Experts chime in: Torsen Diffs in an IGT conversion

I would probably try one in the front. It seems to me like thats where you would see the most benefit from it, and the traction load would be less than the rear. Im by no means an expert on this subject though, my only experience with this kind of diff is from full size cars. A lot of performance oriented awd full size cars run limited slip front diffs with open rears (EVO, mazdaspeed6, WRX, etc). Are you running a center diff or the 2 speed?

Take a few min and go read postings over on UE - the diff section, they've been discussed over there for both nitro and elec RCs. Offroad -no good in either, too weak. Onroad - maybe??

Is a brushless conversion without the two-speed, and that's pretty much how I see it also. Even though you come off the gas and save the drivetrain from the big hits of jumps, off-roaders frequently come off the ground in the straights, (while under heavy power) and I am quite sure that that spells disaster for the complex internals of a torsen diff. The stresses placed on a diff by an onroad car should be much less, and maybe I can get some of the performance of the cars on the road today using these type diffs. I was thinking of starting with just the center like Audi's legendary handling Quattro's have (http://www.audi.com/audi/com/en2/too...ferential.html), and maybe moving to the front and rear later.

I have read in many places, both rc and 1:1 scale. I have especially searched in foreign forums that cover rally game type cars, but nothing seems to be out there. The reason I started this thread was just for some hypothesizing specifically about an onroad application, seeing as that rally game type cars are just getting popular here in the states. One thing I do know is that later if all goes well, I will spring for some Nuova Faor or Fioroni torsens after I run through some trials with the Ofna's, but the sticker shock on them is a bit much to experiment with.
