Since r.p.m. is a large part of the horsepower equation does Konrad's horsepower to weight comparison also follow the same scale when you compare thrust to weight ratio of a 2-stroke vs. 4-stroke? Is AAC a much more expensive process than say ABC?


I have to admit that the weight idea has been rolling around in my head since I started a post that had people commenting about the low weight of their older loop ported .60's etc. I then thought if the same engines had been produced without the brass or steel liners they would really be light.
