lighter flywheel

[Acuta73]

The reason for my questions is:

A heavier flywheel acts a bit like a gyro and maintains your RPM between shifts. RPM gain is faster, but so is fall-off. When pulling a load (trailer or just a bunch of crap in the bed) you may have issues down-shifting a grade because your RPM fall-off may be too fast to maintain a gear range. Theoretically it could leave you pulling a hill in first gear because you can't hit second fast enough to not bog the engine into a stall. If you have ever driven a crash-box tranny, you could manually keep your RPM up, but I'm betting this would play hell on your brass.

Good info, Camoit. Didn't ever think of it from that perspective.
