i have an hks super seqential bov and i noticed a bit of a difference in performance and it wasnt a good one. it feals like in between shifts it takes the turbo to long to spool up. dose anyone know what im talking about? anyone with same problem? please let me know. i know its not due any leaks. do u think something is wrong with turbo? please help.

 

If you are Venting to Atmosphere that is probally why you are feeling that problem. You need to recirculate the BOV for better repsonse and also to not have any stalling issues.

 

what he said, my suggestion is u want the awsome shoooosh sound, get a Greddy Type RS Bov, its a duel stage so it recirculates and blows off atmospheric, me personally i carry a greddy type s, i get a nice whistle between shifts and my turbo seems to kick in about 300-400 rpm sooner.
