Oil Coolers

Hi Iím considering oil cooler option as Iím moving to a 92mm pulley.
When searching posts I couldnít get a clear answer and some posts are quite old.
Whatís the best option?:

- delete under plenum heat exchanger
- delete under plenum heat exchanger and use an additional oil cooler (with gulf oil filter housing etc.)
- keep under plenum heat exchanger and add an additional oil cooler

Thanks

My opinion is number 2 but modified.

HE delete, with CSF radiator with oil cooler combo or RK oil cooler with CFS radiator. The aluminum radiator helps. In my experience, the car runs anywhere from 10-15 degrees cooler pending on outside temps.

Deleting the HE will imply that it will take longer for your car to warm up, but I think the benefits outweigh the cons. At least for me. Also it’s not just install oil cooler and call it a day. A well designed shrout will increase efficiency of the oil cooler.

Also, initially installing the oil cooler in front of the bottom grill sounds logical, but it’s not optimal. Look at the Dinan design, e60 and F10 design. They have something in common when it comes to the location of the oil cooler.

I would also say #2. I did not bother removing the HE, but I would if I had reason to pull things apart.

I have Setrab oil cooler mounted behind the grill, gulf oil filter housing, and Zionsville (stock size) aluminum radiator. No track work to date.

Regards,
Jerry
