I don't know what wrong with my blow off valve it start to make a complete diferent sound I could say almost not to much sound I have hks SSQV, what could be wrong?

 

are you noticing any loss of power, or strange idle?

Your diaphram could be failing.

Look into the synapse engineering BOV's if this one is on it's way out (synapse uses solid design, no diaphram to fail)

 

the idle is normal, (Your diaphram could be failing) don't understand what u saying, u mean the blow off valve is done (broke)

 

The diaphram in the blow off valve itself.

Thats why the other guy was asking if your have strange idle issues, because it might be leaking under idle (if the diaphram was broken).

I have the HKS ssqv myself. Make sure the vaccum line isnt pinched. That happened to be before.

I ran a LONG line from the UIM to the HKS bov i cant remember why and i guess the way i routed it, it was pinched a bit and i had no boost. The car felt really slow lol. The hose to the ypipe was also loose too so that might have contributed to that.

I cut it in half and just ran it direct. Now the vacuum line has no turns, its just straight from the UIM to the bov.

 

thanks for the info

so there is no chance that bow off valve is damage?

 

something is wrong only boost 5 I have set up 11 I can't find the problem.......
