but i do know everthing else you have said negative about MSD is highly skewed and biased and to say these things about a product that you have no other proof of being a bad product on a board for people that dont know any better is not right and personally i think is bad for your buisiness. i know i tend to shy away from someone that tells me how much another product sucks.
dont get me wrong, i am a VERY big fan of the bosch. if you had valid proof that the bosch was that much better, it would be different. for that matter, no one could even figure out which is more reliable because there are people that have had good luck with both and others have had bad luck with both.
if the bosch was perfect, you would not be repairing any bosch units and bosch CDs having been going bad since they have been putting them in cars. its not like they are just now starting to go bad.

It is my belief that the purpose of the 450 volts vs 300 volts is to more rapidly overcome the inductive reactance of the coil, FAST buildup of coil internal magnetic field, and thereby have a much faster risetime at the plug gap.
Plus I suspect most any plug would have fired long before reaching the peak 45,000 volt output seemingly dictated by the input.
And...
Suppose the plug is fouled with gas or oil or a mixture of same...by the time you get to ignition pulse #8 the probability that the plug has now been "unfouled" would be pretty high, would it not...?
