this is for some who dont know what the difference is

 

BOV's are really just sound... Oh yeah and some can recirc.

 

mine is a recirculating but i was wondering, are recirc better than atmospheric or what

 

How can you say something that prevent surging on your compressor just for sound?


Compressor surge is bad news for turbo bearing...

 

I currently have the Greddy Type RS and would like to get the HKS SSQV but HATE the bird chirping sound! But I like the way the HKS functions, via the two seperate valves.

 

how do you know when your compressor surges or not

 

it happens when the boost pressure in the pipe doesnt get released, since the engine is slowing down the pressure inside tries to get out any way possible (going back thru the turbo compressor) putting stress on the bearings. it doesnt always happen to lower boost cars but it does put extra wear on the turbo. you can really see it on higher boost cars such as supra's, evos, skylines.
its like a shuttering noise.

 

it's a fluttering sound like the one from my HKS BOV. stupid thing dont work right. Bought the 2007 revision to hopefully fix it. if not, I'm going custom BOV duck mod FTW!!!
