Grumpy and Cynical
In this month's BMWcar, there was an article about a supercharged M-Coupe. An interested read, but what caught my eye was a statement that the mod'd M-Coupe's lightweight flywheel, which weights about 1 lbs less than stock, may have hurt its rolling acceleration. I don't understand. Why would a lightweight flywheel hurt acceleration times? I would time the opposite would be true. I have also hear that lightweight flywheels would decrease hill climbing power. Why would that be?
