Ok at the risk of starting a i love them or i hate them thread, i was wanting to know what price and which make of dump vavle to buy as im getting my first wrx 2.5 in a couple of weeks. Its a brand new 2007 wrx in wr blue. I have read a few posts of people who either love or hate them here and as im new was wondering if they can have any adverse affects on the cars performance.

This has probably been done to death but any help would be good thanks in advance

 

Just put a GFB Stealth FX on MY06 2.5 WRX. 17 adjustable noise positions and adjustable spring tension for fine tuning. Got mine from subaruwrxparts.com, cos of exchange rate ($295). Great installation video no GFB australia website. You don't need the BOV gasket. The old one is removed as the BOV seals on the supplied o-ring.

£25 customs charge though !!

 

hi there , Welcome to the forum
If you use the search button at the top of the page you will find a lot of info on dump valves from previous posts

 

Turbo Smart seem to be popular as far as DV's go.

However...many people that have put them on (not strictly the Turbo Smart ones but any retro-fit DV) have reverted back to the stock item because they found the car to be more jerky with the aftermarket item.

(Many) others just frown on them full stop and don't bother in the 1st place.

 

Why fit a VTA air-bypass valve?

Good advice: dont mess with what you dont understand.

2007 what about warranty

 

I unlike some others do like the dump valve sound but as far as your statement goes i sucessfully managed to mod my honda ctr with a spoon cat-back,hondata ecu,aem cai and more buy simply asking questions on the civictype-r.co.uk forums who by all accounts are really helpfull, this was to educate myself on motoring which to my knowledge is why we share this info with each other.
Thanks for all the sensilbe anwers guys

 

Are you related to Eric Blair? On topic a VTA dump valve will have an adverse effect on your car which is designed to run with a recirculating one.

 

3 year Warranty down the pan

 

my scooby dealer is happy enough about the fitting of one and the laws surrounding the warranty say that the part fitted must directly affect the failure .example fitting an aftermarket zorst is not going to effect the starter motor if it fails.

 

Eric Blair was a prophet...

Power lies in the proles, always has.

 

Dumpvalve Don`t bother!

 

both my scoobs are still in warranty and have been back for repairs dealer hasnt said a thing and is not even bothered, one has a bailey which is quite nice and the other has GReddy BOV (stutters a lot)

 

There is nothing wrong with the standard re-circ valve.

If you fit a VTA DV then you will encounter problems.

Any air entering the engine will have metered first by your MAF (Mass Air Flow) sensor in order for the ECU to determine how fuel to provide in order to achieve an optimum A/F ratio. By using a VTA DV you will be releasing the air. As such the ECU will be unaware of this but still provide the fuel into the cylinder. This will end up being unburnt and run down into your sump. It's something known as 'bore wash'.

As has been said by the other members who have posted in this thread, do a search and you will no doubt find countless threads on the subject of VTA DV's.

In my personal opinion they are chavvy and only serve to impress schoolboys with that gay noise.
