Does anyone run one of these?

I do and am not happy at all with it. I set my -31 actuator to the advised 'half moon' base setting which runs the boost at 7psi with the pipe direct from turbo to actuator. If I then bring the TS boost tee into play and connect that up, on the lowest setting possible it runs at a peak of 11psi and drops to 9. I want about 14/15 at the moment, so one turn on the boost tee and it does not alter it. Another little turn and Im flying up to 20psi! I cant set it to what I want. Anyone else had this? Im thinking of binning the thing

Is that one of the MSD recommended ones? If so I thought they were ment to be as good as it gets for manual boost control?!

Lee Reynolds

Yeah hence me buying one mate but so far Im not getting it!

I just got one of these too. Fitted it but not tested yet.

Nightmare! I recommended one to a friend and that seems to work ok.
Maybe you got a hooky one, perhaps return it?

Lee Reynolds

Yeah looking that way mate. Gonna have another last go with it and take it from there!

What a whole lot of shite that's not needed....


Fit a standard brass bleed valve with none of that crap inside, and it will work better. infact a T piece with a restrictor would probably work better Lee.

Lee Reynolds

With MSD being renound Dave and recommending them I thought Id buy one!

Very true Lee, I don't see what's wrong with a good old conventional bleed valve though, all these boost controlers and fancy dawes devices like you have.

the ball bearing and spring are basically to prevent the boost acting upon the wastegate early, so the ball bearing stays shut 'til X pressure, opens and then the bleed screw sets the boost to whatever PSI youve screwed it to. basically a lot of bollocks that can just make it more difficult to set up IMO, good thing with a bleed valve is you fit it, adjust it and forget about it.

Ive got a turbosmart tee fitted, half moon pre-load on wastegate.
If i wind it all the way out, it runs wastegate pressure 7-8psi/0.5bar and i found 10clicks in (ish) to be about 0.8bar. Im mapping mine atm, so havnt turned it up anymore.
It does what i want it too fine, the only thing i can complain about is that it peaks at 1bar and then drops and holds 0.8bar, i'd like it to peak and hold the same figure.

no chance a manual bleed valve will peak and hold the same value, EBC is needed for that.

Well in that case i can't really complain...

Lee,
What car is it fitted to and what is the wastegate lift pressure set at?

LOL. You obviously have no idea how these things work mate or why we use them on some cars and not others.

Daviet

rather than just laughing it off...any chance you could explain why you do use them ??
always like to learn

Stu @ M Developments

You may have missed me also ask the owner some questions?
There is no point at all progressing further into it without knowing how its being used and what for mate, so tap subscribe and hopefully we will get there.

So how does it work? It's a bleed valve with a daft ball bearing held closed by a spring, which (apparently) stops the wastegate opening early (yea maybe on a really soft actuator)

other than "mildly modified turbocharged engines and factory turbo cars (which is pretty generic) " you don't explain why you use them on some cars and not on others?

What makes them better than a normal bleed valve? Why does it have a "restrictor nipple" when it's got adjustment already to vary boost pressure? seems daft...

Afaik, Lee is using it on an rs turbo engine which i'd assume was standard or mildly tuned.

Stu @ M Developments

Ok, so you have confirmed you dont know how they work, so lets leave Lee to answer and we can move forward.

vroooom ptssssh

I thought you'd esthablished that previously?

Stu @ M Developments

iTrader: (12)

I assumed so and you have confirmed it. Most people dont, and they are an interesting and useful tool compared to a standard bleed valve. Need Lee to tell me what he has so i can figure out why I told him this was the best one as he is the one who really needs, and has indeed asked for advice. There is therfore little point me spouting a load of stuff on his topic that is irrelevant to him.

We sell a few different types of boost control valve, but him having an RST makes sense as these are the easiest to fit to KE without having to mess about with the metering unit.

Lee Reynolds

Hi Stu,

It is as said and RST turbo setup in my RS1600i.

Basic spec is (if this matters)

Hybrid turbo
-31 actuator
Full front pro alloy intercooler.
Stage 2 P&P head plus cam
Running RS1600i inlet.
Chipped ECU.

Im hoping to have it setup and run around 190 even though I reckon 200 would be acheivable. At the moment though I want to run about 15psi max till I get it setup properly.

Cheers

from what i can see they look like a good idea as it will allow it to leak a required amount of boost, but off boost the gate/ball will stop the system drawing in air and upseting the running but might be wrong

Lee Reynolds

After taking it off and cleaning it all out, refitted it and I seem to be getting somewhere now! Better adjustment

cossie82yb

Mine was the same,at first boost spiked high up and i couldnt get the right pressure but when i got it apart and cleaned it from inside all was well..
Works nicely now on my cosworth,boost comes hard because of the ball valve.

Nice piece of kit!

Mine was always mint!

Bleed valve....made in sydney where they run no boost..... LOL
