The real problem is that you can only get out the same power you can put in with these ignitions regardless of coil size and type, basically whatever your mag rotor and coil can feed into a cdi and coil can not be boosted so a bigger ignition coil wont give a stronger spark unless the voltage andncurrent coming from the mag coil is stronger. A stronger magnet rotor helps as well as antighter gap between the rotor and stator and more windings on the mag coil is where the improvement needs to start at. Some magnets are pretty weak right out of the box and others are really strong, if you got a nice strong magnet rotor you'll have more spark energy. With more spark energy a better coil could be used as well as a wider gap at the plug to take advantage of the increased spark energy.... there is a decent amount of power hidden in the ignition system and when someone comes up with a better mag rotor and coil combo then some of these aftermarket cdi's that use motorcycle or dirtbike coils may be a lot more effective. Selling an aftermarket cdi setup to a customer that has a weak mag rotor will just convince that customer he just got took with another gimmicky part. The other alternative would be to convert to a battery powered coil and better points or cdi type ignition that could offer a hotter and stronger spark to go with the improved timing curves. The timing curves also need to be variable in a wide enough range that can improve a well built engine as well as a stock engine... the only problem here is if the customer don't know what they're doing and set their timing curve too hot for their setup then they'll be convinced that brand x cdi just ruins engines. Or when the timing curve is fixed and not adjustable by the end User, most customers will experience less power depending on how their engine is set up.To bad a company as MSD or Mallory does not come up with a better system.
I,m sure not a sparky guy. I know just enough to get my self in trouble. So I guess
we are stuck with what we get on these engines.
