The Heart of Performance: Devil Developments Forged Engine
At the core of this formidable upgrade lies a commitment to engineering excellence. Built by the renowned Devil Developments, these engines are constructed using components specifically chosen for their strength, durability, and ability to handle extreme stresses. When you're aiming for outputs exceeding 750bhp, every single component, from the pistons to the oil pump, must be of the highest quality to ensure reliability and longevity. This engine isn't just about raw power; it's about delivering that power consistently and safely.
The meticulous build process ensures that the engine is balanced, blueprinted, and ready for installation, designed to integrate seamlessly into your Focus ST225 or RS Mk2. Pumaspeed's recent delivery of these units means they are fresh builds, ready to be dispatched or fitted. However, with only a limited number in stock, securing one of these bespoke powerplants requires prompt action.
Unpacking the Specifications: What Makes It So Potent?
The ability to handle 750bhp+ is not achieved by chance; it's the result of carefully selected, high-performance components working in harmony. Each part plays a crucial role in managing the immense forces and temperatures generated by such high power outputs. Let's delve into the specifics:
- Mahle Pistons: These are not your standard pistons. Mahle is a world-renowned manufacturer of engine components, and their forged pistons are designed to withstand the higher combustion pressures and temperatures found in high-horsepower applications. They offer superior strength, reduced expansion rates, and excellent thermal stability, crucial for preventing piston failure under extreme boost.
- K1 Rods: Connecting the pistons to the crankshaft, connecting rods are subjected to incredible tensile and compressive forces. K1 Technologies produces high-quality forged steel connecting rods known for their strength and precision. Using K1 rods significantly reduces the risk of rod bending or breaking, a common failure point in highly tuned engines.
- BIG VALVE CONVERSION: This is a critical upgrade for maximising airflow. By fitting larger intake and exhaust valves, the engine can 'breathe' more efficiently, allowing more air-fuel mixture into the cylinders and expelling exhaust gases more effectively. This directly translates to increased power and torque, especially at higher RPMs. It's a fundamental step in achieving high horsepower figures.
- Newman Stage 2 Camshafts: Camshafts dictate the timing and duration of valve lift. Newman Cams are a respected name in performance camshafts, and their Stage 2 profiles are designed to optimise valve overlap and lift for enhanced power delivery, particularly in the mid to upper RPM range, where maximum horsepower is often made. This helps the engine make the most of the increased airflow from the big valve conversion.
- RS Mk2 Ported Cylinder Head: The cylinder head is where air and fuel meet, and gases are expelled. Porting involves meticulously shaping and smoothing the intake and exhaust ports to improve airflow dynamics. An RS Mk2 head, already a robust platform, benefits immensely from professional porting, further optimising gas flow and contributing significantly to the engine's overall efficiency and power potential.
- HP High Capacity Oil Pump: Lubrication is paramount in any engine, but especially so in a high-performance unit. A high-capacity oil pump ensures that sufficient oil pressure and volume are maintained across all engine components, even under extreme conditions. This prevents oil starvation, which can lead to catastrophic engine failure due to excessive friction and heat. It's a vital component for engine longevity when pushing high power.
- King Bearings: Engine bearings support the rotating components like the crankshaft and connecting rods. King Bearings are known for their precision and durability, offering superior wear resistance and consistent oil film thickness, which is essential for reducing friction and ensuring smooth operation under high loads. Reliable bearings are crucial for the long-term health of a high-performance engine.
This comprehensive list of components, combined with Devil Developments' proven build expertise, explains why this engine has a track record of successfully running 700bhp safely and reliably in the past, with the capacity for even more.
