POINT-3 Optimized Camshaft Profile

• Lift volume was decided after the cylinder head measurement and flow test.
• Duration was decided to be well-balanced with a selected lift volume on the power curve at all range.
• The camshaft profile was optimized to clear points of the valve flow and/or cam lobe friction.

POINT-4 Stock Valve Timing.
