Crankfire vs. Distributor????, anyone have hard numbers???? Options

[Mueller]

Does anyone have dyno numbers or know where to point me to for a comparison between the two different types of ignition??

Knowing that I can turn my regular distributor into a fully electronic programmable electronic ignition (okay, it'll still have the rotor which must distribute the spark) I was wondering what the crankfire has over the distributor ignition besides 0 moving parts that can wear out.

for the distributor the path for the spark still needs to go from the coil>rotor>cap>sparkplug wire>sparkplug....

the crankfire is coil>sparkplug wire>sparkplug

what effect does the rotor and cap have on ignition if everything is the same (advance curve and coil rating)????

A crank trigger is the only way to go if you have the option. I doesn't have the problems that a dizzy has, worn out parts, limited accuracy, etc. A crank trigger can more accurately measure crankshaft position, will not wear out. I doubt you will see a measurable difference in a crank trigger and a good quality dizzy (Mallory, MSD, etc). What you will find though is the ability of the supporting systems to make more power. Typically crank triggered systems are some sort of computer controlled unit. This allows individual cylinder timing and fuel optimization, that is where you will find more HP and torque.

Crank triggered coil on plug ignition is about a close to optimal as us mere mortals can get. Be nice when Megasquirt figures out how to do timing without using the dizzy.
