I've just bought a dump valve relocation pipe and bailey dump valve is it just a matter of fitting it or do i have to do something to the existing dump valve on the turbo
any help

 

You need your own section on this site, for the amount of questions you ask!

 

 

You should have blanking plate to replace the exsisting one by the turbo.

Yes you'll have to blank off the original one, by taking the three bolts out, and inserting the blanking ring.

 

As above, but can you confirm it is a DV30 isn't it?

 

Just get one to fit in replace of the std one!

Lot easier and makes it still look factory!

 

can you not just disconnnect the standard one and then fit the bailey ????

 

I did that and it works perfect and as I have air con getting the dump valve to fit on the cold side is a right pain

maxest
better to ask tho isnt it or else i'll never knows

 

so does that mean you can place a bailey one where the standard one was and run it to athmosphere instead of running it back into the air trumpet to the turbo ????

 

No bailey don't make one to fit direct on the turbo but collins do.

steve

 

so is it ok to run the dumpvalve to athmosphere on the warm side of the intercooler??????????????????????????????

 

Are you sure, mine had a bailey one fitted directly to the turbo, as does bigpower...

 

there website or their catalogue doesn't list one

steve

 

can anyone give me an answer on the last question i asked"can i run a dumpvalve to athmosphere on the warm side not back to the turbo to athmosphere ????????

 

bam, not on a small turbo Escort Cosworth, venting to atmosphere causes fuelling problems because it's air that has been measured by the MAF sensor.

 

i used to have a collins one when i had my small turb,but it didnt idle very well with it fitted

 

do u need a twin piston one then

 

You need to use the recirculating dump valve on the ST Escort

 

but if i block the old dump valve off then relocate it using a twin piston dump valve it should be rite yeah

 

I don't know, is your dump valve the recirculating type or one that vents to air?

 

vents to air

 

You cannot use it on the ST Escort then. The air which it releases has been measure by the MAF sensor and if it does't stay 'in the system' then the ecu thinks the engine is getting more air than it actually is and over fuelling occurs. Lots have tried normal dump valves and had poor idling issues because of it. You can only fit a recirculating dump valve such as the Bailey DV30 on your car.
