With regards to this thread: https://www.scoobynet.com/technical-...-solenoid.html

Is it the actual Solenoid (metal pipe bit I clean) or just the hoses?

Will WD40 be ok for it?

 

Both if you want.
Not sure.

 

Mate,

unclip all the rubber vacuum pipes from the solenoid.

Use brake/clutch cleaner (it evaporates, wd40 leave a residue)

Spray through all the metal pipes until it runs clear as it will remove any sludgy build up

 

Cheers guys, better to be safe than sorry.

 

Make sure you dont forget what pipe came of where!

 

Whilst you got it off why don't you do the boost mod and drill out the solinoid I think I used a 3mm dia drill this will increase spool up and should give you 2-3psi more boost!

One of the best mods I made as it was free and what a difference it made!

The standard boost solinoid is very restrictive!

 

What exactly do you do? does that work on the 2 port boost solenoid i have on v3 sti??

 

Yes mate it will work but only drill the one going to the actuator!!

 

oh ok so you just drill down the little pipe into the solenoid? do you have to be careful how far?

 

is that not the same as adding a bleed valve?

In which case the bleed valve would be better to control??

 

what if his car is already mapped for X amount of boost then he goes and does this, its not a good thing surely?

 

will this work on a v10 wrx?

 

They never made any v10's, they are all 4 pots

It will work on all boost solenoids afaik (and please, dont refer to your car as a version, just give the model year, there are too many different market cars out there and they are all different, hence why subaru dropped the versions after the STI version 6 cars).

Hey Tony, see that hook over there? See the coat that's on it? That's yours, that is.

Quite. Not to mention that the imaginary "version numbers" some people round here still use are... fictional, and open to intepretation.

 

Thanks ive had my car remapped will i have to have it done again if i do this mod?

 

how deep do you drill into the solenoid?

 

hi m8 ive got a 93wrx which is over boosting. i fitted another module(second hand) which sorted it but after a while it happened again. i was told this can happen if there,s too much oil in engine. aparently the oil goes into the boost control module. is this true and will this cleaning procedure help me?
