dump valve
what's everyone's view on these things?
I'm getting mixed reactions , some people say if you've got a turbo let people know about it and other say there chavvy and will bog the turbo down and make it run like crap unless I get it mapped etc etc I'm on a budget by the way as this is one of many toys my missus is gettin cheesed off with :-)
I've got a my99 type ra limited which is tottaly standard apart from I've stripped it out as its only for the track .
would this fit and work ok?

I've heard that the louder they are then the more bhp you'll gain.
My mate Dave - (see pic) -
- from the rose and crown fitted one and he kept up with a 450bhp evo.
Wicked !!!!
Seriously, you've got a nice car there and the fact its standard makes it bloody rare and desirable. Don't wreck it by fitting something that offers zero benefit and can actually do your car harm

Well i took the advice and did a Advanced search on Dump Valve ... as i always been a fan from previous cars (Rx'7s and Pulsar i have owned) but i must say after reading a 4 page thread ... i am well and truely put off getting on for the scooby. Seems there "can" be so many problems unless you have it mapped or set up correctly. I was just goign to chuck one on !! Not now ... spend your money on fluffy dice i have.

this is what I mean always mixed reactions, thanks for the kind words on the motor only paid 1400 for it but the body work is a bit tatty so will prob respray it.
after stripping it out (serious amount of weight!) she goes so well but as it's my first turbo car I'm just a bit :-( that it doesn't ptshhh lol
maybe ill leave it , got track day Monday so see what falls off it and go from there
one more thing, can you not get recirc valves that still make a sound put dump pressure back into the pipes?

You can get adjustable ones where you effectively have anything from 0-100% as VTA or recirc.... or any ratio in between. So you can alter it to suit your mood (prob not great idea if you still have a MAF).
Or there are fixed 50/50 VTA/recirc ones.

an alternative is getting a bullhorn and keep the window open. Everytime you change gear just scream "listen to my awesome car, you *****. Aint it cool how it goes "tsssssssss""
All joking aside I would rather do the above than put a dump valve on my car......they are called dump valve as the original company thought '**** valve' would not take off from a PR view

To the OP I'd advise updating the air intake filter or system and remapping, you'll get more of a snarl, a hiss when you take your foot off and a performance boost.
You won't see much benefit from a dump valve even if some of us think it actually sounds cool.

why go round taking the **** unless your going to help
its not up the chav police to decide whether he gets a dump valve or not
nozzza
have you thought about changing the intake?
i spent a few hours yesterday reading how you can get more ptshhh from the OEM valve

appreciate the different angles here guys, Im just a big kid that's all ,this car is never gonna see legal tarmac again so I just thought spending a few quid on making it sound meaty would be funny, it is pretty rapid as is and is super light, I don't know what these ra models are different but its def lighter than my bros old one.
I think intake is a good idea! the oem induction has got a sensor on it tho, does the aftermarket stuff get around this somehow or is it just an end piece that goes on?

The OE intake contains the MAF sensor. This CAN be damaged by induction kits, either by too much vibration, or by the oil from the coner getting onto it, or by the cone not filtering well enough.
A failing MAF can also lead to engine problems...SERIOUS ones. VERY expensive ones.\;9
Seriously mate, forget the daft noises and maker it go better, stop better and handle better. You'll be far happier.
We take the **** because it's often the only way to get a serious point across.
As for chav police, grow up: the OP asked a question, it got answered. You don't like the answers, don't read them. It's a forum, dude: that means we express opinions, and SOME of us state facts.

I ran a Forge VTA on mine for years with no problems atall even at 440BHP. If you want one don't fear the chav police just go for it but is best mapped for & gives no advantage over the standard recuirculated valve. I personally only found it annoying around town & am about to go dump valveless on an MD321T with a remap.

A VTA dump valve won't damage the MAF but an oiled filter like a K & N can. Lots of people still run them though, but there is certainly more risk to what is already a fragile MAF.

your welcome to your opinions and i was politely pointing out that they should form no part of his decision.
i have my opinion that there are lots off chav police on this forum but you didnt seem to like that. a little hypocritical me thinks

God damn, so many dump valve fanboys in such a small area! My view is if you want to sound like a braking bus then go for it, but be aware that unless you run a MAFless setup your car will run rich on the gear changes, greatly reducing the responsiveness through the gears and slowing you down overall.
Also that rich mixture will reduce the lifespan of the cats (if you have any) and can glaze over your cylinders.
still want one?
