thewelsho Posted May 12, 2006 Posted May 12, 2006 Hi All Does a dump valve affect engine power, consumption etc. or are they installed mostly for the sound effect? Much does it cost including fitting? Cheers J
ANDYJDMSTI Posted May 12, 2006 Posted May 12, 2006 prices vary from about £70 - over £200 depending on what you go for. does nothing for power, just a noise.
david_taylor Posted May 12, 2006 Posted May 12, 2006 The purpose of a dump valve is to keep the turbine in the turbo spinning between gear changes, hence no turbo lag. So thats the only real benefit, no power. I was also advised they really are just cosmetic, unless you are running a really high boost. I had one on my old RS turbo, after 6 months it was doing my nut in so I cut the top of my mums broom handle off and removed the valve and jammed the wood in to get peace! Best just gettin a filter if you have not already got one.
