Please help,

I have just recently fitted a Forge dump valve. But I have a problem there isn't a loud 'whooshing' noise just a very subtle one which I can barely hear. Does a dump valve need some time to run in or do they instantly run well. Would it be a good or bad idea to spray WD40 on the valve(maybe its stiff). Please help.

Thanks

forgot to put email notification...................

Respect!

 

dont put WD40 on it..! it has its own lubrication... have you got it all connected up right...???

Did you fit it on the right pipe.... i.e the one coming from the intercooler and not from the intake...???

Have you got a digital camera, if so take some pics and post them on here so we can see if its all connected up ok..

I'm assuming you've bought a vent-to-atmos one??? I have a Forge recirc DV - it makes a very (very very) subtle whoosh on dump, certainly nothing like the VTA ones!
Assuming you have bought a VTA one, check the piston is working properly (give it push from underneath). They can stick when new (I replaced my first recirc one as the piston was sticking/squeaking).

 

The forge comes with a pretty strong spring.
If you give them a call they will supply you with a replacement spring. From memory, they come with a red spring and you want the blue one.

I may have that the wrong way round, but I'm sure that's right

 

chockymonster - thats right Red gives chatter, blue give whoosh!!! Phone Forge and they'll send the spring FOC

 

Me was right

 

being lazy anyine got the phone number for forge????

Thanks Very much for that, I am going to give Forge a call. Fat Boy Slim the number is 01452 380999.

Thanks for all the help.

My Forge VTA came with the blue (weaker) spring. It wasn't very loud compared to my old Baileys Evo VTA and the release was very short and sharp, again compared to the Baileys.

Phoned Forge and they sent me the red spring, now at low boost I get the chatter and at high boost I get the Ptshht. The chatter by the way is actually caused because there isn't enough pressure to open the valve and it's the air stalling the turbo fins, not overly heathly for your turbo.

Thanks everyone for your help, Just phoned forge and they are sending me the Blue spring which is weaker free of charge. Hope they are easy to fit.

Thanks

Very easy.
Use a small allen key to undo the 6 black bolts.
The two halves seperate, take out the big spring and replace it with the new one.
Put it all back together.

 

Thanks Chockymonster.
