Hi all
is it possible to add an aftermarket dump-valve to a stock R56 Cooper S (for that swoosh sound...lol)?
Also its an Automatic, would that make a difference?
I have an intake on the car and the swoosh has increased immensely.
Car gained 3wkw with the cone filter and is way more responsive. Car is now sitting on 131wkw's @ KAR Performance Dyno.
