Hey, SuperJ, thhe boost ports, and finger ports idea was considered as a "Crutch" for the old style Echo cylinders, but only gained about 150 rpm for the many hours involved with a grinder and mill to get the work done. .not financially feasible, if you know what I mean.

As for HP numbers. . I doubt you will EVER see me quoting such a thing .. strictly RPM /prop size because that's the only way you can really relate in THIS portion of the hobby ..

Now. . WHAT makes you think that BME has not done their homework on their new cylinders and gotten it RIGHT with the new design??? You sound to me like the same folks who said the Earth was flat, or that a Wheel driven car could never do a quarter mile quicker than 8 seconds. . . THOSE people were Engineers too, remember. . .

Remember. . BME has gotten more out of stock weedy style cylinders in their 102's than most anyone else has. . power per cc considered. With the new jugs. . I really don;t think that even YOUR nephew could do much to improve them, and then it would be to compromise something jsut to get more top-end power. . which is the exact OPPOSITE of what BME is trying to do.

See. . YOU want power numbers. . . . BME wants midrange tractability as well as a pretty good top end .. and as EVERY engineer knows. .. the two ARE mutually exclusive.

You REALLY just do NOT understand the design concepts and overall ideology behind the BME line of engines. . do you???

ANYONE can make top-end power. . . . . THAT part is EASY. . . but you know. . WE don't use Top End power ALL the time. Think about that. .
