Just a quick one the top boost pipe mind has a dump valve does anyone no where I can get a blanker plug as don't want the dump valve no more

25mm blanking plug off ebay depending on what size the hose is? Is it a bailey dump valve if so should be 25mm

cooksters

Yea great guess it is 25mm ok ill have a look on there thanks

Also will I not need to do some thing with the boost pressure release pipe that comes off that dump valve or is there another one some where

The vac pipe going to the dump valve will probably go to a t piece near the inlet manifold this can now be removed

cooksters

Oh I see what ya mean and can just take that pipe straight to where it needs to go now. thanks for that got a cossy cone fitter on there so gonna see what the chatter is like as the dump valve ya can't even here it ice one

Auto specialists also do em

Right took dump valve off and there was a t piece the other part of the pipe gos to the boost gauge by the looks of it .That now don't work cause no dump valve and there is hardly any chatter at all just wanted to make sure what I have done is right

You need to only remove the vac pipe to the dump valve, you'll still need to have a vac pipe to the boost gauge.
So if you remove the t piece, you'll need either a straight through connection to join the two pipes, or a new piece from the manifold to the gauge.

And if you've got an escort Rst on mfi, you won't get chatter as the metering unit has a flap in it that closes!

Sorry I didn't put that down mind is efi I converted it about a year ago and I have done that just put a connector in so then gos off to boost gauge that's ok then least I no that's ok. Maybe not getting a lot of nice due to big cone filter which I had to have to do the conversion and running standard boost

This will open a can of worms, but surely running a dump valve keeps life a little kinder for the turbo, as opposed to running without one with increased boost levels. While the noise produced from the compressor is great is that not the sound of the turbo attempting to stall due to the air having nowhere to go?

While I am all for great noises I also try to be one for longevity .

cooksters

Yea I no what ya mean but mind is complete standard efi engine bar the t3 turbo off the escort and running bog standard boost so should be ok up to a certain level of boost not amazingly clued up on this stuff to be honest

Yes it will last a little longer..... enough to worry about vs losing the bus air brakes sound, probably not?! lol
