Hi all,
I'd thought about a similar setup for my autocross / autograss car. But this car will only be driven on loose tracks. In autocross / autograss
4x4 is a huge benefit. Do you guys think i can run a similar setup without a central diff? Our tracks are normaly very loose heavy sand. i'm
thinking about using two ford sierra diffs connected permanent to each other with a propshaft. The rear diff will be a locked (welded) one and the
fwd diff will be open. A bike engine is then placed in the mid, with drive sprocket slightlly fwd of the right hand output shaft where i want to put a
70t sprocket on. So actually the right hand rear output shaft is driven and rear diff will distribute it to the front end.
In our class bike engines (hayabusa / zx10r / blackbird etc ) are often used with a sprocket ratio of 70/14 and rear driven on locked diffs or 4x4
with chains going all the way from backside diff to fron chain diff.

My limited experience with chain driven cars put me off them for life, and that was track only use too lol.

The "why" campers surprise me. We should encourage differences, all our cars are different. Who cares if it is slower, his / her
competition won't!
The advice on chains is good to see, plenty of experienced folk here on that subject, I am not one.
I would add to look at other diffs though. MX5 may give you close enough ratios and are alot cheaper and plentiful.which is what you may need for this
development.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
Please read my ring story:

Did the OP ever get anywhere with his design?
I doubt he's following the thread 14 yes after the last posts.
