Anyone ever heard of a switchable EOC?

It would either be controlled by a manual switch mounted in the cabin, or, ideally, it would tap into the existing oil temperature sensor and automatically engage when the oil temp hits 225-230 and automatically disengage when it hits 210-215.

I want to run cooler at the track, but not at the expense of running too cool on the street. I just want the oil to operate within a narrow temperature range, like the coolant does.

The idea is very simple in concept - has anyone ever heard of it actually being done? Are there any hurdles to overcome in order to turn this idea into a real system?

Thanks.

They make mechanical thermostat control valves, I think I even have one in the garage that came with a oil cooler I was going install on a previous car (ended up using it to fix my GF's transmission cooler that was integrated into the AC condenser...).

Here's on example:

I wouldn't over-complicate it with a lot of electronics. Do a search for oil thermostat and you will find several options.

OK, right. So the engine cooling system would work exactly the same way that the water cooling system currently does. That sounds pretty good; I do like the idea of eliminating electronics when possible.


Any other feedback?

I bought a Ron Davis 4-core radiator for mine, and got a unit designed for an automatic vehicle.

I put a Canton sandwich adapter between the filter & block and plumbed it in.

My oil temps stay pretty much around 180 under normal conditions and -15 to -20 degrees of coolant temps when at the track.

Seems like you are trying to over-complicate it with a thermostatic valve, etc. Apply the K.I.S.S. principle to it (Keep It Simple Stupid)...

i use this thermostat/plate adapter:

Instead of oil to air cooler with a thermostat you can use an oil to water cooler.

These are the parts I put into my 2006 C6 for combined street and track use:

Thanks all for the suggestions. I like this remote oil thermostat:

http://www.summitracing.com/parts/CTR-22-480/

It doesn't switch until 215 deg F, which will allow the oil to reach full operating temp when I'm just puttering around town.

Thanks again everyone for the replies. I'll probably go with that Canton 215 tstat and the DeWitts radiator with integrated EOC.

One final question: Should the stock oil pump be ported or upgraded to effectively move oil through an aftermarket cooler, or is the stock pressure sufficient? Or, I guess another way of asking the question is - Will there be a decrease in oil pressure after installing a EOC?

Thanks in advance.

Hey Mike,

For my 02 C5Z I went with the DRM Track Kit (Setrab 40 row cooler). For the street I just wrap the front of the cooler in aluminum foil and that get me 185 degree + temps, while on track i remove the foil and have not seen above 245 during 100 degree temps.

Not too sophisticated but effective.

Summit used to have a B&M Thermostatic Bypass Valve that sold for less than $100. I used it with the Engine Oil Cooler that I had on my C5Z. It would run 15 % of the oil through the cooler until the oil temp hit 180 degrees and then it would switch to run 85% of the oil through the cooler. This permitted oil flow through both circuits all the time and eliminated the chance of getting an air bubble in the line that a regular thermostat would close off. The part looked like a big H. Plumbing it in did cause a plumbing nightmare to get the thing mounted so it worked properly in conjunction with a remote oil filter. Without the remote filter it would have been a piece of cake.

Yeah, I remember you mentioning the aluminum foil thing at a GTG months ago. I'm gonna try for a more elegant solution... but unfortunately elegance = $
