Default bogging down on pull off

Hi guys
If I pull off fast my scoob seems to go then it will bog down really bad before going again smoothly. Any ideas why this might be.
Cheers

The fact you're below the boost threshold of the turbo?

Try a bit more throttle and see what happens.

Sounds like you're experiencing turbo lag

7k rpm and slide your foot off the side of the clutch instead of lifting it off. Should sort your problem. lol

And introduce yourself to a load more problems when you say goodbye to your clutch and gearbox.

a 4.5-5k launch should be fine if you control the clutch properly.

Maybe a bit more of an explanation to how you mean it bogs down then goes again?

Goes again when you change gear? Are you launching of just flat flooring from stand?

Have you had a service lately? Maybe dirty air filter?

It takes some practice to launch properly, absolutely fantastic when you get it right, in the wet, with all four wheels spinning..

Get it wrong and that stinky burnt clutch smell puts you off doing it again for a while.

Agreed! minor bit of fish tailing as you launch it onto a 70mph road from standstill - nothing like nailing it from 0-70mph as quickly as you can.

It bogs down when you release the clutch too quickly with not enough gas, or you come off the gas too quickly. Done it a few times myself - you can save it though by partially re-engaging clutch, and rebalancing the throttle.

All about technique. Nothing wrong with the car. But unless you are trying to impress some 17 year spotty little chavs, what's the point?
You will just end up frying your clutch, snapping a drive shaft and destroying the gearbox.

Some people just dont get it! Launching is fun, and actually a very hard skill to master, I wouldnt say I have mastered it, but hell its fun trying

I launch on a almost daily basis....due to the busy junction I have to pull away from on the way to work. The whole reason for me having an AWD car....So I can launch away from a busy junction regardless of the weather with minimal drama.

Scoob just lapped it up. Get the turbo spinning with some full throttle blips, feed in the clutch and away I go "into" the gap in traffic.

Its new owner often did the same (after I taught him how to launch it without bogging down ).


If a driveshaft breaks IMO, it was on its way out anyway, usually rust pitting creating a fracture initiation point. If the prop mount starts thumping, the rubber is perished, so would have failed eventually. If the CVs fail, it usually becuase a boot has failed in the past and allowed water/dirt ingress.

If the clutch or gearbox fails, well ok, that's usually your're fault (or the previous owners). But on the grand scale of things, more people fry clutches sitting stationary in gear (wears the release bearing and weakens the springs) and holding it on hills without using the brakes...so as the driving instructor once taught you: "handbrake on, engage neutral, remove foot from clutch pedal". And more people fry gearboxes by forcing the syncros...too heavy handed engaging gears by eitehr forcing the lever too hard and/or too fast...the lever only needs the force of one finger to change gear...not a whole fist.

Anyhoo, point being mecghnical sympathy extends far beyond launching. Just general city driving could easily knacker a car's drivtrain if badly driven....My R32 was found to have a worn out clucth at only 28,000 miles just after I purchased it.....it was a East London car, say no more.
