Yeah lucky indeed. If i remember correctly, he said that the flywheel makes the revs go up and down much faster but there's a slight loss in torque. The pulleys, on the other hand, improves the revving speed a bit but also increases low to mid range torque. So having both is a good idea actually. They complement each other in my opinion.

the lack of resistance may be perceived as a drop in torque but as far as i know, a flywheel shouldn't directly affect affect power or torque figures

Could be. I'm not really sure but the heavier flywheel is good for carrying momentum which might be what he's feeling.

Yea i think so, when you put your foot down the car should respond just as well, its when you take your foot off or have very partial throttle that it may feel a bit torqueless due to the inertia factor you mentioned.

I didnt notice a drop in torque with a 4.7kg flywheel - the engine just felt more dynamic and wanting to rev

Yep that could be it.
