Hello
It's been well documented that the benefits of coil on plug over a distributor is that there are no moving parts to wear out and no spark plug WIRES. Many also claim a "hotter" spark via more dwell time on the coil. Same goes (almost) for wasted spark.
Are there any documented examples of where switching to coil on plug results in more power/torque?
At what power level is this necessary?
Is there any reason to go coil on plug if you are in the sub-300hp category, and not seeing above 7k on a daily basis?
Someone give me some convincing evidence!

No spark plugs? As far as I know, the only engines that don't have spark plugs are diesels...and they have glow plugs to start when cold...

woops! I meant no spark plug WIRES (edited since)Brad-Man wrote:No spark plugs? As far as I know, the only engines that don't have spark plugs are diesels...and they have glow plugs to start when cold...
But at any rate, the real thing I'm trying to get at is what are the tangible, real world results? High dwell times and all sounds great in text, but what does this translate to on the buttometer/dynometer?
