I'm thinking about putting a dump valve on my 2009 TTS

1.because of the added efficiency to the turbo
2.the lifespan of my turbo as i drive it on track every few months
3. cause i like the noise :oops:

Is this chavvy or will i be called a chav in your opinion?

I think it's more down to the way you use it. If you are in Mcdonalds acting like a tit then yes it will be chavvy.I had a forge spacer on my tfsi Leon and I liked the sound when I had my foot down in country lanes.

If you want one then get one.

I don''t care if people think they are chavvy i like the sound and therefore bought one.

IF you like the sound and want one then get one. :p

I think what are chavvy is them fake dump valves the electronic sort. I saw an Escort mk6 with blue chrome wheels and a blatantly fake electronic dump valve sounded like something out of star wars :eek:

Yes

PS - how exactly does it increase turbo efficiency??
The general idea is that the dump valve reduces compression within the turbo by releasing compressed gases into the atmosphere with that typical hissing sound, and reducing the likelihood of compression damage to the turbo.

I'm not keen on the sound personally, but if you want one, why worry what anyone else thinks?

That's right, what you hear is the compressed air being released when the throttle is closed, but I was under the impression that VAG turbo engines recirculate that air into the system, rather than dumping it, thus making the engine more efficient.

Anybody care to elaborate on the way it actually works, as standard, or the alternatives?

I think the noise has been discreditted by the number of Scoobies running around, forcing a dump at every opportunity. That deffo is chavvy. :wink:

+1. Dump valves are certainly not a great idea on the 1.8T.

I had one for my Mark1 225. With a K&N filter fitted, it does give a nice sound off. I never noticed an improvement in performance. Its only chavvy if you have the rest of the car decked out with Ironing board spoilers and stupid wheels etc.

Each to their own!

Thats why most people fit the Forge 007 Re-circulation valve :D

If you want one, like them, and want to put one on your car then do it. No need for approval from anyone.

I personally don't like them due to the number of corsas going around with them on.
