Forge Alloy Dump Valve
Recirculating version for 1.8 20VT, both Leon and Ibiza.
If there is one mod you should get it's this one.
Fitted for less than £90 at RSD though other suppliers should be able to source these without much trouble.
The throttle response is much better, the boost stays up thru the rev band much longer, dont get it wrong you wont get more power with this, but it makes the power these cars do have much more usable.
It keeps the turbo spinning thru gear changes so making the uptake in the next gear much more fluid.
Most of all they look great and gives you something to point at under the bonnet.
Take a look http://www.forgemotorsport.co.uk/vehicles/audi.html
I can not recommend this little mod enough, i was well pleased with the result.
The Bosch standard ones, are basicly very cheap small plasticy things that are prone to failing, these have already been warranty return problems for some VW/AUDI and Now SEAT owners.
The only thing a dealer will do is replace it with another badly made replacement.
Do yourself a favour get one of these
They are fully servicable so if it ever needs something replaceing its a simple job, not a complete replacement.
This is a recirculating dump valve or its proper term Diverter Valve, this means its quiet, it doesn't whoooosh or anything so you don't look like an RS Turbo nonce
And for those that do want a whoooosh there are those types available, but be WARNED, you will lose power possibly several BHP and your Turbo will underperform.
The reason is that VW Turbos are quite small, and rely on every bit of compressed gas they can get to do their job, by replacing the diverter valve with a release type you lose a lot of boost pressure.
In cars with larger Turbos' for instance an Escort Cosworth, they benfit form release valves as the higher gas pressures can cause the fan blades to stall between gear changes, these can result in a worst cars of the blades shattering under the stress.
But this is not an issue with these smaller turbo's
SO WHAT YOU WAITING FOR GO BUY ONE NOW
