Can oil get too cold?
 

Ive been thinking about going FMOC on my FB, and I couldnt come up with a reason why I couldnt get a tranny cooler out of a big truck or something and have a huge oil cooler. But is there a point where the oil can be TOO cold? So the car will never warm up?

Yes. Oil needs to reach a certain temperature to work correctly. Oil is much thicker at lower temperatures and may not flow correctly and lubricate everything it is kept too cool. There is also a pressure drop with any type of cooler. Your oil pump may be working harder to maintain proper pressure. I think that if you were goign for a very hardcore racing application or were relying more heavily on the oil for cooling that you could use such a setup with a thinner oil.

In short, oil can be too cold and it is too vital to your engine to go trying un-needed new solutions. Use the stuff off the shelf and innovate elsewhere.

ouch. Shotdown. Alright, Ill curb my imagination. Bastards. lol

Hehe. Ok heres an alternative for you to explore:

I'm seeing a lot of radiators with built in transmission coolers. If you have a manual transmission could the automotive transmission cooler be used in place of an FMOC or in conjunction with the beehive cooler? For manual transmission cars its just extra weight, can it be put to use?

i wouldn't toss the idea.
i'm putting another one on my fc.
since i've got a front mount, i'm going to put that open area to work again.

Did the auto FBs have tranny coolers in the bottom? Cuase I know where an auto FB and an auto SA are sitting, and Im sure I could snag a radiator for cheap.

I believe they did. It will be obvious if they did, there will be two transmission fluid lines leading into the radiator.

Be sure to post pictures and let us know what the results are as far as temperature, oil pressure, etc.

And the oil wont be too thick to pass through the tranny cooler as fast as it needs to, right?

i'd be careful with using a radiator for oil cooling purposes. they're not incredibly strong, so with 60-80-100 (or however much oil pressure you use), i wonder if it would spring an internal leak before long.

i'm not saying don't try it, but i'd keep that in mind.
