INSTALLED A $30,000 DEMON 170 ENGINE IN MY AWD HELLCAT 300! * 1 0F NONE *

Apr 18, 2024
Yes, I want, guys, we took the

engine

out of the Chrysler. This

engine

was used in a 2020 Jeep Track Hog. If you have been following the build, we will use the oil pan to retain the O Whe Dve system. Since there are some small differences compared to a normal Hellcat or rede oil pan, I also have to change the pickup tube since the track one is different. Once this is done, I will mount the motor back into the base and then continue working. the harness and accessories and hopefully get this working, so now it's time to take the box 170 off the pallet.

The way the book is technically, you have to remove the supercharger and mount these special tabs that will allow you to connect. like a chain or whatever for your chair selector, we've been doing this for years and I'm telling you, after all these changes, we've made a Bel seat or a heavy duty strap will work perfectly and save you a lot. time um so once that's done we're going to change the exhaust manifolds because the 1701

demon

s are too big and we're going to have clearance issues if we decide to use them so we're going to install the trackhawks which should be fine we've seen some trackhawks make 1,000 wheels, 1100 wheels with original exhaust manifold, so that shouldn't be a problem, so once done, you will see us change the exhaust, now that the 170

demon

is out of the I have to replace the oil pan very quick, as well as a pickup pipe, then put the engine back in the base with the transmission, then I will do the exhaust manifolds, so that was my mistake.

I should have checked for oil earlier. I dropped the pan, but I was very surprised because when I bought the hant, it came without oil inside, you had to cover it and break it, so this came with a little oil. I wasn't sure how much. The oil ports were inside, but I had to go to Auto Zone real quick to clean it up a bit and then get back to work. Yeah, I, I, will you, will you, yeah, okay guys, we've got the Demon 170 engine

installed

. In the trackhawk cradle I also replaced the engine with the mounts and we also replaced the exhaust manifolds.

If you can see in the video, the exhaust manifolds on the 170 engine are too big, so the track wants to do the job right. I'm also going to save the old cam motor from hell because it's already sold. Theo will go to Arizona and then we will continue to work hard. There he has the engine

installed

. I did not install the white harness. The white harness. it's right here we have to bring the motor in and install it one more time because we had to relocate these brackets uh before it was somewhere like here so we moved it back about an inch because when we put the core bracket on the core the bracket was hitting this housing for the thermostat and I think I showed it in the last video, so I'll leave it until we lower the engine again, then I installed the harness, these clips here I cut from the flange because These always break, if you guys make these changes, You'll see how they break easily, so I cut them from here and then all I have to do is put a zip tie through that hole and then everything will look nice and clean.

Now it heads the The reason I didn't use demon headers is because, as those on the Trackhawk route can see differently, when we put the demon headers on, they were hitting the Cradle, I don't think there should be any problem when execute them, they are seen. okay but these were very bulky look at that compared to that one oh okay since we had to move the motor back about an inch we also have to redo the transmount and that's what you just saw us do just go back Let's drill two holes now. What we are doing is using the special tool to tell us the angle of the rear differential compared to the transfer case or transmission.
They have to be within the two angles. mark, so if there is anything more than that, you risk breaking the transmission. or break the rear differential as you can see the rear was about 5.4 the front is about 5.8 which is perfect so since we're at those two angles Mark now we need to make some custom spacers so that we can raise the differential. With the nose up on the rear differential, what I have here is a 3 inch spacer, but we're going to cut it in half, about an inch and a half on each side and then it will cover that gap, once it's bolted on.
There, the tip of that differential will go slightly up and give us the perfect measurement we need. Alright guys, so last night we finished the rear end, installed the spacers on the nose of the rear end. It's an exact angle where we need it to be. The only thing we need to do is install the rear driveshaft, but before we do that I wanted to work on the engine harness for the most part, it was Plug and Play, all sensors were compatible. together from the track to the demon 170 motor, but there are a few things I wanted to mention that were pretty interesting to see once I got there, so first up is the AC compressor.
I had to order a new one from the dealer because the trackhawk wasn't going to work the position of the AC lines uh they fit differently than the Trackhawk. Sorry, the charger AC lines are what we are using in the car. The Trackhawk's AC lines are too long. There is no way I can get them to work so we are using charger AC lines so to do that I had to use a charger AC compressor. The only thing I changed was the flexible cable for the AC compressor clutch, which is this thing where I am. Pointing out that the harness we are using comes from a Trackhawk, but the pigtail that goes to the compressor was different, there were only two wires, there was ground and then a positive, which is the white one, so it was very easy, just had than connecting two pins. redo them and that was it, but now I want to show you something that was really good as soon as I get back there.
I finished the AC compressor, as you can see. I installed the accessory strap. I installed the alternator from the trackhawk um that bolts directly to the demon engine um right here you see everything is plugged into all the coils I even put the engine covers on so the whole fuel system is ready so this is what I want to talk about about this plug Here is the fuel pressure sensor for the Demon 170. This connector is the first connector I have seen in this type of style. It has three cables. Now I want to show you the diagram so you know what we're looking at.
This is the diagram for that connector there are three pins, pin number one is a fuel pressure signal, pin number two is sensor ground and pin number three is a 5V supply, this schematic is out of hell 170 right now, if I show you this, this is over. here I'm not sure if you see that plug but this here is the fuel trim quality sensor this is what it tells the demon 170 hey this is how much level of ethanol do we have in this fuel adjust the power level to such and such which It's really cool to see, um obviously the track hog doesn't have, um, it has that, but I was able to find the schematics for it and here it is, there are also three pins, pin number one is the field quality sensor that goes to the pin number. 59 on the C2 connector for the PCM, but the HW track does not have the pin number 59 of the trackhawk C2 being a blank pin, there is nothing there, so what I did was take a pin and connected it to the C2 connector, and?
I'm thinking if I connect it so we have the C2, which is ready, it also needs ground on pin number two so I can ground it anywhere and the ASD relay control is what goes to all the um, all the pigtails for the coils, so I was able to pull a wire from there, so by the time you see this video, I have that connector working. I hope that when we get into the tuning part I can turn that sensor on and the car can adjust the power level according to the fuel level or the quality of the fuel that is in the car.
I know it sounds really confusing, but that's why I've been away for so long. I just wanted to make sure that I'm doing this correctly and if it doesn't work then we'll just adjust it, but if it works then this car will run like a demon 170 runs, which is going to be crazy, so the next thing I want to show you is the plug, Well, that's a plug. for the fuel pressure sensor, this plug here is for the H track fuel pressure sensor which looks like this, literally the same thing, same colors, same three pins, the first pin you have is the fuel pressure signal, the sensor ground is pin number two and then pin number three is an arc of five.
It supplies literally the same thing from the Dem 170 that I just showed you, they just interchange, so this one goes 231 and the other one goes one, two, three, so if you want to color the room color, then that field. The pressure sensor should work with the new flex cable. You're okay, so I finished the hardness of the wi. I have to go outside for a second to pick up the muffler. This is the part that goes into the firewall and keeps the heat out. from the engine bay so the old one was kind of chewed up so I ordered a new one and it just arrived today so once we install this we can put the engine in and it will stay there because the trans tunnel is done and I'll show you how you see that once i get back there okay guys so here it is before we painted the trans tunnel and i forgot to record it afterwards but i'll show you what it looks like once we get the engine.
Back there, but this is the trans tunnel, this is all the space that we needed to make to fit the transfer case, so all this stuff that you see here, this is the bulge that right there is where the transfer case is, now this part. here where you see my mouse is reinforced steel so we use very heavy gauge steel because that's where the driveshaft goes and God forbid if that driveshaft breaks we wanted to make sure it's steel pretty good. it wouldn't go through the floor and hurt someone, so the white stuff you see here is seam sealer, we wait for it to dry, spray it with a base coat and the thing literally looks like an OEM OEM cut and um, I forgot to record . later, but you guys will see once the motor is back in there and how it looks good now, the motor is ready to install.
I have the two pigtails connected, the fuel pressure sensor and the fuel quality sensor, so there is the The fuel pressure sensor was connected and this here is the quality sensor that I told you about, so I did my own pigtail, grounded it, got the BT fire supply and also the ASD control there and so on. I said let's try to control it through the melody and hopefully turn it on so it works, oh heyyyyyy.
