I just had the flywheel changed on my 74 2.0L 914. Mechanic said the old flywheel was a "lightened" one and my new one is stock. I'm curious about you all's opinions on the difference; pros and cons of each. Apparently the PO decided to go for more high end acceleration than low end? I've never seen anything about this on the forum.

Good info here on the pros/cons of each.
Fuel economy - A heavier flywheel will increase MPG on the hwy since it's easier on the engine at cruise (flywheels literally store power/torque) A lightened flywheel simply frees-up HP to go to the rear wheels that would otherwise go to spinning the extra weight of the flywheel. Thus the motor feels more powerful on acceleration. |
