Has anyone ever experimented with increasing the diameter of the transaxle clutch cable pulley?
Obviously the housing would have to be modified that much goes without saying.
My wondering on this idea would be to shorten the "throw" at the pedal with the hope of increasing shift speed (I've converted to a cable shift).
Direct experience with this modification very much sought.

The clutch cable pulley doesn't do anything except change the direction of the cable pull. The rate at which the clutch is released or applied is controlled by the clutch pedal, not the pulley.

If you modify the clutch pedal, you'd need to make sure you still had enough throw to fully release the clutch, but still keep the throw short enough to not over-travel the pressure plate fingers.

I'm willing to bet you're not going to find many people with experience modifying the clutch cable system, since there isn't really any advantage in changing it. Usually, the only change people make is to just replace the cable with a hydraulic system.
