i am buying a series 2 rs turbo and it does not have a dump valve and i want to fit one when i get it. does the engine need to be set up on the R/R again for this? or any other moddifications to do so
thank you

 

my oppinion dont do it mate

your car will prob need a tweak some where along the lines after fitting one cause it will have a rough idle

 

cheers mate

any1 else got any suggestions

 

Just dont do it!

Seriously though mate, Chatter sounds much better

 

They are easy to fit mate i'am sure that it will not need setting up after you have fitted it. I got mine from a company could NOMAD RACING there number is 0115 9550474 and they are in Nottingham the man you need to talk to is Martin. I got a twin piston on of them and it sounds shit hot mate. HOPE THIS WILL HELP YOU FELLA

 

aslong as its twin piston it shold be fine, otherwise get good at right foot throttle control you'll not need a set up but it could be worth 1 neways if its not been done for a while

 

cheers fellas ill look into gettin a twin piston dump valve

 

Bailey twin piston is the one to go for if you must have one but I would recomend against it.

If it's your first turbo car though you will prob want one for the novelty factor, nowt wrong with that

 

yea it is my first turbo, what is "chatta"??

 

aint even read post or replies... all im goin is...




NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO



no dump valve.... y wud u wanna give car an air leak???

 

this sounds really stupid but this is my first turbo and i am not sure what "chatter" is, is there anyway to explain it?
cheers

cheers fella they were great. i dont think im gonna bother with the dump valve chatter is much better

 

 

Told ya! lol

 

Lets face it when we all had our first turbo we all wanted a dump valve but you grow out of it .

 

just one more thing, do you have to run over a certain boost pressure get the chatter the 1 im looking at buying is running 15psi is that enough?
cheers

 

im on my first turbo car and i don't have a dump valve. they are so annoying and pikey.

i get plenty of chatter at 15psi mate, you won't be disappointed.

 

thank you all for ur advise
ill be sticking to chatter much better than a dump valve
cheers

 

Not technically an air leak, but they do cause a lot of people problems.

My opinion also don't do it

 

Do you actually know what makes the "chatter" sound m8? I wouldnt wanna do it to my turbo anyway, prefer to try and prelong the life of the turbo than potentially shorten it by having a bit of gay "chatter".

 

isnt it the waste gate that makes the chatter

 

It's the sound of the compressor blade stalling, in other words, what you hear is the sound of the turbo being forced to stop instead of being allowed to carry on spinning, put's unnecessary stress on the turbo.

 

I ran a dump valve on the general for a couple of years with no problems, then, after a setup it started chattering, so flogged the dump vale on e-bay for Ł75 I think

 

my last dump valve got jammed when the spring lodged itsself in the way forcing the valve to stay open, therfore my car wudnt tick over just kept loosing air and staling lol. they sound aight but the chatter is nier

 

Don't do it mate. Mine had one on when I bought it and taking it off was the best thing I ever done. Car drives so much better.

i didnt think you could get chatter on mfi

 

Sometimes you can hear it but its not as loud as an EFI car

 

you will get some "chatter" on MFI but it is nothing compared to when running EFI.
some people will say "dont do it" and some will say "do it". its your car mate and your choice!

 

What is it in technial terms then ?

Most valve/s i have seen (95%) is open at idle which leads to air leaking out the side of the Valve.

Now you explain.
1) how that is not and air leak.
2) whats the technical term that we dont know of?




Dont worry Steve im sure you will be set straight soon.

 

PMSL someones got their fucking toys out the pram again

Time of the month???

Girlfriend (Boyfriend???!!!) not putting out??? (On the assumption you even have one)

Mummy grounded you???

Or you just being an immature cos you got proved wrong in that other thread where you advised snapping parts over doing it the proper way

Chill out and grow up

 

are you going to answer the question or avoid?

regards

 

Just doing what you do best

 

 

So you'd recommend running a dump valve is safer for an S2? and will PREVENT problems lol?

Puts minimal extra strain on the turbo agreed but keeps pressure in the system. Running a DV upsets K-Jet and as said effectively gives you an airleak.

 

Sorry is that a telling off

 

Take it as you like

I found your reply towards jano a tad OTT.

 

Mines got a bailey twin piston, runs with no probs at 230 bhp, but doesnt the AFM muffle chatter?

Not heard chatter on K jet before

 

Fair do's

Sorry

 

The flap is the reason yesyou cant usually hear chatter on MFI cars, somehow some people get them to do it though, although apparently not as loud as an EFI car for obvious reasons.

I think chatter is mainly heard on MFI cars when higher boost levels are run......
