H-D Milwaukee-Eight® 114″ Camshaft Shootout

In our second round of Milwaukee 8 cam testing we put the same SIX different bolt in camshafts to the test that were in our H-D Milwaukee Eight 107 cam shootout last month, however for this test we installed them in the Milwaukee Eight 114. Our test bike was a 2018 Harley-Davidson Fat Boy 114″ Milwaukee Eight and the bike was equipped with a Fuel Moto AC/DC Stage 1 air cleaner, stock head pipes with non-catalyst slip on mufflers, and each cam was fully tuned with the Dynojet Power Vision. The following cams were part of this test:

• Andrews M460
• Cycle-Rama 460
• S&S Cycle 475C
• Wood Performance-WM8-22X
• Zipper’s Red Shift 468
• Wood Performance WM8-222

The first dyno chart below has all six of the camshafts overlaid to show their respective torque and horsepower relative to this particular set of components. All of the camshafts in our test offered excellent performance increases over that of the stock camshaft, most interesting is each cam took on a bit more of its own direction with the larger displacement 114″ engine compared to the 107″ test. As we started our test we found immediately that the exhaust we originally planned to test with was not up to the standards we were looking for, we spent the first day working on exhaust systems, baffles, and different setup before we came up with a combination that would work for our testing. We also found the stock Ventilator air cleaner was not sufficient, so we replaced it with the Fuel Moto AC/DC Stage 1 (stay tuned for a future M8 air cleaner test). We would welcome you to contact one of our technicians at 920-423-3309 Mon-Fri between 9-5 CST to assist in finding the best camshaft to fit your particular riding style.
