Feeler: Custom Twin Oil Cooler

Background: I have an early build 335i with no oil cooler and during the summer or any hot day I've notice how high my temps go. So I figured it's time to get the oem oil cooler setup. Spending a couple hours sourcing parts, I realized going twin aftermarket was cheaper and more reliable.

I really don't want to fork out over $1300 for an ER Competition oil cooler yet alone the $700 for their basic setup, so I've started sourcing my own parts. With the build I'll be using oem filter housing and thermostat.

I've found pretty much everything they are offering except for a mounting bracket and shield. So far under $250 spent on parts ;)

I'll be fabricating my own mounts soon and fitting everything on my car.

I currently have a broken arm right now so this build will be slow. Not sure if anyone has done this yet as I'm too lazy to search.

Once everything is finalized I'll provide a list of parts and where to get them. I'll also provide blueprints for the mount or sell them.

Please don't bash my thoughts only kind words or GTFO.

3 track events and oil is still good!

Contrary to popular belief you do NOT have to change your oil after every track event.

I used to change my oil after each event but I decided to send my oil in to Blackstone Labs for an analysis. They said the oil was perfect and try doing 3 or 4 more events.

Well I did that. Below is the Oil Analysis report after 3 track events and the oil still looks good. It's only been about 3K total miles on the oil but either way, you do not need to change your oil after every event... at least for our dual purpose HPDE vehicles. :D

Here's the report:

3 track events and oil is still good!

Huge Custom Oil Cooler

In my quest to solve the dreaded limp mode which I've encountered on multiple tracks I finally decided to build my own Oil Cooler. It's sorta a copy of the Stett oil cooler but I'm using a 215 degree Improved Racing external thermostat vs the 180 degree Mocal thermostat that comes with their kit.

All in parts cost me about $900 but that's because I went with a huge 34 row Setrab oil cooler, Improved Racing External Thermostat, and very high quality industrial grade fittings and hose (long story). It could be $300-400 cheaper depending on options.

Even with the Mishimoto Radiator, I hit 270+ degree oil temps at the track. Cruising around town my oil temps were 240 degrees.

With new new oil cooler setup I'm now crusing at 215-220 oil temps! 20 degrees cooler is not too shabby. :thumsup: This, along with my vented hood will hopefully solve my cooling issues.

I have a track event next Friday Oct 9th so stay tuned for my report...

Enjoy the pics!

Tiny factory oil cooler next to the huge 34 row Setrab cooler. Can't fit anything bigger.

Crappy ebay hose... no one local sells the SS hoses or fittings that I needed so I had no choice but to buy all new industrial grade fittings and hose (very expensive but very highly quality).

New fitting and new hose. The ebay hose could be pinched with your thumb and pinky; this hose is rock solid.

Oil Cooler mounted w/ my custom made bracket. I didn't even have to touch the metal bumper bar that Stett requires to be removed.

Some extra ventilation in the fender liner. :lol:
