Barry, Club Enya is another that contains good usefull info, as to the others, it's hard to embellish numbers etc because too many others have the same engines. It's laughable when terms like, spank, mighty and others are used to describe an engine that lots of people own. I'm very careful about that and when I use the peak number I say so and when I use 50 rpm under the peak I say so, 50 under is the most useful because it is steady, absolute peak many times is unstable and the rpm wanders up and down a little. One could post the average at peak and post a greater number but what purpose would that serve.
