Quick question about them, can you rebuild them? If so how? By rebuild i mean 'retighten' them?

I believe you can, just don't know how its done.

 

i think the gear people called bara can do this for you.try contacting martin at reyland.

 

The Viscous fluid in them can be changed. Special job though.


Some guys on J44 claim there are people here that can do it. I find it hard to believe though.

 

bara motorsport will do it, i remember when i was at bara,s heshowed me the stuff used in the viscous diffs..same stuff as im silicone implants he said, it was a clear gel.

talking about silicones did get me excited though

Just something i've wondered about, i'll drop Martoon a line sometime and see what he can do

I've never heard of anyone doing it over here either Stevie. Talked to Steve Gault about it a while back and he agreed.

 

The silicone is a special one used, like you cannot find anywhere in the shops. Tons of research has been put in these silicone gels, not a job for anyone. Bara Transmission is the company to ask for that job !

 

hi mate

bara has all the rights to VC (lock stock barrel) , he can uprate any VC mits/subaru/cossie/viper basically any car that uses a Viscous Coupling and it will be done right as he has a dyno to measure the right Nm's

obvisouly with the standard plates you can only uprate them so far

heres an example a 7.5" cossie rear V.C can be done to 240Nm no problem at all with the standard plates (25Nm standard when new)

lets say if you wanted a 300 -400Nm uprated VC then plates would have to be changed for the Nickel plates which can take alot more pressure/flex alot of people go this route on the rally cars lose surface

cheers marco

 

paul give fred crawford a bell, mate of mine got his done a few years back through fred , he ll put ye right one way or the other !

 

Marco

What effect does the uprating of the diff have on a road car's behaviour - locks up more and hence more tail happy? Could you describe a little bit?

Cheers

 

hi mate

it basically locks the other wheel nearly striaght away for better handling traction there is no down side at all on the road in a rd car

there few people on here have had there rear diff uprated and they cant belive how good it works

marco

 

can anyone give a ballpark cost for this?

 

bump, keeping standard plates, just to change the fluid and increase the rate slightly?

 

Have a look here http://www.gearboxman.co.uk/psdiffsgearboxman.html

£175 for uprated diff
