what about this one My link

Cheers mate I'll have a butchers!

I'll order a new spring up ASAP if it's needed

Forge come standard with green spring.

If you are running that ammount of boost you defo need the yellow spring.

See forges website to check out the spring rates

When I fitted my Forge DV I cut the corner off the cover to allow the top pipe to fit better. See this pic(before I removed cover altogether)

eddie4x - I would not touch the DV in that Ebay link

The Forge blurb in the above link says for 26psi peak a green or yellow spring is recommended,Mine peaks at around 20psi and have no problems with a green spring fitted.

Thanks Mark!

I think you need to read the extra blurb as the green spring should only be good up to 15psi and the yellow spring from 15psi to 23psi.

This is the ratings:

Valve Spring color coding

Green - 5-15 PSI

Yellow - 15-23 PSI

Blue - 23-30 PSI

Red - 30 + PSI

The forge Site is a little confusing but the above is correct.

My car ran ok on the green but better on the yellow.

what about one of these

To quote from Forge website

Please Note:

The quoted spring pressure (Psi) relates to the un-assisted clamping force of the spring and should NOT be taken as an equivalent to boost pressure when determining suitability. Once a valve is fitted to a car it is subjected to various pressures that act upon the diaphragm or piston to aid its respective ability to seal or hold boost. An example of this, would be when using a FMCL007P valve on a 1.8T engine as found in the TT 225hp. The boost pressure on a "chipped" car can peak at 26psi. The recommended spring would be the Green or Yellow

what about one of these

Boy I want one of those......................
