i 'duznt'!

nicorsts1

Nope, well rid of mate

turbodan

the one that came with my car is IN THE BIN they run properly without them, MFI was not designed to have air leaks

Oranoco

I have a drawer full of old dumpvalves. Even at 25psi mine runs without one. Would rather walk than have the car sound like a bus

juffer

i use one. i was under the impression that it stops lag and turbine stall.

stuart collins

i use one cause i run a Ł1500 roller bearing turbo at over 2 bar of boost so it might prolong turbo life i will put up with the bus sound

when you gonna be ready again stu?

T28 RST

There was one on my car when i bought it 6 1/2 years ago, i sold it soon after, then a couple of years later i felt the urge to buy another

Sold that one a few weeks later

Dump Valves are rubbish, only use if really needed.

Ahhh don't be so hard on them poor little dumpers...

I've got one aswell. Haven't fitted it at the moment but I will certainly put it on the car again next season. My mind seems to change how I think about them like every two weeks. Either the bus brake noise makes me grin for hours or I just feel embarassed because people will think I'm a chav. In the end there are far more cars with even more embarassing dump valve imitation things out there...

sas

I use one, but its only a small one!

Its just for safety, dont want to give the thrust bearings on the turbo a hard life.

S.

juffer

so is it eithe run a dumpvalve that sounds gay or dont run one and damage the turbo?

Šhatter Box

the only dv to work on any mfi rs is the bailey twin piston

Oranoco

It doesn't damage the turbo that's just marketing hype to sell shiny shit to stupid people

originalcabbie

I have recently removed my dump valve due to runing problems (major rich when dumping!) if you think about it the fuel is matched the air then the air goes away! wooo rich running car!

Turbocabbie

How many Garret turbos are you aware of that have been damaged due to not running a dump valve
What damage do you believe can be done by the turbo stalling on the amount of boost you are capable of fueling on a RST ?

If this was a problem do you not think ford would have fitted dump valves to the RST themselves.
The piston style dump valve was actually developed to overcome the running problems caused by running a normal diaphragm based dump valve on the RST which causes erratic idle.

bezo

run a GReedy bov on the kombi, works a treat

1.9 xr2 on 40's

urrr lots of manufacturers do fit them, just recirculation to stop the noise including cossies i beleve (not sure but think)

mentalasanything

I have one on mine, doesn't cause any problems at all, definately helps with the lag between gear changes (As it's meant to!) and I quite like the sound.

No I'm not a chav either, it serves a purpose for me!

Imitation BOV's are gay tho

Fiecos Dan

i do.




All GT turbo's are only garrentee'd if dumpvalve and water cooling is fitted, due to the failure it will cause from not running either on any engine.

and on carb turbo's, if no dump valve is fitted, over fueling is a big issue on over run.

Oranoco

He said Garret Turbos not GT series turbos. I'm yet to see an RST Garret turbo fail as a result of no DV at any boost pressure.

On an RST they do cause rough running and from experience tend to make the car more laggy. imho you would need your head reading to even think about putting a DV on an RST.

Some cars do require there use like big turbo Escort Cossie's as it upsets the fueling running without.

I know my A4 must retain it's recirc valve and the use of an atmospheric DV isn't recomended (not that I would conmsider it anyway).

Fiecos Dan

He said Garrett turbo's, not only garrett 't series' or not inc 'garrett GT series'.

Oranoco

Fair comment reading again

lewis_lisa

i run a bailey twin piston on mine as it was there when i got the car.
never had any probs though sometimes the noise does annoy me

T28 RST

Lewis hows the car going, i saw that you got another bottom end fitted.

Did you go and get it set up so you dont have anymore mishaps

O and bin the gay valve

TuRbO-CaB-LaD

got baileys twin piston also

Turbocabbie

Fair comment But in reality their are few RST's running GT series turbos and I made the assumption we were talking about the standard format turbo's..

My error though as assumptions are pretty poor things

Turbocabbie

Yes I am aware that many vehicles including the Focus RS have recirculation type valves as they require them for the type of turbo they have, but as stated Ford never fitted them to the MFI RST as they were not and are not needed

lewis_lisa

aye m8 car is ok not had it back out so still need to get a set up but will wait till next spring as i wanna do some other wee touches to it need a new oil pump aswell

you still got your car m8

Dump valves are gay.

I thought this had been underlined ages ago!
