In a lot of racing, folks are real big on the weight of their flywheels because it effects how the engine accelerates. But on a lot of occasions I’ve seen folks go with the lightest flywheel and clutch setup possible only to find that the car in undrivable or at least more difficult than it needs to be. I see this a lot on the autocross, and it is usually folks who could get a lot quicker on the course by improving their driving a lot easier than changing parts. But does a light vs heavy flywheel actually change the horsepower that an engine is making?
Richard is about to test that, using a lightweight flex plate and a heavier flywheel on the engine dyno.
