mountune’s extensive knowledge of the Ford EcoBoost
engine coupled with broad motorsport experience provides the foundation for the
ultimate 2.3L Ford EcoBoost forged piston. Engineered in house by our
motorsport division and manufactured exclusively by our partner Mahle
Motorsports, the mountune Mahle forged piston set for the 2.3L Ford EcoBoost is a
fully featured piston with many of the same upgrades we use in our professional
Produced from modern 2618 lightweight alloy forgings
for extreme duty, each piston features supported pin
bosses to withstand the extreme conditions found in engines operating with high
cylinder pressures. The layout of the piston has also been optimized with
weight reduction in mind and reduced skirt profiles to minimize friction. The design also includes gas accumulator grooves developed during extensive testing
and tailored for the EcoBoost engine. Careful consideration has been used in
the “bowl” area of the piston to maintain Ford’s original profile to ensure
proper and efficient combustion.
Extreme duty 22.5mm internally tapered, short wrist pins
are used to reduce pin flex and weight. Mountune connecting rods are
recommended to ensure a matched set of components.
As an added feature, Mahle's phosphate dry lubricant
coating is used on the entire piston to reduce micro-welding and pin galling.
Additionally, Mahle's Grafal skirt coating is used on the piston skirt to
reduce cylinder wall friction reduction.
Hard anodized top ring grooves have been incorporated
for increased durability and strength to withstand the high cylinder pressures
of high boost engines.
- Gas nitrided top ring:
Superior combustion sealing, strength
- Gas nitrided second
ring: Superior strength and wear.
- Motorsport grade piston pin locks ensure reliable operation.
