so i was driving around the other day and finally got my boostsciences rdv valve working and rather enjoy the sneeze you get. but out of curiousity and basic ignorance lol i was wondering if inserting an hks fin into either hose or inside of bpv would do anything. i believe the hks fins are 1 inch ID, correct me if im wrong... and would i be stupid doing this lol. just for sh*ts and giggles?
