N54 Baffled Sump/Pan - Accusump - Oil Pressure

So one of the issues I do NOT want to run in to on the track is oil starvation. I have seen a few other people in 1 and 3 series havving low pressure spots on hot days on track.

So when i get around to getting slicks later and use them in the summer dont want to have to revisit something like this. I'd rather over engineer and never run in to the issue than under engineer and always have it in the back of my mind.

So to combat that from now during the cooling overhaul looking for pressure solutions.

Options:

1. Considered a baffle but seen a few horror stories from E9X uses with their baffles as well as crafmanship on other engine componenets.

2. Have also found a solution by williams performance but cant see or find anyone who has used it online to see how its worked for them

3. Could try the dry sump route but not looked heavily in to it and assume costs would be rather high.

4. Electronic sensor (oil pressure based) accusump configuration but the idea of mounting that huge canister puts me off.

Bonus item:
Regardless of which route i go for i want to get an oil pressure sensor in to get actual readings.
From what i know as well i dont think we have an actual oil pressure sensor on the motor but just something to indicate high or low pressure. so will be installing something probably further up near the thermostat like an AEM sensor or something to wire in with the AIM dash later on possibly.

I think I would start with a new oil pump before doing anything else.

Haven't had any oil pressure issues yet so think the pump is fine for now I'm just trying to make sure under high Gs on track there isn't any issues.

Plus once I install a oil pressure sensor and wire it up will help identify it before it goes down the pan. :D
 
So currently there doesnt seem to be any solutions i can find on the market beyond Accusump to solve hard braking on left corners low oil pressure issues.


-Oil pressure during high G's solution?

NO Baffled sump:
None of the baffle setups seemed to of resolved the issues for hard braking on left turns this was on slicks and even cup2's, detailed thread here:

YES Accupump Chosen to go with 3 QRT Accusum ECP 55-60PSI - Ordered
Electronic if I did choose this route but dont fancy it due to the size, however have seen installs in boots and other areas which wont be as bad.
Install location to be confirmed however will not be in engine bay regardless.
Found an amazing deal on ebay from the US.

NO Dry sump
Havent seen any setups yet anywhere to be honest not that I've checked in depth.. but this may end up being the solution.


The reason i went with Accusump in the end was the more reading i did on high end builds the clearer it became that was the only solution up to the task beyond a dry sump which i couldnt find for the N54 anywhere which actually had proven results. Every other solution and baffle had no stats and only claims. Users who had the items and di hard tracks all had issues or ended up with blown engines which is not the route i want to go... so Accusump it is.

I've also ordered the ECP which is an electronic valve system so once the pressure in the lines drop below 55-60 psi it kicks in to support and i will be wiring in a master switch in the cabin as well so its only on during track days and which is only where i'll really be pushing any real forces through the car.
