bleeders work by allowing some of the boost pressure to be vented, rather than going to the wastegate. To reduce the boost, you need to lessen the amount of air being bled off.

If there are no markings on your bleeder, such as a + and - symbol to indicate which way to turn it, you can try turning the bleeder 1/2 a turn clockwise. Take the car for a drive and see which way the boost is going, then adjust apropriately.

If you do have markings, just try adjusting down by 1/2 a turn at a time, test drive, then adjust again as necessary.

May I ask why you only want to run 6psi? thats pretty low, below stock on an R32 or 33.

Another way you could get the boost down is to remove the bleeder competely, so the boost goes directly to the wastegate. This way you will just run whatever the minimum boost of the gate is.

at the moment my car is running very rich, and i dont have enough money to get it dyno and tune yet :) so i was advise 2 run very low boost. The bleed value has + and - but i cant turn it for some reason, it has 2 screws and i took them out but still i couldnt move it

The screw you need to turn is on top of the valve, not the ones on the side that hold it together. In my turbosmart valve the screw is inside a blue metal ring on top.

I think its clockwise to reduce boost, you tighten it to reduce the amount of air it lets out.

The lowest boost you can get is stock because thats controlled by the wastegate spring instead, so just turn the valve all the way clockwise until its closed.

Ummmm wouldn't turning boost down increase the richness problem ?? Turning the boost up would create more flow, more air, leaning out your richness.

But I wouldn't advise you to just turn your boost up - You really need a tuner with Dyno & Wideband Lamda probe thingy to tune it safely.

How do you know it is running rich ??

Do you have a factory ECU ?

What sort of car you got ?? I thought factory boost on a GTS-t is 7 PSI , so I don't think you will get it below that....

hey,

car is 93 gts-t

stock ecu, i know it is running rich as i can smell the fuel, also i get flames out of my exhuast (i have a cat)

car is running aftermarket turbo (unsure wat it is maybe highflow, hks ssq bov, hks super drager exhuast, airfilter_cai)

Is the BOV plumb back or atmospheric venting? If you are running stock ECU and non plumb back BOV then that is the reason for your flames. AFM sees the airflow of the pssshhht and fuels to suit. Result, rich mixture, fuel smell and flames.

Not that there's anything wrong with that... :devfu:

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
