Coyote gets its own 80mm electronic throttle body, the last step before Ford would move to a dual-bore design. Computer studies showed a minimal 3 horsepower gain with a 90mm twin bore, which wasn't deemed worth the cost or packaging headaches. Details such as the edge shape of the throttle blade, recessed screws, and partially cutaway shaft are all there to support either the Coyote's low 650-rpm idle speed or voracious appetite for air at 7,000 rpm. With no idle-air bypass, the team says controlling such a large throttle body is a calibration challenge.
