Piston Wear: Critical Tolerances in High Revs

Technical Bulletin

High-revving engines demand precision. In this technical deep-dive, we examine the critical tolerances that separate a reliable engine from a catastrophic failure.

Topics Covered

• Piston-to-wall clearance specifications
• Ring end gap calculations for boost applications
• Thermal expansion considerations
• Oil film thickness and lubrication dynamics

Case Studies

We examine three engines that failed and three that survived - what made the difference?

This is essential viewing for anyone building a high-performance engine or pushing their daily driver to the limits.
