Has anyone replaced the bypass valve that comes with the Vortech kit with another bypass/blowoff valve?

Results? Comments?

 

not sure but i thing the greddy type s will fit?

 

I tried the Greddy Type - S! It fits, but didn't like the release sound (i.e. sequential flutter), so went went back to the Vortech BOV.

 

I also tried Greddy type -S I went back to Vortechs as well. Still have the Greddy S in the box! Don't know what to do with it?

 

Has anyone changed over to the Greddy/HKS and had problems? It is my understanding that the Vortech has more of a bypass valve which more or less acts like a closed loop.

With a BOV, the air is vented to atmosphere. Will the MAF misread information causing problems (hesitation? running rich?)

Are the Vortech and Greddy interchangeable?

 

The Greddy S type and RS type are BOV's and not Bypass valves . Work different . I couldnt get the either Greddy's to work . The Bypass valve on the Vortech was designed to vent when not in boost and close when vacuum drops and PSI starts to build . The vacuum closes the valve and the boost helps it stay close till the TB closes . Then vacuum builds and it open back up to vent off the boost built up in front of the TB . The BOV works in the other way . Its closed under vacuum and vents when boost builds to adjusted level . So when the TB closes the boost builds in front of it and opens the BOV only long enough to vent the boost at the adjusted level

 

Rob at Z Car Garage in San Jose, CA did mine.

He's got some sort of silencer he created and it works great. Super quiet.

Hit them up for details.

He did mine also, I can hardly hear it now.

 

I am not looking to silence the sound of the Bypass/BOV. I'm acutally trying to get a louder sound (the typical BOV 'voosh' sound) which is not evident with the Vortech one.

 

try the forge diverter valve ( 007)

If you want it louder simply turn the bypass valve so the opening is pointing out to the side instead of towrd the middle. You'll be happy and it's easy to do. That's how I have mine and everybody can hear it.

 

got any pics of this?
