. I'm thinking it would fit above the manifold with hot side inlets.Oh i see what you mean. I haven't heard of any issues with the N54 starving for oil but then i don't track my car. Also don't know where you'd install that accumulator, it's pretty big.
I know VAC and Bimmerworld have baffled pans, but was considering an accumulator instead to protect against starvation on prolonged turns. Anybody have one?
Finally decided to tackle this.
What about a pendulum style setup for dual pickups that shuts the side opposite the g force but when hanging allows both open ,this way can use dual pickups on each side and whatever way car banks that pickup is forced to be used.
See my thread in the N55 section about spun bearings on track... I installed an accusump on my rebuild. Tucked a 3qt between the charge-pipe and the intake box. It fits perfectly. Not sure if it would fit there with the N54 stock airbox or some of the aftermarket filters though.
Accusump was plumbed into the top port of the return side of the oil filter housing (return from oil cooler). It would be ideal to put a check-valve on the oil cooler return line, but, the oil filter should prevent oil from flowing backwards toward the sump when the accusump releases it.
I got an electric valve and wired it to a switch so that the accusump doesn't do anything on the street. My only issue is that if I use the accusump to build oil pressure prior to cranking then the dme throws a code (again it's N55) and puts the oil pump into a fail-safe mode that sends excessive oil to the engine. Hopefully there is a way to tune that check out. Otherwise, it works as advertised. Getting the oil level right was a bit tricky. I ended up overfilled a few times which caused some issues.
Definitely checked the leakdown on the air side for SEVERAL days to ensure there is absolutely NO leakage. If you lose pressure on the air side the accumulator won't work.
I don't think their are any starvation issues with our pan design for accel in either direction. Also starvation is mainly an issue which happens on r comp and long high g turns.
I considered it, but ended up with a baffled oil pan. In fact, the one developed for my car (by RRT Racing) was then used by VAC as a prototype for their design.
Been looking into a baffled pan since mine has to come off for gasket change. Any thoughts on the VAC vs Bimmerworld baffles?
