I have not seen anything on fixed sc pulleys here on the forum , anybody have any experience with them ?

ps , i see EC also make fixed pulleys but only for V8s it seems
see here : Article: Eurocharged offering clutchless/fixed M113K V8 (W211 E55 AMG) supercharger pulleys, picture and dyno
This has been discussed before here. CLICK
The SC free wheels all the time and the car sits still with the engine running for a small percentage of time when you think about it, Heat generated at idle would be the least amount normally and easily handled by the cooling system.
I think some people might look back on what they said at the time and have second thoughts about what they said.

These have to be very cheap to make, they say CNC machined as if it was a small wonder but that is what is used these days in machine shops, nothing special. The steel would by my estimate be 1/3 of the cost, profit could be quite high if made in decent size batches. without the clutch and its complications these should only cost $200 or so.
