It's not that hard, really.

3rd gear at 3500rpm in the FR-S is 39.5mph (given 1.541:1 3rd gear, 4.10 diff). The same 39.5mph in the AP1 S2000 3rd gear puts it at 3900rpm (4100 in the AP2, which gives it a big advantage here, but we'll keep it to 2.0 vs. 2.0 liter) with the AP1's 1.718:1 3rd gear.

At 3500rpm, FR-S is making 90hp. At 3900rpm, S2000 is making 100hp, 11% more. The S2000 is therefore putting 11% more torque to the wheels at 39.5mph in 3rd gear.

The S2000 obviously kills the FR-S at the top end, especially above 7000 rpm.
Yup.
