Changing Boost Help..?

[Kaido_RR]

hey,

I have a bleed value it is blue (no name one it) i was looking at it yesterday and i have no idea how 2 chaneg the boost lvl (i wanna bring it down 2 about 6psi)

can anyone help?

ps. i did a search and was looking for about 30mins and couldnt find anything at all

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

[chaos]

turning it the right way mike

u tried pulling the button out then turning it?

[Trust33]

ive never seen a boost bleed valve before either but do those screws represent your boost adjustment i.e.in for less out for more?/.....no dont wozz there prolly there to keep it together.listen to the others dont listen to me.

[Kaido_RR]

Trust33 took the screws out did nothing. 100% sure they just hold it together

[paulr33]

get a photo of 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)

[Kaido_RR]

also i had alook at it 2day again it has TurboX's on it or something

[51OOO]

same one I have do u have the allan key for it? juts turn the top screw clockwise to turn the boost down,depedning on what car u have u may be unable to run 6psi

[Kaido_RR]

didnt get any allan key thanks 51000 i will go buy one and turn down the boost if i can

[Duncan]

ahh sorry, mine has a flat bladed screw at the top, no allen key required.

But like b-man said, you need to get it sorted out properly too....

[Kaido_RR]

yeah, hoping 2 save just alittle more $$$, so i can get the ecu with in 3weeks or so.

I could pick up an safc II for around $350 or so now but i really dont wanna get one if i plan on buying a ecu in the near future

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:

[Kaido_RR]

hmmm, its a atmospheric venting bov, yes u r right nothing wrong with flames :burnout:

[PTR33]

it sure stops tailgaters :flamer:

And melts your cat !

and bumper, lol
