Right, im quite sick of the noise of the dump valve however, when i asked Stu a whileback to remove the dumpvalve, he confirmed that the standard dump valve had been removed so advised not to take it off.

Is there a 'silent' dump valve i could buy? As i quite like the sound of loud as fcuk chatter!!

 

If you want loud chatter than just blank off where the dumper goes, simple.

A silent dumpvalve will partially or totally remove chatter

 

Will this damage the turbo though??

 

No i it wont damage the turbo, unless you are running a high boost T34 or a T4.

I believe the reason they were originally fitted was for Homolagation reasons and
to rid the noise of the chatter............


Al.........

 

I don't use 1,got sick of it,and the "chatter" sounds much nicer IMO. Apparently it's got fook all to do with the wastegate tho,it's the air getting chopped up or something clever.

 

Mmm but does a turbo have some sort of protection/dump valve on it as standard? Maybe Stu can describe better what i mean??

 

I have No d/v or recirculating valve on mine and it chatters its nuts off

 

Will it make my battery run flat though Tiff??

 

Oh, and can i just use a broom handle?? PMSL

 

When I removed my dump valve it killed the turbo !!!

It was a 450 bhp roller bearing turbo and it bent the shaft.
It happened between gear changes on low boost.

Completely my fault for listening to bad advice

 

Right, if i blank the dump off, what do i do with teh tubing that comes from the inlet? blank that off?

 

ford didnt fit them just for fun, ive fitted a piston recirc type on the cold side then reconnected it to the intake hose as in a rs500 set up, doesnt sound too bad at all now

 

 

Remove it if you wish, but get ready for stalling at every junction and overfuelling problems galore

Ignore this lot who havent a clue what they are talking about*












*Joke chaps.. chill

 

On low boost? Bearing in mind a lot of turbos handle it no bother even at mega boost id put that down to bad luck or a shat turbo rather than no DV.

Aaaah, so his is a small turbo with an AFM then!

Nope, you NEED a dumpvalve then, bloody stoopid AFMs...

 

Yes,a wastegate.

 

eh? wastegates to control boost, which is owt to do with the function of a DV.

 

Tongue in cheek remark mate. I suppose you could argue that a wastegate is "some form of protection" cos without it working the turbo won't last long.

 

 

I wont remove it then!! Is there no way i can get loud chatter??

 

Yes pal.
Secs S8, marrelli, Pectel T6, Autronic.. the list goes on

 

ok what is afm

now im lost

 

How much!!

 

AFM = air flow meter...

 

Air Flow Meter mate

 

Beaten too it by rainbird

 

Air Flow meter

 

I shall mostly be buying some nice hoses this sunday to be able to remove my DV

 

afm is a air flow meter,like a rst a restriction from the turbo to the air filter.measures air flow to give another dimension to the mapping.

 

I got a d/v blank if u need 1!

 

Anyone know if the standard re-circ on the Focus can be removed?! I've got a cone filter + you can hear it pretty loudly, wonder if I could get chatter?! If so where's the best place to get blanking plugs?? Central day?!

 

i got a blankin plug nath!

can bring it with me to pod!

 

Cheers Lewis but don't worry about it. Want to get conformation/some elses experience if it's safe/possible on the FRS first, then I'm sure they're only a few quid from Rainbird!

 

If FRS has no AFM (im sure itsa MAP based setup yea?) then you can do it.

Have they a recirc one as std?

 

Steve, yes it has a re-cird std + has no AFM (well AFAIK)

I'm still a little concerned about turbo life though!

 

My SX chatters like a monkey on crack!

 

Nath, your turbo will last for ever, as it never sees any boost anyway

 

hi all, i normally dont even look at posts reguardin dump valves, as im sick of all the peeps talking crap iv had one of stus dv on for years and never had any probs or damage the simple fact is if it dident have one fitted a standard its up to you weather u fit one or not..simple or if you have erst fit one of stus electronic box,s ..and dont fit anodised
i talked to the guys at castle about it and he said d/v were first thought of by ford, and said when collin mcrae was rallyin thay were devised so he cud change gear faster.. thus gettin rid of the back pressure and bein able to change gear faster so people should look into why thay were first invented!!! instead of slaging them off, if you dont like them take it off, or if it was made with it on you should leave it on and not vent to atmosphere whitch is what ford did
i have a switch on my erst and can turn it off or on , and i think it deff goes thru the gears better with it ON!!!
