We focus on 2 areas of engine balance.
The first is matching the amount of power released by combustion in each cylinder. A dominant factor here is the flow through the cylinder head. Our gas flowed cylinder heads flow identically across the cylinders. Compression ratio of cylinders and camshaft wear is also a major factor here. Matched fuel injectors/carbs also dictate balanced power across the engine. These factors together with inlet and exhaust manifold design ensures that combustion between cylinders is correctly matched.
The second area of balance is mechanical. Here, we look closely at the major moving parts of the engine (flywheel, piston and rings, con rods, pins and crankshaft). The piston rod assemblies are blue printed and mass balanced. We also employ race quality heavy duty or coated bearings to match the predicted loads. However, with the crankshaft we have a number of options.
