Not being funny but bleed valves are a total load of shite and a complete waste of time and money! It's an amatuers way of setting a car up

 

Another pub expert enters the affray.

 

 

O.k what's the advantages of a bleed valve then??

 

Oh dear here we go

 

 

No, lets play the game the other way shall we. You please tell me the dissadvantages, and the reason that, in your expert opinion, they are, and i quote:

Not to mention why:

 

I dont claim to be an expert but in my experience they are a total load of shite, my first turbo was fitted with one when i bought it and other than being able to piss about with the boost yourself whats the point, you shouldn't need on. I had it taken off mine, had a decent chip put in it ad it went like a dream. So please tell me all the advantages of a bleed valve

 

smart aRSe, and what if you want to be able to adjust your boost and can't afford an expensive ass electronic boost controller?

Do you suggest carrying some spanners and adjusting the actuator everytime

 

In short it helps the tuner from getting under tha car and sorting it properly. Time saver type of thing

IMO the best way to adjust the boost is via an AMAL valve with decent setup jets inside to control the boost spike and hold etc..

Thats the best way without spending money on after market stuff.

Regards



P.s good thread.

 

Stu don't even bother mate, just think after you've typed a small essay and made him look stupid you will never be able to get that 10 minutes of your life back!!

 

smart aRSe not a good idea to argue with Stu mate


he's forgotten more about RS Turbo's and Cossie's than anyone else ever knew about them in the first place

 

Oddly enough, ive just done one on all forms of boost control for this months fast ford, 2500 words of it, so please buy it this week and save my poor fingers.

In essense, bleed valves are fine in teh correct hands. What do you think an amal valve is? Its a 3port bleed valve controlled by 12volts instead of a screw.

Jano, you know very well that most Rs Turbo amals dont work anymore and the owner cant always afford the cost of a new one plus fitment.

 

Stu @ M Developments does it count if i go to the newsagents, read the article and then put it back on the shelf and walk out?

 

Think I might purchase that for some gooood reading material, haven't read either PF or FF for a while... prefer passionford lol

 

lol you may see me walking into smiths with a chair this month

 

Well i personally would be really happy you at least made the effort.

Id be happier if the sales figures went up now i am writing for them, if only to justify my ourageous fee, but i would be happy with your noble effort's nonetheless pal.

 

do you write in FF every month Stu?

 

aww I shall purchase it then

Stu, have Fast Ford had many letters or feedback bigging up your articles?

 

Yes Al, really enjoying writing technical articles professionally too. Its nice to chill out late at night in my office at home and just rattle away at the keys knowing thousands of people will enjoy it and maybe learn a little too.

In order:
June:
How a big turbocharger makes more power with less boost than a smaller one on teh same engine.

July:
How to read and understand compressor maps so you can spec a turbo properly.

August:
Fuel pressure. Whats its for, why messing with it can be deadly.

Summer:
Boost controllers. What options you have, how each type works and what are the +'s and -'s.

Next Month:
Spark advance, what is it? why do we need it? what changes how much we need?

And the month after that is underway now.

 

Simon tells me the feedback he recieves is great.

This is teh only topic ive put up and all seems well.

That is very true sadly. Good write ups in the mag tho Stu

Makes a good read.

 

Very kind, thank you.

 

some legendary advice on here at times
20psi boost bending valves is the hands down winner

worth a mention......

if the fuel line used on the bleed valve was rubber with inner braid, that wont ever swell up like the shitty silicon crap that people use because it looks nice, then hes fitted THE best part for the job, obviously this should have been securly fitted though!!!!

 

PMSL i remember that

 

No disresepect to you Stu but i've never known Ahmed Bayjoo to use bleed valves on any of the engines he's done the chips for and set up or Joe at GS

 

Is it just me or is Stu being taught to suck eggs by someone going by the name of "smart aRSe"

 

 

Sorry, missed your reply yesterday, just read back through it now looking for teh relevance of your latest answer and spotted the reply i had missed.

So i asked you:

And yor comprehensive and in depth technical answer to that question is;

Im guessing that you dont know why you hold that opinion then?


Then you go on to waffle about how "you" have never seen Ahmed fit one. Are you a stalker of Ahmed's? You would have to hang around a bloody long time to see him fit one wouldnt you, its hardly an everyday occurrence now is it. Blimey, ive done between 20 and 30 turbocharged cars this month so far, rangine from a Punto to a Volvo and I havent fitted a single one, but i remember fitting one to a Fiat Coupe 16v last month as the lad had driven from Portsmouth, his amal valve circuit in the ecu turned out to be dead and the job needed completing.

So, Erm, the relevance of your point is what? That if "You" havent seen it or "You" dont understand it, its a "load of Total shite"

Open your eyes fella, you may learn something of use to you one day, as for that matter may your tuners if they are responsible for giving you this distinctly unimpressive tuning education.

 

i didn't say i've never seen Ahmed fit one, all the people that i know that have one of Ahmeds chips in their car don't have bleed valves on 'em thats what i was saying

 

Maybe the amal valves all work on their few cars.

Seriously though, why not give this some thought.

Amal valve = 3 port bleed valve = good.

3 port bleed valve = total shite.


That is what you are saying, but you dont seem to know why you are saying it!

That Amal route does have an advantage on SOME cars, but not all, but no point going down that route until you have figured out where your basic understanding of teh devices is failing.

 

The difference here is the amal valve is being controlled by the ECU for closed loop boost control.. so no, it's not "the same as a 3 port bleed valve"..

 

Closed loop boost control, on Bosch KE Jetronic?

Sorry, it doesnt have that capability.

 

Bosch KE Jetronic doesn't because it's a fuel system

The ESC-2 does..

 

Must be the bloody heat, makes everyone suddenly think they are experts and want to argue.

The ESC 2 system that Ford used to control the ignition and boost side of the engine alongside the Bosch Ke Jetronic system that they used to provide the fuel control on the CVH Turbo does not have closed loop boost control. If you want to disagree with me any further, then instead of us just going to and fro, please provide some proof of your statement.

 

The ignition ECU on an RS Turbo isn't ESC II either though is it

 

Maybe i'm wrong then

 

Is that why experts use a pwm clamp on the map sensor then to avoid the boost cut rather than doing the chip properly?

The god complex is pretty offensive

 

Plenty of people use a frequency clamp on many many cars to great effect.
We still use them for CVH's if its a small spec, saves pissing about changing teh processor. They are used by us, HKS, APEXI, JUN to name but a few, on cars ranging from a Subaru to a lancer evolution 8. Funny they all work perfectly well, yet, since you have gone totally off topic with this bizzare redirection are we to assume you think for some reason that a frequency clamp doesnt work or is less effective than changing the processor byte? Lets hear why then...

Also, i guess you decided to drop the closed loop argument and try to sideswipe into a new discussion instead?

 

Sorry, totally over my head that one...

Off out to give teh car some abuse in the sunshine now, will leave you chaps to debate teh finer points of these antiques and see if you have discovered something new that nobody else has ever discovered over the past 20years.
