We've been pushing the 2011-2012 5.0 Mustang's performance envelope pretty hard lately, trying to find generate as much power as possible from the new, Four-Valve V-8s, and also seeking to determine where "limits (breaking points)" are, for the internal hardware that makes Coyote engines darn good.

We haven't reached that point...yet...But, when we do, we're glad to know that companies like Manley are on the case with more-than-suitable replacement gear.

Details on a new piston forging are after the jump...

Manley Performance has expanded its “Plantinum Series” of premium forged aluminum pistons to include applications for Ford’s new “Coyote” V-8 engine.

Builders of 5.0L DOHC (4-valve) “Coyote” engines can take advantage of pistons with an 11.5:1 static compression ratio (+6.75cc dome) or 9:1 (-12cc dish) that’s ideally suited for power-adders. They are offered in 3.630, 3.635 and 3.640" bore sizes for use with 3.650" stroke cranks (5.933" rod length).

As with other pistons in Manley’s “Platinum Series” lineup, the new slugs are forged from highly regarded 2618 high strength alloy and are designed to provide the necessary strength at minimum weight. Machining is done exceptionally close tolerances and perfect ring groove to skirt squareness (perpendicularity) is assured.

An offset wrist pin design provides quiet start-ups, and premium chrome moly wrist pins (with round wire locks) are included. The pistons have a pressure balance groove and are designed to accommodate +1mm larger valve sizes.

Manley Performance also manufactures stainless steel valves in varying sizes for the Coyote 5.0 engine.
