The sounds are so sweet though, it "ain't" ricing if you have the power to go with it. 
If i'm not mistaken the type s has 2 vacuum ports on the rear of the bov. One on top of the hat and one below it. If you leave the underside capped it should hold significantly more pressure at the cost of part throttle response. There was a mod we used to do on factory 1g dsm bov's that would allow them to retain the factory quick release feature up to a certain psi then cut off the underside port with a 3 port mac solenoid to allow for higher holding capacity. Unfortunately the company that made the part 20 years ago isn't around anymore. But below is a link an explanation of how/why you would mod the factory bov and a diagram of how you would run the Mac valveI’m going to be kicking myself if I have a boost leak after switching out the tried and true TiAL BOV that I’ve had for 14 years. All for the type S sound haha
running factory coils and alternator for reliabilityAre you running a factory ignition system with just better plugs or have you upgraded other pieces too?
