...without stalling: is it just my car, or am I doing something wrong?

I bought the car in July, and have always found it a tricky little bu**er to balance the throttle and clutch when pulling away, particularly uphill; the difference between stalling and 4k rpm a mere brush of the throttle apart.

A recent revelation, read on here a few weeks ago, was the technique of not touching the throttle at all and letting the ECU deal with matters throttle. This works very well, except when on or about full lock, when I find it almost impossible to reverse the car up hill without stalling it - and any attempt to keep it running by brushing the throttle results in instant revving accompanied by a nasty smell of clutch and a wince from the wallet area thinking about that 2.5k clutch replacement....

I've never had this problem with any other car I've driven, so don't think it's a lack of skill on my part - does the tricky throttle ring a bell with anyone else? Does anyone else notice the same full-lock problem?

Thanks in advance,
Phil.

well not with the full lock on but the rest of what you have experienced I can empathise with! When I first got the V8V I stalled it a lot until I learned the idiosyncracies of the throttle. Reversing was and remains challenging. I have to reverse up a lengthy drive with a turn at the end and if I don't slip the clutch the car tends to shoot off and I risk hitting one of the other cars there. So I've took to dipping the clutch right down but I too think of the costs! For me it was a question of getting used to it - you are certainly not alone, unless we are both crap drivers of course!

I'm reading that and thinking that you are not touching the clutch while brushing the throttle? Is that correct?
That being the case then you should not get a nasty clutch smell as the clutch should stay fully engaged, no slip = no smell.
Are you 100% sure you're not riding the clutch unintentionally. I know that reversing these things can be kind of nasty. Only time we get a nasty smell is when I intervene with the left foot.
If it does, I'd get that looked at as it shouldn't do that,
Gotta agree, reverse gear is truly bonkers. How that got signed off remains a mystery to me. I've not tried but I reckon 50 in reverse should be entirely do-able.

On the PDC I am actually going to ask if I can stick a V12 in reverse and red line it. Just for giggles...

IMHO the gearing on reverse is way too tall. best bet is to reverse into your drive ( freewheel) and then drive out.

I am happy to add myself to the list (either as a crap driver or one who thinks it's very hard to control a reversing manoeuvre without revving madly or slipping the clutch, and nigh on impossible on full lock).

Peterr96 - are you suggesting that you are able to reverse with the clutch fully out? It feels to me like the minimum speed doing this would be 10 or 20mph and have never dared to do it!

Perhaps a list of minimum speeds various vehicles will do in reverse on tick over would be a usful illustration of how bad a v8v is.

edit - dose speedo work in reverse confused

I have nothing empirical, but I suspect reversing uphill will be one of the biggest causes of premature clutch failure.

Balancing the car on the clutch when going up hill is tricky, but can be done. However, I'd avoid having to as often as possible.

Why are you having to reverse on full lock? I would have thought that to be a nightmare in many cars.

V8V can do 63 mph in reverse. It would idle (assume 1000 rpm) at 8 mph in reverse.

Yes do it! I wonder what the record is reversing down the mile straight!

Exactly so. It goes way quicker than you'd ideally like though so better take some spare undercrackers with you.
I recall quite vividly the first time I had to reverse it up a hill. The stink! (of clutch!)

63 mph! That is even madder than I thought!
With reversing gearing like that it could only be an Italian gearbox!

No, I am holding the clutch a biting point to go from stationary to moving backwards slowly, for example when parking, when you can't fully engage the clutch. The clutch doesn't slip when fully engaged.

Yes, the ratio is closer to that of 2nd that it to 1st.

The quick answer is "only when unavoidable"! - last night's example that prompted the question was the need to do a a three-point turn in a cul-de-sac (after visiting a friend), that necessitated reversing into someone's driveway, which was up a slight incline. It was dark and unlit, so a clutch out 8 mph wasn't an option!

As I said, I've never had a problem in any other car I've driven, so thanks to everyone else who's confirmed it doesn't appear to be just me.

The real question is why did AM choose such a high ratio in the first place?

Ah well yer screwed in those situations! I think we've all been there. We're 35,000 up on the original clutch.
I believe others have even higher milages.
If you do this on the odd occasion I wouldn't worry too much.

It would appear so!

Whilst eye-wateringly expensive, I think I'm less worried about the clutch wear than I am about looking like a completely useless ar$e who can't drive his expensive car for toffee...

Oh well frown
