That's more than horses per liter or, more specifically 1. In an age where one horsepower per cube is still noteworthy, the EcoBoost's pressurized performance is unquestionably admirable, but its torque is the truly impressive trait. The EcoBoost's peak lb-ft is achieved by only 2, rpm, whereas Ford's 5.
You have to look at the monster Power Stroke diesel for an engine in Ford's truck lineup that makes its peak torque at a lower engine speed: Even more important than the low engine speed at which the EcoBoost torque peak is achieved is the fact that it holds it over a broad rpm range. Ford says 90 percent is sustained from 1, rpm to 5, rpm.
That's pretty consistent with the general performance of most turbocharged engines. One of the biggest reasons the EcoBoost achieves its maximum torque so low in the rpm range is its use of a pair of comparatively small Garrett Honeywell GT15 water-cooled turbochargers rather than a single, larger turbo.
Smaller turbos generally "spool"—get up to boost-producing speed—quicker than larger turbos, which helps the engine make more power faster. The Honeywells can spin up torpm.
It's generally true that a larger turbocharger will make more maximum boost and consequently more horsepower in the engine, but because the spool time may be longer, that extra power — and torque — will come higher in the rpm band.
That's fine for, say, a lightweight drag racer that doesn't need maximum torque at the starting line, but for a heavy, production pickup truck that needs low-rpm grunt, a larger single turbo with a longer spool time wouldn't achieve the down-low torque output like a pair of smaller turbos.
The EcoBoost makes boost almost immediately off idle, giving the F a strong feeling of acceleration. It's a textbook example of bigger not always being better.LIVING ROOM 4. Hej! Living rooms, sofas, sofa beds, armchairs, coffee tables, storage furniture, TV solutions.
