Nissan 370Z Touring: Brakes and Blips and Revs, Oh My!

Another theory, in agreement with Chris: What if it is just that the flywheel is relatively heavy in mass, and its inertia brings the engine revs up a bit once the tranny load is removed by clutching in? That sounds feasible.

The flywheel mass will never make the motor spin *faster* - it will only maintain revs. Think of spinning a plate - no matter how hard you push it, it won't accelerate (faster, for those pedants among you) when your hand stops touching it.

However, I do think the friction point on this clutch is encouraging us to put the clutch in slightly before letting off the throttle in order to maintain smooth declutching of the gear. That extra throttle time is raising the revs. At least that feels right in my case. I think the lightweight flywheel is going to do wonders...

Hey imag, you're right, guess I wasn't thinking things through.
