Dump valve
Turbo Mini Forums

Hi folks.

Am in the process of ordering the bits I need for my conversion. Can someone please tell me about the dump valves available?

I like a nice loud dumo (don't we all?) but have heard conflicting stories about what can and can't be fitted to the Metro Turbo lump.

So - what DV fits and is nice and loud?

Any normal dump valve will fit. The conflict is between the 2 different types:

One's a piston type dump valve. Sounds nice, seals well. I had a le-mans grp A version on mine and loved it. Only downside is that the fuel in the air tends to knacker the rubber o-rings apparently which means they have to be replaced. Not a big deal i dont think.

Other sort is a diapraghm type, these are supposed to be the best for mini's as there are no o-rings/piston to stick. thing is the diapraghm often split on them so its worth getting a kevlar one. My mate had both sorts on his fezzy turbo and the diapraghm one was louder so he said.

Personal preference in a way, diapraghm's are supposed to be ideal for mini's but piston ones work just aswell.

Not much help really was it

I've had a diaphram type fitted for about 6 years, the original rubber diaphram did'nt last a year but i replaced it with a Kevlar one and it has shown no signs of weekness and it does get some abuse.
