The 'Not So Dark Art' Of Engine Balancing | Engine Building Basics 02/04

In this performance engine building lesson you will learn what engine balancing is and where to remove material from when balancing your pistons and or connecting rods (con rods).

You will also learn what a harmonic damper is and why you want one along with how you can minimise the amount of material you need to remove from your rotating assembly when you match your heaviest components with your lightest before you start, making the task a lot easier as an added bonus.

Note sometimes the task of balancing your engine is referred to as engine blueprinting. This is not strictly correct, as blueprinting is when you are working to weights set in advance, not just balancing to even things out in general. As discussed, harmonic balancing is also entirely different and a common area for confusion.
