LSA at a Glance

Narrower LSA:

• Moves torque to lower rpm
• Increases maximum torque
• Narrow powerband
• Increase chance of engine knock
• Increase cranking compression
• Idle vacuum and quality is reduced
• Valve overlap increases
• Decreases piston-to-valve clearance

Wider LSA:

• Raise torque to higher rpm
• Reduces maximum torque
• Broadens powerband
• Decrease chance of engine knock
• Decrease cranking compression
• Idle vacuum and quality is improved
• Valve overlap decreases
• Increases piston-to-valve clearance
