So what's a tranny good for if you can do 12,000 RPM? I did a simulation of a ferrari 458 vs an M4, vs 3 818s. The first 818 has a subie tranny with a 3.90 final ratio and shifts at 10,000 RPM, the second has a 2:1 reducer instead of the subie tranny and a miata 3.6:1 rear end. The last one has the subie tranny but shifts at 6,000 RPM. Shifting is simulated at 80ms, like the M4 tranny. My car will probably weigh around 1100kg so that's the number I used. What's interesting is that the fixed gear 818 doing 0-100kph is slower than the ferrari but faster than the M4, but is just as fast as the ferrari at getting to around 120kph and just as fast as the M4 at getting to 160kph. In other words it's geared for the the autobahn. So what tranny should I go with? Here it is:
