Read again what I wrote above. All drive wheels push the same as the wheel with the least traction.
1 wheel on grass and 4wd means all four wheels pushing the same as the grassy wheel.
1 wheel on grass and 2wd means two wheels are pushign the same as the grassy wheel.

End result. 2wd vehicle has half the drive force and is possibly stuck. 4wd vehicle drives off no problem with twice as much traction.

Roundabout is exactly the same. Vehicle is still driving with 4x the grip of the spinning wheel.

Dougal, I'm really confused now! What your saying is 4wd vehicles have more opportunity to gain traction with 4 wheels instead of a 2wd vehicle because of 2 wheels. I agree with this.

If you are in a extreme condition like jacking one wheel of the ground in a 4wd (AWD) and 2wd which one could drive away without centre diff locked or diff lockers?

Excellent, progress.

If you are jacking wheels off the ground, why would you be in 2wd or 4wd unlocked?
It seems a completely artificial situation.

Dont worry tebone, I'm sure you might have a handle on the effects of HP, Dougal may not realise you are applying 383ci Supercharged chevy ponies to the ground;), Dougal seems to think he can spin all 4 wheels with his Isuzu with ease, I've had shots at him over many years, for being incorrect, but he never backs it up with proof..

He just argues theory, but unfortunately, those that actually work in the realms of reality, know that on almost all occasions a classic RR will loose traction with a front wheel, the left if in a straight line or whichever is the lightest whilst cornering, just as an open rear diff under equal traction will always loose traction on the drivers side

You may continue to argue if you wish, but I think you may find more pleasure in poking your finger in your eye, argueing with an engineer using reality over theory just never seems to cut it:)

Thanks Matt. Are you working or at home? Matt I'm not as smart as these other guys but as you know we tried a lot of things with our Rangies especially trial and error.

Thats what I was trying to explain. With a lot of hp or torque the front end becomes very light (wheel of the ground) and thats why I was getting more traction from the rear end with the rear wheel drive set up instead of constant all wheel drive!

That's because you've lifted it and screwed up the suspension geometry. Get a torsen centre diff and you'll be sorted with much more traction than rwd.

Got photos of your rangie doing a wheelie or should I put you on the same ignore list as your mate?

Haven't got photos but turning left in 1st it will pick the left front wheel up in the air and thats the problem with my wheel spin but under normal driving its fine. Can your diesel rangie do this? Probably not. I'm just commenting on my old girl how it behaves and trying to give some advice to the guys who are starting new projects. The biggest driving factor for me to convert to rear wheel drive is to make it more reliable. Could you imagine all that torque through the centre diff spider gears and axles, cv joints in the front end. You might thing I'm full of it I don't really care.
Yes I have a 2 inch lift but hasn't most rangie owners. Just because someone doesn't agree with you don't have to get nasty.

why would u question if his rangy can do a burnout, i run a mild 9.7 to 1 357 n/a chev and i can spin the wheels without even trying, so i can imagine what his sc 383 can do, ps is that the rangy that was at rovercentre in balato rd skye a while back, ?

No, mines a Green 86 model.

Yes it can and does. It depends on the corner geometry and speed as to whether it spins up the front inside or rear inside.
Given that it switches between front inside and rear inside, it's kind of obvious that trying to put all the drive (2x as much as 4wd) through the back wheels in those situations ain't going to help.

You're not going to make it more reliable by sending 2x as much drive through a standard rear axle with oversize tyres.
If you've spent some big $$ upgrading that 110 rear axle you might.
Fulltime 4wd puts half as much torque through each axle compared to 2wd.

I don't have a 2" lift in my 3. I'm special apparently. But since emergency maneuvres have saved my bacon at least twice on road I'm happy with that.
A lift steepens the angles of your suspension links, making for more antisquat in the rear and more antilift in the front. This reduces traction on the front wheels under power.
It also raises your COG and causes more weight transfer under acceleration, braking and cornering. Which makes your problem of picking up tyres much more frequent.

Sorry this must be a difference in lingo between AU and NZ. Here a "wheelie" isn't a burnout. It's picking up the front wheels under power. I'm not sure what Aussies call it.
