Cobra Jet Concept: Twin-Turbo 5.0!


Recommended Posts

 

 

I SOOOO almost had a reply finished for your original post... For "future" reference, Warner Bros. :shades:

Gotcha. ;)

 

This article is a bit confusing. If it's ecoboost, is it direct injection? Also, how is it that those tiny turbos are cranking out all that boost?

 

Either way, I REALLY want to see that intake manifold. :D

It's twin turbos but not direct injected so they're not calling it ecoboost.

And if you ever looked at the combustion chamber there is no space for a direct injector.

Part of a new base engine is its longevity. With engine production life-spans often measured in decades it was important the Coyote had long-term breeding. Mike explained it: "We knew that someday there would be a DI version of this engine. We knew someday there would be a supercharged version of the engine. We knew that someday someone would want to do something on it," he explained. "So we wanted to make sure when we did the initial design work that it would be robust enough to not have to re-engineer the whole thing down the road and any subsequent programs would be very investment efficient and time efficient and so we did package DI injectors, we did really improve the bulkhead strength to take supercharging, we upgraded the cylinder head bolts and the main bearing bolts, all of that stuff ... We just wanted to make sure it was a good base going forward, that the architecture would last us the next 10 or 15 years."

Perhaps the final major head-design challenge was packaging everything into the downsized Coyote head. This was only slightly complicated by leaving room for an EcoBoost fuel injector. Its path low on the intake side was protected during Coyote development in case Ford decides to fit the somewhat bulky direct injection injector to the 5.0-liter in the future.
