Hello, I have a question on a flywheel. I have been racking my brain over this for months, and still no good answer.I i have a 4 wheel drive truck, that is 4,500.lb. 100hp at 4,000.rpm, and 200lb. ft at 2,000.rpm, at the flywheel. The vehical drives at 50mph at 2,500.rpm. with a 1 to 1 final drive ratio. with a loss of 40% thrue the driveline. 31x10.5 tires. What would be a better flywheel? a 10lb or an 30lb. flywheel? on flat ground i could see that the heavier wheel would keep up inerta, but would the lighter wheel be better for going up hills of a constant grade, sutch as a 2mi. hill of 15% grade. if i needed to accelerate up this hill, there would be more power at the wheels/tires, using the lighter flywheel and therefore use less engine power to do the same amount of work, or would there be enough energy in the 30lb. flywheel to help get up the hill. Just an old guy trying to get better performance from an old truck, and trying to figure out some science.:) any help would be wonderfull!
