996 Carrera 2S?!

[Mario149]

Yes, you read it correctly!

This is probably a daft question but I thought I'd ask it anyway:

Is it possible to physically disconnect the 4WD on a C4S such that it could be driven with only RWD?

Slight clarification to the above is that I'm sure you physically can disconnect the 4WD by removing (some) component(s), I guess what I'm asking is

a) is it an easy and reversible job? (e.g. your local indy sticks it up, gets under it and 1hr later hands you a few car parts to hold on to and an invoice)

b) if (a) is true, would it still be safe to drive electronics-wise or would the PSM get all confused that only the rear wheels were being driven?

In case no-one has worked it out, I'm trying to see if it's possible to experience a RWD 996 for say a few weeks without having to change my car or rent/borrow another!

Cheers,

Marco

That is a bloody good question!!! Any one know the answer??

I know that when they dyno 4WD cars on a 2WD rolling road they disconnect the front prop shaft. However, I don't know what the effect on the front differential and viscous coupling would be if you drove it like that - ie the output shafts driving the input shafts. I don't think the PSM would mind, as long as it can read the ABS sensors on each wheel it should work OK. Personally, I'd be a bit concerned about trying though - especially if you came unstuck and had to explain it away.

Of course, you wouldn't get the true effect, as you have all the extra weight of the front diff and drive shafts. The wider body and rear tyres would also make it difficult to compare with a narrow-body C2.

The car would still be road legal though wouldn't it? It's not like it would be any less safe than a C2

So that should be the best of both worlds then More traction and stability than a C2, with less bobbing and better looks

On a serious note though, who do people reckon I could contact for info on whether it would actually damage the car or not? I'd like to ring up an OPC but I suspect they'd probably laugh for a bit, then admit they didn't know what would happen

I have seen it done on a 996 Turbo - cost approx 120 quid to convert to rear wheel drive - not sure where I saw it now though - maybe on Renn website . I will look for it.

that would be great if you could, cheers! Presumably if you can do it on a Turbo, you can do it on a C4S, same running gear and all that

I have def seen this - maybe would be better if you put a post on pistonheads and renn as you will get a faster reply.

Hello from over seas. [8D]

A mate of mine has done this on his turbo so it is no problem, but a bit expensive. He had to do a remap as well, I guess it's the computer that controlles the drive between front and rear.

So by all means possible but not an easy job.

Cheers
