Hi Philip, That 1/3 scale is really something! But did you drop a zero? You wrote "100 cc flat-12: 24 valves," 100cc is about 6.1 cu. in. divided by 12 and one cylinder is 0.5 cu. 1n. Not impossible, but if the original was a 3000cc, 1000cc sounds a lot more reasonable. TokioOkie -- In the video the builder describes it as a 100 cc flat-12, so I simply quoted him without thinking. English is not his first language and he may have meant 1000 c.c.'s. Thanks for the heads-up. Philip

Response from:

accually you are wrong here with two respect's, the scale model is 103 cc not 1,000cc and Pierre Scatti is french not italian, the reason it is 103cc not 1000cc is because it is the dementions that are decreasing, not the volume, so the hight, width and length all are scaled to 3, that makes the vomume scaled by 27, do you see how it works? so 103 cc is resiable, it is not exactly to scale but it is very close

i would like to point out that you have made two mistakes, firstly Pierre Scatti is french, not italian, and secadly that the displacment of the engine is 103 cc, not 1,000cc, i will explain how this works, as you might have been confuzed, the displacment of space is scaled by dimentions, not volume, so if the hight, width, and length meserments are all scaled by 3 that would mean each measerment devides the displacement by 3, 1/3 the hight, the length and the width, your accually deviding the displacment by 27, not by 3, 3x3=9 9x3=27, the scale of the engine is not perfect, it is accually off by about 8cc but it is close enough, the important thing has not changed though which is the power to wait ratio
(sorry for my bad english)
