After installation of the Dinan OC, the oil temp gets up to about 240 when pushing the car in warm weather, and it stays there, even in 92 degree + heat. I'm sure I could get the temp up a bit higher if I were to track the car, especially in hot weather. When cruising, I normally see about 220-230.

I have pictures of my oil cooler installation as well as an initial review somewhere around here. I've had it for over 1.5 years now.

240f on track? never pass to 250?

Why don't you try reading my post again.

I have a Oil Cooler in development which should be done within the next month. It will be amongst the best, and will perform better than the factory replacement coolers by far.

The pricing will be in the 500-600 dollar range I am hoping for the entire kit.

I miss the part between wanting the best and getting robbed to have it but it's ok

Feel free to keep me updated (also in private) about that, thanks

Biz was giving you a suggestion. Options are limited. I went with the VK oil cooler as did some of my trackmates.

Here is the review. Best is subjective, all you need is from an OC is for it to keep your oil temps down under track stress and high ambient temps. The VK OC did the job. See my review here.

Are you a vendor on here now Malek?

[uberschnell]

I think it's still the case that the VK oil cooler does not come with a shroud. Personally, I think the AR twin oil cooler is the best choice both in design and capacity.

Keep in mind a BMW OEM oil cooler kit for your car would run close to $1500. It's more then just a core. And no oil cooler on the track with an AT is guaranteed limp mode.

[Craig@SupremePower]

AR Design FTW!

[wshgrntd]

How about ER oil cooler? Which is the best?

[4doorbmwpower]

build your own custom one with a 25 row core. it will cool better than all those. and you can do it for less than 350 bucks easy.

Andras, if you search you will find an custom oil cooler retrofit job DIY I followed to add the biggest oil cooler possible to my non oil cooler '07 335i. I bought the biggest mocal oil cooler I could fit in the area behind the front right corner of the bumper with the AN fittings where I wanted them and ran AN lines from the modified oil thermostat housing (see the DIY I am referring to).

Thread is called "DIY oil cooler" posted by user Boom. Can't link to it on my IPad e90post app. This is by far the best and most cost effective way for you to add an oil cooler.

[4doorbmwpower]

the best you can BUY without going custom like most people do... is ER competition series. It is MASSIVE and utilizes both air dams in front of the tires. surface area is out of this world but you do pay for it. My 25row will provide me with more than enough cooling.

[Laurus_CEO]

I'm very surprised that the ER competition cooler wasn't mentioned sooner. the "limp mode party at the track" thread is definitely the best resource i've found for real data regarding oil cooler upgrades and tracking the n54. That thread is the primary reason I purchased the ER setup after my first track day. I actually didn't get to install it before my most recent track day but am looking forward to limp free tracking going forward. It's interesting that people in this thread are suggesting Dinan and other kits which seem to have mixed results in other threads. I've spoken with and seen other n54 cars / owners that can track with the factory oil cooler and no issues and others with upgrades that still have issues. I think there are a ton of factors, the driver, the power level (mods/tune/fuel), the track layout, AT/MT, and ambient temps all make a huge difference.

I've done quite a bit of research on the topic, seen many DIY setups, and lots of mixed reviews for how the various setups perform t doesn't seem like there is a clear cut solution to heat issues when tracking n54 at higher power levels. I know that Mshimoto has a kit in development, I lookd forward to seeing Malek's kit and some other more cost effective options become available but hopfeully my er cut does the job for me. I know some of the AT guys have been looking into upgrading the radiator and heat exchanger which wll make a big difference. I also hadn't heard of the VK Motorwerks at all before this thread but personally I would go DIY over any of the single cooler kits, simply because I think that the performance of them could be easily matched for less money. I bought the ER for a lot of reasons manly because it appeared that people with it no longer had oil temp issues and were able to run higher than stock power levels at the track. But I must admit part of me just wanted to have a "baller" setup not a diy, I also love the look of the dual coolers filling both front fog light areas and thought that I'd be getting carbon fiber shrouds (apparently there are fitment issues and these are not actually avaiable anymore which I didn't find out until my kit arrived with alum shrouds despite ordering cf) which would've matched so nicely with my hood, lip and plans for more CF in the future.

I second Evolution Racewerks as hands down being the best. I mean come on look at the pictures.

Agreed, this kit is sexy. Would be even sexier if I actually got the CF shrouds.

Only issue with er kits are that the connectors and fittings attaching to the radiator tend to leak. Do yourself a favor and put in steel lines and higher quality fittings when initially installing it. It's a very good kit and very effective at keeping temperatures down otherwise.

Are you speaking from personal experience or where are you getting/sharing this misinformation from? I have heard of no issues about the fittings leaking and if they did I would assume there must be some sort of installation error because it's pretty hard for AN connections to leak otherwise.

I have read about some issues with their lines, and general debates about nylon vs SS being best for this application, which IIRC was even addressed at one point by ER in a thread and is backed up on their website's product description for the kit touting their use of nylon as superior to SS. Conversely it's very interesting that the kit that I have came with silver SS braided lines not the aforementioned black nylon ones. Perhaps I should contact them about this.

I know some people have had issues with the supplied nylon lines coming in contact with certain parts and rubbing/wearing over time which caused a leak and people switching to SS or adding some additional padding where the contact occurs but nothing about them leaking at the connection points (none of which go to the radiator).

[DuDai]

From my own experience on my own car one of the lines completely ruptured within 2 months. As well the shop here that has installed quite a few of these kits stated at least 50% of the kits with nylon lines end up having this issue so now they will only install with steel lines. A few on this forum also have had the same issue with the sport kit:

Thanks for sharing the links/info and my bad if I came off rude in my last post, your previous post didn't seem to be based on experience. I guess it's good that I haven't installed my kit yet and can see about solving this before it becomes a problem.

My memory is terrible both of us posted in this thread lol, seems like ER has made updates (SS lines and no CF shrouds) to how they actually ship the kits but haven't updated their vendors (ordered mine through mike@n54tuning who also thought I would be getting CF shrouds) or website . They probably don't want to eat their words on all the nylon>SS stuff they have posted up despite the issues and change.

[MM Performance]

Well the ER kit looks great but adding a second oil cooler can also be done as a DIY, just 1 more line and 1 more oil cooler and another simple bracket for the drivers side. Just hookup output of first oil cooler to input of second one. I also don't like too much that the oil coolers have the input and output on the bottom. I bought my mocal cooler with input on bottom and output on 2nd end tank on top for better cooling distribution. The best part of the ER kit is the shrouds and it looks like they sell CF shrouds also. I would just buy those, looks like 150/225 for aluminum/CF shrouds for both coolers.

No problem man. I wasn't offended.
