“Enabled by new crankshaft and rod bearings, as well as a viscous crank damper, this Coyote revs 500 rpm higher than the Gen 2 to 7,500 rpm. As such, it needs a rev-friendly intake. Engineers didn’t just grab something off the shelf; they engineered a new intake manifold with specific runner tuning designed to increase peak power speed. It uses Charge Motion Control Valves like the Gen 2 intake to promote better low-end horsepower without sacrificing that top-end speed.”
Very good read about the differences in the engines.
