These turbochargers are mounted to high-strength cast-iron low internal volume exhaust manifolds. The engine consumes 25% more air than its naturally aspirated counterparts. On the other side, the transverse 3.5L EcoBoost V6 uses a twin Garrett GT1549L turbocharger which has lesser boost pressure at 11 psi. The 3.5L F-series EcoBoost V6 engine uses twin parallel BorgWarner K03 turbochargers which can spin up to 170,000 RPM and provides up to 15 psi of boost pressure. The fuel pressure reaches 2150 psi, enough pressure for efficient operations of the natural injection system. Further, the intake camshaft has an additional lobe causing a high-pressure pump for the direct injection system. The valvetrain has a polished Direct Acting Mechanical Bucket. The intake valve has a 37 mm diameter, while the exhaust has a 31 mm diameter.Ī single primary chain drives the camshafts integrated with Twin Independent Variable Camshaft. The aluminum cylinder heads of 3.5L EcoBoost have four valves per cylinder, pent-roof combustion chambers, dual overhead camshafts, and centrally located iridium spark plugs at the below-center of the valves are GDI fuel injectors. Undermounted spray oil jets employed inside the block to keep piston temperatures regulated, cool, and strong. The engine is installed with a forged steel crankshaft with six-bolt main bearing caps.ĬNC machined pistons are made from high-strength aluminum with low friction coating on the piston skirt the piston top shape is specifically designed for more efficient combustion. The EcoBoost block is an all-aluminum lineup, an open-deck design with high-strength steel sleeves. Both engines have the same engine block and bore, and stroke dimension. The First Generation 3.5 EcoBoost V6 engine framework was built around the Duratec 35, also known as the Cyclone V6 engine. Valvetrain: DOHC four valves per cylinder.Since EcoBoost 3.5L parallels to power and torque of 5.0L V8s, it is not surprising that this engine would be chosen due to its lower price and leaving the disadvantages out the door for a smaller displaced engine. Through its widespread use among Ford vehicles, the engine would go as one of Ford’s best-seller platforms – the F150 truck. The official production of EcoBoost started in Mid 2009 at Cleveland Engine Plant No.1. The engine reappeared in the MKT concept in 2008 North American International Autoshow on the exact vehicle, but the name was changed to EcoBoost. TwinForce engine’s initial rating is 415 HP and 400 lb-ft of torque on E85 fuel in the MKR model. That also achieves 15% better fuel efficiency and reduced harmful substance to the air. The primary goal of the 3.5L engines is to create a power unit alternative equivalent to the power and torque produced of the larger-displacement V8 engine, such as the V8 Coyote sourced machine. The Ford 3.5 EcoBoost engine was first featured in the 2007 Lincoln MKR concept vehicle badged as TwinForce. But whatever it is, we are glad that machine alternatives are widespread and leads us to more prominent choices. No other truck automaker comes to the reputation that Ford built throughout its developing, innovating, and integrating the truck driving experience into a fun idea.Īs a result, some automakers planned to join and the growth of turbocharged engines brought the best of some engines we have today, mainly due to the competition and overall demand for this kind of engine. V8 engines have been the pretty standard option for those who drive American vehicles for a long time now. The engine released might not be the most docile, in terms of price tag, option for F150 but let’s see what it does The Ford 3.5 EcoBoost started to ring some bells after matching up and rise as more powerful against the naturally aspirated 5.0L V8.
