Torque vs Clamp Load Explained: The Truth About Torque Wrenches in Racing Engines
Are torque specs really telling you the full story?In this EPARTRADE Race Industry Now technical webinar, Shannon Strother (P1 Manufacturing) and Chuck Lynch (AERA – Automotive Engine Rebuilders Association) break down the real relationship between torque input, clamp load, and friction in high-performance racing engines.Most engine builders rely on torque as a measurement, but the reality is far more complex. Up to 90% of applied torque is lost to friction, meaning the actual clamp load can vary significantly depending on lubrication, coatings, and surface conditions.This deep dive…
