3.6 Liter Kenne Bell Blower Shelby Pulley Mammoth
|
Here are top and bottom comparative looks at Kenne Bell's 3.6-liter twin-screw supercharger (left) and the Eaton 2.3-liter TVS blower that is standard on all '13 Shelbys. The obvious difference between the two huffers is the overall stoutness of KB's billet chassis and Mammoth air-intake plenum versus the 100-percent-cast OEM piece, and of course, the larger twin-screw rotors in the 3.6-liter. From a pulley/boost perspective, Kenne Bell starts with a bolt-on, 4.0-inch wheel that should promote roughly 20 psi of boost on the Trinity. The Eaton sports a press-fit, 2.71-inch pulley, which tops out at 15 psi. View Related Article
