Probably the most overlooked machining process when it comes to making really good power, particularly NA, is cylinder honing. Whilst you might think it’s as simple as a super cheap hone on a drill we can assure you it is an extremely important process to get right for your particular application.
Today we start with hardness testing the block, look at the fuel type, oil type, choose the correct ring material for that hardness & application, then work out a cylinder wall profile to suit. To do this properly we need the right equipment to be able to measure the cylinder wall to validate that honing process.
This article below gives an overview of what goes into good cylinder wall prep.

Cylinder honing is a far more complex topic — and process — than you might think. There are many variables to be considered throughout the process.
