Matt.... Clutch Question..

[Macroni]

What is the difference between Single and Dual Mass?

Thanks.

[Matt Monson]

A dual mass flywheel is designed to dampen NVH better, at the cost of weight. A single mass flywheel is designed to allow for quicker revving and shifting by reducing the rotating mass.

[Macroni]

Thanks Matt

What is NVH?

[Mocker]

noise, vibration and harshness

[Mocker]

They dampen the drivetrain, typically using springs sandwiched inside the flywheel. As Matt says, they are heavy MFers.

Harmonics.

Thanks for the education.

[Matt Monson]

Anytime.

From a performance standpoint it’s free horsepower. It’s mass the engine doesn’t have to din. In my experience it also makes it easier to blip for a double clutch rev match downshift.

[Mocker]

Hah. I always heard/read the H was for harshness. Education, indeed.

[Matt Monson]

All good.
