Coyote 5 0 Engine

To facilitate slip-free boost, Ford Racing developed a unique 10-rib blower drive system spun by an ATI crank dampener. The team found it was necessary by maxing out the base kit's 2.3-liter blower and 6-rib drive to the point of slippage. With the 10-rib 2.9 and a 3-5/8-inch pulley, they hit their power target. Besides overdriving the blower by 20 percent, the ATI unit is critical from a durability standpoint, as adding a supercharger changes the torsional dynamics of the engine as much as stroking it.
