BLOW OFF VALVE

[HOBADNESS]

DID ANYONE CHANGE THE BLOW OFF VALVE ON A 03-04 9-3 VECTOR-AERO?CAN YOU CHANGE IT??

[SS]

Lol, relax man! No i dont think anyone changed the blow off valve on their cars here, and i think it is possible but i am not sure if something is out for it yet!!

Not possible to install the BOV in a T8 managed engine. Need to recirculate the air.

[Cayman1]

Well just buy a recirculating BOV and not one that vents to the atmosphere.

[Liquid Calm]

Don't think you can do a BOV, at least not a direct replacement of the stock one in a SS. I have looked and the bypass valve is on the outlet of the turbo.
I guess you could do a custom job and just unhook the stock valve. Put in an aftermarket BOV on the i/c piping. Don't think it would be worth it though as it still would have to recerc the air. If it is the Psss sound you are after fordge has a 1/2 recerc and 1/2 vent to atmos, it may work in a custom fitting. :-??

[Cayman1]

When you say "bypass valve" do you mean wastegate?

I have never seen a blow off valve as a part of the turbo and i didn't think it was possible.

Wow,

I guess there is a first time for everything.

Thanks for the info!

Our 93ss don't have BOV but the Diverter Valve.
However, I seen this guy installed HKS BOV before on this site..
So, Nothing's impossible. :P

:P :P For my new buddy in Hawaii. :wink:

There is a way to convert the stock valve to atmosphere dump 8) I have not had time to test it but have a prototype part on hand. A far more elegant solution. :wink: The ports from the central hole connect to atmosphere to allow dump and therefore make the really cool sound.

Yes..it is intended for make a sound..PSST PSST.. :wink:
Basically, those are used to relieve some of hot circulating wastes go out to the atmosphere..to reduce hot air pressures from turbine and engine recirculates back to the engine.

yea im with you sjhudon, it sounds like from this post there is no improvement to performance with any other these parts just more turbo whistle. Is this correct? Sorry for my ignorance this is my first turbo. im use to working on my mustang not turbos.

[Cayman1]

It also sometimes reduces turbo lag.

well thats a plus. im not sure i want to waste my time and money on a sometimes though. someone let us know how it works.

[sjhudon]

Yea let me know if this has any kind of performance effect, because right now (and no offense to anyone who has done this) but it sounds like doing a mod for the sake of doing a mod. please correct me if i'm wrong.
