A friend  and I are having a discussion re the use of a 110HP pressure plate
in a  140HP motor. The goal is to further reduce rotational inertia (already
have  a bolted flywheel with no inertia ring). I seem to recall that there
are  some torsional issues with the 140 that are damped out by the bob
weights  in the 140 pressure plate. Memory fails me on this (it's the second
thing  to go <G>).
Anyone care to comment pro or  con?

Thanks

I doubt it. I think it was just extra mass to allow the low-end-torque  
impaired 140 and (especially) the Turbo to actually start off from the stop  light 
without killing the motor and/or stumbling. The 140/180 pressure plate is,  
supposedly, cast of nodular iron, better material. Several people  (racers) have 
machined off those nodes, returning the mass to that of the  110, but with 
the better material specs. 
Remember the racer's motto "If some is good, more is better, and too  much is 
just right!"
 
In this case, "If less is good, much less is better, and too little is just  
right!" As we see racers stumbling off the line with lightened flywheels, etc.
