PREPARATION MOTEUR : MODIFICATION RAPPORT DE COMPRESSION

Let's delve deeper into 4-stroke engine tuning. We've already covered compression ratio, volumetric ratio, and engine compression ratio, which are all essentially the same thing. In this new episode on 4-stroke tuning, we'll explore modifying the compression ratio by installing high-compression pistons with a more pronounced dome, reducing the combustion chamber volume in the cylinder head, lowering the block height, thinning the head gasket, and lengthening the connecting rods.
