Turbochargers are attached to high strength cast iron low internal volume exhaust manifolds. Ninety percent of its peak torque is between 1,550 and 5,500 rpm. They are smaller, variable-vane, high-pressure turbos allowing peak torque faster (at just 2,500 rpm), and reducing turbo lag. The 3.5 EcoBoost uses twin parallel mounted Borg Warner K03 turbochargers for truck version and Garrett GT15 for other applications. The key component that provides excellent performance is a turbocharger. The pump delivers fuel pressures up to 2150 psi. The intake camshaft from the driver's side has an additional lobe driving a high-pressure fuel pump of the direct fuel injection system. Ford also applied Twin Independent Variable Camshaft Timing (Ti-VCT) on this engine. Camshafts are driven by a single primary chain. The valvetrain has polished solid buckets - Direct-Acting Mechanical Bucket (DAMB). The diameter of intake and exhaust valves is 37 mm (1.456 inches) and 31 mm (1.220 inches). GDI fuel injectors are placed below-center of the intake valves. An oil pan is also aluminum.ģ.5L EcoBoost cylinder heads are aluminum with four valves per cylinder, pent-roof combustion chambers, centrally located spark plugs (iridium spark plugs), and two overhead camshafts. The cylinder block got oil jets spraying oil on the underside of the pistons to keep them cool and strong. High-strength aluminum and CNC machined pistons have low friction coating on the piston skirt and piston top shape specially designed for efficient combustion. The engine is equipped with forged steel I-beam connecting rods and forged steel crankshaft with 6-bolt main bearing caps. The EcoBoost block is all aluminum and an open-deck design with high strength steel sleeves. The 3.5 EcoBoost is built around the Duratec 35 (Ford Cyclone V6 engine) engine block with the same bore and stroke dimensions.
