Okay, i'm presently replacing my Vortech BV with an HKS Racing Bypass Valve.

Anyone know what the proper way to adjust and set a bypass valve?

The Vortech was already preset when I installed it, so i never had to adjust it.

Any help appreciated!

Thanks

 

The screw at the top of the BPV. I would keep it at 5-6 threads.

 

Can you expand in more detail how you would go about adjusting it and obtaining a setpoint?

For example, something like, "adjust screw until the valve closes when at 75% throttle etc..."

I'm guessing this setting is the pressure differential setpoint between manifold and pre-MAF (post compressor) which opens the valve.

Thanks

 

you can watch your vacuum gauge and make sure its closing as you approach 0in Hg.

Realistically I wouldnt touch it though and just mount it as is.

 

Thanks. I'll give that a shot and see how it runs initally.

 

post up some sound clips when you have it installed! i've wondered how the HKS would sound versus the stock vortech bpv.
