what diff weight??

[mk351e]

forgot to ask this before, but my muggy tires balloon like MAD! what weight should I use in the center diff? I'm at 10K right now.

This is something Iv'e been farting around with all summer...they say run around 10-20k in the center diffs but that's just not working for me at all so I went to 50k which was better but sucked for bashing. Under hard exelleration the front end comes up and my front tires turn into frizbees! Anyway I'm now running ofna 120,000 weight in my centers and it works nice. I have some 500.000 weight kyosho I'm wanting to try! For your muggy buy some ofna 120k bro you'll like it.

Depends a lot on the vehicle. I know the OP is asking about centre diff weight, but for an example about how much it can vary - in my old savage I used to run 100k or 300k, but in my buggy (basically the same diffs) I run between 3 and 10k depending on the environment.

I think it basically comes down to diff ratio, input torque, and the rotation inertia of whatever is connected to the diff output (ie, size of wheels)

If ALL your tires balloon like mad at the same time, changing the centre diff oil won't do a thing - not much you can do here short of strapping the tyres.

If its just your front wheels are ballooning when you take off, then you need to go heavier in the centre.

If its just one side that is panning, then you need to change the front/rear diff weight, and possibly the centre too.

Note that a lot of people have recommended diff weights for various vehicles we convert, and theyre normally talking about running nitro. Electric motors have about a billion times more torque from zero rpm, and thus to are much more prone to give the diff a workout - basically means either go heavier oil (and sacrifice some of the action of the diff), or go easier on the throttle.

In general (assuming 4wd) you want heaviest in the front, and the more traction you have, the tighter/higher weight diff oil you would normally want to use. If your diffs are unloading too easily (ie one tyre is ballooning when the weight is shifted from it) then you should up the oil weight.

Ive never raced in my life..I live in alaska and theres nothing like that up here. The closest thing I have to racing up here is chasing drunk eskimos up and down main street on my snomachine. Anyway it seems like the diff oils go up to 50k then after that its 100k.

I bash with 300k in everything I own buggies truggies monsters, my inferno gt has 500k which is almost locking her right up. Get a few bottles and start playing around (by bottles I mean diff fluid...lol).

I have a Mugen MBX-5 and an MBX-5T. I use 30k in the center 7k in the front and 5k in the rear of both vehicles.

I seems to work well. YMMV
