Wondering what may be the optimal 016 Getrag for my CAV mono. Rear tires are 295/50/15 with a rolling diamter of approx. 26.6 inches. With the currently installed AAZ she's turning about 3,150 on the freeway at 75mpg - exactly what Ron E's spreadsheet predicts (nice work Ron!).
I have a 5N and an AFC. The AFC has similar gearing in 1-4 as my current AAZ however the 5th gear ratio is much taller (.73) providing about 2,700 rpm at 75mph - about where I'd like it. The 5N gearing is slightly shorter in 1-2, about the same in 3-4 and taller in 5th though not as dramatically taller than the AFC.
For a price, I also have access to a 3U however this box seems too tall with a .64 fifth (that's 207mph at 6,500rpm). My car should max out at around 155 with the 302 SBF crate engine currently in her so gearing to 200+ seems silly.
Anyone have any experience with the AFC v. 5N v. 3U?
I realize some have used the 5N with a different r&P but want to leave that off the table here for discussion purposes for the moment.
Thanks!
