Just showing the sounds made by a Bailey DV36 Twin Piston dump valve on a fiat coupe 20v turbo. Only gets up to around 0.7 bar, so not the loudest dump in the world.
i had that dump valve took it off gained 3 bhp it sounded just as good with the standard one when i changed airbox for k&n i got another 2 bhp from that also.
Tickover sounds poo.
Under throttle that sounds amazing!
What mods do you have apart from the dump v?

Engine wise I have a custom built stainless exhaust, a drilled airbox with uprated panel, an electronic boost controller and a new chip.
I also have adjustable coilovers and uprated brakes.

I tried doing that on my first vid, but the camera fell over and I had to fish it out of the engine bay. :p
