Hi Ron ,
My car will have an alternator. I would like to use the stock Bugeye tach. I
was thinking of driving the tach directly from a jack shaft attached to an
appropriately sized pulley. Say 1/3rd the diameter of the main crank
pulley. This way I would not need a gear box. Or do I have this backwards ,
i.e. the tach has to turn 3 times as fast as the crank ? I haven't spent any
time on the problem yet. I will be very interested in what you come up with
.
