Ford Racing 50L Motor Coyote From Hell
|
15 Run with the Comp Stage 2 cams, Accufab throttle body, and Hellion turbo system, the turbo 5.0L Coyote eventually produced 844 hp and 780 hp at a peak boost pressure of 14.2 psi. Inadequate valvespring pressure created a valve float issue that limited both available engine speed and power. With adequate valvespring pressure, calculations tell us that this same combination would produce near 850 hp at just 10 psi of boost (at 6,600 rpm). Look for increased valvespring pressure when we upgrade to ported heads in our next installment, but how do you complain about over 840 hp and 780 lb-ft of torque? View Related Article
