no oil cooler n54 temps vs with oil cooler - BMW 3-Series (E90 E92) Forum

e90328i · 05-02-2012, 01:54 PM

I average around 230-240 degrees when driving more then 20-30 minutes sometimes itll never go past 210-220 if its cold out or somewhat short drive.
When going up the canyons driving pretty hard ill reach 260-270 degrees, if I get a retrofitted oil cooler would these temps drop substantially?

Also was wondering if an intercooler upgrade would be better to get first then a retrofit oil cooler kit, in other words im just looking for what would reduce oil temps the most as i believe the high temps of this engine causes certain parts to fail sooner. (friends n55 temps never really go past 245 even with hard driving)

didnt see it stated, but i take it, you do not have an oil cooler...with stock cooler on a hot day driving the car hard I have never seen over 255

07 sports pkg no oil cooler

im also trying to know temps of those who don't have the oil cooler that push it from time to time.

Consider that, with an oil cooler, the thermostat tries to keep the oil between 240-250 degrees. If you bypass the thermostat, the oil temps take too long to rise and that is even worse.

This was a known problem when the 335i was initially launched. N54 runs real hot & even with the factory oil cooler, some people get their temps up real high (people who live in "hot" states & people who put their cars on a track/drag strip). I'm in NJ & usually average 240-250, which is fine for right now but even I'm a little concerned about aggressive driving in the middle of July. An oil cooler isn't a priority, but I'm planning on eventually going with this one (after I decide what body kit I wanna go with)

I have an N55 loaner right now, and yesterday it was at 250 all day. I wasn't even driving it that hard. It didn't have a oil cooler, FYI.

Get a Strett, you will see daily dr en temps in 90+ degrees with FBO OF 210-220 and 225-230 if driving it very hard.

There are tests here with a Strett vs a oem.

Hope it is aloud to post links, if not I apologize.

I have a Strett on order after seeing my buddies temps I listed above....getting on it I would see 260-270 with the exact car as yours.

robc, quoted you in another thread so I'm sorry to do it again -- where'd you order your STETT oil cooler??

No problem, I ordered it directly from Stett....best mod I have ever done. I modified my inner fender also (may post a vid of this). Make sure you have the vented fender.

I have the OEM oil cooler already, but I'm looking to upgrade since my temps are already around 250 on just a tune and intake (so I'm concerned when I bolt on everything sitting in my basement). W/ the Stage 2, where are you normal/daily driving temps at?

They are 200 if that in 96 degree hit...220 tops if heavy racing over & over...does a great job!

E90Company · 05-31-2012, 03:53 PM

I have an oil cooler, and in South Florida driving lightly around town for 40 minutes gets to 248

Jeff@TopGearSolutions · 05-31-2012, 03:58 PM

Well 270 is limp mode if I recall.

Normal Oil cooled cars on this platform are 245 (give or take 10 fully warmed up). Thermostat is partially open at some point and fully open near ~238 approx.

Non oil cooled cars can exceed 260 fairly easily depending on conditions and how far they are pushed.

Some non oil cooled cars can get BMW to warranty a conversion if they hit limp mode enough (depends on dealer).

**

Evolution racewerks has a conversion kit for non oil cooled cars and an upgrade option along with it. (on my site). I would definitely recommend it for any non oil cooled cars.

So even with aggressive street driving, you're in the 200-210 area

OEM or aftermarket oil cooler?

Sounds like we just need one more piece of info: What is the OPTIMAL oil temp for the N54?

If it's between 230-240, then go with an oil cooler kit that doesn't change the OEM Oil Thermostat: Evolution Racewerks, VK Motorwerks, AR Design, Setrab/Mishimoto DIY
If it's between 180-230, then the STETT oil cooler kit is the best one since you have the option to delete/use a 180F oil cooler thermostat

PR3CI5N · 05-31-2012, 06:03 PM

My 2010 E90 M 335i never goes above 255 even when railing my car. Drag race after drag race or up a canyon. My 07' 335i w/o an oil cooler would hit 260+. So having an oil cooler def helps.

PR3CI5N · 05-31-2012, 06:04 PM

When driving around town I'd say around 240. When railing, should be around 255 with an oil cooler.

Aggressive street driving/racing the highest I have seen is 220....I also run with my cowl off snd tht also helps. My fender also has a lot more than stock ventilation .....doubt that matters to much!

A OEM oil cooler, Stett stage 2 or 1 would be much cooler.
