The Allmond Marine Stage 2 is an evolution of the 16HR00004 cam used in the 525 EFI
The intake event (solid line) is optimized for improved dynamics while keeping the valve events the same. Higher max lift and 1.5° of asymmetry for improved volumetric efficiency with modern cylinder heads
LSA of 115.5° gives equivalent valve events (EVO, EVC, IVC, etc.) to the 16HR00004 cam’s 114° LSA
Adv. Duration | Duration @ 0.050″ | Duration @ 0.200″ | Valve Lift @ 1.74:1 | Lobe Sep. Angle | |
Intake | 298 | 237 | 158 | 0.640 | 115.5 |
Exhaust | 304 | 244 | 162 | 0.632 |
