My car has a HKS bypass valve on my p-1sc intercooled procharger setup. When i got it the vacuum lines were blocked off. I only have one line hooked up now and it works, but not sure if it's working right. I was wondering if anyone had the same valve and how they have it hooked up, or just some info would be nice. Thanks

 

does yours make any sounds when shifting??? ive never seen anyone run one of those not saying it isnt done just new one to me ...and im curious how it sounds if any at all

 

It has a woosh sound. Best way to describe it is someone pouring water out of a bucket onto the ground. Really sounds like it is moving some air.

 

and its the blowoff valve and letting it dump in the atmosphere or running a hose from it and dumping it back into the intake like a bypass vlave??? ive never heard any bypass valve make a noise i know the hks blow-off valve sounds awesome i didnt know it could be used as a bypass becuase ive never noticed a place to put a hose to run it back to the intake piping

 

Ive got a vortech bypass valve and it doesnt make a sound

 

It blows off into the atmosphere... So it has a woosh sound. Haven't decided whether to reciculate it, leave it, or change it for a blow off valve for the sound. Any suggestions?

 

It's really up to you which way you want to run it, bov or bypass. Neither has a performance advantage unless you are using a draw through setup, where you HAVE to run a bypass to get the car to run properly.
As far as the plugs being blocked off, what do you mean? Do you have a picture of it or can you tell me how many there are?

Edit: I found a pictures of one. I'm guessing this is what you're talking about anyway

If you're talking about the extra vacuum line fitting on the bottom left, leave it open.

 

Yeah... That's what i'm talking about... What is it for?.. I'm all about understanding how something works instead of just knowing that it does...

 

It's a vent
