What is the benefit of a lightened flywheel?

The lighter the flywheel, as soon as you hit the clutch, the faster the engine speed will drop. This is a double-edged sword. Not only does it let you shift faster, you must shift faster – and more precisely.

Is a lightened flywheel worth it?

With a lightweight flywheel, right away you will notice the engine revs more quickly. But for racing, where you’re nearly always operating at the top of the rpm range in upper gears, the lighter, the better. For momentum cars that don’t make a lot of horsepower, single-disc setups work fine with a lightweight flywheel.

Does a lighter flywheel make a difference?

Installing a lightweight flywheel doesn’t decrease torque, but it does decrease inertia, meaning more torque will be needed to break traction with a clutch-kick (drifting or burning out), or to accelerate a vehicle off the line during a launch (drag racing, daily driving).

Is a heavier or lighter flywheel better?

When it comes to choosing the flywheel weight, it is recommended that heavier flywheels are better as compared to lighter ones. Higher the flywheel weight the smoother the operation.

Are there any real benefits from lightened flywheel?

There is a bhp increase from lightened internals and flywheel etc., but it is only during acceleration of engine rpms. Maximum hp is not affected at all. However, to accelerate a mass requires power. Half that mass and half the power is required to accelerate it.

What are the advantages of a lower flywheel mass?

The main advantage to a lower flywheel mass on race cars is that the reduced mass allows the engine to rev more freely. The overall weight loss to the car is really not the key thing, it’s letting the engine vary RPM really quickly. Being able to change RPM quickly can mean faster shifts, getting to a power band more quickly, etc, etc.

Do you need a light weight flywheel for your car?

So should you buy a lightweight flywheel for your car? The advantages of a light weight flywheel are the same as reducing the weight of any part of your drive train, you are going to get a quicker revving engine. This is fantastic once you are moving, because it means you will get to the higher RPMs, where the power is, much quicker.

Which is better a heavier flywheel or a lighter flywheel?

The lighter the flywheel the faster engine revs will rise and fall but you will lose momentum on a hill more quickly. Whereas the momentum in the engine is maintained with a heavy flywheel the momentum is reduced and the hill has a much more direct effect on the engine output.
