Just a few thoughts on distributors for modified 907's.
Since most of us simply use parts that Lotus included in various later iterations of the engine, then it would make sense to use a distributor from a later Lotus.
Some of the Esprit guys are using a spring set from Mr. Gasket (#928) to re-curve their 45D distributors. They like the steeper curve which is more like the stock JH. I don't know if this is seat of the pants engineering or was actually developed by a tuner.
The 9xx is not listed on the 123 website or http://www.starchak.ca/ because none of those 16 curves are right for the JH or Esprit.
I have no doubt that Garry Kemp or other knowledgeable tuners can re-curve for more power but the laypersons like me should probably stick with a stock unit.
Remember, you can check the basic curve with a timing light and a hand held tachometer.
Cheers,
Kurt
