H-D Milwaukee-Eight® 107" Camshaft Shootout

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.

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 WM8-222 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.

Nice review!
I wish you had tested the S&S 465 cams too...

 

[Pullersboy]

Good stuff! Thanks for sharing. It's great to see the results side by side.

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.

what does "Cam Lope at Idle" mean? is that the sound of the cam through the pipes at idle? or is that an internal thing?

if that is the sound of the engine idle, which i think it is, this is where I am confused. On the redshift 468C cam, that thing sounds low and slow really good.. but your lope description is Semi Aggressive? What does aggressive mean or moderate?

thanks for the help
