Chain Driven Differentials?

[mboyd29]

Hi all,

I've just came across this forum whilst looking around for a few things, just recently started working on a kit car project idea. I've got a motorbike engine ready for the build but as I'm designing the chassis I'm still questioning a few ideas. the biggest one being the drive train. I've read a bit about chain driven differentials and was wondering if anyone has used one or would know where to get one (cheaper than some of the online prices) or if anyone has ever made their own? the other and probably easier option is to mount the engine sideways and just use a shaft rather than chain. although I'll admit I'm a fan of having the engine as it normally sits (as I've already done a lot of the 3D models haha) but this can be changed if necessary.

Any input would be helpful or if anyone could point me in the direction of people who have used bike engines for their kitcars?

Thanks

Andy Bates uses this approach on his Sabre race car.

The trick seems to be to use quality components and get the alignment exactly right.

Quaife have a chain drive Torque biasing diff specifically for this purpose.

Hi, thanks for the replies, had a look at the sabre there, it uses the quaife diff as well, it looks like the best one, but I can't really afford it if I'm honest, have seen some on online from self builds and was just wondering if these were any good or if they're not reliable?

Lots of grass track racers use them.

IIRC the Sylva R1OT(J16) had a chain driven diff from a Fiesta, if you used the one from the RS Turbo it also came with a LSD. As previously said, this is pretty common, have a look at the ZCars minis, or if you are after FWD then the Pro-motive do a mini subframe for an R1 witch chain drive.

I've been researching the same sort of thing, came across this site - http://www.westgarage.co.uk/forsale/kits/kit2.html

Sylvia use a ford one in their R1ot kits

I'd been looking at those ones, they'd do the job! and I know a few people who have done formula student so I might try and get in contact to see if they used their products.
