E-Series Ford 5.4L or 4.6L Quad Stack Injection

HP RATING:

We rate our 50mm V8 Stack and Cross Ram kits at 580HP - 600HP. 

This, of course, does not mean that your engine will make that much power, but so long as the rest of the engine and tuning is up to it, this kit can support up to between 580HP and 600HP.

6° THROTTLE PLATES

In the past, 12° throttle plates were the industry standard.  The problem with 12° throttle plates, is that as the plates are moved off the closed position, the change in airflow is huge.  It makes it very difficult to drive smoothly at lower throttle openings.

6° throttle plates improve off idle and cruise driveability making your vehicle far more enjoyable to drive.

Butterflies are secured to centreless ground brass shafts and screws are loctited to ensure reliability and serviceability. All are fitted with bearings rather than bushes to eliminate axial shaft movement.

Low stiction bearings for sharp throttle response.
