I am currently after 2x dump valves for my UK TT Z, however i would prefer a wastegate as i prefer the sound,

 

is this possible? what is the difference in installation? & where can i buy them from for a Z???

 

cheers guys, Dan

Wastegates and dumpvalves are completely different things! Your turbos already have wastegates built into them. Wastegates are on the exhaust side, dumpvalves are on the compressor side....

i know they are different, you mean i cant have loud ones on my car so i can hear the turbos chatter...?

What you want is the noise called "wastegate chatter", but is actually nothing to do with the wastegates, its an incorrect term. Turbocargers require wastegates to release the excess boost into the exhaust system. Wastegates dont make the noise.

 

You can get the noise by running without any recircs or dump valves. The noise is from the air being forced backwards through the compressor wheel on lift-off, and is very unhealthy for the turbo !

As above, all turbos have wastegates or the boost would not be regulated.

you mean like this...

There are many dump valves for sale on ebay which is probably your best bet!!

 

Waste-gate chatter may sound good but as mentioned it aint good, It is the sound of your turbo chargers in pain!!

Takes me back to the days when a lad came into the shop i worked in and asked to buy a dump valve, I asked what sort of car it was, he told me an escort, an rs turbo? i asked, no a zetec he told me.

 

I sold him some neons and a flashing gearknob instead!

LOL @ this thread. Dump valves suck anyway.
