It's pretty hard to get a standard for dyno testing the engines. There are just too many things to control. At the end of the day running all the pipes, plugs, head clearances, and fuels will only show you what the best combination is for that location and that weather for that day.

It's great that the manufacturers are finally running their motors on a dyno that gives reasonable results. I can think of several engines that advertised over 1.5 Hp that aren't even close.

At the end of the day, these engines aren't computer controlled and they won't repeat the same numbers day after day. All we can do is look at the powerband and go from there. Sometimes area under the curve is more important than peak numbers.

I'm very interested in the relatively low head temps in the run that was posted.
