hello everyone,
i'm looking for a dump valve for my 2000 gti turbo 150bhp. currently i have a pipercroos viper induction kit fitted.
i want a dump valve thats going to sound really loud, but also is of good quality and that won't give my car ideling trouble.
can anyone help??????????????????
???

Give Forge Motorsport a call, they were really helpful when I needed one for my GT4 and ended up designing a new one to fit my car! They worked on it till it was just right.

Just recently had the same discussion with myself, forge, hyperboost etc ???
Anyway, decided on the Forge DV 007 and just received and fitted it today. Results are yet to be confirmed but have just been out for a quick spin and it has made the car a lot more smoother and responsive, and I think (maybe it was just me like) but the turbo whistle was a lot more noticable as well.

::)any chance of a quick update as to how your dump valve has been performing? Looking at buying one myself but am in two minds like yourself. Any regrets?

Just bare in mind that I know nowt about cars apart from what I've picked up on various forums.
Before fitting the DV, my car was really starting to surge and jump about, not holding the boost when going through the gears etc, and generally wasn't a very nice driving experience. Anyway, the original Bosch DV was making a horrible noise when lifting off the gas, as though it was catching on something, not the normal phssst (??) sound. I know it's hard to explain a sound but anyway !!!!
I could have went to the local stealer and replaced it with another bosch unit, but read elsewhere that these could also fail at any time. I don't know if that it is true, but have read that on more than one occasion.
So I decided to splash out once and for all and go with the Forge 007 (as opposed to the 006 which apparantly can have difficulty in fitting under the enginer cover) due to other peoples experience with the unit and also the fact that it doesnt need any maintenance.
Fitting it was a piece of P, even for me - 10 - 15 mins and it's on. Since installing it around 1500 miles ago, the car has been completely different to drive. It is now a lot smoother through the gears, pick up on changing gears is instant and turbo lag has dropped considerably.
The weekend I changed it , I had to go to Barnsley with work and took me own motor and can honestly say that driving down there was absolutley brilliant. Although I'm sure I might have been done for speeding on the M1/ A1 (paranoia maybe??) and I'm just waiting for the speeding ticket :'(

I can also confirm that the Forge DV007P is a great upgrade.
-
What sort of money are we looking at for a forge dv007 then, this is my first turbo car so bit new to it, any other good upgrades??

Does the forge 007p make a dump valve noise when lifting off the throttle???

not sure about now as things have moved on and i havent got a turbo golf, but when iwas into my rs turbs and other blown cars i always had bailey dump valves, good quality, they had a nice sound but i wouldnt say there were cheesy noise!!!!

Knowledge gathered from my Fiat Coupe days (happy days, performance missed :() ....
If you want the ppppsssshh-scare-old-grannies-on-the-pavement-noise go for a 'dump to atmosphere', but if you are just after a decent 'recirculating (to the air box) valve' (as is the standard VW bosch one) go for the Forge Dv007 or 6 (think they are about ?70-80 - these were very popular on the Coupes - never got round to it myself though) Go here: http://www.forgemotorsport.co.uk/products.asp?cat=TUNDV&product=FMDV006
They are a piston type that are supposed to be more accurate/consistant than the plastic diaphram Bosch one that'll be on. The Bailey valve was also popular (DV30).
Also, drilling (several 32mm holes) the airbox was quite popular, if you are after a bit of noise this might do it, but not sure if this would much up your airflow readings ???.
Cheers
