Engine blocks have changed, so have cylinder honing practices

Total-Seal-HoningStoryHere’s how to apply new procedures and gain power

By Alfie Bilk, September 2014:

In the past two decades the metallurgy in engine blocks has changed—and not by a small amount.

Cylinders are now much harder and with modern honing practices they accommodate rings that are much thinner, lighter, and lower in tension—often with exotic coatings.

In addition lubricating oils have been modified significantly to reduce friction and viscosity. All of this has contributed to new power generated by the engine block, but to take advantage of it, new honing procedures have to be adopted. The techniques employed for the past twenty years are rapidly becoming unsustainable.
