Menn eru að rugla því saman við að swinghjól geymir orku.
Framleiðir ekkert tog.

Misskilningur frekar.

Mótorinn snýst meira sjálfur eftir að þú ferð af gjöfinni ef þyngra flywheel.

Ég myndi almennt halda að þetta sé alveg kjörið modd í S50Bx eða S54B32 mótora.

Rev-happy en svolítið slugish.. þetta gerir þá snarpari.

Fann flotta skýringu á þessu

Your car will produce the same amount of power that it did before, the difference is the change in rotating mass. Take a bicycle wheel and spin it with your hand and then do the same with a roller skate wheel.

It harder to get the bike wheel spinning quickly in comparison to the roller skate wheel, but it's also harder to stop the bike wheel from spinning vs the roller skate wheel. Translate this to the car and the flywheel spins up faster when it's smaller and the engine seems more responsive. The engine also puts less effort into spinning the smaller flywheel. The drawback to a smaller flywheel however is that it doesn't store the energy that's put into it by the engine as well as a larger one

You will mainly feel this effect going up hills and starting out in 1st gear. Overall, a smaller flywheel does allow the engine to put to the ground what it would normally have to put into turning a larger flywheel faster so it will help you up top



Þá er bara spurningin, passar þetta á 420g?

Þetta er gefið upp fyrir E46M3 og hann er með 420G. Þetta passaði líka í 310Z
