Noble dump valve type?

[LaurenceFrost]

Hi guys,

Just something I was wondering:
Which type of dump valve does the Noble have fitted - atmospheric or recirculating?

The noise is LOUD, but doesn't quite hiss like the typical atmospheric valve.

My guess is that the valve is a recirculating type, but because of the sheer volume of compressed air, some of the recirculated boost escapes back through the cone filters the wrong way?

Anyone know differently?

Not a clue Laurence, but John Noble motorsport build the engines and their website is at www.johnnoblemotorsport.co.uk/

I found them very friendly and really happy to chat when I've rung them up.
