I have a forge VTA that I paid £150 for. I don't want to burn more money on a more expensive one, so was wondering whether I could modify the existing one to make it louder - any ideas/experiences??

 

What about running more boost ??

If you increase the boost or change the air filter to a metal mesh type one (Blitz or the new HKS), the BOV sound will get louder.

 

The best way to increase the noise level on a dump valve is to enlarge the holes from where the air is released from. It is not guaranteed to increase noise, but works most time.

I beleive on the Forge Dump Valves, the holes are circular, so all you have to do is to put the dump valve in a vice, and drill out the holes.

 

I found changing the spring made it louder also replacing the standard filter.

Open the under bonnet vents

 

If you have got a Forge Atmo type dump valve, the chances are you have got the standard "red" spring = No / very little noise....I had same, rang Forge and they sent me FOC a "blue" spring....takes two mins to change. Sounds very very nice now.

Ps watch if you swap the spring with the dump valve fitted to the intercooler that you dont drop any of the small bolts, they are a B******d to retrieve!!!!

Sure some one out there will have forges E-mail address.

 

Give forge a ring on 01452 380999 or 520358
or if you are lucky like me you drive 5 mins down the road to the factory
