One other thing; I’ve never understood this idea of engaging 200 RPM before peak torque. You want maximum power to the rear wheels right now, the moment you hit the gas. There’s absolutely no reason to wait for it while you gain speed. I can recall several corners, (long sweeping turns) where the RPM stays right at an RPM, many times at clutch engagement, and if you’re 200 RPM below peak, you’re going to be slower. It probably is more important with 2 cycles, they drop fast below peak torque, but I’m sure the rule still stands with 4 cycles.
In LTO racing I’m thinking it’s less important because the only time, in most cases, you’re slipping the clutch is on starts and restarts, but even there, it’s important. Seems to me you would want maximum HP right at the start, no need to wait for maximum HP at the rear wheels while you get up to speed.
