Lightweight 4x4 system
Badger_McLetcher - 12/2/11 at 09:54 PM

Hey guys, recently I've been thinking about another possible project to do alongside my corvette thing. As part of this I'd need a compact, ideally lightweight four wheel drive system- again ideally with a transversely mounted engine. I'm considering the Nissan Pulsar GTIR system, which is about right but quite expensive- anyone know of any others?
Cheers!

VW Golf Synchro (Syncro?) from the older mk2 golfs?

The 4Motion is a non-permanent systen using a Helix Diff mounted clutch, but it's meant to be pretty light...

Fiat Panda?

Suzuki Swift 4x4

Very soon, there will be a mini doing the hills and sprints up here which uses a turbocharged G13B suzuki engine through this 4WD system.
I look forward to seeing it.

How much power are you thinking of?

If you do go GTiR, then it might be worth talking to Bob at http://gti-r-us.co.uk

I remember (from GT4) that Subaru do a small 4x4, it appeared to be about the same size as an early model Fiesta. The Justy iirc...

Locost alternative...Mazda 323 Turbo f

not sure if the early Justy used the suzuki 4WD system

most of the cheaper ones are part time 4x4s which is no use for a road car. What sort of vehicle are you making?


Badger_McLetcher - 13/2/11 at 09:34 PM

Cheers for the advice guys, I'd never even heard of a Mazda 323 turbo f like that!
JoelP: The idea is for a stripped out, lightweight 4x4 classic mini, road legal but can be used for hill climbs and maybe some kind of rallying if possible. As I said, still in the imagining phase atm!


JoelP - 13/2/11 at 09:47 PM

well, to open a can of worms, id just put a pair of bike engines in the back, and drive one axle each. Let the road link them together That would be light with serious power, and the 4wd would work fine. Use any diff capable of taking the power, and just flip the one in the front. Both would still be turning in the correct direction.

Hmm, twin 600's would be pretty damn powerful in that method, and if it was one in the front and one in the back there'd be a nice weight distribution

Funnily enough I was considering that myself, but I don't like something about having two unlinked engines... just seems wrong to me! :S Also twice as much to go wrong on that front!

True, but at least you can still drive home if one does go wrong!


Badger_McLetcher - 14/2/11 at 04:31 PM

Haha hadn't thought of it like that
The other prob of course is trying to keep it relatively standard looking! Would ideally like a street sleeper-esque kind of look
