Bailey DV30 dump valve

[AndyP]

Since removing the airbox and using a K & N filter I've noticed there is much more noise from the dump valve. I'm currently using a Milltek hyperboost, but Bailey claim their DV30 is much quieter than other piston type valves.

Can anybody using one of these confirm this?

It is however the Baileys dump valve are a pain in the ****, the piston in them sticks alot and you have to lubricate it at regular intervals

I've heard they are good, but are they quiet?

The loudness isn't going to be greatly reduced IMO, the noise is coming from more air being recirced and the free flowing filter, you want to here it on my cone!

not on mine, but i have 2 and both release on atmosphere!! When plugged, they should be very quiet!

on mine they sound more like the S1 though

That's my fear, even running low boost I think it's too loud so I dread to think what it's like at higher boost levels.

Put a standard airbox and paper filter on it then, nice and quiet.

I've got a spare dv if I can locate it, next time your around you can test to see if your theory is right

I wanted to keep my RS2 airbox but it will not fit with the Wagner manifold and 3071 turbo

Try wrapping the DV with exhaust rap to reduce the noise.

[driftin jo]

If that doesn't work you could just set fire to it .

After all the other problems it's had recently, it has come close to being BBQ'd, trust me

[Jamo]

lol well it will but you need to cut it

Andy, I'm still running the RS2 Airbox, you just have to cut the foot off and make a little bracket.
