SE 68MM CNC Porting
Overview:
Unlock the full potential of your Milwaukee-Eight (M8) engine with Ward Performance’s CNC porting service for the SE 68mm Center-Cooled manifold. Specifically designed to fit Harley-Davidson’s new generation center-cooled M8 heads, this porting service guarantees seamless compatibility and maximized performance.
Using advanced 5-axis CNC machining, we meticulously optimize the manifold’s ports to deliver improved airflow, sharper throttle response, and increased power output. This upgrade is perfect for street performance, track builds, or high-displacement engines, and is fully compatible with turbo setups for future flexibility.
What’s Included:
5-Axis CNC Porting: Precision-machined ports for optimized airflow and smoother power delivery.
Performance Gains: Dyno-proven results coming soon.
Turnaround Time: Typically less than one week.
Core Availability: Pre-ported cores may be available if in stock.
Service Options:
Send in my core first - Service my manifold: Ship your 68mm manifold to us, and we’ll port it! (Click here for instructions on sending in your core.)
Purchase Pre-Ported Core: Order a pre-ported manifold (if available).
