So once I'm in manual mode, what would I do push the gear selector into neutral to rev up the engine ?
If I do this, wouldn't it take me out from the sport mode ? I don't understand. Will you please explain.
Thanks.

- valve float happens when the valve spring isn't strong enough to force the valves closed at higher rpms. The fix in the HP world has been to install stiffer valve springs but that increases wear and friction.
The reality is the engines in our cars won't float the valves until after redline but it makes a logical sounding reason. I think the same thing would be accomplished by setting the rev limiter at any rpm below redline but there is no harm in it being lower.......and it probably stops some owners from needlessly sitting in neutral and revving the engine to redline just to hear the noise! ;-)
