Hey fellas,

In my never ending quest for silent gear changes (i.e no dump valve noise)
I'm turning to you guys for help.
Basically I hate chatter and dump valve noise between gears. I'm more the silent/ not into drawing any attention to myself and my car whilst driving.
Does anyone have any ideas on how I can go about this?.
The original airbox and bosch dump valve was pretty good, but when I installed my RS500 spec intercooler I had to lose the ducting to my airbox so I felt a Group A cone filter was a better choice.
With my current setup of a Bailey DV 30 dump valve and the pipe running back into the turbo feed hose (see picture attached) it's alot better than say a Bailey DV 24 dump valve.
But what I get with the current setup is the air blowing from the dump valve, travelling along the hose and making its way out through the pod filter.
It's not super noisy but it still pisses me off.
Any suggestions, new type of dump valve perhaps, maybe I build a box around my cone filter to silence it a bit?.

Cheers guys,

Ollie.

 

Stick the airbox back on!!! Good enough for the RS500 touring cars. Fit a K&N panel filter, job done!!

 

Take the turbo off LOL

 

The only touble is kjc300, that with Pace RS500 spec intercooler fitted mate is that the square ducting that feeds the air box from the front grille had to be removed in order to fit the intercooler.
So all I used to have was the air box with out it's ducting sucking hot air from the engine.

 

I know yours is a saff, but maybe you could knock something up like mine??

4" ducting down to the bumper grill.

airboxes are cheap as chips off ebay, bit of ducting was £25 for 1m of 4", and a tube of fibreglass!! Job done!!









Dump valve piped back to airbox lid.
