diff advice please

[fastboy]

no

the 10k in center will make it tail happy.

drop to 5-5-2 or even 5-3-3 and try again.

[gray.g]

5K front 10K centre and 2 K rear.

this should give me more drive on all 4 wheels but also pull the front more.

that is why i would like to have maybe more over drive infront.

i have forgotten hot to work out the diff and gear ratios and think i need to read up on it again

You need to read up more on diff oils first!
10 center will give far more drive to the rear. You need lower oil for less drive at the rear.

i do but it makes no sence at all.

so from what i understand the thinker the oil is in the centre the more drive it will have to all 4 wheels.

the thiner the oil is in the rear the more it will slip / be pulled

the thicker the oil is in front the more it will under stear / pull

only what you had m8 from when i bought it from you.

I think you probably running 5-5-5 or 5-3-5 if you have not changed it.
Loads of testing and racing week in week out, I now have my RC8.2 pretty dialed!.

Are you doing the SRS at ADUR on the 5th? I will have a look at your setup there. Failing that I will probably be at Clanfield on the 19th for a run before the SRS round.

i had 5 5 5

Lsd = limited slip diff

What I was getting at is that standard diffs in the RC8 (and most buggies) are limited slip differentials.

you are half way there m8.

inside lsd there is somthing called shims depending on how you have them setup they will bite and both wheels kick in and turn at the same speed.

rc8 etc... have what you call an open diff.

the only way to get them to bite more is to have a thicker oil in it to slow everything down inside the diff or like what we do on the vw race cars on the spider we use bolts to tighten the spider gears to make it reacts as a lsd but in doing so you put a lot of strain on the teeth

Don't think you mean shims, mate.

Shims are the little washers used to eliminate play in the gear mesh. Its the viscosity of the fluid used in side the diff housing that determines the amount of power directed to each wheel. Hence them being limited slip and not open diffs, which they would be with no fluid in.

shims / clutches.

in the quaif diffs tehre are like little dome things. that fit in each other.
