Think this is what my problem is

I had a Dawes fitted, and lost the original pipes, so I ordered some from the dealer, and picked them up today (expensive !!!)
(one pipe, one T-Piece, and one right angled pipe, 22 quid, the right angle pipe was 13 quid)

Anyway I digress,

I took the Dawes off, and put the new pipes on, and been out for a run, anyway im hitting 9 PSI max

But just looking through the parts again, I forgot to order the part called 'Orifice' which turns out to be the restrictor

Would this be the cause of low boost (combined with the Hot Weather)

Cheers

Steve

 

yeah, no restrictor will allow the boost to reach the actuator sooner and so opening it, limiting boost.
The RA i had boosted to about 13psi max (std) hot or cold weather, no differance, so its prob lack of restrictor.
Ed to say that my RA was non sti and 96my, probebly the same std boost as your motor.

Yeah, with complete removal it'll kill the held boost level as well as the spool. Don't forget the standard size restrictor for most cars is 1.2mm. Without it the bore of the t-piece pipe goes up to over 3mm!

 

Thanks guys, as I expected

Ah well back to the Dawes, till I either find my original pipes, or order this 'Orifice' from the dealers

Steve

 

Why have you taken the dawes off ?

 

Scoobynet Paranoia / Hot weather / ECU has no control over the boost

I wanted to see how my car was really behaving in the humid weather

 

Sonic, the, erm, orifices, are pretty easy to make from a brass woodscrew, piece of brass bar, whatever's handy. You should be able to get small drills fit for the purpose from a local tool supplier or model store.

 

Same problem on mine.....waiting for the part from subaru

 

k9any where have you ordered yours from?

 

I got David from jap -innov to order it for me, i think he has orderd it from the local subaru dealer, its not a part they keep in stock so its going to take around a week.

I tried one off another car but the hole was too restrictive was getting 1.2bar on full boost!....1.0-1.1 should be right.

 

u changed the 2 tiny pipes for sum red ones while i was at vboa billing last weekend

drove home and the thing was hitting 0.6 bar boost
found one of the pipes and refitted it and the boost went back up, couldnt find the other one lol

 

which pipe has the restrictor in it, Thanks.

 

the one from the Turbo to the T-Piece

 

OK, I confused now. Mine has a tee piece with the restrictor in and the pipe goes to the top of the boost soliniod, the other pipe goes to the boost gauge and the third pipe goes to the inlet manifold. the pipe from the turbo goes straight to the middle pipe on the boost soliniod. The bottom pipe on the soliniod goes to the actuator. Is this wrong. Can you tell the correct connects, please?

Thanks

 

mine is like this

Boost Solenoid to T Piece (centre bit)
Actuator to left side of T-Piece
Turbo to right side of T-Piece

the restrcitor should be in the pipe from the right side of the T-piece to the Turbo

Thats how it is on my MY00

 

I had this once after i'd removed my Dawes for something, the car was pants. Turned out that i'd put the pipe with the restrictor in it, back on the wrong way round Wouldn't have thought it possible, but by turning it round, problem solved

Mikey <Dawes back on now by the way and all is well >

 

Dont pay big money for the pipes if you lose them, resrictors and pipe+T-Piece cost me about £2.50 from a small car shop near me.

Steve,

I have a pipe with a P1 restictor (slightly bigger restrictor) in the garage doing nothing. I had it on before I got a tek 2.5. The tek 2.5 alreday does this so I don't need it. Interested ?

Dave.

 

P1 restrictor is smaller and will make a UK car overboost. Usually far worse than yours did Dave.

 

John,

Thanks for that, forgot you had said that

Dave.

 

Thanks anyway, but ive ordered one now from the Dealers, as my car is in for major service & Eibach fitting

Erm Jamesn wish I knew before hand

small pipe - 2.50
T-Piece - 3.00
turbo pipe - 13.72 !!!!!ffs
clips - 95p each

Total come to something like 22 quid, and I didnt get the restrictor

I know what you mean about putting em on back to front, I fitted my Dawes back to front yesterday, Boost went off the scale

 

Can anyone tell me why I do not have a pipe from the boost solenoid to anywhere after the garage fitted my TurboXS boost device?

There is now a pipe under the solenoid with nothing on it.

Cheers Ian.

 

If u didnt get the restrictor sonic then where are you going to get it from?....thought that is what you wanted?

 

Sorry my mistake you got it after!

 

no probs, I still need the restrictor, but my main dealer has ordered it for me, as my car is still in having its service & eibachs fitted, should get it back today

 

Ian236...the TurboXS REPLACES the boost solenoid. Hence not needing any pipes on it. The ECU has no control at all over the boost level when a dawes, turboXS or any other mechanical boost controller is used.

 

any one got a pic of the pipe, your on about and especially the restrictor, as ive fitted a boost controller, and new pipe,s noticed one of the std subaru pipes coming from thr tubo, going into the intercooler, had a section ,where it had been cut, then fitted to a ,sort of, section, to reduce its size, then another pipe coming from it to the, turbo section before the intercooler, is this the restrictor. mark

 

Turbo Steve.

Thanks for the reply - I understand now.

Ian

 

Here you go, a pic of the new subaru hoses & T-piece that cost me 22 quid !!!, new updated parts apparently

Havent got the restrictor yet, but it is a very small piece of brass with a hole in it, im told

 

Still waiting for my restrictor, tried a P1 restrictor on my 97UK, was peaking boost at around 17-18psi....KnockLink and Lambda Link were reading fine.....is it ok to keep the P1 restrictor on?...or can it damage my engine in the long run due to too hogh boost?
