Not always a difference in the desired direction, though... Not at all saying that you didn't experience an improvement at the tracks you got to. Only saying that "gears" don't always give people what they really wanted, which was a legitimately faster car for their usage.

Opposite is often true. If you add torque to add power, subtract weight, and add lateral grip, optimal gearing will be *taller*. However if you take a given displacement and tweak it more for higher-rpm performance, optimal gearing is shorter (numerically higher).

See above.

The FR-S or the Type R? In either case, you should consider two things:
1. with the same cam profiles, same valve sizes, same intake/exhaust ports, you're not going to make any more power by revving higher
2. simply going to new springs and retainers does NOTHING to beef up the bottom end, which may well already near its limit for reliability at the existing redline/rev-limiter

We used to just call it "LOWER" gearing, but somewhere along the line (late 90s?) newbs couldn't grasp the concept that 4.77 gearing is LOWER than 4.10 gearing.

Calling lower (numerically higher) gearing "quicker" can be false advertising!


Yup. Adding power via adding torque means optimal gearing becomes taller (numerically lower!).

All this talk about math and gear ratios are making my pants a little tight. I have absolutely no idea WTF you guys are trying to accomplish with those formulas tho. Do you guys have some reference material a geek might be able to dip into?
