Here's your problem.

"[6] Now construct an Engine #2: P(rpm) is still maxxed out at P1 @ R1, but is higher than Engine #1's before R1. Especially at R1e, Engine #2 makes more power".

Did you just mentione "but is higher than Engine #1's before R1. Especially at R1e, Engine #2 makes more power"? Well, it's still a matter of HP in the end, isn't it? Because at this point, your lucky engine has more HP than the other. And you have to try to make this advantage overal out-weight any other advantages, if any, the engine 1 allowed to have.

Remember my initial statement: 终极高手知道hp，半罐水知道torque.因为hp是torque和rpm的产物。如果有人知道torque和rpm curve,他不只不觉中已经在谈论hp了。It's the HP amount gets transfered matters. All the arguements we had essentially made you to rest on the HP; whether peak HP　ｏｒ　ｎｏｔ，　ｗｈａｔ　ｙｏｕ　ｈａｖｅ　ｂｅｅｎ　ｔｒｙｉｎｇ　ｔｏ　ｄｏ　ｉｓ　ｔｒｙｉｎｇ　ｔｏ　ｍａｋｅ　ｔｈｅ　ｏｔｈｅｒ　ｅｎｇｉｎｅ　ｈａｓ　ａｃｕｔａｌｌｙ　ｌｅｓｓ　ＨＰ to use。ｒｅｍｅｍｂｅｒ　Ｉ even had the HP　ｂｏｌｄ　ｆｏｒ　ｙｏｕ in one of my prvious thread？　Did you really believe I fell for the 20 rpm trick?
