Differential cooler

I'll say the same thing I tell the BMW people - get an actual oil temp gauge,a nd put a temp sensor in the drain plug location. Watch oil temp. If it's taking forever for it toe ven get up to temp - you've got too much cooling. If it's overheating in enduro/race conditions, then maybe either a finned cover, or get an overflow bottle and let it purge into the overflow bottle, and still watch temp. I've got a nice email from Redline tech support stating that a majority of track people overcool their fluid and do more long-term damage by not getting it up to temp quick enough than the few who have actual temp problems.

Temperature sensitive stickers. They change color when they reach the temperature marked on the sticker. Last time i bought them they were around 20 euros for a booklet of ten, and the scales go at least up to 300 degrees celsius.

You could just slap it on the cover, drive around and check what temperature was reached.

The ones i had were oil proof, so if you're really interested, you could slap one on the carrier itself too, and see what temperature it gets up to.
 
I'll check into the temp stickers. Sounds like the most economical way for me to check the temps.

And those Grp A diff cooler pics look much like the NASCAR diff coooler set up used on 70's(and probably now too) NASCAR cars, except they used the DS to pump the fluid., towerymt. Interesting set up there.

Thanks for the pics!
 
Not yet Ken. Been busy with getting the LTAs ready for painting. I realize that diff has an operating temp. Also realize a race diff cooler would most likely be too much for street use.

One of the reasons I was wondering if my idea of a diff cooler ,might be better suited for street use, as it would cool just a little/help out under hot temps. (maybe)

Although I still need to see if there is even enough room/clearance for my idea. It is just a thought I had, and haven't had time to see if I can actually implement it. Clearance might be the biggest problem IMO, given that it'll even do any cooling.

I just thought of it when I saw the mounting bosses of the pass side of diff, were already drilled & tapped.
 
Parameters man parameters.
You need to know what you are up against before you go off tilting windmills.
I mean it's an NA 240 driven on the street..RIGHT?

Fluid temps are not a problem. Now if you just want to fashion a cooler to do it - knock yourself out. Just know that you may actually cause yourself a problem that doesn't exist now.
 
Bench racing at its finest hour. :)

But come on, with just a little effort this thread can reach 100 posts.
That is a REAL accomplishment, really. 100 posts for something that should have taken 3.

What I'm wonder is if I need a ash tray cooler in my Xratty, see?
No?
Well ciggies burn way hotter than diff oil in a n.a. street car, and ask anybody, when I smoke I do big Rasta-type tokes on the ciggies (wonder what I learned to smoke first? duh)
So I haz these orange hot ciggies and I'm sure they need cooling.

Oh the car is a turbo 2300 8v brown injectors and a slightly bigger T3 than Volvo.

Do I need a ash tray cooler?
 
They're just making sure the cars wear out so the customre comes back and buys another.

Overheated diff oil???? :wtf:


PERFECT!!! :lol:
