Day two of the 2023 Engine Performance Expo was even more jam-packed with tech presentations than day one. All this information, just free for the taking.

The Rottler H85AX CNC-controlled vertical honing machine provides an extremely precise cylinder finish.

It also does it automatically, freeing up labor and increasing productivity.

Once machined, cleaning the cylinder walls correctly is a crucial part of proper engine assembly.

Here's Total Seal's process, along with our own.

Modern piston rings require modern honing processes in order to take full advantage of their technology.

Here, Greg Anderson and Lake Speed, Jr go through the what and why of modern honing.

We wanted to see what a ball hone was actually capable of doing to a cylinder wall that was in need of honing.

We availed ourselves of a profilometer and tested before and after, as well as the OEM cylinder finish

Getting piston rings to seal is one of the key components of making horsepower.

Advances in material science have taken piston rings and honing technology to a new level.

Cylinder honing is a far more complex topic — and process — than you might think.

There are many more variables than simply bore diameter and crosshatch angle to consider.
