Difference between a bleed valve and a boost controller???
Ok so my escort turbo seems to have what I believe to be brass looking bleed valve on it, some people say that boost controllers are the same. Could someone please tell me the difference? Also is it easier to adjust a boost controller or a bleed valve? If I have a bleed valve and wanna run more boost should I replace it with a boost controller? Does it directly replace the bleed valve?? How do I know when ive more boost? Ive got a bar turbo gauge not a psi so how do I convert? Any clarifiacation is gladly appreciated....
Thanks Steve

1 bar = 15psi i think...
the ERST came wuth an amal valve to control boost...
id throw bleed valve in the bin and plug amal valve bk up IMO...
then get a pro tuner to adjust boost to wot u wanna run then get them to set up fuelin etc at same time!

Re: Difference between a bleed valve and a boost controller?
Boost controllers differ from bleed valves in that they control the boost electronicly.
Nothing wrong with bleed valves if they are used/fitted by a pro whilst having your car set up.
There will be a reason why your car is running the boost it is, whilst setting your car up(optimising the power) The weakest link in your spec will to an extent govern the boost and timeing that your car can run.
Dont go messing with your bleed valve. You'll more than likely dammage your engine turbo etc.

Why would you want to turn the boost down though?
Ok lets say you have a good reason.
You then have to rely on your boost guage (which may well be inacurate) to reset the boost and if your mis-judge things then you back into the realms of component failures.
So you pay good money to have your car setup by a proffesional, then decide that you know better that the pro.
I just dont get it!!!!
Nothing presonal, I just dont get the whole mentality of fiddling with something you are unlikely to know a whole load about, especialy when an engine failure can so easily be the outcome.

Boost controller
Ok so now im really confused.. I havent messed with the bleed valve as I realise what I could do but is it worth buying one of these £20 ones off e bay and will it be safer and easier to raise my boost a bit with it? My cars only running bout 10psi and I want to raise it to bout 13-15 safely. Will I be able to do this with the boost controller easily and safely???? Is it easy to fit?? Thanks

I dont think theres anything wrong with a bleed valve, the problem with bleed valves is that people get an uncontrolable urge to play with them and turn the boost up, then when it all goes wrong they blame it on the bleed vavle!!

Re boost controller
Well I am gonna go to motorsport developments as soon as Ive got the cash Stu as what you posted makes total sense.... £350 is a small price compared to a new engine... Just wanted to make the car a bit quicker initially till I can afford motorsport develpoments to sort it out.. You did my last turbo a few years ago and boy what a difference and what a bargain it is for the money.. Will see you soon Stu...
Cheers Steve

mines got a bleed valve but a local mech who was trained by a ford dealership told me it just tricks the management into running more boost! best leave it to the pro's. theyre the guys who know how to set boost. i dont think its something u shud set at the roadside!

I'm not a fan of bleed valves myself just because ive known that many people that have popped headgaskets with them turning the boost up too high.
If you're going to buy a mechanical in car item then you need another one under the bonnet to limit how much boost the valve in the car allows. If you have just an in car one you can make your turbo boost excessively high until the weakest part lets go.
Ive also seen numerous 2 connection bleed valves on RST's but they should have the 3 pipe items so they waste back into the air box and don't create a small air leak (hence why the amal valve on a ERST has 3 connections, and a FRST has 2)
Don't forget electronic controllers control the boost curve and help reduce lag where as bleed valves don't.......
zippyobrien i have an Apexi myself which i haven't used yet, but after speaking to numerous people im told they aren't all they cracked up to be, one of the biggest complaints being the reliablility, and on that note my mate also shipped one from Japan which never worked
Christian and Beccy oooooooo very nice
