If you scale down a 3.6 l engine linearly to 1/3 size, would you not get about 133cc (3600/(3^3)) ?


Bonzi --

Excellent! You get your revenge for my catching your omission of the divide by two step in the 500G acceleration thread!

However, you don't get off with a total victory here. The displacement would actually be more on the order of 300 cc (I don't have time to do the math right at the moment) rather than 133 cc, because a linear reduction of dimensions by a factor of three would reduce displacement by a factor of 3^2, not 3^3.

This is because the displacement varies by the square of the bore, but varies linearly by the stroke.

Good catch, though.
