Myth Buster!!........

It is a common perception that a large flywheel is used to increase the torque of and engine and with a light flywheel an engine will have less torque but this is NOT the case! Heavy flywheels are used only to ease the smooth engagement of the clutch so Grandma can take off without stalling the engine and that's it! maybe improve idle quality a little also. Once the car is rolling and the clutch is fully engaged the flywheel becomes completely unnecessary because the entire vehicle and its drive line becomes the flywheel storing huge amounts of momentum. Any additional weight particularly on the crank shaft only reduces the vehicles ability to accelerate briskly. So if Grandma isnt going to drive your car and you don't mind having to use a little more finesse with the clutch pedal then you will enjoy all the benefits of having a snappy responsive engine with much improved acceleration that comes with installing a light flywheel. Even if its only a daily driven road car! We have many happy customers driving around on these flywheels just find and ask someone and they will be happy to report that drivability is not compromised at all, but the improved response and acceleration is very pronounced!
