just my worthless 0.000001p's worth

Of course there’s a middy discussion going on just now. But I thought you could do this – fit a standard fwd engine and gearbox fitted 90 degs from norm, one drive output locked on the gearbox. The other going via an angled propshaft to a diff (say a sierra item). His this been done before?

And yes I’m waiting on the computer again, can you tell?

Yes the sporting trials guys do this all the time.
It gives you a super low ratio for climbing 45 degree muddy banks...

Probably not what you are looking for unfortunately.

Edit: bugger came second again (must tell the missus )

I think one problem will be having two lots of final reduction, 1 in the front wheel drive box and 1 in the rear diff,

hmm I was not sure of the ratio at the wheels. Pity

though I thought the output shaft from the diff would double it's rpm when the other is locked...

Going back to lego car days there!

also since the diff planet-gears arnt designed to constantly turn at high rpm they would were out eventually

That’s a good point since the planetary gears are meant to only turn a small amount when going round corners and certainly not at double the rpm that the diff was suppose to run. So really this is a rubbish idea, oh no not another...sigh

why not just just use a vw passet engine which is inline and is front wheel drive?

Is it?!

didn't know that. I was pondering about the new mk single seater. Don't really fancy a bike engine, as the traffic in Aberdeen is awful

you could weld the diff solid and remove the other driveshaft stub and plug the hole into the diff housing that means that u dont have to bolt one side solid to the gearbox and you dont have the problem of the planet gears turning since theyd be welded and then theres the problem of ratio, that could be over come by flipping the diff welding a sprocket of the smallest diameter to the smaller side and replacing the pinion gear with a sprocket of the largest diameter that will fit and then driving it by a chain

personally i might do this myself but wont weld the diff i will instead go for awd for better handling on poor surfaces like the local roads

Seen a few 4x4 racers with this, drive shafts to each axle, only problem is max speed around 75 which is just not enough !

new it was a great idea!! he he

only major set back of this idea to get around finding a rwd gearbox is you still have to find a diff, that said you can buy freelander diffs new so maybe it is a way forward
