Appropriate temp range for Slipperential?
 

Just like the title says, what is a reasonable temp range for the Slipperential to get to by the end of a run? Or to put it this way, what temperatures can silicone oil withstand before breaking down?

I feel like my Slipperentials are getting a bit hot (hottest was 200F) at the end of a run. This is with relatively thick oil and medium to tight slipper settings. No excessive slip or unloading.

I think the temp of the slipper wouldn't matter as long as your motor's & ESC's fine. Just make sure u do regular maintenance of the slipper and change difffluid if needed. The slipper spur rubs directly on the pinion which both are actually steel rubbing against steel so high temps are normal. :)
Just my opinion.

200* is pretty hot for the diff bearings and may transfer to the motor. IMHO.

The diff fluid will tolerate way hotter. 400+ degrees. It's the shear that breaks it down.

I'd agree with above, really high temps will be tougher on the bearings and slipper pads. I'd guess 200* would still be acceptable on the faces of the slipper back plate.

The slipper pads are made from Ferodo material which can withstand very high temps. Rubber seals on bearings, not so sure? Haven't noticed any issues yet, but my buggy is due for a teardown/rebuild so I will inspect the fluid, pads, bearings then. Might switch over to the hardened steel endcaps to try them out.

I melted my Teflon pads last race, the screws were loose n caused the slip diff to slip too much n smoke came out of the diff, I thought my car was burning. The diff was not damaged at all! It's good stuff. Although The Teflon pad was burnt to a thin black patch.
