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

In theory yes..

Your ďRK oil cooler/radiatorĒ solution should include everything you need and you donít need Golf oil filter housing.

what's up with all the hate for the stock heat exchanger? I get that it actually heats the oil during any condition where the oil temp is less than the coolant temp, but I'm not really looking to keep the oil temp lower than 200-210F anyways. Why would you? The stock heat exchanger, being a liquid-to-liquid exchanger, is efficient and I imagine that it becomes very efficient at higher delta T, for example when oil temps get up to 240F+ on track.

You should read the purpose behind this. No one is hating on the stock HE... but why read right...

I'm filing a hurt feelings report

You're talking about how the location of the stock HE radiates heat into the plenum? Extra-bad on supercharged cars. Or are you talking about another issue?

Must be a generational thing.

In this specific thread we are only discussing one question.
