Hi Neil
Bara uprates the 7" VC to 180Nm on the standard VC plates
however there are Nickle VC plates available for the 7" which will increase the Viscosity to 240Nm which is nearly 10 times more preload than standard ,the prices of the Nickle plates are more expensive tho
the 7.5" VC can be uprated to 240Nm on standard plates and 400Nm on the Nickle plates due to the actual size of the 7.5 diff it's alot bigger than the 7" unit
as for the planet gears they are uprated items that he makes himself and me being 100% honest i couldn't tell you how much torque they can handle he has fitted quite a few to rally cars and seem to last ok but i think the rally car use alot less power than your car but some of the rally cars will have more low down torque than you
Bara told me a few times now, if people are going to launch their cars time and time again then they might be better of with a plated diff or an atb something that will do away with the planet gears
you cant get a better more road freindly diff than a VC item in simple terms

Hi Mike
the 9" rear CWP 3.64 has been replaced to the 3.62 so it's compatiable with 4wd cars so it doesn't harm the center VC
im not saying 0.02 would make any differance at al to the VC but it is better off to keep the same ratios if you know what i mean

Can I bring this subject up again.
Just broke the planet gears on 2 different 7.5" diffs in less than 3 miles driving!!
with no heavy launches what so ever.
And one of these was un uprated VC and shot peened gears!
Need to find better options asap. for track use.
Marco, Thanks for the info on the plated diffs, re Kelv. But want to find out the best route to take.

Mike.
Cant seem to get hold of Rod, phone switched off and no reply from PM.
Anyone know where I can get a good 2nd hand 9" diff, preferably plated and 3.64.
What are the complications in fitting a 9" into a 7.5 rear beam??
Cheers
Dave

i was pretty convinced that the diff bolts directly into a 7.5" beam.
but i cant say the same for the drive shafts - it would be perfect if the shafts you have fit to a 9" diff, and that the Prop fits up as easily aswell.

Well if you do find a complete 9" diff i have a 3.6 CWP kit in good enough used condition available .
There are 2 Diff carriers tho , 1 upto 4.44 and one above , if you try to fit a 3.6 to a 4.44 carrier i understand there are some minor issues !

Mike.
What does Rod use?
The mustang 8.8 fits will little mods to the beam. A guy in America makes custom stubs to use standard axles. Ratios are plentiful. A spacer is easily machined to use the standard propshaft (the mustang diff is 19mm shorter). If you buy the right cover you can also easily install some lateral bars if that takes you fancy. And a diff mount lines up with the exisiting mount.

Trouble is Mike I need a quick fix at the mo, but dont want to throw money at something that wont last, just to get me out of trouble
If I cant find something by begining of next week, panic will be over and will certainly look at Rods set up or maybe the 8.8 diff

Basically I purchased a brand new diff (new ford racing cover) with choice of ratio and posi carbon plated lsd for your price approx 1kbgp Vic knows all the part numbers etc. Then a you can modify the original stubs or buy a set from a guy in US for $450us or so. Then I have a drawing and have machined an adaptor to mount to a standard prop.

hey mate, greetings from the south pacific..! where the only done up car in town has a PA speaker as the sound system... anyhoo I digress..
I have emailed the designer of the 8.8 diff mounts and asked if wanted to sell it in kit form. I'll let everyone know what he decides.

You have been waiting fucking ages for it..........
Here it is in all it's glory...... the VIC special 8.8 6 degree beam with rouse type spring changers.
50mm (Gavin your a champ) box section and 45 degree cut fit straight in
Laser cut box sections bolt into 18 degree position and weld in.
Extension on the same radius from the outside pickup point.
Extra bracing and box in for underneath section.
Not bad for our (Paul B) first attempt at a rear beam!
P.S. - Vic the colour looks great in real life and is metallic blue/grey.

The 8.8" conversion has been done on a friends car, by welding new brackets to the beam.
He uses two short Cosworth drive shafts, and modified 8.8 yokes. So far split one drive shaft and three joints.
I'm gonna try doing more of these conversions. For my own setup I have custom made yokes, which lets me use stock Cosworth shafts(both 2wd and 4wd).
I'm also working on a jig, which helps me place the 8.8" in the stock location.

I'm really surprised noone has produced a proper 8.8" conversion kit for the UK market. It seems to make the most sense as the differentials are cheap from the USA, and best of all, it's all Ford kit!
