Hi just wondering wot the pros/cons of havin a dump valve, I was told that fitting 1 can lower the turbo boost pressure not sure how true this is????

 

As long as you go for a good make of dv like HKS you will be ok. Recirc are the best type to go for but a lot of members also like the VTA type.

Cant we make a sticky thread about dump valves and be done with it for once and for all?

 

I'm pretty sure that a apexi is fitted on mine, just when I was told they can poss drop the turbo boost was thinking of takin it off. Is apexi any gd?

Ah il hav a look 2 c exactly wot apexi is on there 2moro. So do u gain or lose any power from a dump valve or is it purely just 4 the noise? Sorry if this sound silly this is my 1st scoob!!!

 

Some people say you do by using a vent to atmosphere some say you dont.
I run an HKS SSQV3 and havent lost any performance.

 

From what i have read and taught myself, stick with what you have, i.e the OEM part.

Take advice from the some of the great people on here. There are some really knowledgeable people on here and you will soon be able to tell the differences between opinion (Buy a Supersonic, twin horn off ebay), experience (Stick with OEM) and technical knowledge (The reason why you want an OEM is because......).

If you want that big whoosh sound, buy a Renault 5

I suppose it's the start of 2013 so we might as well start another dumpvalves thread

Or we could just paste and copy all the classic remarks and make it a hundred pager to make it one of scoobynets BIGGEST threads of all time


Wwwwhhhhoooossshhhhhh.

You're a fan of the VTA then.

 

I just don't understand what all the debate is all the time a dv is mentioned,some people use one others don't and keep the standard one in place,where's the topic in that.so I will end this how i started it .

 

Some of us believe that VTA DVs are not the best thing for the smooth running of an EJ20 if just bolted on in place of the standard recirc.

However it is clear the way the Subaru scene is going (i.e. advice newbies don't want to hear is not welcome) so I am changing my stance to if you want one get it bolted on and happy motoring

 

Whats a dump valve?
I

 

Its more so the fact that folk don't listen to the advice they're given regarding VTA dump valves

 

I Agree 100% with your stance rough running can come from the initial set up after fitting one and other supporting mods,my car was properly mapped after I fitted one in conjunction with a front mount intercooler i just found it brought the spool of my turbo back faster after a gear change that's my opinion anyway and I think that most people that buy a car should realise that they bought it for themselves and do not need other people's approval to modify it.safe modification and what's in or not in fashion in the Subaru community is another story.

 

Hav looked at the dv 2day at is a sytec r these any gd?

 

whats your stance on txt speak ?

 

???????

 

Is it a coincedence that everyone asking about dump valves uses text speak like a 12 year old??
