I took my Dodge Demon to the dyno again, but this time my Demon is equipped with the RACE PCM and High Octane Race Fuel. I went back to Gear Heads and used the exact same dyno to get the most accurate results that I could. I wanted to compare the new dyno results with my 2015 Dodge Hellcat and show you guys the differences between the two on paper. Taking these results into consideration I feel that the Dodge Demon was well worth the cost, but I love both cars. I was really amazed at the difference that the race fuel made on the dyno.
I want to thank Jim Moore, the VP of Reeder Distributers for meeting with me personally and giving me advice on what he personally felt was going to be the best race fuel for the best results on the dyno. He is a great guy and if you're looking to get high octane race fuel in the DFW metroplex then I highly recommend his company!
I also want to thank Travis from Gear Heads for sitting down with me and helping to explain the results from the dyno and what the differences are. I know that dynos will read differently, but because I tested on the same dyno I feel I have a TRUE comparison between both my 2018 Dodge Demon and my 2015 Dodge Hellcat.
I want to thank service advisor Vince Williams, mechanic Luis Mascorro, and all the people from Meador Dodge for taking care of me. If you're looking to buy a new Dodge or Jeep then I highly recommend you ask for Kevin Eidson at Meador Dodge.

This dude should have a ton more subscribers. Who wouldnt want to see this?!
Outstanding video, left no questions unanswered. Great job
The guys at Gearheads are so knowledgeable.
MustangNthusiest ikr!!!!! left no questions unanswered
Incredible power from a factory car. Dodge and Srt team keep drag racing alive.
Dude your videos and car and content are freakin amazing 😩 haven't seen anybody else doing it like this with their Demon. Keep it coming man mad props 👌
MontbelloMopar 🙄
Sweet. I want a demon so bad.
Stunna the man. Thanks for all your help and advise.
WHAT A FUCKING BEAST ! 🔥🔥🔥🔥
Actually....spectacular runs..great video (he is the best imo)
but...math is off...the shop owner of the show doesn't have that right....
if you are saying 15% parasitic loss (which i think is reasonable...no argument there) and your RWHP and RWTorque numbers are 771 and 711, respectively...
then you DON'T x those numbers by 1.15 (ie 115%)
Mathematically you take rear wheel numbers 771/.85 and 711/.85
Doing that gives you 913 HP; 836Ft/lbs at the flywheel
As a check when you multiply 913 x 85% (ie 15% loss) = 776hp at the rear wheels (which is what the video showed)...and ditto for 836 x 85% (ie 15% loss) = 711 ft/lbs torque at the rear wheels (also what the video showed)
So...looks like the race PCM with 100 octane is worth roughly +85hp/over the stock ECU and 93 octane (not +32 as advertised).
IMPRESSIVE!
And in summary....
Real world (flywheel) Demon power numbers (assuming 15% parasitic loss):
828HP/780TQ (stock ECU/93 octane)...vs Dodge's lowball claim...808HP/717Ft/Lbs
913HP/836TQ (race ECU/100 octane)...vs Dodge's lowball claim....840HP/770Ft/Lbs
Thank you RoundPortII, this is exactly the reason why I love reading the comments. Based on your comment and mhmarch2's comment I'll be contacting Travis at Gear Heads and see his take on it. I appreciate the feedback and sharing of knowledge bro!
RoundPortII 15% of 776 is 116. Added that is 892. What am I missing?
RoundPortII Correct, this accurate. We want to know what 771 is 85% of, not what's 15% of 771. Great post.
RoundPortII no
Bad to the bone man! It doesn’t surprise me that the stated HP is lower than the actual HP. In the 60’s, Chrysler underrated all their muscle cars- for insurance reasons. Great car, look forward to seeing some drag strip footage👍🏼
The haters are real quiet on this one 😂
🙄
lol got em
Meh.... GT350 guys are getting more power adding bolt on superchargers in cars that weigh a lot less without $18.00/gal race fuel. It's simply a waste of time to criticize inferior cars like Priuses, Neons, and Demons. The important thing is that the owner is still having fun.
I’ll take a vette not this one truck pos
*trick
That monster is making 900 hp. Sneaky bastards! LOL. Amazing!
Great quality on the video keep up the great work!!!
Bryan Ramirez thank you Bro.
For anyone interested in the math because manufacturers give you "power at the crank" numbers... typical drivetrain loss is around 15% so for this to be putting down 776hp on the Dyno that is: 776 * 1.15 (+15%) = 892.4... or just a hairs breaths shy of *900 crank HP*
Jeeeeeeesus...
Incorrect. Your calculation would result in roughly 13% power loss. Increasing wheel hp by 15% is not the same as decreasing crank hp by 15%. You need to divide wheel hp by 0.85. It's simple algebra. Wheel hp = Crank hp * 0.85. Divide both sides by 0.85. Crank hp = Wheel hp / 0.85.
serturbo argh! Embarrassing, good catch!
I could care less. I was just correcting incorrect math. If you don't care or don't understand math, then move along.
maximus vonce you are just triggered cause you cant count thst high.
The math is off here. You should be subtracting 15% from the crank horsepower, not adding 15% to the wheel horsepower. That is 776.11/0.85= *913 Crank HP* A 13% drivetrain loss would equal 892.4HP at the Crank!
I think the drivetrain loss is closer to 10%, which still puts this Demon at 862 Crank Horsepower and still well over the rated amount.
what a beast of a car. those numbers are more than impressive. look forward to more great videos. enjoy, and keep the shiny side up.
Steve Heck yes sir, i will do it my friend. Thanks for watching.
Your the only channel that shows goood content of the demon
Thank you Miguel. I am planning on taking both my cars to the Drag strip and see how they compare.
770 to the wheels hot damn
Yeah Boy!!!
Congratulations on some awesome numbers. Looks like you’re Demon will get you into the 9 second bracket!! Thanks you for sharing another great video!!
The downshift at 9:58 got me on one knee begging for marriage. Lol amazing car man!
Betcha some of those good ol boys are saying: where does he get all his $$ to buy this shit! he's not suppose to have this.
Video quality is getting better! Also Thanks for the non clickbait titles, appreciate the honesty. I bet you are like me right now and are counting the days till the weather warms up!
Adam Griffin you are so right. I cant wait to get this car on a good track. Thanks for the compliment. I am trying to make better videos each time.
Dang so it makes more than advertised! Very nice job! Proud of dodge!
Oh shit! Thank you for that we all really want to see that.
Now, off to the Drag strip when the weather gets warmer.
Damn those are some good horsepower numbers not gona lie
Good News : Better than advertised. Gotta love that.
Thank you BDOG JR. Hope you liked it.
BDOG JR you see what they must of done was add the whp number they got to the chp number they got and divine it by 2. That way you don't disappoint them peeps at the dyno too much or impress them peeps using a more direct hp measuring method too much. You get the best of both worlds all car companies should do this.
Unless you put the motor on an engine dyno trying to add back an arbitrary percentage to guess the crank power is as useless as it sounds. Some dynos can measure the amount of drag in the drivetrain after you let off the gas to estimate the crank HP, which is somewhat reliable as well.
+Mohamad Al Yousuf thank you for input. I know numbers can be off, so I dynoed both cars on the same dyno to give me a base on the difference between them in power. Now to the Drag strip to see how they both compare in a race.
Great vid and info. My only suggestion less music while people are talking or when the Demon is rumbling. Music should be kept to intros outros & dead air. For muscle car enthusiasts it grinds our gears to have the beautiful v8 sound drowned out or interfered by music. Great work on your content and video transitions!
Online Privacy unless its classic rock or some metal lmao. that just adds to the kickass sounds
Dodge back at it again underrating their engines😂 Great video man! Keep em coming!
Thank you Jason.
Not to take anything away from your dyno results as I love the new Demon and wish like hell I could afford one but looking at the charts I noticed the results were STD-corrected and not
SAE-corrected. Just stating that SAE gives more accurate #'s than STD, which is usually inflated. Have fun with that beast and enjoy!!!
Yes! Actual proven results. Dodge has underrated this car's max power.
On a cooler days, it's truly rated at about 900 horsepower.
They can still turn it up even more, to hold the title. Can you imagine it tuned for E85?
Great video had before and after numbers and everything. Great numbers too.
To do 15% loss you take the rwhp number and divide by .85 since it is 85% of the total. That put the power around 913HP at the engine. 776/840 shows about 7.5% below rated power. That,is performing very well. Good job Dodge.
Only one out there putting demon content out love it 😍
Thank you for posting up the numbers. A dyno video doesn't need to be over 15 minutes long though... The power put down is excellent. The dyno guy still hasn't figured out I'm guessing that you don't have a percentage loss. The loss is a solid number. The Demon drivetrain will be around a 70-85hp loss with only a minor change as power goes up from friction. Even as a GM guy I certainly respect what this car was built for. By the end of this spring there should be a hand full of high/mid 9 second stock Demons.
Michael King thank you for your comments.
I'm sure you hear it a lot, but beautiful car man. You're very lucky to be one of the owners of a Demon. Thank you for your updates. I hope you get track time soon. Because you're a Demon owner I'm curious if you can answer a question for me. I see a lot running at the track on the stock tires. Can you order another set of Nitto's with the Demon logo on them or are you screwed once they are worn down. I would start with a fresh set of NT-05R's if you can't get another set with the Demon logo and put them away wrapped in plastic. The haters just don't see how special a car like this is.
The Nitto tires with the Demon face logo are only sold at the Dodge Dealerships. The next set of that I'm putting on the Demon are Mickey Thompson drag radials because I found they are much stickier than the Nittos on my Hellcat.
In the test I've done and my customers have done the Nitto's will hook as good as the Mickey's, but require a lot more heat to do the same job. The Mickey's will wear a bit quicker, but have a lot more hook up without the heat. The logo is pretty cool still. I really like that so much of that car is Demon specific. Thank you for that answer though as it is one that I've been quite curious about.
You're blowing up!!! Keep it g!!
Absolutely beautiful. Say what you want about the Demon, but all those ponies for 100k is the best deal in the auto industry. Exactly where American power should be. Not looking down its nose at the competition, rather, looking in the rear view mirror. Great video my friend. Be safe and represent us well.
Thank you. Will do.
Love this channel.
Thank you
The numbers are incredible!!!
I'm a FORD man,but would still like to congratulate you on buying a demon so the soon to be released gt500 has something to beat down on & not feel bad about it.😎
892hp/817tq??? Damn!!!
Classic Reaction that raise my heart there for a second too and this video really explains why Dodge said earlier that you can turn this car into any monster that you want. Plus I like how they said you can add any boost to the engine to push 1,000 plus HP
A SRT Representative once told me to use 20% drivetrain loss on cars and 25% drivetrain loss on the Jeeps. When you subtract the stock 704.05 from 840 advertise HP, it represent 19.4% drivetrain loss.
My stock 2014 Jeep SRT dynoed at 354.38, which represented a 24.6% drivetrain loss.
Add that 19.4% drivetrain loss to the Demon 776.11 Dyno number and you should get Crankshaft HP Rating of 926.67
Crazy, just crazy at the potential of this car, right out the box.
TheBlack ScatPack yep, that's the best part.
You have a new subscriber too bro. I can't wait to see what you do next.
Great video you covered all the bases very good! I love your channel keep doing your thang man and don’t forget my motto “Keep grinding and stay humble”!🤟🏽😎
Thinking about getting a demon 2018 this video makes me want it even more now
His math is wrong, assuming 15% loss you would not multiply by 1.15, you would divide by 0.85. Which would mean around 913HP. When you take out a percentage from something you multiply by the reduced factor, in this case 0.85, then to reverse the loss you would divide by the same number.
Thre89- I noticed his math was wrong also as soon as he multiplied by 1.15. I hope he reads your post to understand how to get the correct crank HP. I'm quite surprised how many guys here were fooled by the math. Actually as I read some other older posts, a few guys did mention the correct math. 913 HP is awesome.
my new favorite channel
Nice work! That car is a beast!
Great vid man, I'm living vicariously thru you, so Im loving the details!!!
Larry S. Okay. In that case, would you run both cars(Hellcat vs Demon) at the Drag strip with similar set up, seats etc, or strip down the Demon minus seats etc and go for 9's?
Demonology you have to go stripped down to see the full potential, and would be great content for us
Very nice. I've raced my Vette against a Hellcat, but I have not yet been able to find a Demon to run. Realistically, since I do NOT have a drag suspension, I expect the Demon to beat me off the line, of course. The question is whether I can reel it in with only 1/4 mile. From a roll, which would significantly reduce or eliminate the traction issues, I should be able to beat it.
does anyone know the difference in the 2 air filters?? besides the the little size difference "air grabber" part?? great video buddy keep it up!!
That’s awesome dude! Dodge always underrated there horsepower numbers.
The intakes I bet net the same whp on a dyno LOL!
Awesome video and beautiful car
Thank you
Damn that thing sounds mean!! Love the car and vid keep up the good work!!
Man great testing back to back dyno runs. Keep up the good work.
Thanks
teacherm96 , will do
That pretty cool , as a kid we used 20% loss through auto trans . Back in the day tho manual cars got a hotter cam
Very impressed with this car and the content on this channel, keep up the good work! Great music too!
Thank you Will Mac!
So close to getting wheelies
Thank you for showing us what the Demon can actually do! Great video!
@Demonology mane trust me your subscribers and views should be up there after you hit the track with this beast and after a year when you are flexing with this big boy. Btw I watch your video more than 2 times. 892.53 HP & 817.63 Torque 😱😳. That thing cool mane. Keep up the good videos my friend
Thanks bro, I appreciate it! I am glad you enjoyed the video.
Grate video man
Awesome video dude! I just subscribed and can't wait to see this thing rip down the drag strip later on!
Miguel Fernandez I am with you on that one. This weather needs to warm up so the tracks can open.
Very Cool Video! I was Fortunate Enough to Get a Ride in my Club Members...Golden State Mopars Demon! When he stepped on the Gas I Instantly New it would Kill a Stock Hellcat....Like Mine! I felt The Demon Has to be Amazing with the Crate PCM! Thnx for Answering what I knew and was Pleasantly Surprised with your Results! Great Video, Killer Content and Keep us Posted with your Experience in Your Bad Ass STOCK DEMON!
Thank you Reuben. Waiting for the weather to warm up so I can get both cars at the Drag strip.
Wonderful video! Thanks for making it!!!
Im so excited to see this you have no idea..
V8Ferrari thanks #SQUAD
Meador Dodge! I just traded in my Volvo S60 to them for a destroyer Grey 2018 Challenger R/T Shaker with a 6 speed. Great bunch for people there.
Corey I live the shaker so much. Before I purchased my Hellcat, I had a 2015 392 because I couldn't find a shaker for sale. I would love to meet you and see your shaker.
Demonology I’m down with that. There’s noting better than meeting like minded car enthusiasts. Especially in the DFW area. Just let me know when.
Would like to see this on a MustangDyno as Dynojets read high. Really loving the Demon though.
How about adding long tube headers and a hot cam?
Going to leave it stock and run the Hell out of it🤣🤣
That thing is burning hella clean, no backfire and exhaust flames. Healthy As fuck, should last you a long time, supercharger prob will go or need bearings 35k and under, so be ready to replace / rebuild the charger
😎
I like the videos you put out. I really wanted to see the SAE numbers though since the STD ones are usually higher.
Got a third gen camaro in Arlington that wants some action in mexico.
I was ready to come on here & talk shit lol I can’t say Anything bt damn those numbers are spot on. Good luck with your demon & keep up the good content 👍🏽
Did you run the pump gas through it with the 109 for a few fill-ups to get all of the mixed 93/109 out of it and actually run straight high octane? Not criticising, just genuinely curious.
Nice video but the air filter differences are probably like a 170 thermostat vs 160 thermostat you know. Is it gonna change something slightly yeah, is it going to be remotely noticeable at all, probably not. A great air filter to a great air filter
Love the Demon and videos! What's the song at 6:30. Want to use it for my videos.
Awesome!!
Good stuff and I was asking about the octane! But now took it to that bad ass level. And the right way!
Love this fucking channel love the demon
Geovani Vasquez 😍
I always said that the SRT Demon was Underrated by Dodge but a see that as a good think. Also keep up the Asome work.
There is no rule of thumb for drivetrain loss. And that is engine numbers with power train loss. The true power and torque numbers to the ground is well into the thousands.
Love your videos I swear to god
Thank you Bro
DEMON! #DodgeBrothers
Anyone else hear hypnotize playing in the background?
Idk about the 15% loss, should be more like 18-20% loss if the transmission is high efficient like the guy says. Since normal is 22-25% loss for a automatic
That demon is so nice I would get one if i wasn’t poor and wasn’t 15
that new air filter was insane! without that you can forget about any power beyond the stock one.
This is great! Thank you for sharing
NineOneSix Blvck thank you for watching
That means it’s making like 915 hp crank?!
Danny Russo or 840hp haha
Far North Squirell it’s definitely making more especially if it made 776 to the wheels
Ok fine 892hp to crank
Far North Squirell yeah over 50 more hp than advertised. That’s crazy
Danny Russo that's the Mopar way
I call it the speed demon!
Great Video!
Nice work again on the part 2 dyno video!
wow! imagine someone paying $147,000 for a Demon and it only gives them 100 WHP more than a $70,000 hellcat. some people have more money than they should.
Awesome video boss
Incredible Hemi thank you
You should use Race Gas concentrate. Cheaper and easier to carry around.
Your one lucky man... I know deep down it’s not as much luck as it is just old fashioned hard work. I run a small cleaning company and work very hard and I’m also a 100% full time father as of Jan 2017. And being a father and being true to my priorities, I just couldn’t pull off the purchase of this car and it really really breaks my heart because this is by far the most gorgeous car in the WORLD. I wanted one so bad in the exact color you got, I feel almost forced to get one knowing what’s is to come in the future for muscle cars. I just really hope finances will allow me to atleast get a low mileage Hellcat before it’s to late. But as always little one and a roof over our heads will always come first :/ .... sorry about the rant it just hurt to not have something of this caliber when I did everything in my power and will to pull it off. Beautiful beautiful car tho sir, you have taste.
Hello Cheta in 5 years, there will be something just as good. Small goals equal big rewards. Stay Hungry, and keep grinding.
It's got alcohol in it that's what it's cuz it's going to carry moisture out of the air into the engine
Great video
Dope car
😎🇺🇸 Hey Buddy Can’t get enough of the Demon 👍 great video fun stuff. Great Dyno numbers Peace ✌🏻
Beautiful car....!!
26 ford and chevy guys scared of said Beautiful car.....:D
You do know that yellow piece on the front splitter is to protect it from shipping right? Not made to stay on the car
Yes I do. I had it removed from my Hellcat, and put it back on after I scrapped the front spoiler. Besides,i really like the way it looks. Just me. I know alot of other people don't like how it looks, an I am fine with there opinion. Thanks for explaining what it is.
Great numbers. I bet if this car was on e85 it would hit 850hp easy. Great job to everyone involved with this car
mike reed ummmmm I don’t think you comprehend ‘race gas’
What they put in has higher octane than e85
mike reed Lmao, 85 is 104 octane bud. MS 109 Race gas superior to 85.
The Demon is not able to run on E85
Demonology even if you put a flex fuel system in it or tuned it for e85?
