Diff Coolers

martin82 · 12-11-2013, 01:17 PM

actually I would not run a fuel cell either unless its a dedicated track car with a fully enclosed system also. Would be a lot easier to fix the fuel starve with a simple bolt on fuel cell in the trunk but like I said, I just dont like the idea of having any type of fuel/oil/lines, etc as much as possible as my car is not a dedicated track car.

Dumb question possibly ?

Since I cooked my oil last time at the track, it pissed out the tube and I got blow back all over the car and Im sure some on the track. Do I still need a catch can just in case the fluid expands or overheats that much or will the diff cooler negate needing a catch can.

Also, what about heat bleed over from the exhaust. Im running test pipes and my exhaust is hot as #@!!. Should I think about wrapping the pipes ??

You boiled over your diff oil out the breather and onto the track? That sounds over filled to me.

For those that are going with the Tilton oil pump, watch out which one you are getting.
the cheapest one are designed for intermittent use ONLY
which are the 40-524 & 40-525.

IMO a thermal switch should be used with those 2 type if you want to be on the safe side
I went with the 40-527 and ofcourse that thermal switch even if its not required.

Edit, what a second, now the PDF file on all of them has changed! Wtf! Seems they redid the PDF file because everything was wrong, I hope. Now I guess you're right Megan. Weights are switched too.

524 is intermittent and 5.5lbs 1-2hr, 15 min cool down
525 is continuous and 3.5lbs 1000hr continuous

In regards to the overfill, It was a very reputable shop that did the work on the diff . I don't believe so (Sometimes **** happens)

It was probably 105 air temperature 125 degrees at track temperature along with my hot *** exhaust and me driving the crap out of the car. I posted a video of that track day. May be someone can enlighten me.

Anyway, I pulled off track and drove an hour and a half on a Saturday, they drained the fluid, added a 3 foot breather tube in case I cooked the oil, put in a different fluid and it seemed to work. Now that I have the time, I want to get all of my cooling issues in order so that I don't have to worry so much about the warmer days.

Also, from what I can remember, there are quite a few people that have boiled over their fluid while racing and had the same problem. The worst is the cleanup and even after driving it, you have to wait about 2 months for the stuff to burn off.
