Mazda’s Eunos Cosmo (1990) and FD RX-7 (1992) followed suit, but for many, the car that popularised the tech was the 2JZ-GTE-powered MK4 Toyota Supra. Porsche’s 959 was the first production car to utilise sequential turbos in 1986.
Then at high engine speeds, all of the exhaust gases are routed to the larger turbine to deliver high boost. As revs rise, a bleed of exhaust gases are directed to the larger turbo to pre-spool it. Sequential turbocharging activates a small turbocharger at low RPM, reducing turbo lag. The Maserati Biturbo of 1981 might have been the first production car to use a pair of blowers, but it simply fitted one to each bank of cylinders of its V6 engine, known as parallel turbocharging. Controlling the boost pressure this way also made a wastegate unnecessary.Ī different method of tackling the same issue was simply to use two turbochargers a small one and then a big one. Honda realised that with an actuator, it could alter the angle of the vanes offering quick spool up and then at higher engine speeds, increase the AR.
Decreasing the AR, with a smaller turbine with more acutely angled vanes will decrease spool up time, but reduce top end performance. Increasing the AR by using a large open-vaned turbine will increase spool up time, but increase top end performance by allowing more air to flow. Honda already realised that turbo lag was largely a function of the turbo’s aspect ratio (AR) the relationship between the area of the exhaust turbine inlet to the radius of the turbine blades itself. MORE What is a turbo and how does it work? Also required is a wastegate, to bleed off excess boost. Hotter air is less dense and therefore less effective at making fuel burn, so in order to help cool the air that’s been squeezed into the induction system by the compressor, it passes over a heat exchanger, or intercooler, that removes the extra heat and channels it elsewhere. Bingo! More power.Īnyone who has ever tried pumping up a road bike’s tyres using a handheld pump will appreciate that as you compress a gas, you heat it up. With more air in, you can throw in correspondingly more fuel. This fan is mounted in the car’s air intake so, as it spins faster and faster, it sucks more air into the vehicle’s cylinders. As the engine blows hot gas past the fan blades, they spin up, in turn rotating the shaft and the other fan, called the compressor. One of these fans, the turbine, sits in the stream of exhaust gases exiting the cylinders. Two fans sit at either end of a metal shaft so that both spin around in unison. Owners of these high mile juggernauts recommend oil changes every 6-7k miles to keep the engine running smoothly.Reduced to its simplest form, a turbocharger isn’t hard to understand. Some owners have reportedly reached 300, 000 miles with their EcoBoost. Even when you use the recommended oils and service your vehicle regularly, you won’t make up for abuse if suffered on a daily basis. Major modifications like bigger tires, suspension lifts, heavy accessories, and large bumpers all decrease engine longevity since it needs to work a lot harder to lug the extra weight around even when empty. Modifications include upgrades like exhaust upgrades, intakes, and mild engine tune-ups without compromising the reliability or longevity of these engines. The EcoBoost is built tough and is designed to last a long time. A factory standard 3.5 EcoBoost engine can give you up to 250 000 miles (402 000 km), and more if the vehicle has been well taken care of with regularly scheduled maintenance and no major alterations. Drivers can most probably get above the 250,000 even if the owners have made light modifications without any long term reliability side effects.

WHAT IS TURBO BOOST CUT DRIVERS
This engine provides drivers with the power they expect from their Ford trucks and also produces fewer ozone-damaging emissions. It was a 6-cylinder that could act like an 8-cylinder while using a lot less fuel. One of the most appealing aspects of Ford’s EcoBoost engine is the low fuel consumption.
It is an advanced engine design that offers plenty of grit to pull a load and runs smoothly along the highway. The F-150 is known to be the best-selling truck in the United States and most of the F-150 trims have the EcoBoost engine, which is one of the reasons both new and used models sell quickly.ĮcoBoost was a big engineering and technological leap for Ford. A year and a half later it was added to the F-150. Ford put it under the hood of the Ford Flex, Lincoln MKS, and MKT. Ford originally introduced what drivers know as the 3.5L EcoBoost engine as the TwinForce V6 engine in 2009.

EcoBoost is a series of direct-injection, turbocharged gasoline engines produced by Ford.
