We tested SIX different bolt in camshafts back-to-back to provide an accurate comparison of results. Our test bike was a 2017 Harley-Davidson Road Glide 107″ Milwaukee Eight and was equipped with a Screamin’ Eagle Stage 1 air cleaner, Jackpot M8 2/1/2 head pipe, S&S MK45 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 significant performance increases over that of the stock camshaft. 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.
Andrews M460 Camshaft
Valve Train Noise: Very Quiet
Cam Lope at Idle: Moderate
Description: This cam makes nice broad power. It comes on relatively early and pulls well to the right side of the curve. This cam placed in the middle of the test.
Cycle Rama CR-460 Camshaft
Valve Train Noise: Very Quiet
Cam Lope at Idle: Moderate
Description: The Cycle Rama 460 made very good low RPM power (the second best in this test), it also provides a very broad power curve with good upper RPM power.
S&S Cycle 475C Camshaft
Valve Train Noise: Very Quiet
Cam Lope at Idle: Very Aggressive
Description: The S&S 475C made the second best peak HP in our test, it accelerates hard. It is very responsive and has the most aggressive lope of all the cams we tested by a significant margin.
Wood WM8-22X Camshaft
Valve Train Noise: Very Quiet
Cam Lope at Idle: Aggressive
Description: The WM8-22X camshaft offers the best early torque in this test, and it faired well horsepower wise. This cam is easy to tune and has an aggressive lope.
Zipper’s Red Shift 468 Camshaft
Valve Train Noise: Very Quiet
Cam Lope at Idle: Semi-Aggressive
Description: The Red Shift 468 placed in the middle of our test for both peak torque and horsepower. It has really broad power, nice and strong through the mid RPM’s. It has a semi aggressive lope.
Wood WM8-222 Camshaft
Valve Train Noise: Very Quiet
Cam Lope at Idle: Moderate
Description: The WM8-222 made the best overall peak horsepower. It made slightly less early torque than the other cams. It has the smoothest curve.
