Geared diff

[northernmonkey]

to go geared or not? Or keep running the ball diff?

You might not like it, there more of a outdoor thing. If i ran one, and to be honest i am thinking about giving one a blast you'd need 1500cst oil at the very least.

Deans new car had one in on friday when i looked around it, the oil was far too thin causing the car to rotate rather well!

You need plenty of grip to make one work well, 1000cst is a good start.

I was running 50wt silicone shock oil at one point, but at donny with the lower grip..hitting the power onto the straight was forcing the car to diff out and rip one wheel up. Pushing the car all over and onto the infield the majority of the time.
I've tried 2000cst at Donny and its seems to make the car want to push quite alot into corners. 1000cst seems to yeild the best results, but until the grip picks up they can be a little sketchy.

I would say unless ur fed up of rebuilding the ball diff, or planning on running out doors. I would keep the ball diff in. Smoother and less likely to bite you in the arse. As the geared diff effects on and off power steering. In the sense that you can turn into a corner, squirt the power on and make the rear rotate.

Top advise guys. I'll get my sand paper out then.

Ball diff all the way indoors. If you do want to give a gear diff a try indoors I'd do as Larry says and go for 1500cst. I'm contemplating giving it another try indoors, but it would only be with thicker oil.

Why not run the gear diff dry? are they nylon gears inside?

[neil]

would probably handle like a bag of spanners. Oil helps to keep the minimum backlash in the gears at a guess, along with lubricating properties.

Too loose aswell, Especially after battering it around abit. Cant have that, has to be a nice tight one.

Tight is good, loose is bad........

And when talking about gear diffs if its too loose all it does is diff out and give you way too much steering/rotation.

my gear diff was really loose on Friday and car was very difficult to drive.
Decided to open it and check the oil but it was empty.
Wonder why it drove like poop!!!
Re-filled now with 2000 cst (which andy moore recommended to scott w)so hopefully will be a lot better next week.

Good work Deno, that should be elephant dunk loads better mate

Geared diff re-built with 50 shock oil (650cst). There's quite a few in use at Ardent, 70 shock oil seems to be the fluid of choice. With less grip at Donny a thinner blend was suggested. We'll see...................
