Ram-Air & Boost Tube Upgrade for 6.7L Cummins

00:00 First thing that is 100% noticeable is the turbo. You can hear that baby spool up. It sounds glorious. It’s [Music] [Applause] Welcome back. I’m Alex. We’re at my good friend’s shop once again with his beautiful looking fifth gen Ram 2500 with the 6.7 L Cumins. Last time we

00:26 installed the Banks Monster Ram air intake, which completely eliminates the factory grid heater bolt, possibly rotting off and taking out this engine. It also greatly increases the airflow and thus performance. And well, Christmas came a little bit early because, wouldn’t you know, Bank sent us

00:44 some more performance parts and upgrades for the 6.7 L Cumins. Today we’re installing Banks Ram Air cold air intake as well as our upgraded turbo boost pipes. And with this setup, we’re going to increase our air flow dramatically into this engine. In fact, this aftermarket air intake setup is the

01:02 highest flowing setup there is on the market. And with that, we’re going to gain some throttle response, potentially some fuel economy increase, and potentially some power increases. First, what we’re going to do is we’re going to remove this factory air filter box as

01:18 well as air filter. And I’m going to show you potentially why this factory unit here is going to be limiting some performance out of this engine, especially when we directly compare it to the Banks Ram Air intake. [Music] [Applause] [Music] [Music] [Applause] [Music]

02:00 We got the factory airbox and air filter out of here. Our holsted turbo looking nice right there. And there’s a couple things I want to talk about. So, first of all, this is our stock airbox here. This is injection molded plastic. And so what RAM has done in order to strengthen

02:18 it is we have this meshing or boxing going on. And well, it’s not going to be very advantageous for our air flow as you could you could imagine. Secondly, what’s going on, and I didn’t actually know this. So, in this um this pipe that goes to our turbo, we actually have a

02:36 resonator in here, and that’s to quiet down the turbo noise, but it’s also going to impact our air flow. Let me see if I can get you a better look in here. So, you guys can see there, you got kind of four fins there with holes. That is a resonator. It’s going to help dampen

02:52 sound, but it’s also going to impact our air flow pretty significantly. Thirdly, I think it was time for a air filter change uh on this truck anyways, but this is a stock paper pleated filter. Nothing wrong with these. They work very well, but what can happen is if they get

03:08 wet with lots of rain or heavy snow, specifically up here in Canada, um you can start to see that the dirt and debris kind of makes this um putty sort of film and it can really impact your air flow. Whereas with our new Banks um ram air intake, you can see they’ve used

03:26 higher quality plastics. They don’t need reinforcing, so it makes it a lot smoother in here. Air is going to be able to come in and flow a lot easier. So, upgrading this Bank’s Ram Air cold air intake should have a pretty decent impact on increased air flow. Also, I’m

03:43 very excited to see how this thing sounds now that we’re getting rid of that uh resonator right there. Just before we put our Banks cold air intake on. I’ve removed our turbo pipes. And so this is our hot side here. This is the original Mopar pipe. This is the Banks

03:59 upgraded turbo piping. You can see it’s quite a bit larger. I believe they say it’s about 68% more volume or air flow can flow through this this hot side. And when we say hot side, I mean we’re going from the turbo, the charged air right from the turbo into our intercooler. So

04:17 this is hot air. And our cold air side is over here because our charge air has gone through our intercooler. It’s now cooled and it’s about to enter our engine. So on our cold air side, Mopar actually supplies a plastic pipe, which is fine. I’ve seen it before. This is

04:36 the new Banks pipe. Again, quite a bit larger. It’s actually metal. Um, so we should be able to flow again a lot more air into our engine and ideally make more power. All right, we got our new turbo boost tubes in both sides. Our hot side and our cold side. Not going to

04:53 lie, a little bit of a pain to get everything sort of fitted and and jammed in there, but we got her. Next up, we’re going to put this box in here, get our filter in there, and fire this baby up. Well, we got everything installed. Looks pretty good. We fired the truck up

05:09 earlier. Sounds pretty good as well. I’m going to just finish up here tinkering, put the tools away, and then we’re going to get this thing out on the road and see if I notice any power differences, any better throttle response, and maybe we can hear the turbo just a little bit

05:23 better, which will be kind of cool to see. We got her on the road. First thing that is 100% noticeable is the turbo. You can hear that baby spool up. It sounds glorious. It’s not too loud, but it’s just a perfect whistle. Let me see if you guys can hear it. Listening to what you guys are going to

05:54 hear. You can’t really hear the turbo, unfortunately. Just the cameras didn’t pick it up. But I promise you, it sounded really good. And it does feel a little bit quicker. At least the throttle response is much better than what it was before. Um, I didn’t think there’d be this much

06:12 of a difference in terms of like the feel of power, but I think it’s pretty noticeable to be honest. And, uh, I love the way the turbo sounds. It’s just a perfect little whistle to let you know that you’re driving a turbo diesel, baby. Definitely better. That turbo wine is perfection. I love that.

06:51 Wow. And one thing I do have to mention is that if you do really want to get as much power out of these components that we’ve put on this truck, you’re probably going to want a tune. Um, at least that’s what Banks has told me. And a tune can really take advantage of that

07:07 added air flow. With a stock tune, you’re not necessarily going to see crazy power figure changes, at least on a dyno. To me, on the road, it it feels like we have a little bit more oomph behind it. But that could just be better throttle response. The turbo spooling up

07:23 quicker, giving us the power quicker. We may not actually be building more power if if that makes sense to you guys. But, um, to me, just the noise of that turbo, I don’t know. I’m a little kid at heart. I like a good loud sounding truck. And with the turbo diesel and you can hear

07:41 that whistle, it there’s something just magical about it. And, um, it’s the perfect sound. It’s not overpowering, but it just it lets you know there’s a turbo spooling up under the hood. Well, I’m very happy how Banks Ram Air cold air intake turned out on this truck. I love

08:03 the turbo sound on this thing and well, as well as the upgraded turbo pipes and the monster ram air intake, giving this thing an incredible nice amount of air flow into this engine. So, if my friend eventually does put a tuner on it, he is going to be able to make a ton of power

08:19 with this thing completely opened up. So, if you’re looking to make some nice upgrades to your 6.7 L Cumins, head over to Banks. They got some good stuff over there. If you did like the video, don’t forget to leave that thumbs up. And if you like cool stuff like this, do not

08:33 forget to subscribe. I like doing build stuff on this channel and I’d like to do more of it. So, let me know what you guys think about this kind of stuff. Anyways, enough of me. We’ll see you on the next freaking
