Is it better to have a heavy or light flywheel?

The heavy flywheel helps RPM recovery, allows the engine not to lug during the gear transmission. The light flywheels decrease the inertia, so it gives a quick response to acceleration and deceleration.

What are the cons of a lightweight flywheel?

Cons of Lightweight Flywheels

• Reduced Off-the-Line Performance. If you want to maximize performance from a standing start, a lightweight flywheel might not move you in the right direction.
• Rough Engine Feel. With a lightweight flywheel, the engine will feel rougher while running.
• Gear Rattle.

Does a lighter flywheel improve fuel economy?

A lighter flywheel will not necessarily increase MPG as it will cause the engine to re-time itself to compensate and if the fly wheel is too light it may not be able to compensate resulting is lower MPG as well as a other problems.

Can a flywheel be too light?

if the flywheel is too light, it will spin too fast and make your RPMs jump too fast.. therefore, you will not be able to be in the powerband long enough… therefore you need a balance between too light and stock.

What happens if your flywheel is too light?

Does flywheel increase power?

Flywheels, light or heavy, do not increase or decrease power — they impact the engine’s rate of unloaded acceleration, which can subsequently impact throttle response & acceleration through the gears. It doesn’t. Lightened (reduced inertia) flywheels are used to allow the engine to accelerate more rapidly.

What is the effect of a lighter flywheel on performance?

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.

What are the drawbacks of a lighter wheel?

Drawbacks – it takes effort to get the wheel rotating and stops the engines revs increasing or slowing down quickly. A lighter wheel takes strain off the engine and allows the engine to rev more freely, as a bonus as there is less weight the engine is able to release more power.

Should you buy a lightweight flywheel for your car?

Thus the more torque it will be able to apply when the clutch is engaged, without increasing RPMs. 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.

What happens if you reduce the weight of the flywheel?

If you reduce the weight in the flywheel it will reduce the work the engine has to do allowing it to rev more freely. We all know that weight is a destroyer of performance so a lighter flywheel also makes the car lighter but treat this as a small plus it’s not the main reason for fitting one.
