This rule applies from the smallest relay coil up the the CERN SuperCollider.
( The above is a gross oversimplification, but I think you get the gist )
Bottom line : You ain't gonna make the OEM SC clutch grab any harder by increasing volts or amps, it's doing all it can do with 14v and whatever amps it is drawing without blowing the fuse.
You would need what was called back in the good old slot car racing days, a 'rewind'.
Has anyone look to see if the clutch on the V8's are any stronger ?
I wouldn't be so quick to desmiss this concept - but maybe wait to hear some more feedback on magnet faces - maybe a separate thread/summary.
Nothing lost in having the discussion of boosting the magnet power.
Looking at the isentropic chart for the SC indicates you are probably at twice the original design SC power = twice the forces - but I'm sure the magnet had headroom to start with.
As with a smaller pulley and more boost being "within" the production design envelope of the car, the coil and amps may have capacity to be boosted. EG: Ignition coil boosters used on the 2.3L SLK230's pumping in 16V to the coil packs instead of 13.2-13.5V (
that/s what my Woody cigarette lighter readout reads most of the time). I've used these voltage boosters also for my cooling pump to increase V=speed=flow.
Might be a consideration here if at all needed.
