Douglas Anderson at westgarage engineering if it's mid engined although in a Haynes chassis I can't understand why you'd need a chain diff unless your going to chop the car to make room.
In which case a mid engined chassis like the riot on eBay would be better base to start

I run the quaife in the Jedi but it's a properly designed mid engines racing car. How are you squeezing one into the back of a kit car chassis and retaining wheelbase and bodywork? Have you got any pictures?

Normal bike engine in a Haynes is run from the front with a propshaft to get the power to the rear. That way you can use a normal diff (and keep the price down). The only thing you need is a propshaft adapter which can either be made from a front sprocket or can be bought as a bolt on piece.

This is the tried and tested route. No need to reinvent the wheel
You will need a prop adaptor and 2 piece prop, connected to a Sierra diff.

Have you considered a reverseing solution?

What part of the UK do you live in? There is bound to be someone close who has a BEC for you to look at.

Explain exactly what you are wanting to do and in what chassis!
You've posted in the mid engine section but said you're using a haynes roadster chassis and a chain diff?
Surely you weren't intending to run the engine in the front but chain driven to the rear? Where we're you planning on running the chain? As the front sprocket would be way off the centre line of the car?
Or were you planning to butcher the chassis and run it mid engined?

I have a very successful front engine chain drive MNR race car so don't let the none believers put you off. I run 2 chains with an idler in the middle. I used a rs turbo viscous LSD unit mounted in custom alloy blocks and bearings. You could do the same with a Mazda mx5 LSD or Sierra, pretty cheap option and easy to do.
