BOV
 

may be newb question but i really dont care. but if anyone knows what im talking about then i would gladly appreciate you to help me out. i hear a BOV everyonce ina blue moon that is more of a putter than all the air coming out at once(PSSSSHHH)....anyone know if thats the TYPE of BOV or do you have to fabricate it yourself or what?

Re: BOV
 

thats probably a blitz or hks not sure though, i run a greddy knockoff and it does the psshhhh you are talking about

Re: BOV
 

Could be compressor surge

Re: BOV
 

yea, that sounds more like compressor surge than a BOV

Re: BOV
 

the compressor surge...i wont ask what it is ill do research... :y

Re: BOV
 

it's bad.. very bad.

but one bov that sounds like a flutter is the HKS SSQV bov which i realllllllly want :1 ;D

Re: BOV
 

compressor surge aka compression chatter, is when air being compressed hits the throttle plate goes back and the compressor wheel chops the on comping air, making a fluttering noise, this over time ruines the turbo, thats why bov are important.

and no it aint that bad, just put strain on the turbo that dosent have to be there, supposibly ive heard that in extreme cases the air that rushes back could even undo the bolt holding the comprssor wheel in, i dont know if this is true tho.

Re: BOV
 

YES!!!...you answered my question...thankyou!....ill make sure to get one no matter the cost...nothing sounds better

Re: BOV
 

im not sure that the hks sounds like flutter, ive heard on on a supra and its just a high pitched PSHHT

Boost level can greatly change the sound of a blow off valve
