i have a frst and fitted a bailey dump valve to it but it is realy quite were as my m8 has the same dump valve and is louder he told me i needed to increase my boost pressure at the actuator but can anyone tell me how to go about this cheers

[dangerousdave]

you have to turn it shorter to increase boost, but unless ts not standard or you have some bigger inj and chip theres not much point as you cant go much higher than standard without risking damage!

[Dereksjoint]

Standard boost on a Fiesta Turbo should be around 7psi mate and at that you should get a very nice Pttttsssshhhhh from the Bailey Dump Valve. Like Dave pointed out though you really don't want to go much higher than this or you'll risk running the car lean and blowing up the engine after a few miles.

It can be quite awkward getting into the Actuator to adjust it especially if you're turning it a few threads then taking the car out for a test only to find it needing more so back in and a few more turns ect ect. To avoid this you can fit a Bleed Valve, the bleed valve gets placed between the Actuator and the Compressor housing side of the turbo. Simply cut the Vacum pipe that go's between the compressor housing and actuator and place the bleed valve in the middle. Make sure you tie wrap all the cut ends of the pipe to stop them coming off.

The more you open the bleed valve the more boost you will gain and the more you close it then the actuator will take over again at it's setting. The bad side to bleed valves is people tinker with them thinking lets just crack that bad boy fully open but again the engine will last only a few miles.

What every way you decide to go you'll need a boost gauge to let you know how much boost the car is running

[jayrs]

what dump valve you got? piston or diaphram one?
i would check your boost pressure BEFORE trying to change it, you might have a leak somewhere

[xr2i_dan]

i have a piston one but i have a t3 turbo with an uprated adjustable actuator but dont no wot pressure it boosts at

[jayrs]

i would get a boost gauge in there mate see what presure you got.

although a twin piston one does work on a fiesta turbo, there basicly for the ERST, so you would want a single piston one for the FRST.
i would of gone for a diaphram one mate, well i did, and i did try a piston one but didnt like it 1 bit, that was a twin one i borrowed off a mate to compair the sounds
was back in the day they first came out

[xr2i_dan]

ok then m8 well i will see what pressure it boosts at and see if i can get a diaphram dump valve cheers dan

[jayrs]

wouldnt change the dump valve just yet mate.
i would get the boost gauge fitted and see what boost your running first

also where have you got the vac pipe plumbed into out of interest?

[xr2i_dan]

i have got it plumbed into a boost gauge but i doesnt work very well it does not give a good reading

[jayrs]

that coming off the side of the inlet yeah?
might be worth checking the pipe hasnt split somewhere, i know some vac pipe can split where its forced over such large nipple

[xr2i_dan]

yer its t of the inlet vac pipe m8 ok i wil check and then go about getting the chip and injectors

I have a fiesta rs turbo and just put in a T3 setup aswell.. i just bought a bailey venturi dump valve for my car.. fitted it on and was hoping to get a really good response as they are suppose to be louder then the stndard ones.. turns out she aint loud at all even when i put my foot down on 2nd gear i can just about hear the dump valve kick in.. before putting the dv in my vacum pipe was connected to my ford racing boost gauge and im not sure if this is right but my car when i drive her wont even reach up to 0 on my gauge so hmmm.. not sure if thats reading right... i have just bought a boost controller i dont know if that will make any difference to her.. i dont want to burn my turbo out as i just had the car rebuilt lol.. she does idle a bit abit aswell.. under revs half the time...

any ideas..

cheeRS

[jayrs]

if its not building boost, you wont get no sound, i would remove the dump valve and see if your getting boost, if you are, somethings not right with the dump valve, if your not, then its a high chance theres a leak, or the actuator is opening far too soon

[rsturbonutter]

How have you connected the vacum pipe have you made a t out of the one to boost gauge. I used to have a venturi some years back and it was very very loud indeed. Its what put me off them to be honest. I used to scare people at the side of the road when dumping my clutch

[jayrs]

whats wrong with that

mind you, i guess the older you get, the more silly you look, but on the other hand, the question is: do i look bovered

[rsturbonutter]

There's nothing wrong with it fella but i live in small part of the world called the rhondda valley and everyone knows everyone and i was fed up of people assuming that i drive like a t##t just because my car goes pppssssssssssssssssssssssssssshhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh. Then you have kids flying round in their 1 litre clio's etc flat out and nobody bats an eyelid because you can't hear the weedy little engines. I also prefer the chatter to be honest

[jayrs]

sounds like the isle of wight, went into morrisons once (was safeway at the time i think??) anyway was doing at best 15 mph, some c0ck gobs off, you wanna be on a race course or some crap like that, gave him both barrels in front of the inlaws as they had just got in the car and went on my way, but i knkow what ya mean mate.
but i never let it bother me, i still dont, but with ref to the c0cks in the 1 litres, couldnt agree more, there the worst,

[dips7758]

Hi guys its been a while ... I'm back its a good 8months if jus started the rs rs up and cleaned her n took her for a spin I put my foot down I can still juSt bout hear the dump vvalve kik in .. is that an actuator problem then...[ERRR] now im loSt...

[Mattious]

Is it a piston or a diaphragm dump valve ? Some
Times the diaphragm can perish/split ? Have you checked this?.

[jayrs]

What's the boost pressure?

[dips7758]

Hi guys its a piston dump valve...jayrs I haven't connected my boost gauge up as I haven't got a t connector... from the dump valve I have connected the top small pipe to the efi unit n the left..still nothing...

[dips7758]

What's the boost pressure?

Hi Jay..if connected my boost gauge up..soon as I start the car the boost gauge reads just under 15 on vac..soon as I accelerate it it hits just up to 0.. on the gauge...haven't driver her just yet as exhaust is getting welded.... does this info give you any ideas on where its going wrong...thanks....Dips

[georgiocat]

If it sits just on 0,then it doesn't build boost...Check your boost hoses for split,or loose clamps.If all the hoses and connections are ok,then chances are that the actuator spring is weak,or the dump valve is not sealing...although most of the cases,it is the actuator,had the same problem in the past.

[jayrs]

As above, that's why I was asking

[georgiocat]

As above, that's why I was asking

Well,I guess we have read the same books Jay

A rough solution to alter the boost pressure the actuator works,is put a manual boost controller to the wastegate line and adjust it till it boosts at the level it should,but it will drive like a bag of sh@3t,since the spring has lost it's characteristics,but it can work for testing purposes only.There is the solution of completely disconnect the boost line from the actuator to test it under extremely cautionous conditions,but you must take great care and alway look at the boost levels on the gauge,since turbo is completely uncontroled in that way and will boost till it;s limit.Not good for your engine so just DONT DO IT!I can't stress it more,lol,just mentioned it as one more way.

[jayrs]

Years of owning and working on many turbos mate lol

As for the response, well I have nothing to add, you have covered it lol

[georgiocat]

Years of owning and working on many turbos mate lol

Well,the only turbo I ever worked on,is mine and that's after 2009.But owning a sierra and 3 escorts since 1990 till nowadays,and all CVH'd with the dream of turbo them,tought me a lot My project now is to transplant the rst lump in the sierra one day.160 rwd hp sierra will be a toy to play all day! But enough with hi-jacking,back to reality. lol

[jayrs]

Self learning is what its about, I had a head start thanks to my dad but I soon flew lol

If your going to that hassle, ZT it

[georgiocat]

Thought about it,but you must declare whatever engine transplant you do,here in Greece.Sometimes you can't do it for engines that Ford had,ZVH is not an engine from Ford,it's a hybrid,so,not gonna happen.It is illegal.I almost had troubles being legal with the CVH in mine.Keep in mine I had CVH before.LOL!!!!The theory is,that since the car never came out from the factory with that engine...you can't put one.Even if you do a full modification and replace suspension,brakes,etc etc,you will be illegal in most if not all case.There is a procedure for doing it legal,but the cost and paperwork is so high,that nobody even tries it...I live in the wrong country!!For many reasons!!Lol.

[jayrs]

My mistake mate, I forgot about that.
What if you imported a modded car? Or can you not even do that?

[georgiocat]

Nope,not even that...only what is..."factory oriented" if i can say that in that way...best case scenario is the transplant with an engine no more than 25% of the displacement,or the hp it had initialy.Also,the exhaust gases of the new engine must be equal or less then the engine the car had before.Finally,even if you manage to do all the above,you must have a certificate from the factory that the chassis and all the mechanical and ancilaries,are under the factory standards.But who's gonna sign for something like that,in an authorized Ford garage?Here they claimed that I can't transplat the lump in my car...because nobody done it before...

[jayrs]

FFS mate I feel for ya

[georgiocat]

Yeah,thanx...well the keyword here is money...the more papers you need,the more money the govenrment will take from you.Lol.

[jayrs]

Lol
