I have an opportunity to install an aluminum flywheel on a new 1400 motor, this is in a car that sees (spirited) driving on the road and some track time. Heck to get anywhere in a 1300 you need a lota peddle.
Is the lightweight flywheel, 10 lb with ring gear too light? Just how does the skinny flywheel effect driving in a two seater?

thanks

The only problems with a light weight flywheel are in street driving, whenever you have to start out it is going to require more throttle effort to get the car moving. With the loss of the inertia in the flywheel the motor is going to want to stall easier. The plus side is the motor will rev up quicker and spin down quicker. I have had a 9 pound flywheel in my Ti (1600) for many years and have not had any problems, the only time you will regret it is starting out on a steep hill otherwise it is very easy to get used to. Kinda like cams with no power below 3500 pain in the *** in stop and go but real nice out on the road.
