HI Kelvin - I am a little puzzled by this statement.... "This will be fact until someone can prove differently to me".....I would urge you to speak with data, and not an opinion.

on that note, is there any chance you could get both coil types and do some independent testing?......as a gesture of goodwill if you provide both new and old coil types, I will provide the engine and dyno facility (essex based) and I will pay for all dyno testing while you are present.

I design high-performance electrical hybrid motors for a day-job, both permanent magnet and switched-reluctance, and have been doing so for the past 8 years with major OEM's in the automotive hybrid industry, generally been designing high performance engines for 20 years.

I work with all manner of steel lamination suppliers and processing techniques, plus all manner of copper wire winding techniques........if there are 2 coil suppliers present at Honda, its highly probable they are sourcing their lamination steel from different suppliers, and they are using a different copper winding technique, with a different copper fill ratio......lots of potential differences there - mucky

Just a small process change in the steel will result is a different electro-magnetic behavior, which could easily be causing both a stronger spark, and it could alter the ignition timing, this is where the extra 0.1hp could be coming from.

Considering the latter point I would urge the dyno testing to be done with a strobe light.

Quite frankly I would not trust a word that Honda have told you, they are talking in terms of a generator engine with huge build tolerances, you are talking about a race engine which is up against many hard limits, I will be highly doubtful that the folk you are talking to at Honda have even any basic knowledge of electro-magnetics, and the parameters that affect its performance......electromagnetics are a minefield to the untrained eye, the attention to detail required is essentially how I make my living.
