Got a HKS SSQV blow off, and it does not have any kind of adjustment screw on the back. Two places told me that HKS stopped using that adjustent while two other places said that a false company is making counterfit valves that do not have a adjustment. The car is highly tuned and i need to make adjustments on the internal spring, i dont see why HKS would do this.

The SSQV is holding psi under full throttle but under a mild load (about a 13psi pull), the ssqv starts to dump sparaticly. normally i would tightn the spring. what do you think?

 

the new one does not has a set screw

 

The one i got does not have one.

 

you got an old style one, they are both real HKS. Its just that too many people were messing with that screw and causing too many problems that HKS decided to remove that screw. I had both designs.

 

the new ones dont have adjustment screws because people do not know how to adjust them properly

 

+1 on that i was one of the people who didnt know how to adjust it
if you want the one with an adjustment screw i still have mine if you want to buy it.

 

I got one with the screw I dont use it anymore. PM if interested.

 

So i guess im screwed and should have never put it on the car? your cars run poor with bov's as well?
