Is there any performance reason for fitting DV's?

Mrs Mopp this is an easy one, I got a dump valve on my car for performance hence the 13.6 1/4 mile, it is all cause of my super dump vlave thing.lol

Why does the thread suck????? I am genuinely interested as to why some people fit a DV and if they do it for anything other than the noise - also what is it about the noise that makes you want to spent money for it???

if your driving your t5 as it should be no ones gonna hear a dum valve co all theyl hear is a whistling turbo ,screaching tyres, growling exhaust and a nutter behind the wheel laughing his tits off.......

Dump Valves do have a performance advantage but not at the pressures/use a Volvo T5 will see.

When a turbo is compressing air it heats up drastically - with a recirc valve yo are recirculating heated air whereas with a dump it is always 'new' air.

You would only notice a performance gain (very slight) in race use with full throtle gear changes / high pressures.

Recirc is better for normal use due to the metered air staying in the intake.
