Simply comparing one cam to another isn't going to get you anywhere fast. You have to consider the whole system from intake to exhaust. It's no secret some cams respond better with one exhaust than another or vice versa. Some cams respond better to compression increases and that needs to be taken into account when choosing a cam. I chose to go with a Red Shift 468 and a D&D Billet Cat because the 468 was developed with a Billet Cat per Zippers. My bike dynode max torque at 2850 rpm. or about 75 mph. right where I wanted it on my '17 107 RGS. It was tuned with a Power Vision. The number was 126 but dynos vary. It held over 110 tq til 4900 rpm, but again that's just a number. It's torquey as hell and is fun to ride. I seriously doubt any SE setup could possibly compare.
There are quite a few cams that are capable of delivering similar performance to my Red Shift 468. Just remember the intake and exhaust need to work well with the cam that you choose.
My point is get a system from air cleaner to exhaust tip of parts that work well together!
So was interested to read about SS475; just had the SE447 put in my 19 RG 114. Already had Kromewerks 2/2, and ac and SE tuner (to keep warranty). I didn't notice much difference. My local guy claims if I let hime do the SS kit with 475 cam that the difference will be huge. Doesn't sound like it. I have a Thundermax tuner that I may use instead of SE tuner; hoping that helps. Just came off a 17 107 stage 4 that seemed much faster. Opinion if its worth changing tuner or cam without adding inches?
Damn, the shop quoted me 3k for the stage II today. think I will pass,
So I have a 2019 Road Glide Special. I did a stage 2 torque cam upgrade to my 114. when I 1st got it done, it ran great. Use to be able to pull up the front end in 1st and 2nd, and Im a 300 pounder. Now the bike won't pull under heavy throttle without spark knock. So I took it to Harley, several Harley dealerships for that matter. Everyone of them said nothing is wrong with it and that I'm lugging it at 2200 to 2500 RPMS. So I tied the Power Cam tune with the toque cam installed. The spark knock has subsided, but the question is, why was the spark knock existing? and 2 will the power cam tune harm the engine with the torque cam installed. I also have the wide band SE auto tuner installed, didn't fix the spark knock on the W006 tune. Seems to work with the W007 tune though. Any help would be most welcomed. Thanks.

So here is the dyno sheet that Steve is talking about in this post:
So now if you want to kind of see how the 447 compares to an RS468 you would have to look at these two charts and extrapolate.
You have to note that the first chart runs are fifth gear runs and the other charts are sixth gear runs. I imagine the two TTS100 runs would be about the same if both were in the same gear.
So in the first chart the TTS100 made 7 more ft/lb. of torque and 6 more hp than the 447. In the second two charts the RS468 made 5 more ft/lb. of torque and 5 more hp. than the TTS100. So I would say all other things being equal, the RS468 will make about 10 more ft/lb. of torque and 10 more hp. than the SE8-447 in an M8 107.
Interesting heres my 107 RGS chart, RS468 PV, FM header/outlaw slip-ons
My 2019 RKS Stage 2 all HD except exhaust dyno'd at 95hp 114tq. Very similar to these graphs.
Not trying to be an ***, but that aint that much better than stock. Mine came in at 91hp and 118 Tq. with just a heavy breather and a fuel moto pipe, tuned with power vision and no cam.
