I know the the difference between the two but what i was thinking is the why is it the on a, for instance the greddy the boost is pushing against the piston where the, say hyperboost DV, the piston is facing towards the intake side. i know my hyperboost works fine the way it is but this is jusy one of those rants i decided to post and see what all of you had to say.......

Depends on the strength of the spring or the adjustability as to whether it will work with the piston facing the Boost....
