How A lot Enhance Does The Ford 3.5L EcoBoost Make, And What PSI Can It Deal with?

The three.5-liter V6 Ford EcoBoost, the founding member of Ford’s EcoBoost engine lineup and one of the dependable turbocharged engines obtainable, hit the streets in 2009. With its particular mix of energy and effectivity, one of many 3.5L EcoBoost’s first assignments was delivering 365 horsepower and an estimated 20 miles per gallon to the 2010 Ford Taurus SHO.

Ford lists the 2024 F-150 3.5L EcoBoost horsepower at 400 and torque at 500 lb-ft. For comparability, the 5.0L Ti-VCT V8 additionally has 400 horsepower however solely 410 lb-ft of torque, and the three.5 makes peak torque at 3,100 rpm versus 4,250 for the 5.0. Nonetheless, the 2024 F-150 Raptor makes use of a Excessive Output 3.5L EcoBoost with 450 horsepower and 510 lb-ft of torque, and the Ford GT Mk II supercar’s 3.5L EcoBoost makes 700 horsepower.

The important thing to the three.5L EcoBoost’s energy is the pressured air induction, or enhance (measured in kilos per sq. inch or psi), supplied by intercooled twin turbochargers. Energy rankings discovered within the early 3.5L EcoBoost come from comparatively minor enhance values of round 12 psi per MotorTrend, and the extra highly effective Ford F-150 Raptor model has a lift of 18 psi.

Aftermarket engine tunes, just like the one from Cobb Tuning, can enhance the horsepower and torque of the inventory Ford 3.5L EcoBoost by boosting stress. For Instance, within the Excessive Output engine within the Ford Raptor, it will probably enhance the stress to 22.5 psi. The second-generation 3.5L EcoBoost, utilized in 2017 and newer Ford F-150s, makes use of twin BorgWarner K03 turbochargers with electronically managed wastegates to handle enhance stress. Enhance is generated by high-tech turbine wheels “comprised of a excessive temperature resistant alloy” able to fast-spooling (as much as 17,000 rpm) shortly, even at low engine rpm. Different 3.5L EcoBoost functions used two Garrett Movement turbochargers.

A Roush Yates Racing Engines’ (RYRE) 3.5L EcoBoost is able to producing over 800 horsepower and unrestricted dyno runs as much as 1,000 horsepower, nonetheless, Worldwide Motor Sports activities Affiliation (IMSA) guidelines restrict output to 600 horsepower. The excellent news, for these desirous to improve enhance stress, is the RYRE 3.5L EcoBoost model that produces 600 horsepower makes use of the identical cylinder bore, crankshaft stroke, engine block, cylinder heads, valve sizes, and valve springs. The Roush Yates engine makes use of twin-60mm compressor, 54mm turbine Honeywell Motorsport (Garrett’s father or mother firm in keeping with MotorTrend) turbochargers with enhance dialed to 10 psi.

One of many quickest and best methods to extend the enhance of a Ford 3.5L EcoBoost engine is by putting in a customized tune from an organization like Cobb Tuning or MPT Efficiency (MPT being brief for Extra Energy Tuning). Along with delivering extra energy by growing enhance stress, a high quality tune can enhance throttle response and transmission shifting.

One other solution to obtain larger enhance stress within the 3.5L EcoBoost is to put in aftermarket turbochargers. Upgraded turbochargers from corporations like KC Turbos, Garrett, and BorgWarner provide “bolt-on” turbo kits that includes each left and proper turbos. Amongst these producers you may simply discover a new-and-improved set of turbochargers designed to suit almost any Ford mannequin powered by the three.5L EcoBoost V6 engine.

One draw back is that the majority of those aftermarket turbos require using 91-93 octane gasoline, and using excessive ethanol fuel blends might require upgrading the inventory gasoline pump system. Some upgraded turbo kits are expressly meant to be used away from public streets.
