M8 Harley Cam Comparison - Zippers 468 | S&S 465 | Feuling 465 - Kevin Baxter - Pro Twin Performance 

One thing i didnt mention that I thought I had. Much of the extra power made by the S&S and Zippers cam could be due to another factor...to properly tune with a cat installed in the headpipe, the AFR should be a bit leaner than without to avoid overheating the cat. The leaner mixture could also have created an increase in the numbers. All this said...the manufacturers test their products and all we can assume is that they published the highest number they obtained in their testing with the stated equipment. Main point of the video is to illustrate again, how the cam specs effect the final performance and characteristic of the curves, and what each means. Hope you enjoyed it.

Learning a lot about Harley M8's, You, appear to be meticulous Engineer / Mechanical Engineer, I am 81 yrs. old & Harley Rider/ builder, and impressed! Have a great day! Kevin I Spend many hours watching learning, listening, and remembering all the wrenching! Thanks for the sharing!!

I would love to see this same video but add in the Woods WM8-22X-E

Zippers all the way I managed 115hp and 128tq on my 2021 softail standard

I started following you about 3-4 weeks ago. For a guy who finds things like this incredibly interesting no one explains it better than you. You are a wealth of knowledge Kevin. Keep up the awesome work

Had to watch it three times but the way he explains it, makes it understandable

Personally, I'm going with the S&S for my 107. It offers a huge boost in torque and power over stock, but as my only mode of transportation and something I rely on 100% of the time to get anywhere, I don't want to overstress the shit out of the engine and worry about it blowing up after 30k miles.

I wish you were closer! I want you as the only person that touches my bikes... you are very well versed and a master of your craft. I enjoy your videos quite a bit!

Makes perfect sense, as it should. One of the easiest straight to the point ways to understand cams video I have seen yet. Thanks for the knowledge Kevin, always a pleasure to learn from a pro.

Kevin...thanks for that break down. Looks like I made the right choice in cams 7mos ago. I have a 2018 Road Glide Special. When I bought it I had a HD Stage 3 build done basically bumping it up to a 114. Everything used was HD except for the headers which were FuelMoto Jackpot 2-1-2. I used the Screamin' Eagle 4" Street Cannons & Screamin' Eagle Street Tuner. I ONLY went this route for warranty purposes. Respectively the dyno showed 113.84ft lbs tq and 109.24hp. This past April my factory warranty expired and I decided to install the Zippers 468 cam, S&S adjustable push rods, S&S billet tappet cuffs and S&S high flow oil pump and cam face plate since I was already inside the chest. I swapped out the mufflers to Vance & Hines Torquer 450 then had it tuned using PowerVision. I ended up with 140.33ft lb torque and 122.94hp. It is a beast now. A torque monster that hits hard at about 2750rpm all the way up through 4000rpm. I mean it is a rocket strapped to your ass when you twist that throttle!!!! And the "thump?" Yea...you can hear it!! Lol. Can't complain with the performance of this cam. This bike now has 50,500mi on it and gets ridden!!!! I don't beat the day lights out of it but she's also not treated like a queen either. Definitely recommend this cam to anyone who wants a good bump in torque.

Excellent video explanation of how critical cam choice is. The M-8 motor HP is held back by low RPM operation. In your video building torque earliest and holding onto it longest, makes a very streetable, enjoyable bike to ride. Good Dyno numbers for a stock 107. Excellent video Kevin.

Awesome video as usual. Thanks for putting out relevant, informative videos for us Harley owners.

you Kevin Baxter are the Harvard professor of HD engine theory and utube schooling.you explained and have shown all of us mechanics and non-wrenches, what is up in the world of cams for our bikes.THANK YOU.

For my riding style, 475C S&S....love the info...

2018 FXBB with a TBR 2 into 1 for the past two plus years. So I've decided to S2 and have been researching torque cams. Best and most helpful and detailed video so far. With my intellect I did have to watch it a few times to get things straight in my head but ended up being a really helpful video. Thanks very much, top stuff.

Thank you mr Baxter, that was a excellent tutorial , I followed right along 👍👍I too, believe the zippers would suit my desired performance goals, again, outstanding, I’ll keep an eye out for more of your videos.. excellent….

I absolutely love the way the S&S 475C cam made my m8 ride/sound

Excellent as usual! I love the way you present the facts. Keep up the good work.

Great and indepth explaination kevin well done keep up the great work

Another great video Kevin, so much info for picking the right cam

thank you for all your effort putting put this info out there.

Hey Kevin I have a 96 to 110 build and I’m gonna be running a woods 999-6 cam with .590 lift. On the fence about running roller rockers or not or just set of new S&S standard. Iv heard some people say yes and others say no and wouldn’t run until around.630 lift.I appreciate your videos and have learned a lot from them

Awesome thanks for the information!

Love your videos. Very informative. Your opinion on a low to mid range cam for my new 117 low rider st. Also, your opinion on using the stock cam plate, oil pump, lifters, and inner cam bearing. I will be using a fuel moto dyno jet tune. Thanks for you help, and keep those great videos coming. It’s very helpful to have someone in the know, offering opinions as compared to the usual tube video personnel.

Mr. Baxter, that was a excellent description , very, very informative, I certainly appreciate your time, and effort, thank you very much, with all do respect, I’ll refer to you as “ professor Baxter But seriously, that was extremely helpful 🙏🙏

That was awesome 😎 better than most movies 🍿

I love this video! I’m using it to try to learn which cam I want for my 107 m8 (solftail standard) I’m torn between the andrews m464 and the woods wm8-22xe

Woww!!! Such an awesome awesome explanation Kevin! I don’t find anyone on the RU-vid explaining things so clearly as you do. I just subscribed to your channel. Count me as a loyal follower! I just wish you had included the SE447 cam as well. A lot of people whose bikes are still under warranty are forced to go with it to avoid losing warranty!! I had to use the SE447 in my 2018 FLHTK due to this very reason. Keep more videos coming in. Cheers!👍

Enjoyed this video

Thanks Kevin great info looks like I'm going with the s&s for my bike along with all s&s components 👍

Kevin U are incredible. U made it easy for me to understand these numbers. I almost wish u could’ve included the woods 22x. But thank u for all u do u are a godsend

Awesome Kev. Zippers it is!! Well, when I get a few $$$ 👍 Take care.

12:10 Good to know! I'm in the minority of thinking my FXDR's exhaust and air cleaner actually look fine on the bike, so I left them on. Before dyno'ing the bike the Dealer URGED me to get a "less ugly" exhaust & air cleaner combo and showed their Screaming Eagle and Authorized Dealer Catalog (S&S, Vance and Hines, etc.) and said I'd be missing out on big gains if I stayed stock...I ignored their upselling attempt and bought an Intake Manifold instead. Imagine their surprise when my bike dyno'd higher than most other stage 2 114's they had done... 125HP/128TQ S&S 475 Cam Chest Kit with Dynojet Powervision

Mr Kevin Baxter, excellent job/great video. Always look forward to watching you’re very thorough and informative vids. Cheers🥃 from Canada. 🇨🇦

Have a twin cam myself but great information.

Great video

I went with an Andrew's m460 in my 107, it's a cam that seems to get no love. I think it goes great and with only 2 degree overlap and 20 degree intake closing I'm still getting great fuel economy. Everyone loves the 475 but it seems to drink the fuel and only really makes more than the m460 above 4500 rpm.

Thanks again. Good video

Great information video. I’ve been Cam Hoppin’ on my 131 M-8. Had a Zippers 468 in it for awhile. I just put in T-Man TMP-2652. It seems to have more power but it’s a gas hog...even without getting on it my best mileage is 33MPG. Seems to run hot too. I installed a Dakota Digital Gauge set at the same time. I’m getting head temperatures as high as 327 degrees on the freeway. The plugs aren’t white so I’m not running lean. They seem to be right. I don’t know what it was before I had the temp gauge but it seems awfully hot. Luckily I use Amsoil. I’m going to fashion some wind deflectors for the rear cylinder.

Excellent really good cheers

Great info, been watching your videos on the M8s for months. Have you done any testing with the Woods 22XE. Can't find those numbers (lift, int close, duration, centerline, overlap) for this cam anywhere.

I recently put the zippers 468 on my 114 with vance and hines power duels with harley street cannon slip ons. This really woke up the bike. The shop that tuned it said at the very top of rpm range it shows bigger injectors and air clean would provide better performance at that range. I bought the cam because of its mid range performance for cruising and also for using the bike in slow skills practice. Your explanation are great and if I get in your part of GA hope to stop by.

Badass. Great info

I love youuuuu kevinnnnn,now i know whos the best

Many thanks Kevin for this awesome Video! I will pursue the RS468 thanks to you! Another note. The only reason i switched out my stock chrome Exhaust pipe on my Sport Glide 2020 to V&H Pro Pipe in black is eliminating chrome. I believe Chrome belongs in the Bathroom xD. But hell, I didn't know that stock exhaust systems can actually perform equally as good as a "competition or whatever" aftermarket pipes. All those who wish to maintain lower emissions and decent sound to make the bike pass in the yearly inspections is very convenient too. Win-Win!

maaaaaaan after seeing this, i wish i went with the zippers 468 instead of the fueling 465 cam that came with my race kit. id like to swap cams , but after getting the bike tuned by the now retired "Doc." from Docs Performance with a TTS Master Tuner, I feel like im stuck. He did a Great job! 33k miles on my 2018 Road King Special ... My next venture would probably be a 124 sleeper kit from Zippers... ITS ONLY MONEY LOL

Great insight Kevin! Great explanation! When the time comes, I’ll go zippers and s&s cam plate and Oiler

Great video Kevin! Just one question though; If you want to achieve the Gnarliest, nastiest idle sound, what camspecs achieve that?

great video

Exhaust opening point at BBDC is an important factor in torque production. Lobe separation angle is also important. When looking at intake close as a torque factor lobe intensity is needed because we don't know the actual intake close, just at a .053" lift. Compression bleeds whenever the valve is not seated on the way up on compression stroke. Lift is relatively not significant when comparing these bolt-in cams with stock heads.Just my humble opinions

Awesome informative video as always :) thank you. Understanding cams a lot more now after that. I don't see/hear anything about Zipper here in Australia. Looks like a good cam with a lot of power 👍

All the harley dealers around me say the stock lifters are fine to use with an S&S 475, whats your take on this?

I put a 465 in my m8 and I like it. It runs really well going down the road and the acceleration feels really strong…. The idle rhythm has taken a lot for me to get used too though.

What about S&S 475 cam I know it may not be a good combination but I got a 2in2 Freedom performance I would like to have 475 in my 114 Breakout

Dang! Is there a video like this, on twin cams? I understand the principal, just like the discussion with the HD Zar

Nice video. Would like to see, 472 cams, zippers. Fueling

Which of the Three Cams would offer Best Reliability or Be the Easiest on the Bike / lifters etc ,Would it be the Fueling ? I'm happy Enough with Power But Would Ultimately Love to Retain Best Reliability, would Going with an SE torque cam be the Answer or Leave it As is.

I had the zippers cam in my 2019 cvo. I wasn’t impressed. I’ve heard this from someone else recently too. So on my new 2020 road glide I’m going w the S&S cam w Khromewerks 2:2 pipe. Heard great things from this. Only if I could get the JD cycle works to tune it!! He’s had amazing tunes w this set up

Kevin, I have a 114 heritage with 300 Eliminator slip Ons. Can I do a zippers 468 upgrade with this exhaust? I do not like noise

The higher the centerline number the wider the RPM range the lower the number the narrower the RPM range is. In cars a 114 CL is good for a long range of RPM. A 106 can is good for a sort track type car because it runs in a narrower RPM range.

I have the Woods WMB- 22X cam in my 2019 Road Glide Ultra, Fuel Moto, RTX two into one exhaust, dyno tuned Power Vision, Harley Ventilator Extreme air filter. What cam would you recommend?

Don Performance in Germany also advised that M8s like to have a CAT for performance gains.Im thinking about camming ny new RKS but keeping the stock header and hust using my KW 4.5inch slip ons.Is there a need to change the oil pump and cam plate?(inner cam bearing,lifters and pushrods will be changed).

Kevin I have a 2018 m8 I really want the zippers 468 do I need to do the cam chest and oil pump also .?

I'm subscribed to your channel from Japan. Thank you for all the awesome videos! BTW, what is your view of Screamin' Eagle cams? Are they too conservative for EPA regulation reason? Thank you in advance.

Outstanding explaination. Very informative. Thanks!! I have a 2017 Road Glide Special with a 107. I am making my final decision on whether to purchase TMan's 128 big bore kit with HPI throttle body and intake 62mm, along with probably roller rockers. Deciding on which oil pump/camplate to use...either Fueling or S&S?? I want the torque to jump right in around 25k and have a nice bell curve without any loss's thru 4.5 to 5k. If you would sir, what can do you suggest along with a header pipe and muffler? I'd like to see a stout 145 or 150 torque and HP. Thanks!

I'm sure Fueling choose the best exhaust for their final results

Never understood why you'd buy a $20,000.00 dollar bike and immediately spend another $4000.00 to supposedly provide more performance. There is not a metric bike out there that would require such mods.

Good video, very informative,is woods in the M8 game?

Does this mean that the D&D Billed Cat exhaust is a bad purchase? I ride a 17 Road King Special, with a 107. I recently found a deal on the D&D exhaust. I was only planning on upgrading the air intake, exhaust, and tuner. Does the cam need to be replaced as well for best results?

Awsome stuff if I have a 95 inch on a 99 twin cam ., she really comes , salad after 4 grand .2@1 pro pipe . But. Yet rolls great on low end . , cam you say what # cam ? Erd head , helps?

kevin which one is the best cam (117ci CVO RG) Please advice

I have installed a s&s 465g torque and want to know what it equivalent is in it he SE range as my Se pro street tuner doesn’t list my cam un surprisingly?

Did you ever compare the aftermarket cams to the Screamin' Eagle cams?

This was three years ago but has anything changed lately.

Can you do a video on a cam selection for an exhaust that is form over funtion.... fishtails on a 108

When we choose the stage 2 for the 114, which cam is installed for more torque?

I like a cam for torque. I went with Harley's screaming eagle torque cam as I was under warranty. it feels fine. would been nice to have had it as a comparison. also I wonder how the feel is when you upgrade. does it take a big difference to notice. just curious. so if you go up 5 can you really feel it. or is it over 10 maybe.

Great video, thank you. If the Zippers cam produced those numbers with a stock headpipe and slip ons then there seems to no point to buy a complete exhaust system. The only reason to buy a complete exhaust system would be for the sound. Am I missing something?

My warranty for my 107 FXLR is almost over. Is adding a DND FatCat exhaust and Zipper cams or SNS plus a full air cleaner going to hurt my stock MC or make it better.

Around 3:30, I think you misspoke, as we know (and you had even just said) , intake closing builds cylinder pressure and hence torque, but you said with the s&s having the earliest intake closing will have the lowest torque. Seems the opposite. You paused and it seems like you might have just got things backwards in what you said versus what you were thinking. Anyway, I like the videos and only wanted to point that out because it was confusing and I replayed it several times to make sure I didn’t hear you wrong.

Can anyone answer this: SE Stage 2 Torque cam or Feuling Reaper 465 for M8 FXFBS. PLEASE.

still don't see the bat you keep referencing

First let me start off I am hardcore Harley-Davidson van but always make me wonder when people spend 30000 or more on motorcycle and then first thing they have to do is to upgrade it to make a run with even I Goldwing??

Pretty sure my brain just got smarter !

Very flat Dyno printout...must be different format to whats used in Aus.

Man i'd be pissed if I bought an M8 107 and put a S&S Cam in it. I've got a TC103 with the SE pistons, SE heads, SE 234E cams and a D&D Fatcat 2 into 1 pipe and I'm doing 96 HP and 108 TQ. It's on a conservative tune with a Harley Race Tuner. I'm guessing if I put SE 100 HP injectors, the bigger throttle body and manifold and tuned it I'd probably be in the 105 HP and 120 TQ range. You've pretty much just inspired me to find a nice used 103 Electraglide for a touring bike. Really no reason to buy a M8.

Why don't these engines come with better cams from the factory?

🥴wow
