I just realized there's a 3.917 gear available from Tomei as well, and the 4.08 is actually 4.083 (not that it matters rounded to mph below): Redline speeds in gears

I just realized there's a 3.917 gear available from Tomei as well, and the 4.08 is actually 4.083 (not that it matters rounded to mph below):

Redline speeds in gears 2-5:
3.357: 52, 82, 118, 167 (current)
3.692: 47, 74, 107, 152
3.917: 44, 70, 101, 143
4.083: 43, 67, 97, 137

I think I may have to do some more analysis, since the gaps between the trans gear ratios aren't linear, either. Maybe somehow graph this all out into a map of overlapping gear powerbands. Then I could figure out, essentially, my ideal shift points (probably all at redline, but it doesn't hurt to check), and then figure out whether the widening gear gaps in the higher gears means I'm losing effective power by pushing some of my "normal" speeds out into that range, and whether the torque gains from the gearing offset that or not at various speeds. Then maybe I could also pull in some notion of average speeds from my track data to find out which ranges are more important as well, if it comes to that.
