Can someone explain me why is it bad to floor your tdi at 1000 rpm for clutch? I know it can also cause turbo surge when flooring below 1900 rpm but now im only interested why is it not good for clutch?

i would think that the judder that it produces would make the cluch bite harder if you are still puling away, but if you floor it with no cluch it wont do it any harm id imagin.

The clutch is essentially two high friction surfaces that mate when you release the pedal - put too much torque through this coupling and the friction will be overcome and there will be clutch slip.

Short and to the point!

If you're talking about traffic light grand prix starts, it's because the clutch has to "bite" for the engine to transfer drive to the wheels and you're making it harder to "bite" if the engine is spinning faster.

Same may be true if the clutch is already engaged, but I don't think the Fabia will pull that strongly from 1k rpm if you floor it so it shouldn't do anything to the clutch :confused:

yeh what he said lol some people have a way with words lol

though shoud you really "floor it" from 1000 rpm? Does it not upset the flywheel aswell?

That's what SWMBO said too :(

to shorten this story is it bad to for clutch to floor it below 1900 rpm? I heard many times that you should always floor it when its above that rpm...

Because the engine is generating a lot of torque and the clutch will slip?

In all honesty, i think Skoda have thought of this and put a clutch in your car that meet the demands. Remapped cars can suffer quite badly from clutch wear.

As has been said, if the clutch is fully engaged, ie not setting off from a standstill, you should see no problems flooring it at 1000rpm, as your turbo wont be spun up by then anyway.

.....new poll idea -"who is not a mechanic?"

Keep flooring it from low speed in high gear etc and your dual mass flywheel wont last long.

You ARE actually a mechanic....

Just on that subject, if I forget myself and hoof it under the 2k region, my 'box shakes. Flywheel? And what exactly is a dual mass flywheel, and can it be replaced with something lighter/stronger?

The dual mass flywheel is a two piece item with a shock absorbing silicone fluid between the two plates This absorbs vibtrations from the diesel engine and gives a smoother take up of drive and gear changes.

You can replace the flywheel with a single piece item. One of our SCN members who has a 230bhp Ibiza Cupra TDi has the full set (about

The load on the clutch is far greater at lower revs and road speed in the higher gears. The torque needed to accelerate the car is much greater in higher gears and puts far more strain on the clutch if the engine has to accelerate the car from low speeds in the higher gears. Think of pedalling a bicycle and trying to pull away or accelerate in a high gear, the engine, (you), has to put far more force onto the pedals and crank than is neccesary than if you'd accelerated up the gears.

In terms of mechanics, I'm assuming that having an uprated clutch doesn't mean the flywheel is any different. Its just I've noticed this "juddering" when at low revs (not booting it, but making progress) I think it last happened when I attempted to accelerate briskly in 6th gear from about 1500rpm. - Its really got me thinking that ideally you don't want to be booting the car on WOT until around 1750rpm when boost is kicking in and the flywheel isn't having to cope with mega torque? (i.e shift down for bhp, not torque I guess?)

Anyone else have some good anti-judder advice except laying off the throttle at tickover?
