The "phsssh" sound generated by the blowoff valve applies to to turbochargers. A Kompressor is a supercharger. Does your dad wish to supercharge his car, or install the AMG Kompressor motor? If he goes with the AMG motor, and wants to hear some thunder, then install a straight pipe exhaust...that thing will roar.

I never heard of a supercharged car using a blowoff valve. The supercharger compresses air by means of the pully (robbing a little power from the motor but making it back tenfold...hence the "whine"). Don't really know where they could install one (blowoff valve) on the sc. Unless...it would be a centrifugal supercharger. Turbo runs off exhaust gases and spools up, and the blowoff valve releases any excess boost. But the sc works completely opposite, not requiring time to spool up and giving istant power. Interesting to follow up on...do you have a link depicting one installed?

www.maxima.org has a section in the forum for S/C & T/C cars. The Stillen Supercharger kit actually comes with a standard BOV but most people replace it with an aftermarket one:
Here is a thread with the included parts:

Here is a thread with some pics:

But if you search I'm sure you will find 50 or so different SC cars with BOV, it's not uncommon.

all 230k's have blow-off valves. they're also called pop-off valves, and are on the intake path before the intercooler. even if it's run by the pulley, it can still build up excess boost, especially when hitting the gas and letting off immediately. it's the same way the turbo works in terms of relieving pressure. the exhaust slows down once the revs drop, as does the pulley speed. pressure can still be there though.

That looks more like a bypass valve, since it goes back to the intake, as opposed to a blow off valve, that goes off directly to the atmosphere. Most stock Vortech installations use the bosch bypass valve, but the bigger bolt on valve can be used for more airflow. If there is no MAF sensor, then a blowoff valve does not hurt anything. If there is a MAF sensor before the compressor, then the blow off valve goofs up MAF signal.
I had two bypass valves on my old 99 SOHC Vortech blown mustang, with air/air intercooler. a 1.5 dia ID bolt on bypass across the intercooler and a bosch bypass across the supercharger. It had 375RWHP on 91 octane, with an automatic and high stall converter.
Most belt driven superchargers use a bypass, for when the throttle plate is suddenly slammed shut when under high boost. The air has to have some place to go.

Prior to my C class, I had a 2003 mitsubishi Evo VIII. The car was equipped from the factory with a cbv (compressor bypass valve). The purpose of a CBV or BOV is to effectively keep the impeller from cavitating with air when the throttle is backed off. Basically the air has no place to go as the throttle is closed and it bogs down the SC/Turbo. The CBV or BOV releases this unused charge to allow to take load off the impeller so it can spool up quickly when needed again. A BOV vents to atmosphere, hence the "cool" noise that people love. Personally I could care less... A CBV vents to the air back into the intake.
Some food for thought. Swapping the CBV for a BOV in the evo caused alot of problems for people with stock electroincs and MAFs. The system anticipates via software an air dump into the intake via the CBV when the throttle is lifted. It richens up the mixture in anticipation of that air being rapidly recompressed from where it was dumped, then back into the turbo. People who didn't suitably change their ecus would foul spark plugs constantly.
