20 years ago I wouldn't have thought twice about it. I was like Gumby.

His derivations and justification for equivalent mass are legitimate. I vaguely remember touching on it in college but never used it. Nikitopo's estimate of 16 Kg equivalent mass in first gear feels reasonable but I'm grumpy about being sucked into verifying his assertion on my own. When I get around to presenting my argument logically, the results will be similar. Then I will close by reminding the reader that first gear is used only to leave the paddock and, once on the track, even second gear is a rare event. Meanwhile, for a daily-driven occasional track toy, these changes are silly. Any gains achieved by shaving equivalent mass are all lost from a single missed shift or an early apex. A lightweight, underdriving crankshaft pulley, even for a dedicated track machine, is just plain stupid. Maybe it makes sense for autocross but I bet it would bump the car up to the money-is-no-object class. So even there it's stupid.

I still think that expressing the question as a percentage change in energy expended to accelerate the whole car through first gear is good enough for me. Then, if it's down in the 1 or 2 percent area, I say negligible.

He goes into more detail on inertia calcs than I do, but they need more measurements than anyone really wants to take to be accurate. |
