Secondly, one thing you may not think of with regard to added mass is that it can also come into play in power loss. More massive axles and gears require more energy to get up to speed, adversely affecting rear wheel horsepower. Other factors, like internal friction, play in as well, of course. This friction may be attributable to bearing properties, along with axle fluid viscosity and flow behavior, and can also be influenced by geometric concerns like the diameter of the ring gear (which is intertwined with the properties of how the ring-and-pinion mesh). Though the physics involved may merit a full-blown engineering discussion in a future issue, for now we decided to do before-and-after testing of both of these project cars on TTP's Dynojet for a quick comparison. Our results are:
