==Effects of changing lobe separation angle== The lobe separation angle (LSA) is ground into the cam at the time of manufacture and cannot be changed by the installer. ===Widen (larger) LSA=== *Raises torque to higher RPM *Reduces maximum torque *Broadens power band *Reduces maximum cylinder pressure *Decrease chance of engine knock *Decrease cranking compression *Decrease effective compression *Idle vacuum is increased *Idle Quality improves *Overlap decreases *Natural EGR effect is reduced *Increases piston-to-valve clearance ===Tighten (smaller) LSA=== *Moves torque to lower RPM *Increases maximum torque *Narrow power band *Builds higher cylinder pressure *Increase chance of engine knock *Increase cranking compression *Increase effective compression *Idle vacuum is reduced *Idle quality suffers *Overlap increases *Natural EGR effect increases *Decreases piston-to-valve clearance
