Dropping A Twin-Turbo Hemi Stroker Into A 2010 Challenger SRT8 - Detroit Muscle S3, E14

Today at Detroit Muscle, we're plugging our highly modified Hemi into a project strafe at the power stop, final challenge, your car given away, but that's not all, we're going to get our hyperventilated with some

Challenger

srt8

to take on the baddest boy on the block, the reigning king of Detroit horsepower is the Challenger Hellcat touting 707 ponies on the crankshaft, these things are no joke, look what I mean in To stand a chance against that monster, we have to create a monster of our own.

We start with a complete suspension rebuild that includes new coil struts along with beefier stabilizer bars. The rear also had to be changed along with a new set of much more. stronger axle shafts and we teamed up with power stop brakes on this car where we got this upgraded set of rotors along with their street and trackpad kits and high performance powder coated calipers. This is the base of our Mopar stray cat that we are giving away. for one of you the ultimate powerstop

challenger

well guys we have our

challenger

back here in the shop and on the lift and with all that suspension work we did a while ago well a lot of his land is here in this Rolly car, but there's a reason we're fixing up a boat with that big shiny piece of metal, well, you guys might remember that we barely got our challenger here in the building down to engine power, well, they took out our Hemi, well, he's back and he's very different from where he started.

The first thing they did was remove the factory engine and we stole our car. Once they took it down, they bathed it in the hot washers, painted it, and then the good stuff started going to a forge. H-beam rods and forged bottom pistons a hydraulic roller cam along with a dual road timing assembly round out the short block new lifters and retainers were put in place the factory headers were CNC ported and then They were hand finished or floated like new A spring pack was installed and they got a custom valve job to go with it, all together they reinstalled our intake with a nice new wrinkle black paint job and some awesome new billet valve covers.

Now Chrysler really did their homework when designing this 6:1. for the

srt8

an example of that is these stainless steel exhaust manifolds they are actually short headers and a lot of guys use them to upgrade 5 7's and while we were at it we went ahead and used some ARP stainless steel hardware while this is available. of the car we will replace some of the wear parts like this tensioner pulley along with the tensioner we got from ContiTech, it is much easier to replace them before installing the engine and induction system and since they don't cost much you might as well do it right now.

This motor mount isn't really bad, but it's looking a little dry, so we're going to go ahead and change it, not to mention give it a lot of power. So we shouldn't take any risks. We have some new mouths from rockauto.com and to change them, unscrew these pedestals, screw the new ones in and put them back in place. The easiest way to install this motor is to be on the front subframe from the bottom up a little bit and lower it from there. The good news is that since this is a factory block with mostly factory dimensions, we don't have to reinvent the wheel to install it now. mark you need to come here and look at this angle think about it 33:35 with everything we have at home we can bolt on the subframe and we're ready to go as we're going to put a lot of power into our srt8 challenger.

One of the things we need to look at is the transmission, now the factory transmission that comes on those SRT eights is really good except when you start adding a lot of power, so we move up to level 10 for one of their bulletproof challenger transmissions . One of the weak links in the factory transmission is the valve body, what will happen is it will leak which will reduce the fluid pressure and eventually cause the clutches to slip. Now when those clutches slip, that creates heat and that heat will destroy this conductive plate, so what level 10 does is completely redesign this valve body with a higher line pressure and install a new conductive plate.

Not only will this valve body not leak, but it will also send more fluid volume to that cooler to keep everything cool and happy, another weak point. Is this input hub assembly? Now what happens is this single crack and that will cause fluid to leak out and cause your clutches to burn out. What the level 10 does is they include an upgraded one that is heat and cold treated, another key component that The upgrade is the clutches, these are the factory organic ones and they are upgraded to this high energy friction material that is heat resistant. . They also include a torque converter that was designed specifically for you depending on your needs and we chose a three and a half inch one. -thousand stalls with multi plate lock now these transmissions are designed to handle 500 horsepower or you can have them build one just for you to handle up to 1200 like the one we have, just another tip, these are good for the magnums and chargers too, so the next thing we're ready to do to our rivals on the flex plate now we went to Summit Racing and they got us a billet unit that will be more than strong enough and to keep it in place we have to sit. of ARP fasteners, we will reduce this torque to 70 foot-pounds and then we can continue to achieve this, much like the engine, this transmission uses a factory style housing that prevents it from needing any modifications to stop it after the break.

turbo

time and then we check out our alley cat competition, whether it's autocross drag racing or an open track, factory wheel studs need a late model upgrade and Pro Touring cars flourish in the days autocross and track but the stock wheel bolts are not made for this type of abuse, we have now seen the factory bolts shear on hard drag launches and fail under heavy cornering loads and that puts you at risk in your car.

Corvette c5 and c6 hubs are used on many hot rods, those Pro Touring cars have aftermarket rear axles that have been upgraded to half inch studs. This kit from ARP allows you to use the same 1/2 inch nuts on all four corners. They also come in two links in case you use wheel spacers or so swapping the drag strip for half inch ARP wheel studs is a smart way to go, if the heat treated 8740 chrome moly has a tensile strength of 200,000 psi, simply ream the hole to half an inch and press in the new studs. As an added benefit if you are switching between street and race tires, the rolled threads and nut starter on these ARP studs make the job much easier.

Hello, we are back with our srt8 freebie and we are getting ready to start installing our power adder, but before we can go too far. On that road we have to prepare the car, which will require that we have removed the front fascia along with the hood to achieve that big power number that we need to beat the Hellcat, we are going to add boost, so we turned to Hellion Power Systems for one of their srt8

twin

turbo kits. Now this is a complete kit that comes with everything you need to install it on your car.

The best part doesn't require any cutting or hacking, of course, the centerpiece of the kit. Now it's the turbos, the base kit comes with twin 61 millimeter units that will give you between 500 and a thousand horsepower, but we decided to upgrade to the 67 millimeter ball bearing units with the fancy billet wheel, one of the things most discouraging that the installation of turbos would have. be the tube, but Helion takes care of all that with all the tubes pre-cut and welded now, they are all stainless steel and have a lifetime warranty to prevent that boost from slipping away.

The kit also comes with a dual 45-millimeter boost driver. The wastegates and this 50 millimeter purge valve, all of these things will allow us to easily exceed the power output of a Hellcat, but it's not just about maximum numbers, as the turbos are driven by the energy produced by exhaust instead of through a belt that reduces your engine's power like a supercharger, can actually improve fuel economy, but let's be honest, who really cares about that? When we're going to do the good stuff, no, these things are going to be good before some of those big cool pieces.

Go on some little pieces we have to go on to make sure this thing works properly one of them we have to change the map sensor another thing we have to change the thermostat to a degree or so a little bit colder and then we have to add This port will be the supply of the oil line for our turbos. One of the things you have to do with this kit is shorten the bolts that are on the manifold flange here, it just leaves a little more room when the turbo comes and mounts. There is no interference up here.

The way Hellion designed this kit is to have the turbos mounted down here under the car. It's a little different than most turbo systems. You see where they are in the engine compartment. The advantage of doing it this way is. The fact that the entire hot side is under the car keeps the heat out of the engine bench, but we had to assemble it on the bench because the way everything fits together so tightly you couldn't assemble it in the car with a ratchet wrench. it's really useful in this situation, there's not much room to plug a plug in, alright guys, the next thing we're ready to do is install our air to air intercooler via Spirito header styles pretty easily, just slide it up.

With a pair of mounts just behind the bumper, this big intercooler is a super important piece and that's why it comes with the Hellion kit. It cools the charge air being sent to the intake cooler, which means, you guessed it, more power to follow. It is the most powerful factory

muscle

car ever built. Take a ride in the Hellcat. We have been involved with the Moe car since the 70's. In fact, we were playing with these cars when they were new. I like the way the cars looked when they were new. they were wooden, they were new, the styling cues and other things on some of the cars are more aggressive than other manufacturers just because of the way they look, the aggressiveness of the styling, especially on a challenger, the lines of the bodywork, the way the grill looks.

It was meaner looking than some of the other cars on the road at the time. With the second coming of the muscle car era, manufacturers began to offer their own modern interpretation of the machines of the 60s and 70s. Ford has the Shelby gt500 Chevy with its Camaro zl1 and Dodge with its Challenger srt8, boy, when they started coming out with the new retro muscle cars, you know, the Camaro and the Mustang and all that, they had some pretty good numbers and we had nothing to run with. Chrysler doesn't It's not like their fight for the third place title for perfection started, so the Challenger came out with the number 8, it entered the market in the highest mode, there is an SRT and not just a normal challenger with a v6 or something like that and they put the highest one. performance variant on the market first they were playing catch up and they knew it, but they did a good job with it.

The biggest problem we had with these cars is that they are heavy but they all suffer from dirt in the 2015 Dodge Challenger. SRT Hellcat was born with 707 horsepower and 650 pound-feet of torque, this road rocket is the most powerful car in history. The first time you get into 700 horsepower is an eye-opening experience. It is a powerful street car that I have driven. It's a car you really have to pay attention to what you're doing when you're driving it or when you're walking away from it. The Detroit boys have outdone themselves. It will go from zero to one hundred miles per hour if I ask you to. "You really can." Don't keep up so this Hellcat can be considered a time machine.

It will take you to a better place in your past. Don't worry, this thing has plenty of horsepower to get you there. Next, we will demystify the plumbing of a twin. turbo system, alright guys, while you were gone we went ahead and mounted all the pipes for our system, which is pretty simple, it mounts to the turbo using a high temperature hose and a couple of clamps. Now there are several of these in the system, but all these tubes. the front routes to our intercooler that come out of the intercooler are more tubes and hoses and such that go to the engine and that's what feeds the throttle body.

Now a key part of this system is this bleed valve and what it does is that every time the turbos are oncoil and the system is pressurized and you release the gas, that pressure has to go somewhere, this little gem will release it so our turbo system is fully connected, it took a lot of tubing and a lot of clamps too for those of you who are at home and may not know all the different types of clamps out there, let's take a look at some Detroit Muscle presents basic tips for the beginner, the first type and definitely the most common are the typical radiator hose clamps.

This is a spring style clamp and you've probably seen them before and probably broken your knuckles trying to remove them. This is a factory style clamp and they hold very well for the radiator hoses, heater hoses. So, many of you have ditched those spring clamps for a worm gear clamp. These are easy to use and can be found anywhere, but they only have so much clamping force when your plumbing is an upgraded application, a regular worm gear style clamp. It works well on really low boost, but if you're jumping to higher boost like we do with our twin turbos, you need a T-bolt style clamp.

The advantage of the T-bolt style clamp is that the surface area is more. wider than a normal one. The style of the worm gear and also the mechanism with which it is fastened is different, the worm gear may fail. You've probably seen it if you've overtightened one of these before and with the tee.style clamp, it's just a bolt and a locknut, so you can tighten it really tight and don't have to worry about the nut backing up when you're talking about applications. with really high boost, for example, like a racing car or if you want. just a really clean look, you can use a locking style clamp like this vibrant performance HD series.

The way this works is you have these ends that you simply solder onto the cold side tube, slide over the collar and lock with the clamp that even comes with a pin keeps it all locked. Another cool thing about these is that once you seal it all up, you don't have to worry about it coming loose and you have about 10 to 15 degrees of movement on each side, but when we talk about exhaust clamps, you need something that not only has clamping strength but also can withstand heat, like this sealed style exhaust clamp. This is really great for normal exhaust systems, but when you go for an upgraded application you need to step up.

For this V-band clamp, it is very similar to a T-bolt style clamp, only here there are flanges that weld to the system and fit into these slots on the clamp. Now this isn't every type of clamp out there but this gives you a pretty good idea as to which one you need for your application and we almost installed our Hellion twin turbo kit today but we still have a few minor things we'll need to address, like the Olan system for the turbos and a little more. of wine, but that's not a big deal now that we still have some improvements we'll have to make to the car to support that big number we're trying to achieve, like the fuel system and the exhaust.

I'll tell you what I do. Trust me, this old car will be a lot of fun to drive. We've been working on our own Dodge Challenger today, but if you have a Hellcat and are looking for a few more horsepower than that supercharged 6-2 Hemi. then you need to take a look at this. This is the Fe Power Momentum GT Cold Air Intake, it is for the 2015-16 Dodge Challenger Hellcat and with 11% more flow it will help you gain up to 37 horsepower and 33 lb-ft. of torque, the kit comes with a lot of nice features, including these really nice T-bolt clamps, a molded math housing, and your choice of a dry or pre-oiled reusable filter.

Well, let's jump from shiny new cars to old and rusty cars. We've all dealt with trying to remove rust from old parts or tools, you name it, here's the safe way to do it, it's non-toxic and will save you a trip to the Evapo Rust Blaster is a biodegradable and reusable rust remover that is a Water based and safe to touch, we have used it to remove rust from several pieces around here and once the piece is soaked you can literally wipe the rust off. This might be a must for that restoration project you're working on, so check it out, it might end up saving you a lot of work, but we're out of time now guys, so keep it in the ditches.
