What is a dump valve for? Do I need one?
Discussion
I've heard Scoobies and the like making that hissing noise from the dump valve. Just been on Youtube and seen the procedure for fitting one to my car's Mazda 2.3 DISI engine. Apparenlty accorind got the vid my car has a plastic one - it doesn't make the hissing sound.
What are they for? Whats the advantage? Surely that hissing noise is escaping pressure which could be better used being converted into power.
Or is it just a chav thing that is of no use.
If anyone could explain, I'd be grateful.
Cheers
