Official Erevo 1/8 scale center diff thread

I've seen quite a few people mention the torsen diffs dont handle BL power all that well, plus they work the opposite way to a normal diff; instead of sending excess power to the fronts to prevent wheelies, they send all the power to the rear wheels (if used as a center diff)- not good for handling...

have thouse people tired them?

i have torsen diffs in 3 of my brushless conversions (2 buggys and a truggy)and all of them show very little wear

i think the people who are haveing problems are either building them wrong or not changeing out grease often enuff

and as for putting power thrugh them, im running 5 and 6 cell, when set up right they work the way they should, my 8ight will lift the wheels about 2 inches for only a second when leaveing the line but its a hell of alot faster launch than balloning the front tires.

Torsens dont work that way, a torsen diff has the ability to bias the torque without any slipage. It can bias up to 3 times more torque to one axle than the other.

On acceleration it will send up to 3 times more torque to the rear. After that ammount the front will start to slip (or lift!) and If an axle is on the air it can transmit any torque and 0*3 = 0. In theory is impossible to pop a wheelie with a center torsen..

A viscous differential will send equal torque to both axles until one loses traction, at that point it will start to send power to the axle with more grip according to the viscosity of the fluid and the difference of speed... And it will do so on and off power, while torsen in off-power acts as an open diff, improving both on and off power turning...


If the available torsens can stand the torque of a MMM they will be ideal!!!
