dump valves

[johnny]

can anyone tell me the low down on dump valves for the 1.8 t ibiza

i run the 007 forge no problems with it but its so quiet ie recirculating....

i now run a boss performance one awesome noise the same valve as langly run on his ibiza in max power as a mag car now if a mag car can run one why are we always advised away from them .........................?

 

[WeeJase]

because they sound like a bus?

 

[johnny]

a bus i think u find thats air brakes sun shine !!!!!!


So what do you run ???? skun

 

[WeeJase]

of course it is,but it sounds the same,try a search for the reason why recirc dump valves are better on a 20vt,i personally drive a skoda octavia vrs with a forge 006 dump valve as the standard one is crap on a chipped motor,as its diaphram rather than piston type that i have /many others use.

my mum used to call me sunshine when i was 5,thanks for the memory

 

[johnny]

i know why i have uprated my dump valve i want to know why we use recurculating ones has anyone had problems with blow offs does anyone else have a boss one i have run both forge 007 and now the boss

Cant quite see the link with dump valves and SCN merchandise but as Jason said just have a search as its a very common question.

I'm running an Atmospheric DV on my non-chipped Cupra..

 

[didgy2]

just put the gfb one on,if it works well done,if not then its only your time/money
wasted anyway.
if you really want the whoosh noise you'll put up with it stalling and stuff anyway

i think you'll find he never ran any vag-com type software to check for fault codes,
and when i heard it, must say tick over didn't seem very smooth.
he did run it for 12 months tho,shame he didn't do any power runs before/after
which is what they should do when recommending parts etc.
(he was running revo tho so not a bad car)


cant ask him now tho cus he gave his car away and is sticking
with his scooby

supprised the "winner" of his car hasn't found his/her way here yet

to all the people who say 'its ok'

how's the air fuel ratio
is the car overfuelling
what are the long term effects (and I don't mean you've run it to work & back for a couple of thousand miles)

There is a VERY good post that I need to dig out that explains it very clearly why atmospheric DV's are bad for your 20VT

I'd like to see the reasoned arguement against that

I know Robdon has tried about every type of DV on the market fot the 20VT engine, and he must have spent a few quid in the process, even his latest HKS one is causing a few issues;-

But he is still trying to find a solution.

Personally I wouldn't spend money making it go faster, then fit a part that sounds good but slows it up and could cause long term issues.

My head always hurts after reading Max-Torques posts

It's the turbo reliablility issue that would worry me the most. you don't want the turbo to have any bits come off & either fly thru your cat (exhaust side) or fly thru the inlet side into your engine.

your mates will respect you big time when there's metal in the piston causing a camblet failure (or worse)

So would I

I did have the car cut out on me.. but i needed to tighten the valve on the DV .. seems to be ok at the moment.. touch wood!

I haven't got a Cat on my Cupra.. She does occansionally pop'n'bang though..

Had it on VAGCOM?

and checked for more than fault codes...

 

[CupraLee K1]

Nope.. Don't know any1 with it..

Unfortunately got to save for a holiday.. Otherwise Re-map would of happened now.. and Atmos DV come off and Re-Circ gone on..

Damn, I missed that superb post the first time around. That'll teach me to auto-ignore most threads about "chav-alarms".
