Standing Start??

[robh964]

Hi all

Can someone give me some advice about 'doing' a perfect dry standing start in a '90 C4 please.

Tried various ways and always end up with a cabin full of clutch stench and banging rev limiter.

Thanks

how long do you want your gearbox and clutch to last?

if it's not your car, give it about 5k rpm and then side step the clutch (and hope it doesn't break anything)

if it IS your car, get it rolling and get off the clutch as quick as poss, i guess let the clutch out pretty sharpish at about 3k rpm - once you are sure the clutch has bitten then floor it. if you floor it too early you'll smell that clutch again...

Thanks for that, it is my car and when I tried the first option (5k and let go) that's when the smell occured, nothing broke apart from my eardrums due to the wives nagging about the smell!!!

Like this:-

revs about 3k, gradually let clutch out until you can just about feel it bite, launch the clutch and pile on the revs....
If you just boot it off the line, you'll smell clutch forever, and boy dose it stink, ask me how I found out.....

It's best not to do them unless you are racing. Hard standing starts put more strain on the running gear of a car than a track day would.

I did a few standing starts in my old tt. psm off, 4-5k then drop the cluth and hit the gas. The first couple of times i lit up all four tyres with no smell of clutch but the third time the clutch slipped and i reckon i reduced its life by about 20k in one sitting.
Since i got the X50 i havent done them because you risk breaking a drive shaft because the tyres are so grippy,and i want the clutch to last!

Thanks for the advise

I'm not planning on making a habit of this but sometimes the red rage gets the better of me with the ball bags that drive Maxy P Saxo's.

How did you find out???

1. Bolt on supercharger.
2. Engage clutch at 1500rpm
3. On take up of drive, lunch throttle to floor.
4. Change gear as quickly as you can.
5. Look in mirror for ex-surrounding traffic.

IME the supercharger makes it *harder* to do a clean standing start - like the extra torque isn't matched to the characteristics of the clutch / dual-mass flywheel, or something. Perhaps I'm just doing it wrong.

I don't like trying fast standing starts in 911s - the rear-engine traction and fat tyres make it hard just to light 'em up and smoke down the road. Using a load of clutch slip feels like I'm knackering the car. No doubt a 4wd one would be even worse!

I have accidentally done a quick start; you know the scenario; pull up at the lights in the wrong lane expecting a marina in the other but there's another porker.
Just gave it a little too much as I didn't want to bog it down and BANG the car exploded off the line - sounded like a shotgun going off and the ferocious acceleration really took me by surprise.:cloud9
Never again.

That's near enough what happened to me. Pulling out of a junction on to a dual carr.and thought I'd just 'risk' pulling out when a little gap arose. F**k me, the car shot forward with no spin, no tail wagging and dug into the black stuff nearly t**ting the bloke infront up the arse. Missus still says today that I knackered her neck doing that Like you said really surprised me (ie sh#t meself!!)
