5.4L Modular Motor Intake Manifold Test - Factory Fast Vs. Advanced Aftermarket
|
Basically a single-plane carbureted intake, the manifold from Sullivan Performance was run with injectors and a 90-degree elbow fed by a 90mm Accufab throttle body. We hoped to run it with a carb as well to demonstrate the power differences offered by the fuel atomization (which cools the intake charge), but time did not allow for such testing. Equipped with the Sullivan intake, the 5.4L produced 458 hp and 395 lb-ft of torque. View Related Article
