A 4.6-liter V8 powerhead is naturally aspirated and features deep-breathing double overhead cam/four-valve architecture with a short-runner intake manifold mated to a cold-air induction system.
An 11:1 compression ratio boosts torque output while the 7000 RPM redline extends the power curve. A dynamic oil pickup system is designed to maintain critical engine oil pressure under high-G loads.
A cut-down flywheel, deleted balance shaft and carbon fiber top cowl optimize weight. A competition engine calibration is optimized to take full advantage of 360 APX powerhead tuning. While bred for racing, this four-stroke powerhead is also designed to deliver unmatched durability and reduced maintenance in a competition environment.
A digital control offers smooth and precise throttle application. The 24-volt starter produces instant dockside starting in competition. Above-water exhaust offers unrestricted flow and produces an exciting tone for racing fans.
