I want to place a dump valve on my T25 escort.

Now I've bought a Bailey dump valve fitting kit. FK 12.

This kit arrived today

See pic:



But I saw another fitting kit, that's diffent, it got a blanking plate and mine doesn't have that.

See pic: (the Red plate that's the one I mean)



Do both kit's work the same? (all good or not)

I saw that the one dump valve that's recommend is for the T25 escort, is the DV 26 (from Bailey).

Does a DV 24 not work? And are the any other DV's who work as good as the DV 26?

Thnx

 

The small turbo Escort needs the recirculating type of dump valve, any other will cause running problems.

 

use the Collins one....bolts straight to the turbo....mine runs fine with it for 4 years now!

 

hi, mine doesn't use a re-circulating one and runs like a dream!!!!!(for years now) Baily type fitted near to fuel rail all prep work done by glyn at ggr leicester-i dont know how to put photos up but if you e mail me-glyn.williams@ntlworld.com i will post to you all the engine bay-

 

it doesnt need a recic one at all, just ove that does open at idel due to vac of the engine and let air in bypassing the MAF sensor - you need a twin piston type - similar to rsturbo.

the std small turbo escos has a recirc one built into the turbo thats what the blanking plate is for in the second pic, so you can relocate it nearer the throttle body - but TBH - ive removed mine altogether - you do get sick of the PSHHHHH all the time

 

If you don't use a recirculating type dump valve then metered air is vented to atmosphere. This will throw out the fuel and spark calculations, albeit fleetingly, not good IMO.

 

Thats why you need the Piston not a normal Dump valve.I've got the one recommend on the bailey site for the small turbo, they should know what works hopefully.
The recirculating type is just quieter thats all, it doesn't vent to atmosphere.
As Dave said the blanking plate covers the hole left by the standard one.The kit moves the dump valve to the cold side of the intercooler for reliability, apparantly.

 

the standard small turbo one is a good design anyway as it dumps the excess boost straight on to the compressor wheel,thus keeping it spinning,i wouldnt bother changing it personally unless you want the noise

 

Thnx for all the reply's

Last question, which of those 2 fittingkits is the best?????

Thnx again

 

you need the one with the blanking plate mate

i had a twin piston one on my old small turbo esc cos,and wouldnt work without the blanking plate...

 

Both fitting kits do the same. Instead of the blanking plate, the other fitting kit uses a metal piece (in the center of the small blue hose in your picture) to replace the spring inside the standard dump valve to keep it closed.

However, if I were you I would listen to sailorbob and keep the standard dump valve.

 

i never noticed that in the first pic lol

 

thnx for all the reply's guy's

I know what to do now
