Long known for its Ford Modular and Coyote engine components, Manley Performance continues to develop new and exciting components for the world of the high-powered Coyote engine. New at the 2019 SEMA Show is Manley’s piston offering for the Gen-III Coyote from 2018-and-up.
“We have two different versions of the Coyote engine pistons,” said Trip Manley, Vice President of Manley Performance. “First is from 2011-‘17. We are doing a piston for that engine in three different compression ratios: 9.0:1, 10.0:1, and 11:1 — in multiple bore sizes.”
While that covers the Gen-I and Gen-II Coyotes, the dual-injected (port- and direct-injection) Gen-III requires a different design. “We just came out with the Gen-III piston, for the ‘18-and-up Coyote, which is a slightly different design. We’ll be offering those with 10.0:1, 11.0:1, and 12.0:1 compression ratios in a variety of bore sizes, as well,” Manley said.
“Both pistons are built to handle more power, with a thicker .200-inch-thick crown and the top ring moved .225-inch down from the piston deck, which will be less prone to lifting a ring-land at high boost,” explained Manley. “We offer a standard 2.50-inch wrist pin with a 150-inch wall, but we have a 9310 pin upgrade which a lot of guys go with when they are making any kind of power.”
All of Manley’s pistons come with Total Seal piston rings and are all manufactured and coated in its East coast manufacturing facility. In addition to pistons for high-zoot Coyotes, Manley also specializes in the corresponding connecting rods, with three levels of upgrade.
We have the Pro series, which is a fully machined I-beam rod that will hold 2,000 horsepower,” Manley said. “Then we have two lines of H-beam rods. The standard H-beam, and then we have the H-Tuff rod. That one is about 60-grams heavier [than the standard H-beams] and will handle more power. So you have a good, better, best scenario with H-beams, H-Tuff, and Pro-Series I-beams.”
Manley’s components aren’t just strong on paper, as proven by the fact that they have been used in the MMR Gen-X billet engine, which has gone 3.72 at 212 MPH in the 1/8-mile, and 5.80 at 259 MPH in the 1/4-mile.
