center torsen diff in short wheelbase truggy
 
Hi there.

I run a GS SUT Pro and have set up the diffs Torsen, 10000, grease only.

I tried the GS team setup (10000, 30000, 3000) but the car tended to fishtail on loose gravel. With the new setup this is much better and I like the front torsen because when taking a sharp turn, it transfers most of the torque to the OUTSIDE front wheel which has most traction, and I can turn sharper and faster.

Now I have been offered a center torsen.

Both are Fioroni Storm Traction. I have read they which diff up to 75:25 in favor of the side with most traction, not just 50:50 like other torsens.

Please discuss the benefits of a torsen in the cebter position. When accelerating hard, the weight will go to the rear, thus the rear axis will have more traction, and the center torsen will transfer most of the torque there - won't I start fishtailing again?

We all want maximum traction, but not at the cost of stability. The short wheelbase SUT is a little on the instable side when going very fast. I am about to put in a high torque Picco .27 and don't want the car to wheelie or the front tires to balloon like crazy.


I used to run without a spoiler but installed one yesterday. This will stabilize the rear a little bit I hope.

I am afraid I can't help directly as I have never used a torsen, I did however, find this thread in the buggy section which may be of some assistance. http://www.rcuniverse.com/forum/m_33...tm.htm#3357491

Thanks for the informative link, Scouser.

I think it has its reasons that most GS STorm Buggy pilots advised me to use a trosen only in front. With my .27 and a center torsen I think I'd get a nervous rear axis and the car would wheelie a lot, which is what I don't want. I will stick to my current diff setup, maybe will have to experiment with a thicker center diff oil with the .27 in case the front tires balloon or spin like crazy.

Thank you.
