that has twin turbos, this demon not only ditched its infamous supercharger but it also has the full carbon fiber body treatment and we are not talking about a cheap, second-hand car. factory carbon fiber, we are talking about top space grade for your stuff, that's right, there are different types of carbon fiber and we are going to talk about it now. The engineering behind the original wheelie-producing demon was already impressive, but this one is even better. and today I'm going to show you why, so let's jump in and take a look at the

demon, aka now, if you notice I'm not in the typical bumper-to-bumper studio environment, well, that's because we.

We're doing our part here at Donut by not leaving home, so we thank you for seeing all four of us. Matt will look a little different, but we'll still give you some cool videos with some insight and a lot of laughs. Dodge dropped its third-generation challenger. Back in 2008 and every year or so since then they've been releasing improved, faster versions of their Mopar-inspired muscle car, making the GT n RT the pet bow and even having an all-wheel drive version in 2015. It's gone crazy and released the Hellcat, a 707-horsepower challenger, and then in 2018, they lost their minds and built the demon, an eight-hundred-and-forty-horsepower street-legal weird car.

It was the fastest non-electric car to reach 60 miles per hour. from a standstill and the fastest to do a quarter mile and the first production car to do a damn wheelie dodj had built the most absurd challenger ever to the speed pork and these guys are now in the business of making carbon fiber super pleasant. parts and build high performance vehicles, they always use the same very complex recipe, reduce weight, increase horsepower, you can literally see those are the two areas they focused on when building this car, all fiber body of carbon and give the engine more power, that is the supercharger, eliminate. twin turbo setup so those are the two things I'm going to focus on today let's start with the first part of your recipe and that is reducing weight by using carbon fiber everyone knows carbon fiber is cool super It's light, it's strong, it's Purdy but it's also expensive.

So it's impressive that the body panels of this car, the bumpers, the hood, the roof, the fenders, the doors, the splitter, everything is made of carbon fiber and by making all those parts with carbon fiber , the demon is six hundred pounds lighter than the original body, that is, 15%. losing weight from a common 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 in the scene drag and that's it, for every hundred pounds you lose, you also lose a tenth of your quarter mile time.

That general rule disappears as your car gets faster, but the fundamental principle remains the same and that means less weight equals faster times at the drag strip, so losing weight. Using carbon fiber is a go-to method for shedding pounds, but what exactly is carbon fiber? Now you hear it used 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 it. from a guy called 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, you have electricity that heats a thin strip of material called a filament, the net filament glows Well, Edison used cotton threads and bamboo slivers as material for his filaments after giving them the size he wanted, he even baked them and when you bake those materials, you are basically carbonizing that material, which means you are making a carbon copy of that. cotton thread he was the first man to invent carbon fiber a carbon fiber is made up of very thin strands of the element carbon just a bunch of carbon atoms joined together to form a long chain now these long chains are extremely rigid strong and have 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 you weave the yarn to make a cloth or a sheet and this is the raw building material Used to make carbon fiber parts, even the way the carbon fiber strands are intertwined can vary to give different appearances and alter their strength properties.

This is the front fender of my RC 51, my motorcycle, and it uses a standard checkerboard pattern. You can tell it's a chessboard because it looks like a damn chessboard, so how do you go from taking carbon fiber sheets to carbon fiber composite parts like this? And that word compound is the second part of the equation and it's an important part that you usually get. When we talk about carbon fiber parts, we say carbon fiber, but what we really mean is that the carbon fiber composite that you see on its own is quite fragile and can break, crack and split quite easily, so which is suspended in a glue-like material.

It is called epoxy resin before it is molded into a piece like this. 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. Slightly plastic in nature, which is good because it helps absorb strong hits like a crash without creating damaging splits between the carbon fibers, so that's the cool carbon fiber, which makes Speed ​​​​carbon fiber ​Quartz is so unique. Remember we talked about that epoxy resin two seconds ago. but there are 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 force all the resin into the fibers and then let it cure.

When it's ready, it comes out of the mold looking shiny like this. Now the most time consuming and tightly controlled way to apply resin is of course what speedcore does and that is to use a process called dry or prepreg carbon fiber and instead of coating the carbon fiber fabric by pouring resin on it, the dried carbon fiber has the resin coated on the fiber fabric, each strand has the proper amount of epoxy while manufactured, it is prepreg now the fiber to resin ratio is controlled throughout the process. The prepreg carbon fiber is molded and placed in an autoclave where it is cured, so an autoclave is just a pressurized oven, kind of like a pressure cooker.

They use this because putting the piece under high pressure and heat fixes any irregularities the piece 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, now it's the wet process, even when vacuum sealed you end up with a excessive amount of resin and that extra resin is On the other hand, the extra weight costs a lot more to make parts with prepreg when you go to flea bay and look at the carbon fiber parts coming from China, 99% of the time they will be the wet variety and even then, the residents. it's just painted and not even vacuum sealed, they just heat it and cure it and that's not much quality control, they also make it cheaper by only using a single layer of carbon fiber and then backing it with fiberglass on the fender of my RC 51, that's what they did and I know it because I can look inside the piece and I can see that the fiberglass is opaque so you can literally see the light go through the carbon fiber and they try to hide it by spraying this . black section, but I'm not a fool and now you're not a fool because now you'll know that someone is sending you a piece of fake carbon fiber.

This is a good way to check. Hold it up to the light and you will see light through it. They try to paint it and hide it, if they did, they were grouped together. Okay, they went way off script. I'm sorry, but whether they speak or not, they spared. They use the best of the best when building their daemon. It takes them around 200 hours. to do a complete body panel swap by hell, every piece is hand made right here in the good old USA. Am I taking every fender and bumper panel and replacing them with their own carbon fiber piece? ?

Now drop another 600 pounds off the car if you're curious how they got each ratio right so the kit didn't look like Lokar. No offense to the low car. I love you. Nolan Dodge gave Speedcore his CAD drawings that allowed them to equip their machines so that every part has the same shape. The factory part is pretty good but there is actually one part on this car that is a little different and that is the front bumper and why is it different? Well, because we have twin turbo babies and that's the second part of the speed core recipe for increased power now.

I mentioned before that the regular old demon gives you 840 horsepower with a 6.2 liter supercharged Hemi, only a supercharger itself is 2.7 liters, now that number is separate from the engine displacement, it's the volume of air a supercharger can squeeze into the cylinders every time there is a With a 360-degree rotation of the supercharger, you get 2.7 liters per revolution, which is a ton of air. Dodge even designed the hood to help feed the supercharger even more. It's the largest air intake on any American production car, and the original Demon needs all that air. and in the quarter-mile sprint, the supercharged V8 demon sucks in one hundred and seventy-three cubic feet of air, which is the equivalent of the lung capacity of 816 humans. 816 of you just go, that's how much air it sucks in, that's a lot, but why would you abandon your tried and true factory supercharger set up for some terms, especially since superchargers and turbochargers essentially do the same thing, only Do they do it in a different way?

Both are forced induction systems, meaning they literally force more air into the engine. The more air you can get into the cylinders, the more power you'll make the difference between the two: A supercharger will take its power from the crankshaft, which means you're running the engine to spin the wheels, as well as the supercharger in the top. of this and that is the biggest disadvantage of a supercharger: they actually steal some horsepower from the engine because the crankshaft drives the supercharger up to 20% of the total engine power can be lost by spinning the supercharger pulley. It's called parasitic loss, but there is a trade-off. -off, you get about 50% more horsepower with the supercharger and that's why people use turbochargers, on the other hand, they are more efficient.

You see that your engine is already pumping exhaust gases when it is running on turbo. The damned exhaust gases of love. It is a dutch oven and that is what makes a turbo such a beautifully engineered design as your car produces exhaust gases which the exhaust gases are sent to the turbo or drives a turbine which spins and then drives a compressor, which is just a fancy word for an air pump. and all that fresh new air from the air pump is then sent to the engine. More air means more power, so the team at Speed ​​Core did the unthinkable: they took the tried and true demon supercharger and abandoned it, but they had good reason.

Actually making the change they gained almost 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 now, could you get a supercharger that would give you that much horsepower maybe? There are probably thousands of supercharged demons out there, but they don't sound like this talking about booing. We have a new Boost Creeps t-shirt. Go to Donut Mediacom and get yours. They are great. The Speed ​​Core team chose two billets. twin turbo chargers and then they put them right on the front bumper, if ever there was a factory twin turbo demon, this is what it should look like, it's a super trick, they 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 velocity core and also for the turbos and they even retain the use of the factory intercooler not only do they use the factory power cooler.

Because it is cold, the Demon comes from the factory with the ability to use the air conditioning to further cool thefluid going into the intercooler, they call it an electric cooler and when it's on you lose the ability to control the air conditioning and cabin, but hey, that fluid going into the intercooler is much more important, so to hell with your passengers now , a core speed team took advantage of that system to keep it like it was factory, that's pretty good, just a quick point, you may have seen a few articles listening to this car. various numbers of horsepower, however, I need to point out something in particular now that when we talk about horsepower, it is important to know what type of horsepower we are talking about, yes there are different types of horsepower, now the horsepower of power refer to wheel horsepower or crank horsepower and which one it is.

The difference, well the crankshaft horsepower is measured at the crank obviously that means they connect the engine to the dyno and a dyno is just a device that is used to measure the force and then the Horsepower is calculated from that force measurement. Now in this case all the accessories driven by the engine as you see the compressor, power steering, alternator and sometimes even the water pump are removed from the engine during the test, now the horsepower The wheels, on the other hand, still have all those parts connected and you guessed it, the car's wheels are driving the dyno, so what does it do? all of that is well-intentioned, it means that crankshaft power will always be greater than wheel power for a given combination of car engines, the transmission cannot be one hundred percent efficient and by transferring power from the crank to the wheels, you have It has to go from the crankshaft to the engine, to the transmission, to the driveshaft, to the differential, to the axles, to the wheels, and that is a long route that the power has to travel and some horses are lost along the way. that pass-through is about 15 to 20 percent, so cranking power or sometimes it's called bhp, which means brake power, is great, but wheel horsepower is a more realistic number, since that's the actual amount of power going to the wheels, so this demon has 1500 horsepower at the wheels, 1800 at the crank again, that's absurd for a street legal car, if it had 1,500 horsepower of power at my disposal, think 1,500 horses, you need like six acres at least, yeah, more than that, yeah, I think it's one acre per horse, I think that's the rule. you're going to have one acre per horse, that means you need at least 1500 acres, so this here is the second version of this car and this is the third version of this car, a version two of this car ran eight-six in The quarter mile about a year ago, what's even more impressive is that it did it on the original internals and the original transmission.

Just goes to show you how good the factory demon is now because it's supercharged with heavy duty Dodge designed components that could handle it. the extra strain on the engine due to the extra boost but being speed freaks they are the core of speed and more in version 3 they changed a new demon engine but this time they updated the connecting rods, pistons and a new camshaft that still has. same displacement with the same stock style block and speaking of stock the interior is the same as a regular old demon, still has air conditioning, still has the bluetooth stereo and nav, even left the spare tire on it , an 8 second car with the spare tire on the back that is incredibly cool thank you all so much for watching this episode bumper to bumper we will focus on some more engineering aspects of the cars.

We have an interesting car out there and you guys want to know more about the engineering aspects behind it. that and me on Instagram, I'm sure my Burren we'll see if we can get it on the show, hit us up at donut at donut media, like, subscribe, thank you all so much for watching, bye for now.
