the supercharger does run all the time because it is driven by the belt that drives your alternator, no its not noisy, no more so than normal and yes the power is awesome, is it worth the money? i think so.
and to reply to Fat White VR6's valid points, the brakes on the vr6 are good as standard, if you aren't altering the vehicle weight or braking later into tight bends why upgrade the brakes? it is reccomended that the front engine mount is changed to a vibra-tech mount cos the standard one is a bit soft, as for suspension, i would say that is a matter of personal choice, i dont try to drive my car any faster around bends because its supercharged, if you put your vr6 round a corner at 60mph so will i, then i will nail you out of the corner.
if you see what i mean
