Anyone use the CSF upgraded oil cooler?

On track i would assume the dct temp would stay around 205 the entire time as it is much more strenuous than the canyons.

Can't really determine much of anything from that log. Looks like over time DCT temps are warmed up to match coolant temps (200f in your logs). That's about all I see. Doesn't seem like DCT is adding any stress to the radiator, but we'd need to see a log from a track day to see if DCT temps eventually surpass coolant temps which would then cause coolant and oil to rise more quickly.

Shouldn't be too hard to find the weak link if more people post up data.

All that looks like is a stock sized oil cooler that CSF sells as a retrofit for a dedicated DCT cooler (to be mounted on the driver side). I don't see how this would provide any upgrade at all over a stock oil cooler if that's how you are using it...

Yup I was skeptical as well before purchasing. It's billed as a high performance drop in replacement oil cooler (i.e. passenger side). FWIW CSF claims it's an upgrade.

Does anyone make anything for the driver's side? I was thinking about getting a PPK radiator and associated plastic bits and fabing up a second oil cooler on that side. Not sure if I'd want to run them in parallel or series though. I know there are larger aftermarket coolers out there, but I'd like it to look as stock as possible.

Evolution Raceworks makes a dual setup I know.

Even the single ER cooler is much bigger then stock. It holds something like 2.3L of oil vs stock 0.5L. on top of that it has probably twice the frontal surface area. Single ER cooler in the stock location with the shroud should be a significant improvement.

I have this and it solved the overheating at the track issue for me.

Thanks for the results on the ER setup guys good to know. I have also heard good things about the Stett setup as well.

Thanks for the information. I see you reach 300ºf in the track and even more.

At what point do i need to get worried about my oil temperature in the track?
When i reach 280ºf i panic and start making the coolant lap.

I also have a n55 dct

You must drive it hard on track like I do

Here is the table in the DME that goes into a torque limit protection scheme if the water or oil temps get too hot:



Essentially what BMW says here is "under 117*C (242.6*F) water temps and under 145*C (293*F) oil temps there is no temp protection active"

Honestly that seems pretty hot for both values. I also tend to back off a bit once I get noticeably over 280. I once tried to run past it to see what happens and the car started to slowly pull it back and at one point I actually felt what I thought was a harder cut in the middle of accelerating... I actually caught it on video.

Good thread. I've been wondering what provides a good solution. More oil better for sure.

This is a larger drop in cooler. I think its about $1,100. us$ https://www.do88.se/en/artiklar/bmw-...er-racing.html

I wouldn't call it a drop in just yet. I emailed them a couple of years ago and they could not confirm fitment on a 1er because they never tried to install it in one. The connections will work, but not sure on if there is enough space for the core. If you get it, please post back and tell us if it fits.

Resurrection...

I wanted to see if anyone has installed the CSF 8042 oil cooler. I read the review that berns left when he had it installed on his 335i. I emailed CSF asking about the fitment for 135i's and was told there is a slight difference and it would not install. Curious if anyone with a 135i has installed it and if so how were the results and what they had to modify to make it install. I figure this combined with my CSF radiator should for for my needs.

I did it on my 335i with N54. There are better options out there.https://www.e90post.com/forums/showt...&highlight=csf

Thanks for the reviews!

Worried about tracking my N55, guess I'll have to just see how it does at a TT event and go from there. CSF radiator is #1 on my list of performance mods once I get to know the car.

Too bad the oil cooler is kinda shit, they have a slightly nicer looking one for the F series cars but I guess that won't fit our E chassis.
