For you mbx-5T owners....what diff fluid are you using

[magman]

I am targeting the Mugen owners specifically as I recently bought a Mugen truggy.

I am thinking of: 7F 15-30C 5R

I did do a truggy diff search and came up w/ alot of different set ups....so, this is why I am targeting Mugen owners

Good bad?

20-20-5
slipperential in center
for very aggressive driving style

used to run 7-17-3 - not bad either

[magman]

I am only basing w/no sliperential...so your second set up would be good?

[wallot]

for bashing go with thicker diffs so 20-20-5 will work well

Excellent...thanks!

just dont forget that oil won't last forever so you need to check it/replace it every few hours of runtime :)

Funny you should mention that....on my mbx-5 buggy, my diff fluid seems to last forever. In my friends koysho, he needs to do twice the maintenance I do....go figure

I'm gonna run 5K in the center for racing. Not sure on the front and rear yet.

[magman]

5 in the center seems a tad light to me even for racing, but, seeing as I an new to truggies, I could be wrong

[gtxracer]

I saw another guy running 5K in the center. I thought the same thing...but I guess I won't know til I try

I might go 10K just because I don't have a clutch and it's direct drive. Hmmm...

I know that buggies/truggies are different, but before running BL in my mbx-5, I was running 7k in the center....after the conversion, I went up to 15 and it was perfect. I was thinking along the same lines for the truggies.

[gtxracer]

Then I'm slapping in 10K for now. I think that's the highest I got at the moment. Need to stock up on MOAR.

what are the pros and cons of
a-heavier oil in the center
b-lighter oil in the rear
c-heavier oil in the front?

i am ballooning my front tires pretty badly and find my 5t doesnt turn in very well.

DIFF OIL
THICKNESS CHARACTERISTICS
Front
Thinner
• Increases steering into corners (off-power)
• If oil is too thin the steering may become inconsistent,
especially it can lose forward traction (and steering)
during acceleration out of corners
Thicker
• Increases stability into corners during braking
• Increases steering on-power at corner exit
Center
Thinner
• Front wheels unload more during acceleration
• Decreases on-power steering (reduces oversteer)
• Easier to drive on rough tracks
• If a high-power engine is used you could waste too
much power and sometime “cook” the oil in the center
differential because it “overloads”
• More off-power steering
Thicker
• More all-wheel drive effect
• Better acceleration
• Increases on-power steering (reduces understeer)
• Better suited on high-bite, smooth tracks
• Car can be more nervous to drive especially if a high
power engine is used - you might need to be smooth on
the throttle
Rear
Thinner
• Increases cornering traction
• Increases steering into corner
Thicker
• Decreases rear traction while cornering
• Reduces wheelspin

That is a great explination and should be posted as a sticky somewhere!
