Supercharger compressor clutch Anyone have a compressor clutch on their supercharger? Similar to fan clutch or AC compressor clutch, etc. This would make it possible to engage it based on % throttle, engine speed, etc.
A bypass valve would also accomplish what I'm looking for.
Just curious if anyone has looked into this and what they found.

An A/C clutch will fail quickly as they were not meant to handle that kind of load.
It sounds like a fun idea, but it will fail in practice.
I would save the time and energy and go with a proven conventional supercharged or turbo setup.

Using a bypass valve to recirculate the pressure does the same with very simple parts
At low load all the boost is vented back to the SC inlet so the blower freewheels. This lowers the drive cost to about that of an idler pulley

A TVS essentially does all that for you. No load from the s/c under vacuum conditions and boost instantly available once you mash the go pedal. My TVS2300 will go form cruise vacuum to full boost in an instant at anything over 2500rpm. Hell, it will go from cruise to full boost under 2500rpm, but it's just a little tough on the motor

. If I remember correctly, mercedes benz had a clutch type SC in the 90's or at least one experimental type. I think it had reliability issues or they built a better mouse trap. Personally, looking like Mad Max would be bad azz IMO! An electromagnet operating on a higher voltage like 60 vdc might be able to handle the load but that might cause interference with other electronic components.

I've seen ac compressors lock up on the highway and burn the belt off the motor.
The clutch has the ***** to burn up a 6 rib belt it will carry the blower.
Now engaging the clutch and taking the blower from a stand still mite give the gear box
in the blower a hard time.
If you engage the clutch with the motor not running and started the motor
that would be ok but if your looking to hit the blower "mad max" style
on the run that's a different story.

i seen something about a year ago, I think ATI was working on it , the crank damper/blower pully had a 2 or 3 to one step up ratio, where it would multiply blower rpm vs engine rpm so lets say at normal 3,000 engine rpm the blower is spinning at 20,000 rpm, you adjust the pully to 2 to one , now at 3,000 engine rpm the blower is at full rpm 40,000 and pretty much full boost, so say your engines power range is 6,000 rpm , the pully system will go back to normal 1 to 1 ratio, and still increase boost till max rpm or blower speed lets say 60,000 rpm,, might be a little hard to understand but i think u will get it .
