[DML] Clutch pedal pressures

[tobyp@xxxxxxxxxxxx]

Hello List - We received an inquiry from somebody regarding the 
appropriate amount of force that should be necessary to push in the 
DeLorean clutch pedal.  Anyone who has driven a long parade in a 
DeLorean knows that the effort is fairly high as compared to 
a "modern" car.  Well, in order to give this person a definitive 
answer, I actually measured my pedal.  Using some highly specialized 
equipment (bungee cord, 4X4 block of wood, and a digital bathroom 
scale) I have the following results for Winged1.  This car has a 
several years old Centerforce clutch setup (with the counterweights, 
although the car wasn't running during this experiment), reasonably 
fresh master and slave cylinder, stainless steel braided line, 
adjustable pedal linkage, and uses Valvoline Synthetic DOT 4 fluid.  
The initial push was about 12 - 15 pounds, and ramped up to 27 - 28 
pounds when the clutch diaphragm started to release.  These values 
were fairly consistent over a half-dozen tries (without pushing the 
pedal all the way to the floor).  Does anybody else have any data 
that they would like to share on this topic?
