Default center diff question for ve8

I have a ve8 with a castle 2200kv on 4s. The question is what weight diff lube should I use in the center diff?

Depending on if you are racing or bashing...

Bashing around 30 - 50K

Racing really depends on track and setup, but with a 4s setup you will have a lot of power being put on the drive line, I would suggest 10 - 20K

Good Luck!

most people are running 5k i believe, but like jfuel said the 2200 puts out a lot of power, I am thinking of switching to a thinker oil like 7k.

I'm using the stock 5k in mine and so far I like the way it handles. My best suggestion is to try different viscosities and see which one suits your driving style the best.

I would start at a minimum of 10K, I have found on my electric buggy that it has so much power and rear bit, that it tends to unload the front end and ballon the front tires easily, this will lead to increased wear on the front driveline and center shafts especially.

Just my 2 cents worth.

I've got mine setup with the stock 5K. I don't notice the front tires ballooning too much when I blast down the straights.

Isn't the Ve8 different than your average buggy though since there's more weight up front?

You may be correct, as I do not have that specific buggy.

7k works great in the center diff.

30K??? That's Truggy wt. Nobody uses that heavy a weight for diff fluid on 1/8 buggy, for racing. The appropriate range is 1K to 10K. Most go with 5K - 7K in the center.

I'm running 5-7-2. It works great but get some ballooning with the front tires. What happens if I go up to 10 with the center diff? 5-10-2 or 7-10-3?

Default thanks

thanks for all the replies.
I will be racing. I do get "ballooning" in the front so I guess I'll take it up to 10wt and try that. I was also thinking of going with a 5s set up and tuning the esc down. this might be a little easier on the car. thoughts?

I always thought some "ballooning" is normal. I don't know anyone who goes above 7K. Most people use 4-7k, depending on their driving style.
