On the left is something you never want to experience but probably will if your Coyote is subject to high (but rev-limited) rpm and relentless boost from a supercharger. It's the thoroughly destroyed oil-pump gearset from Evolution's Kona Blue '11 GT. According to Chris, the factory gears are hard and (obviously) susceptible to shattering. We're upgrading the pump in Chuck's 5.0 with Ford Racing's replacement gears. The gears feature a softer metal compound and are more forgiving than the stock pieces when high stresses are imposed.
