The Incredible TECH Behind the World’s FASTEST Dodge Demon

this is the fastest dodge demon in the world a 1500 horsepower eight second quarter mile demon that has twin turbos not only did this demon ditch its infamous supercharger it's got the full carbon fiber body treatment and we're not talking about cheap run-of-the-mill carbon fiber we're talking space grade top to your stuff that's right there's different types of carbon fiber and we're going to talk about it now the engineering behind the stock wheelie producing demon was already impressive but this one is even better and today I'm gonna show you why so let's jump in and take a look at the incredible engineering behind the world's fastest dodge demon aka now if you notice that I'm not in a typical bumper to bumper studio setting well that's because we're doing our part here at donut by not leaving the house so we thank you for watching the four Matt's gonna look a little different but we're still gonna give you some sweet videos with some knowledge and lots of chuckles dodge dropped their 3rd gen challenger way back in 2008 and more or less every year since then they've been releasing upgraded and faster versions of their Mopar inspired muscle car they make a GT n RT the scat pet bow and they even have an all-wheel drive version in 2015 they went crazy and released the Hellcat a 707 horsepower challenger and then in 2018 they lost their minds and they built the demon an eight hundred and forty horsepower street-legal freak of a car it was the fastest non electric car to go to 60 miles per hour from a standstill and the fastest to do a quarter-mile and the first production car to do a freaking wheelie dodj had built the most absurd challenger ever that's until speed pork and these guys now they're in the business of making super nice carbon fiber parts and building insane performance vehicles they always use the same very complex recipe reduce weight increase horsepower you can literally see that those are the two areas they focused on when building this car full carbon fiber body and giving the engine more power that's the supercharger delete' twin-turbo setup so those are the two things I'm gonna focus on today let's begin with the first part of their recipe and that's reducing weight by using carbon fiber [Music] everyone knows carbon fiber it's cool super lightweight it's strong it's Purdy but it's also expensive so it's impressive that this car's body panels it's bumpers its hood roof the fenders the doors the splitter everything is made from carbon fiber and by making all those parts out of carbon fiber the demon is six hundred pounds lighter than the stock body that's a 15% drop in weight from a stock demon now to put that into context your pelvis weighs fifteen percent of your total body weight so yeah imagine losing your pelvis you can't see my hips now there's a general rule of thumb out there in the drag scene and that's every hundred pounds you drop you also lose a tenth off your quarter-mile time that rule of thumb goes away as your car gets faster but the main principle stays the same and that means less weight equals faster times down the drag strip so dropping weight by using carbon fiber is a go-to method for reducing pounds but what exactly is carbon fiber now you hear it being thrown around all the time as this new age space grade material but in fact it's been around for a long time you may have heard of a guy by the name of Thomas Edison well in 1879 he invented the first incandescent light bulb now you probably know how a light bulb works and it's pretty simple right you have electricity that heats up a thin strip of material called the filament net filament glows well Edison used cotton threads and bamboo slivers as the material for his filaments after he shaped them into the size that he wanted even baked them and when you baked those materials you're basically carbonizing that material meaning you're making a carbon copy of that cotton strand he was the first guy to invent carbon fiber a carbon fiber is made up of very thin strands of the element carbon just a bunch of carbon atoms bonded together to form a long chain now these long chains they're extremely stiff they're strong and they're life and you can take these chains or strands of carbon fiber and you can twist them together similar to how yarn is made you take that yarn and then weave the yarn together to make a cloth or a sheet and this is the raw building material used to make carbon fiber parts even the way they weave the carbon fiber strands together can vary to give different looks and alter its strength properties now this is the front fender off my RC 51 my motorcycle and it uses a standard checkerboard pattern and you can tell it's a checkerboard because well looks like a freaking checkerboard so how do you go from taking carbon fiber sheets to carbon fiber composite parts like this one and that word composite is the second part of the equation and it's an important one that usually gets left off when we talk about carbon fiber parts we say carbon fiber but what we really mean is carbon fiber composite you see on its own carbon fiber is pretty brittle and it can break and crack and split fairly easily so it's suspended in a glue like material called epoxy resin before it's molded and turned into a part like this one an epoxy resin is what turns carbon fiber into a carbon fiber composite the resin does two things first it holds all the carbon fiber strands together and second the resin adds toughness and durability it's slightly plastic in nature which is good because it helps absorb sharp blows like a crash without creating any detrimental splits between the carbon fibers so that's carbon fiber great now what makes speed quartz carbon fiber so unique remember we talked about that epoxy resin like two seconds ago but there's a few ways you can apply that resin you can use it in the wet variety and pour the epoxy into the mold on top of the fiber even vacuum seal it and it forces all of the resin into the fibers and then you let it cure when it's done it comes out of the mold with a shiny appearance kind of like this now the more time-intensive and more strictly controlled way of applying the resin is of course what speedcore does and that's using a process called dry or prepreg carbon fiber and instead of coating the carbon fiber cloth by pouring resin over it dry carbon fiber has the resin coated on the fiber weave each strand has the appropriate amount of epoxy while it's being made it's pre impregnated now the ratio of fiber to resin is controlled throughout the entire sheet the prepreg carbon fiber is in molded and placed into an autoclave where it's cured so an autoclave it's just a pressurized oven kind of like a pressure cooker they use this because putting the part under high pressure and high heat fixes any irregularities the part may have now because with prepreg you control the amount of resin it weighs about 70 percent less than a wet carbon fiber part coming from the same mold it's now the wet process even when it's vacuum sealed ends up with an excess amount of resin and that extra resin is extra weight on the other hand it costs a lot more to make parts with prepreg when you go on flea bay and look at carbon fiber parts coming from China 99% of the time they're gonna be of the wet variety and even then the resident is just painted on and not even vacuum sealed they just freakin slap present on there heat it up and cure it and that's it not a lot of quality control there they also cheap out by using only a single layer of carbon fiber and then backing it with fiberglass my fender on my RC 51 that's what they did and I know that because I can look inside the part and I can see the fiberglass it's opaque so you can literally see light pass through the carbon fiber and they try to hide it by spraying this section black but I'm no dummy and now you're not a dummy because now you're gonna know someone sends you a fake carbon fiber part this is a good way to check hold it up to the light you see light through it so they try to paint and hide it if they did they were bunching okay went off-script a lot there I'm sorry but speak or they didn't skimp out they use the best of the best when building their demon it takes about 200 hours to make an entire body panel swap for the demon every piece is handmade right here in a good old US of A am i taking every panel fender and bumper and replacing it with their own carbon fiber piece it drops another 600 pounds off the car now if you're curious how they got every single proportion right so the kit doesn't look like Lokar no offense to low car love you nolan dodge gave speedcore their cad drawings which allowed them to tool their machines so that each piece is identical in the shape of the factory piece pretty neat but there's actually one piece on this car that's a little different and that is the front bumper and why is it different well because we got twin turbo babies and that's the second part of the speed core recipe increase power now like I mentioned before the regular old demon gets you 840 horsepower with a 6.2 liter supercharged Hemi just a supercharger itself is 2.7 liters now that number is separate from the engine displacement it's the volume of air that's a supercharger can cram into the cylinders each time there's a 360 rotation of the supercharger you get 2.7 liters per Rev that is a ton of air dodge even designed the grabber hood to help feed that supercharger even further it's a biggest scoop inlet on any production car in America and the stock demon it needs all that air and the quarter-mile sprint the demon supercharged v8 sucks in a hundred and seventy-three cubic feet of air that's the equivalent of the lung capacity of 816 humans 816 of y'all just go that's how much air it sucks in that's a lot but why would they ditch their tried-and-true factory supercharger set up for some terms especially because superchargers and turbochargers essentially do the same thing they just go about it in a different way both are forced induction systems meaning they literally force air into your engine more air you can get into the cylinders the more power you'll make the difference between the two is that a supercharger will take its power from the crankshaft meaning you're making the engine work to spin the wheels as well as the supercharger sitting on top of it and that's the biggest disadvantage of a supercharger they actually steal some horsepower from the engine because the crankshaft drives the supercharger as much as 20% of the engines total power can be lost to spinning the superchargers pulley it's called parasitic loss but there's a trade-off you get close to 50% more horsepower with the supercharger and that's why people use them turbochargers on the other hand they're more efficient you see your engine it's already pumping out exhaust gases when it's running in a turbo the freaking love's exhaust gasses it's a Dutch oven and that's what makes a turbo such a beautiful engineering design as your car produces exhaust that exhausts get sent to the turbo or it drives a turbine that turbine spins and then drives a compressor which is just a fancy word for an air pump and all that new fresh air from the air pump is then sent into the engine more air means more power so the speed core team did the unthinkable they took the tried-and-true beloved demon supercharger and they ditched it but they had a good reason really by doing the swap they gained nearly 660 horsepower and with a turbo you don't need to lose power to gain power like a supercharger does turbos are also easier on the engine altogether now could you get a supercharger to give you that much horsepower maybe probably there are some thousand horsepower supercharged demons out there but they don't sound like this speaking of boo screams we got a new boost creeps t-shirt go to donut Mediacom and get yours they're pretty cool speed core team went with two billet twin turbo chargers and then they routed them right in the front bumper if there ever was a factory twin turbo demon this is what it should look like it's super trick even put an oil cooler in here a custom exhaust bigger injectors and a triple fuel pump system when you add more air you have to add more fuel and now the intake is a custom piece built by speed core as well to made up to the turbos and they even retain the use of the factory intercooler not only that they use the factory power chiller because it's chilled the demon comes from the factory with the ability to use the AC to cool down the fluid entering the intercooler even further they call it the power chiller and when it's on you lose the ability to control the AC and the cabin but hey that fluid that's going into the intercooler is much more important so screw your passengers now a speed core team tapped into that system keeping it like it is from the factory that's pretty cool just a quick point you may have seen some articles out there listening this car with various horsepower numbers however I need to point something out in particular now when we talk about horsepower it's important to know what kind of horsepower we're talking about yep there's different kinds of horsepower now horsepower is referring to either wheel horsepower or crank horsepower and what's the difference well crank horsepower is measured at the crank obviously that means they hook the engine up to dyno and a dyno is just a device used to measure force and then horsepower is calculated from that force measurement now in this case all the engine powered accessories like they see compressor the power steering the alternator and sometimes even the water pump are removed from the engine during the test now wheel horsepower on the other hand they have all those bits still attached and you guessed it the cars wheels are driving the dyno so what does all that mean well it means that crank horsepower will always be higher than wheel horsepower for a given car engine combo the drivetrain can't be a hundred percent efficient and transferring power from the crank to the wheels you got to go from the crankshaft to the engine to the trans to the driveshaft to the diff to the axles to the wheels and that's a long route that power has to travel and you lose some ponies throughout all that handoff about 15 to 20 percent so crank horsepower or sometimes called bhp which stands for brake horsepower it's cool but it's wheel horsepower that's a more real number since it's the actual amount of power going to the wheels so this demon has 1500 wheel horsepower 1,800 at the crank again that is absurd for a street-legal car if I had 1,500 horsepower at my disposal think about 1500 horses you got a need like six acres at least yeah more than that yeah I think it's an acre a horse I believe that's the rule you're gonna have one acre per horse so that means you need at least 1500 acre so this right here is the second version of this car and this is the third version of this car a version two of this car ran an eight-six in the quarter-mile about a year ago what's even more impressive is it did so on stock internals and the stock transmission it just goes to show you how good the daemon is from the factory now because it's supercharged dodge engineered heavy-duty components that could handle the added strain on the engine from the added boost but being the speed freaks that they are speed core one and more so in version 3 they swapped in a new demon motor but this time they upgraded the rods the Pistons and a new camshaft it still has the same displacement with the same stock style block and speaking of stock the interior is the same as a regular old demon it still has AC it still has the stereo Bluetooth and nav even left the spare tire in it an 8-second car with the spare tire in the back that is freakin cool thank you guys so much for watching this episode of bumper to bumper we're gonna be focusing on some more engineering aspects of cars got an interesting car out there that you want to know more the engineering aspects behind it and me on instagram at sure my Burren we'll see if we can get it on the show hit us up at donut at donut media click like

Interesting, but not exactly groundbreaking.
Call me impressed when the HEMI moves to aluminum block and 4 valves per cylinder.
