hyperboost diverter valve
just thought i'd share my experience with this little gem....
i was torn between an atmospheric BOV or sticking with a recirculating valve. i took the plunge and went with the hyperboost adjustable valve.
i was surprised on how much larger it was then the bosch valve that came with my procharger kit. it was probably twice, maybe 2 1/2 times larger but not too big. it's adjustable up to 6 mm. i first had it set at half way or 3 mm. i noticed a bit of difference between the bosch and this in that it didn't take that much effort to get boost, meaning i didn't have to push 3/4 down on the throttle to get boost. i finally set it all the way down and again noticed more of a difference. it wasn't like night and day but noticeable enough that i'm glad i spent the $119 for it.
i really like the product. i can here it when i'm driving hard between shifts. i don't know how audible it is from outside of the car.
this is definately an option for diverter valve vehicles. they also have a lifetime warranty on the product so if it brakes or stops working, they fix it for free.
