CP Forged Piston Set, BMW N63, Pro-Xtreme, Alusil

These pistons are suitable for use in engine blocks with factory alusil bores, no sleeving is required. Recommended piston-to-wall clearance is ~0.0025 - 0.0035 in

5150 AutoSport Pro-Xtreme Forged Pistons by CP-Carrillo for BMW N63 Engines with factory Alusil bores

The 5150 AutoSport Pro-Xtreme Forged Pistons, built by CP-Carrillo, are designed for high-horsepower and high-RPM applications in BMW N63 engines. Engineered with aircraft-grade steel, these pistons are built to withstand extreme forces, ensuring reliability and durability in high-performance builds.

Key Design Feature – Offset Wrist Pin:

These pistons incorporate an offset wrist pin design, where the pin is slightly offset to minimize piston thrust against the cylinder wall during the powerstroke. This innovation reduces friction, leading to quieter operation, improved rod-to-crank angles, and enhanced power efficiency.

Proper installation is critical: the etched arrow on the dome must point toward the major thrust side to maintain optimal performance. (For more information or to learn more, visit our blog post on Wrist Pin Offset and Piston Thrust.)

Performance Capabilities:

The Pro-Xtreme Pistons are specifically engineered to handle up to 2000 HP, making them ideal for turbocharged, drag racing, and street/strip applications. Additionally, they are designed for high-speed operation at up to 9500 RPM, ensuring the engine delivers peak output efficiently and reliably.

Manufacturing Precision:

Each piston is meticulously manufactured using advanced CAD (Computer-Aided Design) and FEA (Finite Element Analysis). These processes guarantee precise fitment, weight distribution, and the durability necessary for forced induction builds and high-rpm operation.

Key Features:

• Designed for BMW N63 engines with superior performance at extreme RPMs.
• Offset wrist pin reduces friction, noise, and optimizes engine efficiency.
• Handles up to 2000 HP, perfect for turbo, drag racing, and street builds.
• Rated for engine speeds up to 9500 RPM to achieve peak performance.
• Constructed from high-strength, aircraft-grade steel for maximum durability.
• CAD and FEA-optimized for precise fit and structural reliability under stress.
• Engineered to meet the extreme demands of high-performance forced induction.

Pro-Xtreme Piston Sets Include:

- Pistons
- PVD Rings (Install Guide Here)
- Pins
- Locks
- Spec Sheet

Please note, the Pro-Xtreme Piston is engineered to handle up to 2000HP, however, the Standard Wrist Pin can only handle 800-850HP. To exceed 850HP, it is a MUST to use Heavy Duty pins.
