The Ultimate Trackhawk Build!

What's wrong with everyone? I'm Brenton Brown from Forza Tuning and Performance. First of all, I want to start this video by thanking everyone. We've reached 40,000 subscribers, so we really appreciate the support. We got a lot of positive feedback and that really means a I'm really glad that the videos help people or teach some things so that's basically what they're here for and I just want to say thank you, we appreciate it. Today's video will be about this

trackhawk

, so this is a scenario. for our

trackhawk

, so we get a lot of questions about what a stage is for our trackhawk.

Now the reason we chose this one is because we literally just finished it, we haven't tweaked it or anything yet, but it features a lot of cosmetic things. the exterior that are different and this is like showing you some different things that we can do exterior wise as well as performance stuff as far as performance goes this is a regular stage for our trackhawk

build

so I'm just going to just let's go over that we're going to do a couple of different video series on this truck highlighting different areas that today we're going to cover under the engine, where we're going to do the undercarriage of the truck and then obviously all the exterior elements that you see and explain everything. what's going on here why does this one look different, so I'm going to open the hood, let's check the engine.

I'll explain some things that happen here. This is a 2020 trackhawk. by the way, a couple of small differences, okay, so this standard stage 4r package, the difference between stage 4 and stage 4r is that the r package has all the drivetrain modifications break-in and that's going to be consistent across all of our different performance packages, whether it's whether it's trackhawk hellcat camaro corvette anything, basically late model domestic cars are configured that way, the European side is configured a little bit differently, but for the Well from this conversation we will stay with this, so under the hood, what do we have?

Moving on to stage one is basically in 2018 and going forward we make a safety bypass cable that allows us to read directly into the computer, we modify the pcm so we can modify the original pcm, we can get a secondary pcm and modify it however you want. A lot of people get the secondary pcm and modify it thinking they can plug it back in and the dealer won't know it's been adjusted or whatever it's fake, they can definitely tell another pcm has been installed so we're not going to fool them, so if you spend extra 700 per pcm but that's your goal save the 700 bucks we make fast racing spark plugs on every

build

it has a 160 degree thermostat no it's not too cold maybe if you live.

In Alaska or somewhere, possibly this car runs between 181 and 185 degrees, whether you're in Ohio, Florida, Arizona, Nevada, it doesn't matter. Okay, everything is controlled in the fan settings. The 160 degree thermostat is because we want to make sure the thermostat is fully open. in the temperature range of 181-180 degrees 181-185 degrees, okay, you're using a 180 degree thermostat and you want it to run at 185 um, you run the risk of the thermostat not being fully open, well that's the purpose behind this, we have a lot of questions um we do the bottom pulley um we do the bottom pulley first and I've explained this in other videos um because in my opinion that's the next smartest um as far as financially well, so a weak point in the engine is the crankshaft is not fixed so there is no keyway or anything so these engines are prone to the crankshaft balancer rotating on the crankshaft which can permanently damage the crankshaft which is obviously a very expensive repair so what we do is we go ahead and remove everything and put a In the aftermarket there is a better balancer which is an ati and which is a 10 overdrive pulley that spins the supercharger faster so which increases boost while we are there we fix the crankshaft so it is no longer a failure prone area so you gain a lot of reliability. timing cover to fit the larger pulley and we found out when we looked at the elephant engine when we modified the timing cover it is identical to the timing cover on the hell of an engine and they are exactly the same pulleys and everything In stage three, what we do is then use the exhaust, so we use a custom set of headers made for us by American Racing Header and we use high flow cats to get some extra power depending on where the car is going.

Some states are very strict on emissions so some states allow high flow cats, some states have no emissions testing and some states are very strict so depending on where it is we will modify this part of the package so that be legal and approve emissions. Wherever you live, we do the headers mainly because it's not a huge increase in horsepower, but it gives you a pretty good jump in torque and you're also reducing boost a little bit because you're relieving. pressure in the engine, so now we're running just above the original boost levels and we have about 130 or 140 horsepower above stock at the wheels, okay, basically a pound and a half more boost, which is nothing there is no stress on the engine on a trackhawk we do a couple of different things so on all hellcat based vehicles like the challenger charger we leave the stock catback we don't remove the mid muffler or anything like that and we suggest not making the trackhawk have a suitcase style muffler which is very restrictive and still doesn't sound very good even with the headers and stuff in my opinion so we suggest adding an exhaust cat-back and legitimately adds power in a trackhawk, um, out here in this cold. air intake the same, we only use cold air intakes to make legs and that is the only one we recommend in any of these constructions.

It makes a really nice carbon fiber intake as the tube is carbon fiber rather than metal which means it doesn't get hot. a lot of the metal tubes, even though they are aluminum, if you start the engine, open the hood and touch it with your hand, you can't keep your hand on it as hot, so obviously the air going through a tube super hot metal is not conducive to entering. cold air into the engine um, a cold air leg maker intake will add about 18 wheel horsepower on the trackhawk platform with just the intake, we've tested this numerous times, um, so that's the only brand we recommend , it has a very good quality in terms of the flow characteristics, they start big, they are channeled and you get a great airflow speed.

An impressive design, of course, in stage four, that's the point where we need to upgrade the fuel system components. Well, so that it has different injectors, we make a dual booster pump unit on this. you can get away with not using the booster pump. I just feel like it's safer. I always have extra fuel. I just feel like it's safer to have that extra volume of fuel. Not that you know some people don't like booster pumps. To us specifically. Use Kenny Bell booster pumps only. I think they are very reliable. They are the only ones on the market that I haven't really had any problems with for years and years and it is a much cheaper alternative to using a multi-pump fuel system that you know, if the guy isn't going to surpass this power level , you don't actually need to spend that much money.

The fuel rail design on these Hellcats is a returnless fuel system, so the pump is controlled by a fuel pump control module. Pulseless modulated so you can vary the fuel pump output because it only has one feed going to the rear of the fuel rail on the passenger side so if you're not careful or not used to adjusting these vehicles or something like that. and you're not paying attention to the fuel pressure, what you can do very easily is run the cylinders at the front of the lean rail and basically the injectors furthest from the fuel supply don't get as much fuel so the front cylinders can operate. poor thing, it can damage them.

We have seen engines come from other shops that did not monitor the fuel pressure. If you just look at a wide band reading or the factory wide bands, your air and fuel may not look that bad because the cylinders in the back can compensate for it, that's why we do all that, obviously the supercharger is modified, we've talked about That in several videos, we have adapted and polished the front unit or the muzzle, as it is known, where it actually looks very similar. to the snout you see on the heliphen engine, we go through it and do various internal modifications, we make hard dry pins, we make custom bushings, different bearings, a solid billet hub, we don't suggest changing the supercharger pulley unless you are going to We properly check and update all supercharger components, we have had no supercharger failures and we have been doing this since 2015.

If you go to the forums, you will see supercharger failures and problems one after another, which are caused by spending too much on the supercharger and so. it's from not properly upgrading the internals of the supercharger to handle the extra load, okay so don't do that, don't buy the kit with the top pulley, put it in there, these superchargers are incredibly expensive, no, I don't remember what the one was The price is currently the Hellcat, but I know the Red Eye Demon supercharger costs over twelve thousand dollars, so it's not cheap to fix. We usually use the stock throttle body at the horsepower level we are at.

We don't really see a huge gain in this that you can do, you can actually make a thousand horsepower at the wheels with this stock throttle body without any real problems, and the stock throttle body literally drives a hundred percent like the stock, so you can get in this car and if you don't, move on. you step on the accelerator and feel the extra power, you wouldn't know it's not a stock vehicle when you start swapping throttle bodies, sometimes you get a little bit of drivability, you know, the variations I've covered, our catch can be configured and several other videos, um, we have. many questions we basically sell only the catch cans no we don't the only reason is we find it difficult to keep up with production of just all the car packages we build so at this time we don't sell tuning. the catch can unless the car is being built here and we have no plans in the future, at least in the short term, to sell the catch cans, so unfortunately we don't.

I don't really have a recommendation over all the ones I see on the market. they're these little cans here that basically do nothing, that I personally wouldn't waste money on, I don't think they'll hurt anything, but the benefit will be negligible if anything, so you can watch the other videos and I. Explain in depth how this catch can system works. If everyone has any questions or can't find it, maybe we can make a specific catch can theory and logic. You know the video, so that basically summarizes the under the hood 4r stage that we're going to do.

Another video and we're going to go over all the landing gear stuff that's upgraded, so I'm going to show you some weak areas and some different options that you can do and then you'll see obviously the cosmetic differences between this and a normal one. trackhawk, so I'm going to watch a video and show you all the different things that were done to this trackhawk and so you can just take a look at it, sometimes it's hard. to tell it without another means, side by side, so if you like the look of this, I will explain in detail each different thing that we did, so if you want to customize yours or you know how to change it or you want to know where we are. get some of this stuff, I'll give you all the details on everything you know for your own build, so this sums it up.

If you have any questions that I didn't cover, feel free to leave them in the comments and let us know. We'll try to address them in the comments or make a video or do something to get your questions answered, so again, thank you all for the 40,000 subscriber mark, we're very happy for that big thank you from all the people who watch the videos and they become positive. Your feedback really means a lot to us so thank you and be sure to check out the other videos on this trackhawk.
