the main thing i got from all that was the stock ignition system is still not far behind all this technology,with cheaper,simpler components & more reliable,cheaper consumables(ie spark plugs)

the car companies are getting more efficiency out of their engines just thru simple good cylinder head/valve design & engineering,something that doesnt wear out to the extent of a spark plug.

So stock motor=stock ignition + recommended spark plugs

If u want to go playing with your aspiration or cylinder head/valve design then u are throwing yourself into the complex science of igniting whats going on in there with ignition system/spark plug selection,something that is probably quicker & easier to overcome with just plain experience rather than science.

its good to see however,thats theres people like this(with obviously a lot of time on their hands) keeping all those new rubbish technologies honest.
