- Check out our Harley-Davidson Screamin Eagle 131 Stage 4 Crate Engine Upgrade Dyno with Horsepower and Torque video. We take a brand new stock 114 2020 Street Glide Special and transform it into a HorsePower Monster by dropping in the all new 131 Cubic Inch Stage 4 Performance upgrade. We do a baseline Dyno pull to see where the stock motor comes in at and make sure you stay tuned until the end to see how much power this beast makes.
We've got this bike on the showroom floor up for grabs and we're standing by to upgrade your current ride!

Brent! You just Dyno my 2021 fat boy yesterday and it produced 130hp and 150 torque! So happy with it! Thank you for building my bike!
Got to say if I was younger and rode it like I stole it a 131 upgrade would be awesome. But now my 107 with a Stage II on both my bikes works for me
I love how straight to the point this video is. Awesome!
Just put a 131 in my cvo....its a smooth power that you must ride and feel to understand. Love it.
80hp stock! Wow! A whopping 124hp after all that? It’s a crying shame that the HD community never warmed up to the V Rod. In stock configuration, it’s almost 130hp. And if you want to spend some coin, get a screaming eagle vrod (heads are already done) and toss a stroker crank in it. That’s all folks! Under 3k in mods and you’ll be looking at close to 200hp.
The numbers do seem low but those are wheel numbers. Most manufacturers advertise crank HP and Torque. Thanks for watching!
Vrods have like 110 to the wheel so
Wow, Harleys have always been beautiful and now you can actually get a lil adrenaline pumpin!
1:31 "They're not that much bigger"
1:56 "This is the biggest ring compressor I ever used"
:-)
I will line my R&R 131 up anyday against this 131
That’s a big bore kit ! Not a crate engine !
In Germany we have the „HyperTorxster“ kit by Sohn Motorcycles, 146Cui, 177lb-ft and 165HP ❤️
Will that motor work on a victory motorcycle?
no its a big bore kit for M8 engines
Now that's what you call an upgrade. 🔥🔥🔥
That's almost on par with the stock metric bikes.
You German’s sure do know how to build things and so mechanically inclined.
I ride an M109R which I love but I gotta give props; this motor sounds good! Ride safe everyone.
UA-cam recomended this video. I've got to be honest HD isn't my thing, they're not designed for British B road blasts after all, but that's a sweet sounding motor and that torque curve is frigging FLAT. I can appreciate the workmanship even if it isn't my style of bike.
Thanks for watching! Glad you enjoyed the video!
Great 'shop … a hive of Harley activity!
Thanks for watching!
It comes both ways Components like you see in the Video or as a whole motor i.e. "Crate".
Just got one. Thanks for the vid. Appreciate it
I was actually expecting better numbers than that. The 124 kits are making more, which is kind of surprising to me. I only say kind of because I understand that you are still using a Harley cam and tuner which is limiting the results by quite a bit.
Thanks for the feedback. We're happy with the increase and this thing is still under warranty so we're happy!
Plus it’s still emmisions compliant
That's a decent HP bump.
But still very anemic hp per cubic inch in the world of today's motorcycles.....
Since you're talking about horsepower....
Dam that torque is just amazing shift 2nd gear and spin the tire with no problem maybe even 3rd.
My friends who have that M8 Thrasher kit 124ci are getting 130+ HP and 135+Tq. I wonder if that Crate is cheaper then the normal after market big Bore. Good thing is since it’s SE ur warranty should stay intact
Thank you, random big-chested woman. :)
I’m sure the clutch pack has to be upgraded to handle the bigger HP?
The stock belt and clutch pack are used for this upgrade but the bike is still under factory warranty. Thanks for watching!
That’s it? Those numbers can be made on a twin cam with a 110 kit cams and a good tune.
Thanks for your input! We installed the kit and those are the numbers that we got.
Earl James no shit 😂 no one pays attention to warrantee or emotions after they do engine work, the whole point of the engine work and doing pipes and intakes and cams and big bore kits is to get more power, screw the emissions
My dyna street bob 110 puts out 106hp 122tq....man those m8 motors are so restricted in stock form.
Joe Plem that’s not even stock! That’s even with a 131 cubic inch motor! He should be getting way more power out of that thing
@@Ridehighfxdb These motors are not 100% sorted out yet so at least keeping the warranty is a good thing. Their is nothing like making payments on a bike with a blown engine and no warranty.
Great video , thanks for Real results on a Warrantied upgrade. Alot of haters out there saying they are putting up better numbers. But at what cost ? Wild cam that idles like shit , stupid compression so you have to run race gas ? Great job keeping it real , showing a bike you could ride anywhere, anytime !!
Thanks for the kind words! That was the point of this video is to have full transparency and to show what numbers can be put up with a dealer upgraded warranty backed motor! Thanks again for watching!
Is it a stage 4 big bore kit or the crate engine? Title says crate but your video shows kit
This build is a 131 Stage 4 Kit. There is a crate motor available with a 114 block and the 131 upgrade already installed!
Kinda amazed at how far upgrades have come since my 2003 Ultra Classic 88 upgraded to 95. Enjoyed the video, the Lady is right...LOL!
Did you just upgrade the brand new 114 motor to a 131 stage 4 and stick it straight on the dyno without running it in?
We did run it out and put break-in miles on the motor before stressing it. We just didn't film all those miles. Thanks for watching!
@@warhorseharley-davidson2214 and how many miles did you put on it before you stressed in on the dyno each time. Stock and then after the upgrade?
Good stage 4 114 or 117 with aftermarket Cams, tune, exhaust, heads and other parts make the same numbers or better. If I bought a 131 I better be getting 140+hp and 155+tq
This is a stage 4 114 motor upgrade. We realize you could get vastly higher numbers with this bad boy but we opted to maintain the factory warranty and put the bike on our showroom floor. It actually sold and I'm sure the new owner is going to do some pretty gnarly stuff with it!
So much depends on the dyno, conditions, and this still has a 2 year WARRANTY.
Its impressive no matter how you want to boil it down.
Bob Bob you don't seem to understand the purpose of this engine upgrade. It's EPA compliant and is covered under the factory warranty. The build you are describing is not EPA compliant and is not covered by factory warranty, you're comparing apples to oranges.
@@useryrock Who cares about the epa... There is a very small amount of riders that buy an engine upgrade because of epa. Theres only one state that is really anal about epa garbage and thats California, thats one state out of 50... Plus how many people do you really see following epa regulations in California, non. You see riders riding around with fish tail / aftermarket exhausts that aren't "epa" regulated. Warranty is another thing that really doesn't matter, depending what year bike you have the max warranty you have is 2 years. Who pays for your 131 engine when it blows up after the 2 year warranty is up, not harley. Harley bolt in kits are notorious for having pistons seize up and lifters breaking. In my opinion, I would rather take the risk of buying reliable aftermarket parts from good reputable companies than buying a harley 131 kit. An aftermarket company can get you part combinations that will last longer than a harley kit and out perform.
Nice. Was it just a big bore kit, did you upgrade the oil pump system and any transmission upgrades
I thought the same thing the whole motor but the numbers are not good enough for me did a stage four on my 2018 softail breakout got burned by the dealership they used a after market race tuner voided my warranty now am looking for a lawyer and the rest of the customers they did the same thing to it may take time but I have a lot of time
Is this a 131 Stage IV kit or 131 motor? Can you tell us what air cleaner and mufflers you used on this bike to get those numbers?
It is a 131 stage 4 kit. With screaming eagle ventilator extreme air cleaner. The exhaust header that comes with the kit and S&S slip on mufflers. And H-D pro street tuner.
I always prime my lifters and fill the push rods
Thanks for making this great comparison video 👍🏻
We had fun doing it and look forward to making more performance videos in the future! Thanks for the kind words!
Wow after watching this video, I can truly say the 1250 rev-max is an amazing motor. 1000 cc smaller almost as much power.
Vic'jville Awesome Motor Build👍
I thought the torque line would be flatter than it is. it doesn't seem to reach peak till after 3,000 RPMs, and is already falling at 4,500 RPMs. Maybe it is a tuning issue. I'd be curious to know how much you are charging for the bike with the upgrade.
Thats some serious power gains. Whats the cost for that kit installed when you buy a new bike?
Give us a call at 352-732-2488 and we'll glad to get you pricing on upgrading! Thanks for watching!
Are you seeing any problems with the clutch slipping or braking apart with the 131?
Massive work shop
If it takes 114 C I D to make 80 HP. Than how does another 17 cubic inches create 42 HP more ?
Head porting and polishing, or compression or what can it be ?
I don't know and believe me I aint complaning !
My stage 4 dyna 103ci has 115hp. Im really not that impressed being that it's a 131ci
No shit. My 2015 street glide with stage 5 110cubic inch with racing clutch puts out 121hp/126lbs of torque to the wheel. It lays rubber hard.
Also these new bikes have traction control and you cannot delete em. I rather drift on corner than the bike controls it for me.
what kind of fuel millage are you seeing out of this upgrade in a street glide compared to 114?
You can get faarrr more for I'm guessing far less money. I've done it many times. I just did a 107 and got more horse and the same torque. No factory warranty though but the bike is an 09
Cant wait to see what the indian challenger is going to make once they release their big bore kit.🤔 .. bigger isn't always better I guess. Thanks for the review.
I guess we will see! Thanks for watching!
What challenger big bore! Some people give Polaris too much credit! Secondly once you add a aftermarket cam, the Screamin Eagle ported manifold and 6.2 injectors to this beast that’s after the warranty expires quite naturally there’s no reason why this motor should produce 140-150 plus horsepower! Polaris dudes need to realize that this is legal EPA compliant power! the rear wheel horsepower on the Indian Challenger legally is only 103-107 hp
FactJedi 10-4 on the Big BOREdom kit! Oh wait! Now that you mention it, that kit may have already been released! Liked that very much! :)
@@darrellmoore2499 so let me get this correct. Once you spend 3k or 6k for the kit or crate engine. Then I need to open it up again to add cams and heads and injectors so it can perform better? And spend another 3k or more? What is being left out is the cost$$ of the total build with a proper dyno tune .
Just go to Fuelmoto or star racing and get 150hp/150tq with a 124 kit. For the same $$. But but what about warranty. If you go to a reputable builder the engine will last
The ability of a well designed motor will always exceed the ability of a poorer designed motor when give the same treatments. The challenger out of the box has about 20 more horse than the m8 in this video. It wont take a big bore kit to beat this machine. $1500 worth of cams and exhaust to blow this 131" mill away and it will likely last twice as long. For everybody knocking polaris you should thank em. Without victory and indian youd all still be riding twin 88s.
I have a 2020 Low rider S with a stage 2 Cam and adjustable pushrods and am having a 131 kit installed. Do I need to have them install one piece original equipment pushrods or are the adjustable pushrods strong enough to take the increased Spring pressure
Hey Charles, that's a great question! Please give our Service department a call at (352)227-1606 and they would be happy to assist you with that answer! Have a wonderful day!
My friend, and your Uncle John would it be so proud of you If he was still with us. Peace, "Snipe"
Hello Snipe. I was a BT on LPD/AGF 11... Persian Gulf Canoe Club 82-83 Forward MMR
Bad ass bike man
Thanks! It is definitely a sweet ride!
@@warhorseharley-davidson2214 you're welcome
What’s the fuel flow difference say 48 mpg what ever is published for 114 vs 131? Remember it’s a long distance tour bike.
80 hp from a 114?
can you do this on a TriGlide?
Hey Is It Possible To Buy This 131 Performance Crate Engine And Buy The Rest Of Transmission And Other Parts And Build A Custom Motorcycle? Instead Of Buying The Complete Motorcycle For $20k And $6k For This Crate. What I Thought Is If I Buy This 131 Creat Engine For $6k And Other Parts For $10k And Build A Custom Design Bike. Is This Possible Or There's No Way Unless Buying A Used One For Cheap And Use The Parts And Build A Custom One? I Don't Know Much About These Stage Customizations Was Into These Bikes Like 6-7 Months And These HD Engines Looks Damn Good. Buying A New Bike And Getting Stage 4 Is A Lot Expensive Right? So I Just Thought Why Not Buy A New Engine And Other Parts And Spare Parts And Build A New Motorcycle With New Parts.
Hi friends, I have a motorcycle review channel in Spanish. I'm Mexican. Could you use part of your video for a review of the new 131 engine?
Thanks for checking! We like to keep all our content original and in house so we can't currently release any of our footage! Thanks for watching!
Running in?
It's not about the horsepower. It's the torque that counts
Why can't Harley Davidson get one horsepower per cubic inch from a 4 valve per cylinder, fuel injected engine straight from the factory?
garbage technology
Go with a non EPA compliant build. Fuel Moto 128's make around 150.
The sky is the limit if you're not worried about warranty or EPA lol. Thanks for watching!
How long did you wait before running it on the Dyno ?
We made sure to put some break in miles on the motor before running it on the dyno!
All I'm saying is, there's no replacement for displacement. HP fundamentals
WRENCH g boost!
So you achieved stock V rod numbers! Harley should have put the Revolution engine in the baggers, more power, no over heating, bulletproof reliability! These bad engineering decisions will be the death of Harley!
Not bad for a factory spec engine WITH factory warrenty. Can't wait to see what these do once the tweakers get their grubs on them.
We're happy with the numbers for a warranted motor...it will be interesting for sure to see what some people who aren't worried about warranty are able to get out of this bad boy! Thanks for watching!
Would have liked to see the dyno run start at 2,000 rpm but I'm guessing it's way over 100 lb/ft.
Hopefully this motor is stock with 2021’s
I couldn't agree more. Harley needs to cut the shit with all the Screamin Eagle add ons. Just make a fast bike to begin with like Indian does.
As soon as I win the lottery that's what I'm going to do is buy a Street glide with a 131. 👍
I can't wait 😥😀🤗
Sounds rad. Atleast the performance is there. If the handling of those chassis could get a noticeable update i wouldn’t have gone back to indian. Shame cause harleys paint is way better to gawk at.
my 120 jims dyna would it that big motor any day
Does it still have the ~105mph speed limiter? Idk if it’s a CA thing, but I bought a 2019 RGS, racked up aftermarket parts to a bike total of $55k, and they failed to mention the ~105 limited top speed from factory. It suckedddddd.
We wouldn't recommend going that fast unless you're on a track with the proper safety gear ;-) but all the Harley bikes come with a limiter at 110 mph. Thanks for watching!
War Horse Harley-Davidson For sure. I get it. Safety first, but open road and you just put legends front and back and went from a 114 to a 117st4.....🤷🏻♂️. It happens. She was a 99% perfect bike, and I only have that one complaint. That new motor looks 👌🏻, I might just do another build. Thanks for the content brotha.
@@shredcity7217 Good luck on the build if you decide to make it happen! We'll make sure to keep the builds coming here on our channel.
If you get it Dyno tuned, your top end will be your 6th gear redline!
Shred City get it Dyno tuned! Then your top speed will be your 6th gear redline.i can do 123mph in 4th gear on my 2018 road glide with a 117cu in. Dyno tuned engine
I’m getting one!
Why standing beside bike for before test and sitting on bike for after test? Plus no equalized break in? Amateur hour or what? How about exact apples to apples next time!
When we did the initial Dyno pull there was no problem. After the upgrade we did a pull with the new motor and the rear wheel was hopping with the added HP and Torque so we did a pull with Brent sitting on it. We simply chose not to include all of that in the video to keep it short and to the point. There was a break-in we just didn't show it. We're here to do a full transparent test and nothing else. We didn't skew any numbers or hide anything. Thanks for your input and thanks for watching!
@@warhorseharley-davidson2214 looking at the dyno chart you showed for stock, you could see some tire hop/slip
Are those before and after horsepower figures at the wheel or crank?
Since he was using a wheel dyno, it's at the wheel
Robert, really ???
Wish it would fit under a HD trike.
Nice engine though.
124 Horse power? What is this? The 1970s?
The screaming Honda CBX 6 cylinder ultra performance machine of 1977 had 85 rear wheel horsepower.
This has 124 at the wheel.
I have to wonder how much you need. Are you Batman?
124 hp but with 138lb-ft torque
wHy NoTT Pud A HelKatt EnGIen In I T ......
124 whp at like 5500 rpm. Liter bikes make 150 bhp at like what, 15k rpm? And absolutely no low end torque in comparison? This isn’t a race engine, it’s designed to run at low rpm’s cruising down the highway....
Can this be done to a Low Rider S 114?
Impressive 👍
Thanks for watching!
Sweet but I would not use that cam , I have a Tq cam that sounds way better then that, 18 Heritage Classic
I’d still go with Zippers Performance- 124 sleeper kit . More torque similar hp and most likely more reliable long term .
Check them out if interested. They specialize in Harley high performance and have been doing it for decades.
Zippier...??? I'm sure the people at "Zippier" Performance are getting a chuckle out of that....lol..
ozzie444 fixed it 😊
What's the mpg after the upgrade versus stock 114
That's a great question! We haven't done any more than break-in miles for this motor yet and we didn't take a baseline so we'll have to get back with you on that.
3XR5 Not myself, but definitely some people that use their touring bike to tour lol. 🤷🏻♂️
3XR5 haha. You sound like an idiot yourself. The dude asked such a simple question, and War Horse even said it was a valid question. In your eyes the guy is “plain dumb” just for asking. You’re so cool...too cool for me. Ride on brotha 🤙🏻.
@3XR5 Your mullet looks dumb.
3XR5 you are fucking dumb. If you toured on your bike ( if you even have one) you would be concerned. But I guess not because you ( if you even have a touring bike) probably club hope and try to look cool. But your not. You are a fucking coward that hide behind a keyboard a bother real riders. Foh.
We're seeing a shift going on with HD right now
They are definitely not the same I am a old school biker and when I walked in the dealership they thought I was some kind of freak. all of them in their nice pretty button up shirts.
@@rtkl13 they'll always know the real biker when they see one ( old school biker) and I'd think they'll look at them differently cause they're different than the fashion guys . Ride safe man 👍
@@evil_musclemuscled3814 ha ha yes they do seem to want to ask a lot if questions from you
Howd you get the 131 when they dont ship untill March?
Nvm I see your doing the se upgrade not the actual crate engine, my bad
Stage 4 103 can make them numbers
My 18 heritage 107 " has stage 4, was dynoed with 122.37 hp , 120 lbs torque.. with the SE 515 high lift cam. I dont like this cam.. Needs a more torquey cam at low rpms..
What's the exhaust on this
AMAZING!!!! 😂
Can this kit be installed on a 114 tri glide?
This kit can be installed on a 114 Tri Glide but unfortunately it won’t be under warranty.
@@warhorseharley-davidson2214 Is the labor of the install under warranty or is just pay and hope for the best lol
@@warhorseharley-davidson2214 why would it void the warranty?
Now don't get me wrong I love Harley Davidsons they're awesome bikes but to pay $30,000 for a fully equipped motorcycle and then have to pay another 10 or 15 grand for a motor upgrade just to increase the horsepower is crazy I have an 08 Suzuki c109 with 124 Factory horsepower and with just a few hundred bucks I got another 15 horsepower out of it and I'm only 6500 into it now I know it's not a Harley Davidson but I'm an individual and don't feel the need to be included into some kind of Club of acceptance plus Harleys are crazy money
plus you have to look mad all the time when you ride a harley...so exhausting
Nice!!!
The 120r got more power than the 131.
Fast brake in.
You can talk shit when you learn that it's a break-in period not a "brake in". A for effort though!
@@andrewcsepany2742 Shut the fuck up moron. Everybody knows what in the hell Richard is talking about...
@@elonmust7470 Boi go suck one and catch some more crappies
I realize that's a lot of torque, but seriously, it still only makes about the same HP as a Japanese 600cc bike? I think it's stay stock and if I wanted speed I'd buy something built to go fast.
Jim Bennett How many 600cc bikes make over 120 hp? Which ones?
@@MadLadsAnonymous, well off the top of my head that's the 2015 to 2017 Suzuki GSX-R600. It makes 125 hp (93 kW) @ 13,500 rpm and that's to the wheel, not at the crank ;-) most of the newer 600s make at least 110 rear wheel hp 120hp isn't unusual at all anymore.
Jim Bennett interesting! I know the CB650R makes like 94 at the crank. Sounds like you're referring to SS class bikes? Thanks for the clarification.
@@MadLadsAnonymous, oh yeah, I should of have mentioned that. They've been really getting stronger since everything is fuel injected now. A lightly tuned GSX-R a friend of mine had put out 159hp on a dyno pull at bike week last year. That thing will run with his stock Yamaha R1.
Would that still be 108 miles an hour top speed
Unless you disable the limiter, the top speed is limited to 110. We're keeping this bike under factory warranty so we did not disable the limiter. Thanks for watching!
I have a 2019 fxdr with a 128 kit after market heads cam tuner. I'm making 140hp 153q to the wheel.stop making power at 6200rpm. My setup cost 4500 too boot. My warranty is gone but was willing to part Ways with it. I can say that have a muscle cruiser unlike before.
Those are solid numbers! Sounds like a pretty awesome build! Thanks for watching!
Crazy the T-man 128" makes more HP/TQ.
Is it epa compliant ?
John any aftermarket big bore kit will make more. But most aren’t epa compliant, and none have a warranty.
Yeah it’s just the screamin eagle epa tune restricting the AFRs
0 day warranty. Good luck
Lots of twin cam 117 ‘s making way more than that
Could you have a 107 m8 and bring it up to a 114 m8 then make that into a 131?
The stock 107 has a SE Stage 4 Kit that upgrades it to a 128. We should be releasing a video soon on one we're building so stay tuned! Thanks for watching!
Why dont all Harleys come from the factory with the 131? I'm a girl and ride a K1600B with a Remus exhaust and it's sad to see my girlfriend's on their Harleys struggling to keep up. I am aware of the culture of Harley Davidson and they are beautiful pieces of machinery but they gotta step up their game. The ride the lighting the performance is all dated.
come ride with me on my Harley 138ftlbs 134 hp
Will a 131 ci. fit in a breakout?
@gemini232003 ok, thanks
Make it stock from the factory
Never going to happen for so many reasons.
Is the 131 regulated @ 110 mph?
Yes, all the bikes that Harley put out are regulated at that speed so we left the regulation to keep the warranty in tact. Thanks for watching!
Can you do this to a 2020 low rider s?
Not yet...
This is almost 2.2 litres. Put a Vmax 1800 motor in one of these baggers, you'll be running 9s
DennisH22A the VMAX is a liquid cooled 4 cylinder that makes max power at 9k rpm. This is an air cooled V twin. I’m sure somebody stuck a Lamborghini engine in a Harley once but that doesn’t mean that it’s a good idea or that I would want to own one!
I have to agree with you on the v max 1800 motor, it would probably blow the doors off the 131 big bore kit. Besides that's a lot of money for a motorcycle, let alone a Harley.
Should be able to get at least one pony per inch.
yet a s&s 124 will still make more power with less displacement....
nick difference between non Epa and Epa compliant.
Yup was just thinking that.
Harley always pussy foots around.
Love my 124 though
Not to mention the SE kit is under full warranty... these guys know you’re gonna test the limits on these bikes... let’s be real here.
@@brycepace3498 EPA has them hog tied.
@@marconickolasgarces Actually they're counting on the opposite.
Maybe it's just me but why the need for more horsepower? If you want to go fast move to a sport cruiser or sport bike. And you can only go but so fast before the cops give you a nice fat ticket! I don't think it's worth it.
Tom E if you have to ask.....
Wow, so for $40,000 you can get a 120hp Roadglide 131ci, or for half the price, get the Indian Challenger that also has 120hp, HD is truly BONKERS, the Roadglide looks better, but not $20,000 better.
