Basically, there are several potential limiting factors, but the only ones that you can't really work around are heat and friction becoming excessive for the materials used. | |

Just to feed the engine as RPM goes up means either the velocity of the air from intake to exhaust increases for a constant sized path. And I think the velocity is free just because the RPM goes up. At least to a point. Or, the diameter of the path would have to increase to allow more air and fuel at a lower velocity. I know from nothing about which would be better for either street or racing applications. | |
