I just though of something, I was reading on another forum (C&D) with a member saying that the rotaries are hand built and may result in compression differences in the vehicles.

And basically, there are a great difference in mileage of the cars. Also, from dyno tests, there are discrepencies.

So I was wondering, if the compression, hp, and gas mileage are anyway related to each other. Maybe higher hp cars have higher compression but worse mileage? And vice versa. Any ideas?

 

I think it would be more accurate to call it hand-assembled machined components vice "hand built". I doubt seriously if this method of assembly would significantly affect any of those things. Assuming, of course, that no human errors were made during the assembly process.
