a bypass valve on a supercharger is nothing like a bov the bypass valve opens and closes the intake on the supercharger so that the car is not building boost at closed throttle, it opens and closes a dome. so that at closed and part throttle you car acts as though it is na. what it does is it gets sucked open boom you have boost.
a blow off valve is the exact opposite it keeps the motor from boost surge when the throttle is closed and the turbo is at a high rpm. so when you shift the throttle closes and the turbo is still spooling it sucks it open and the noise you hear is the air being spent from the turbo.
i don't know about kraftworks but on my jackson kit (old style roots blower not the new style centrifical) on the b16 i had, the bypass valve was a plate in between my manifold and the roots, so there would be no way to mount it because the valve was sandwiched.
vortec blowers for b-series has a blowoff valve on it but that is because it is centrifical which is really close to being turbo but instead of being exhaust driven it is belt driven. check into them, i don't know if they do k-series motors.
