Default It's a trade off

saltshaker Jon it's a trade off about physics. It's about stored energy and about the trade off of how fast you want the engine to spin up up. I stared with a 40 lb flywheel which is great for burnout and cruising a slow speeds. For racing you want the lightest and smallest setup you can get. You know that the rotating assembly,"flywheel, crank, rods, pistons, rings, spacer, and crank dampener ALL need to be together for the correct balancing of the motor. I am now running a 22 lb flywheel. The motor respond quicker with have less weight to spin up. It's ALL about APPLICATION of what you are going to do with the car. You can run an aluminum flywheel on the street without any problems. There is a metal ring attached either with rivets or bolts that can make it rebuildable. It's about matching up, the motor max output, weight of the car, and driviablity you are looking for. Most BB cobra run 11" or 11.5" stock or 1 step above stock clutches. They will last for years under normal driving and even a little showing off. After this you are looking at more expensive single purpose setups. Road racers use multi 6-8" disc clutches for racing. For big HP and torque on the street and have a lite clutch pedal you may want to look at a Street twim disc setup from Mcleod. What trans and motor are you looking to run?? What bellhousing are you looking at. There is alot more to this that just weight of the flywheel. Hope this helps a little. Rick L.
