I was relocating my 3 port boost selenoid and was wondering if i would encounter any known problems the way that i had mounted it ?(upside down)

please see pic

 

The orientation shouldn't be a problem. Biggest issue I can see there is that I can't see the third port - and that given where the bracket is, there doesn't seem to be any room for it. Take it you're running in two port mode?

 

according to this diagramm port 1 is unused

 

Yeah, just like A'PEXi's 3-porter - 3rd port is open and just vents to air when BDC-ing...

 

What have you done with the spare port? Is it open or blocked? And what about the t-piece and restrictor, have you disconnected them or are they still there in some way?

 

port 1 is opened and is unused as it vent to atmoshere,t peice and restrictor are not present as far as i know.

 

anyone else shed some light? will the 3 port being upside down affect performance?

 

No shouldn't make any difference at all.

 

Being upside down wont affect it Jim. The only thing to check is that as its being run in the 2 port config the restrictor pill still needs to be in place. At least thats the way the perrin 3port has to be.

 

As above seems it is being run as a 3-port with the outlet vented. If it was me I'd plumb back into the inlet tract as per OE, but provided the old return has been blocked, the very small amounts of air vented out of the system won't affect the operation of the car.
