Diff oil query - setup for tight turn in and big oversteer

[Jahay]

Hi everyone....
From what i know and what i have read, people say that you should use lighter diff oil in the front to aid turn in, and a light diff oil in the rear.... This doesnt make much sense to me and hasnt worked....

I noticed a lot of flux owners putting heavier oil in the rear and a lot of nitro users putting heavier oil in the front...

I was thinking that when i turn in, i get a lot of understeer on fast long turns. If i had thicker oil (50,000) in the front shouldnt this help turn in as no power is lost on the inside wheel?

I also want oversteer, so would heavier oil be better for oversteer too so when turning, lost power power doesnt go to the inside wheel??? My truck was handling really nicely at one point but its been a little worse on turn ins recently.

I currently run 30k all around, but im tempted to run 50k front 30k rear, or should i just do 50k front and rear?

I originally used to run 50k rear and 30k front but wasnt sure if i liked it...

What should i do to get a sharp turn in and nice oversteer???

Thanks for that link, but i am asking for advice... I am asking what sorts of weight are more suited to a savage consindering buggys and truggys you lighter weights....

What about if i used

50k rear
50k centre - ofna spider diff, so should behave like 75k???
20k front

Should this give me really nice straight line traction as well as tight turn ins on grass.
I know my long fast turns will be killed a little by the 20k but i prefer fast, tight sliding turns...

dude, read the link. It ADVISES all the knowledge there is to be had about oil viscosity and how it affects your steering.

Do you want us to dictate it for you and then perform whatever tasks you deem necessary on your savage? Because that could be arranged

[Jahay]

wow if you can carry out a few tests for me that would be great haha...

The only reason i continue to ask is because the weights discussed in teh articles are very low weights compared to what i am used to hearing when discussing any topics with my savage...

Does this mean that i and everyone else who run 50k or 30k in our front and rear diffs are wrong? And we should ideally be running 5k rear, 7k front and 20k centre?

The difference in oil viscosity is minimal here, so if i am talking about using 50k rear and 20k front, couldnt that cause a real extreme imbalance in handling???

I want peoples genuine experiences running larger trucks, not little buggys.
What others run, how it performs in slow as well as fast turns...

I understand what is mentioned in the article completely, but if running differences of 50k and 20k,would that cause irregular handling???

moving the cd up to 50,000 will likely result in a wheelie machine.

to get better turn in, go DOWN in weight in the front diff.

the 7/10/5 setup that most racers use also works well in monster trucks. The weight difference between a truggy and MT isn't that great.

I advise lightening up

Perfect advice, just what i needed...

Looks like i need to get some new oils...

I will most probably run a very heavy weight on the front as i dont really want the cd to do its job. I would prefer to lock it up a little, so may run 30k in the cd, but will use 7 rear and 5 front!

CHEERS!

Any other advice appreciated
