HARLEY ’ S LATEST CRATE ENGINE IS EVEN BIGGER
Harley-Davidson has announced its latest Screaming Eagle crate engine for the Milwaukee-Eight platform , with the new anchor measuring in at a huge 135 cubic inches . That ’ s 2212cc for those of us who use real measurements . Designed for 2021 or newer Milwaukee-Eight engines , the Stage IV Screamin ’ Eagle kit was developed in part by efforts of the Harley- Davidson Screamin ’ Eagle factory racing team for their King of the Baggers roadracing campaign , and offers the most displacement and the most power ever created by Harley- Davidson for a street-compliant crate engine . Engineered and tested as a complete collection of high-performance components and assembled from the bottom up at Harley- Davidson Powertrain Operations in Menomonee Falls , Wisconsin , this street-tuned 2212cc Screamin ’ Eagle Crate Engine is designed to run with a wide-open throttle at high engine speeds and provide instant passing power from cruising speed . The engine delivers 193.8Nm of rear-wheel torque at 3500rpm and
130hp at 5500rpm at the rear wheel . That translates to approximately 28 percent more torque and 41 percent more horsepower at the rear wheel than a production Milwaukee-Eight 117 engine . That power is achieved not only through the larger displacement of the 135 , but also through a range of changes to the design of the Milwaukee-Eight platform . Compression is bumped up from 10.2:1 to 10.7:1 thanks to new forged pistons , while the engine breathes freely via a new 68mm throttle body and matching CNC-machined intake manifold , which was originally developed for the Bagger race engines . The 135 utilises Screamin ’ Eagle Extreme CNC-ported cylinder heads to help provide significantly improved efficiency of cylinder
