N54 On Track Oil Starvation? Nexsys Oil Pressure Sensor Tested w/335i Track Car

Real Time Oil Pressure Data Recorded and Overlaid on Track Video at Big Willow. New PB with the 335 of 1:33.78. With ambient temp in the low 80 it was not much of the test for the cooling mods. The ducting forcing air through the intercooler seemed to help keep the IATs down. The newly installed 850w fan may have helped with the IAT also as it covers the back of the intercooler.

Looks like it was holding oil pressure pretty well, occasional dip on a big left hand turn.

[@DailyDriverTracking]

Yeah I'm glad! I didn't want to add aftermarket baffles or anything unless I needed to.

awesome videos! what do you use to pull the telemetry and then overlay with the videos (two questions I guess)... I'm tracking at stock power but using MHD to monitor and I do have the nexsys oil pressure sensor. Are you pulling telemetry independently then merging with footage ?

[@DailyDriverTracking]

Yes that's right. I save data from the Race Chrono phone app and combine the data with the MHD log data using HP Tuners Race Render Software. Thanks for your interest!

I installed AAF oil pan baffle in my pan. I’d say it helped quite a bit.

Thanks for your review!

Track looks nice with the repave. Did the bumpiness improve? Your BMW BP is the same as my PB, to the sub-second 🙂 Looking forward to try it out with the latest mods.

[@DailyDriverTracking]

Seems like they ground down some sharp bumps, filled and repaved over the cracks. The large dips in and after turn 8 are still there. Running without the front swaybar this time eliminated understeer around turn 2 but I was bottoming on the large dips going around 8 which made be back off some. Some of the guys that were running there said their time improved about 2 seconds.

This engine has this "characteristic". As you can see, it only drops greatly in left-hand turns. From what I've heard, you can overfill the oil a bit (1/4L, more than that is a bit dangerous), Accusump or a baffle in your oil pan. But to be honest yours doesn't go down that bad compared to what I've seen. Have you already done any of these mods?

[@DailyDriverTracking]

Yes it seems to drop a bit on left turns. My oil system is stock. Thanks for comment and your interest.

@@DailyDriverTracking I'm still yet to try my N54 (135i) at the track, I'm a bit scared to find out that by myself ahah You've got the NEXSYS sensor kit right?

[@DailyDriverTracking]

@@FactionGreen Yes I have the Nexsys kit for the MHD custom tune. So far no major problems with the crank or rod bearings. Blew one set of turbos and lost a waste gate disc on another set of turbos. I'm on my third set of turbos and second set of pistons. Everything else is holding together tho.

[@FactionGreen]

@@DailyDriverTracking Wondering if you've got any accusump system or something like that. Took my car to the track 2 weeks ago and I was seeing a lot of dips during hard-braking zones and specifically if I was braking hard and turning left afterwards. I kept seeing it coming down to as low as 30psi and I got a bit scared to be honest ahah As you might have seen on some forums, there's a lot of people complaining about the same and I'm just looking at your video and wondering "did this guy get an upgraded oil pan from the factory or what?" 🤣

[@DailyDriverTracking]

@@FactionGreen My oil pan and sump are stock. Don't really have an explanation for why my oil pressure is not affected that much by the gforces. I do have three oil cooler inline. When I drain everything the car takes about 10qts.
