Duramax Monster-Ram Review
In one of his video entries, The Duramax Monster‑Ram Review by DMAX enthusiast Rocky Rohde talks about the performance difference between the stock turbo compressor inlet and the Banks Monster-Ram for his 2024 Duramax. Aside from the size difference, which eliminates any restrictions and improves the inlet’s mass airflow, the Monster-Ram incorporates a proprietary design that reduces pressure loss by 18.67% at the compressor inlet, resulting in an impressive 6.01 lb/min gain in mass airflow over stock. “The difference is in this is when you let out of the throttle and you the get back into it the stock one is going to give you a delay, because it’s going to push that air back in the turbo, then the turbo then has to respool up. If you let out with the Monster-Ram it’s going to deflect that air back into the inlet of the turbo and keep it spooled. Quicker, faster, better.”

There’s a quick recommendation of the MAP Sensor Relocation Kit in Rocky’s video. While there is no performance gain, by moving the sensors out of the flow of the recirculated, oily, and soot-loaded exhaust flow in the intake manifold, the spacers will keep your MAP sensors cleaner. Clean MAP sensors help your truck achieve better fuel economy and maintain peak performance. Rocky’s truck had only 2,500 miles on it, and the carbon buildup on the sensors was already apparent. Installing the MAP spacers will definitely make a difference.

During his test drive of the truck, the improvements from the Monster-Ram are immediately noticeable. “I can definitely tell the difference,” said Rocky. “On the low-end pickup, just from a start, it seems to have a bit more pep. Where it really shines is on the shifts, just like I talked about. This thing is now steadier through those shifts with more steady power. I absolutely love it on my truck! If I were buying another truck tomorrow, this would be one of the first things that I would order.”

00:01 all right y’all thanks for tuning the video today today we have the banks monster ram turbo inlet got 2024 Denali durmax diesel behind me check the website make sure you get the pr part number I’m going to put a link up for this one so it’ll be correct and what we’re going to talk about today is the
00:15 difference between these two pieces what’s the benefit okay the benefit you know with banks always is going to be a little bit bigger if you look you can put this inside the banks one right so the banks diameter is a little bit bigger but the details really come from
00:30 this lid and the way it’s designed with the anti surge on the turbo okay I’m going to put some video I mean some photos up and show you the difference on how the anti surge Works versus this one versus that one so this is the stock tube you can see that any pressure that comes back
00:47 out of the turbo is allowed to go back into the inlet without deflecting it this is the banks turbo inlet and you can see that it deflects the air back into the inlet of the turbo which keeps it spooled up and then so anybody say what is Turbo surge right so if you go
01:03 look at a Dyno of a diesel truck and you watch it basically your turbo spools up and when the load changes or you know let’s go first to second shift or the third shift you’re going to see the dyno and what it’s going to do is it’s going to spit back into the intake right and
01:19 you’ll hear it in a lot of those dinos and what it does when it does that it blows hot air back up in the turbo and it almost pulls the compressor wheel to half speed or almost stop by pushing the air back out okay what you want to do and this is what banks this is why they
01:35 Design This is it’s the way it def Flex the air back into the turbo so if you have a push back of air coming back into here it deflects it back into the turbo to keep your turbo spooled up so the difference is in this is when you let out of the throttle and you go back in
01:51 this is going to give you a delay because it’s going to push that air back in the turbo Turbo’s got to reschool up if you let out with this one it’s going to deflect that air back into the inlet of the turbo and keep it spooled quicker faster better response so let’s get to
02:07 the install real quick I’ve already got it tore apart because I wanted to show you both pieces but uh let me get the camera we’ll take a look and see what we need to do okay y’all Banks is a really good video on installing this if you want to watch it go for it um you know two
02:21 options you can either do it without removing the compressor or remove the compressor from me you know dropping those bolts Down The Galley looked a little risky I was like you know what I’m going to pull the belt just take the compressor off took about another 5 10
02:33 minutes um you are going to need this is a basically a 13 mm it’s a/4 in Drive wobble and this is how you will get it out if you don’t want to pull the compressor but uh for me it was just easier so I pulled the compressor but we’ll turn this around real quick and
02:49 I’ll show you what I did so I’ve got a rag in the turbo just to make sure I don’t get anything in there while I’m getting all this ready um but if you look back here this Bolt’s going to give you a little bit of a hard time later so if you’ve got the compressor off you
02:59 want to go aad and and just cut it there’s no reason that stud needs to be there um that’ll make it easier and uh anyway you just pull the belt get the compressor up just unplug a few harnesses and uh there’s two bolts on there and um I’ll drop in the piece right now about how to stuff a towel
03:14 under it to make sure you don’t drop that other bolt okay so I’ve got all the Plastics removed you can see that one of the things I wanted to show y’all is what you’re going to use to remove that bolt is right here it’s a 13 mm it’s a wobble but one of the things to
03:31 do just kind of make sure if you’re not removing the air compressor or if you are is you find one of your wife’s best dish towels that you can find in the kitchen and you’re going to go ahead and shove it down there and get it under because if you drop that bolt you want
03:44 to be able to recover it and as you can see I’ve got that towel tucked in there so it’s going to protect me if I drop that bolt I can get my magnet and just grab it if it falls down in that intake chances are very slim you’re going to get it back out so I’m going to do this
03:58 side and then I’m going to move to the other side and Tuck the towel under it and do the same thing and get this neck removed okay so as you can see we got the bolt loose we got the towel down there it’s got nowhere to go get our magnet right and straight out with it
04:15 now we just got to do the same thing we’re going to tuck the towel under the other side get it loose and uh get it removed also okay so one trick is once you get that uh turbo inlet in there um old school mechanic trick this is just out of the gasket it’s just a piece of the
04:28 paper what I do is I’ll take that put that in there these new bolts take a 10 mm socket you can push that on there and you’re good to go so that way you don’t have to worry about dropping that bolt we get it put in okay so this is what I wanted to show y’all Y can see the anti surge built
04:45 into the Turbo from the flange there’s a little bit hole where that stuff comes back to the intake it’s actually under the lip of this and you can see how it deflex it back into the turbo when it comes outside of that ring okay so the next part number I have for you is the 64410 it’s the manifold air
05:04 pressure uh spacer kit this is exactly what it looks like just need to make sure your O-rings in there all it does is take it out and it gets it out of the flow of carbon right it’s just sensing manifold air pressure so it’s going to get it out of that direct flow and it’s
05:18 going to put it up here um so anyway what we’re going to do is pull that 10 mm bolt out pull that out the sensor will mount to the back of this and then this screws down with the bolt and the Allen wrench supplies okay so this truck literally has about 2500 mil on it how carboned up
05:34 do you think this is going to be look at that already for500 miles and that’s going to be your finished install all right y’all so first impression driving on the highway I got this thing installed and I can definitely tell the difference it on the lowend pickup just from a start um it
05:59 seems to have a little bit more pet and then where it really shines is on the shifts just like I talked about the beginning of the video man it doesn’t like you know you kind of had feel that little slou right in a shift and then it would kind of pick back up as this thing
06:12 is just steady through those shifts with a more steady power so you if you don’t understand turbo surge man research it check into this part it’s really worth it absolutely love it on this truck if I was buying another truck tomorrow be one of the first things I order so anyway
06:30 I’ll put a link to it right here if you want to purchase it you get 10% on the bank’s website use Rocky for the code you get a 10% discount also on anything you purchase on the bank site so go there check it out thanks for watching the video if you like it please hit that like please hit
