Thinking about a dump valve jus have one or 2 questions.

1.Will there be more HKS ones availible?
2.Will it affect my warranty?
3.Could someone with no real clue fit this easy enough?
4.Will it affect performance or damage engine in anyway?
5.Is it easy to remove and refit if my car needs to go too dealer?
6.If i cant get an HKS one whats a good alternative and any example videos or sound files of noises? If not how does it compare to the HKS?

Cheers guys

Is there any point to a dump valve other than the noise?

Does it make any noticeable difference to turbo lag or anything?

will do

re the running issues I've looked into this and I think I have a cure. mine had that problem with the Forge one I had but it went away when I fitted an air filter which was strange

I was reading up on the VX220 forum as they are a car I have heard have bad problems running a second dump valve. I think the answer is the airflow meter anticipates a certain volume of air passing it when the throttle butterfly shuts, as a second valve removes more air than the airflow meter anticipates it feeds this back to the ECU and causes a blip in the fuelling, or maybe it opens the butterfly back up??

So basically a blanking plate for the standard dump valve should completely cure any minor blips by restoring the airflow meter readings to normal. I have one on the way from forge which I thought I'd try on mine as the wooshy sound from the standard one does my head in a bit with the air filter on. Obviously forge have had this issue with theirs as they supply the blanking plate with their kit. Its an eye watering £25 quid on its own though so if theres any demand for them I'll look into getting some fabricated

I've ordered one off forge uk should be here midweek next week, they offered next to no discount on them though so people might be better off contacting forge dirtectly to order them, but when its fitted I'll post some info to let you know if its helped

Is anyone running the Forge kit, I've read that they are the best dv's available. Just wondering whether to swap mine for the Forge setup

forge are good basic valves but they arent a patch on the SSQV, the ssqv closes instantly after discharging, the forge tends to pass for a bit longer than it should

Dump Valves release unused pressurised air, as it's released, spins the turbo causing more oil to flow through it, prolonging the life of the turbo. Easy! obviously there are exrtemities as to how much it hisses to the amount of good its doing, set it up right its a good thing.
