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.

From my Corvair days... I used aluminum flywheels..
Heavy flywheel tends to smooth out idle and make starting from a dead stop easier. More rotating mass.... let off the gas and the revs drop slower and smoother. Depending on how much less the lightened flywheel weighs... Engine will accelerate faster.. BUT, at the same time... Letting off the gas is like stepping on the brakes. They do take some getting used to. You can go too far and make the car unpleasant to drive in regular traffic. Personally, i really liked the way the car felt with one. I think some early 911 2 liter flywheels had holes drilled in them to make them lighter |
