You have the same exact 251 throttle body as the 485 horse SRT 6.4's have,so you're not going to gain much with Matts taper ported throttle body,which only shows at most about 5 to 10 hp "after" you port the intake manifold mouth.The stock mouth is roughly about 82/83 mm,so you have to open up the intake mouth to match his tapered throttle body,your stock airbox flows more then enough air if you install a good filter.
As stated the only thing that's going to gain you any "feel-able" power is a set of long tubes and a custom tune,and after you price out both,you might just decide it's got enough power.
Honestly the best return these days is stick a higher stall torque convertor in it,a 3200 stall convertor still tows pretty decently,and will give you alot more launch power,and can be run on the stock tune.

Thanks for the info instead of the crap I got from others. What filter would you suggest?

I get it to much power still ain’t enough. I bought my pw for the stuff it came with (winch etc). I love my pw it’s got the things that I would have had to add to get the truck I wanted. I still had to build some things that I wanted (rockslides and a topper lift spare tire carrier). Everyone has their own wants and needs myself I don’t need a super fast truck I wanted a truck that I could build into a overland rig. But power is definitely part of the equation.

Thank you! Exactly how I feel. I wanted the off-road capability too like the things you mentioned. I would like to add things too like the molle panels for the bed, tire and gear carrier swing am on the back etc. I think I'm probably just used to the power now and also on 35's recently so with adding all the weight plus towing thought a little more couldn't hurt.

Yeah I put my truck on a diet it gained about 900lbs. It goes plenty fast for me and the roads I travel to go camping on are not conducive to high speed

Exactly. Up North taking the back roads to camp, think she wants to get a camper now, or taking the trailer with the sxs's not for high speed and wanting/ needing the off-road stuff. But the daily driving around here is mostly long highways or interstate where higher speeds are the norm.

 

[4xdad]

For me i live about 50 kms away from the city so I do alot of highway driving. I don’t need more power because more power translates into more fuel consumption and a6.4 burns enough fuel as it is

For over landing / remote camping type use, most people have too small of aux power systems to really support what they want to run.

My suggestion would be to build up a 24 volt power system with ~ 4 kW-hrs of battery capacity and a solid 2 kW inverter.

A fuel heater since you are in Maine for 3 season type use.

A rack or top that you can mount solar panels on the top and at least one side, plus pulling some power while driving from the alternator. Try to reach 400 watts if possible.

Beef up the alternator if it is just a stock 180 amp type, maybe even add a secondary alternator.

DC fridge - lots of them are dual 12 / 24 now.

USB ports - bluesea and others sell dual 12 / 24 volt that can charge modern devices faster than the older 12 volt only type.

Some led light strips, maybe even some under the truck for vision around the truck when it is really dark so people don't trip.

Since you are in Maine, and experience real winters, using Li batteries in the winter is a tough way to go. They only fully function from ~ freezing to ~ 110 F. For most people, I would suggest something like 4 each size 27 or size 31 Lifeline marine type AGMs or equivalent, wired 2S 2P. For better or worse, the combined weight of all of that will weigh ~ 300 lbs total all in, but it will work really well.

Coffee maker, microwave / convection oven and you can be a happy camper.

 

[4xdad]

I have 2 200 watt solar panels on the roof of my truck and 2 12 volt batteries in the bed. If you look at the pictures I posted you can see a red ammo box on the tire carrier inside of it there’s a little diesel heater (works great). The reason I put them on the roof of the truck is because my topper raises up and down. The reason I used regular batteries is because I got them cheap and they work in the cold.

 

[4xdad]

I don’t take any power from my truck because I didn’t want to mess with the electric system of the truck

Ok. I went through 30 of the 78 pages of threads looking for performance stuff. Only found one old one that went the way of the supercharger. I'm probably not going to be doing that, although would be awesome.
I have a 2021 power wagon and I'm really after external bolt on engine stuff, probably won't get into internals, like throttle bodies, air intake, maybe headers. Already have Magnaflow muffler kit. I see a lot of people like Moe's Performance throttle body. Why that one over others? Also S&B air intake. Again why that one? I do like the clear cover with the etched logo but AFE is claiming some good numbers with the momentum intake. And the taboo of questions. Anyone running a tb spacer with their intake and ported throttle body? Thanks.

This AFE Scorcher is only if you have the virtual dashboard. If you have analog speedometer and diameter dials, means you have the older BCM and the Pulsar will be a better choice.

Only one I can share from experience is the AFE scorcher, which I currently run. Leveling kit and 35 inch E rated tires. When I installed them the truck was noticeably sluggish. After installation of the scorcher module performance was a little bit better than stock. yMMV

In my opinion you won't get much "bang for the buck" randomly slapping on a bunch of bolt on stuff. Modern manufacturers are not going to install air takes and exhausts that have lots of restriction.....why, because they are all trying to get as much power and economy out of the engines as possible and putting restrictive components on hurts that. They are not just slapping on stuff that somebody has sitting on the shelf and hoping it works. For example on the air intake. The factory intake is capable of flowing more air then is ever required by the engine. Sure, an aftermarket air intake may flow "more" air but if the engine is already getting all it needs giving it more air doesn't do anything.
Regarding horsepower claims are you really going to notice 10 HP on an engine that already makes 410 HP? Keep in mind that 10 HP is almost always at max RPM, so almost 6,000 RPM. The higher the RPM, the higher the horsepower numbers. Basically that means at 2,000 RPM you may see 1-2 HP, so during initial accel from a stop you almost have not gain.
The last thing I will say is that when you slap several bolt on parts together the power increases are not added together. What I mean is if you bolt on 3 components and each claims 10 HP, you typically won't net an increase of 30 HP.

I wasn't talking about making it a race truck, geez you guys. I was only talking about a little bit more. Others suggest long tubes and tune but I'm making a race truck with an intake and throttle body? Who buys a big V8 but doesn't want horsepower? Why is it a diesel guy trying to do the same thing for way more money it's ok but not a gasser anymore? I'm not going out trying to race I said others are trying to race me at almost every stop light in town and the guy last night I didn't try to race him either I actually slowed down to **** him off.
I got good info from some yes, not all, it's fine the way it is is what I'm hearing. Got it.

Hi there! I have a 2022 PW. I did the S&B intake because I like the looks of it. I also have a cat back exhaust. I like the sound of it. I did these things for a little more HP's and don't care what others think. At the end of the day it is my truck and I will do what I want to it! I suggest you do the same. Oh and post it when you are complete!

I bought a big V8 so I wouldn't have to mess around with it for more power, but I think what most folks are telling you is you'll spend a lot of $$$ for very little power return. If you are looking for ways to justify spending money and/or tinkering, nobody is telling you not to...just setting expectations. There's no low hanging fruit on these trucks for power on the cheap, aside from adding stickers. Stickers, as everyone knows, are 10-15hp each and require no supporting mods.

Remember any filter that flows more air is probably going to flow more dust as well. There's no free lunch here, and if you're actually using it off road do you care more about reliability and longevity or about 2-3 more hp? Awhile back I posted https://www.ramforum.com/threads/engineer-tests-air-filters.213498/ with a video of an engineer with calibrated dust (yes, it's a thing) and a test rig that did a very detailed test of various filters. IMO, it's worth the watch if you're interested in where you personally want to draw the line between free flow and filtering ability.

 

[4xdad]

The reason I bought my k and n filter is because it is reusable and it should last forever. The reason for the cat -back was to get rid of the giant muffler and resonator and to get the good merican rumble

 

[ScubaSteve178]

I did say it's a 2021 power wagon. So the 6.4.
Hmmm snake oil really? Moe's website claims like 12-18 rwhp I think. Other thread said to get that so that's why I mentioned it.

Factory air box and tube flows as well as the aftermarket stuff with the added benefit of already being a “cold air intake”. All the other cold air intakes aside from S&B pull air from the engine compartment, so that’s snake oil for sure.

Jury is out IMO on throttle bodies. I’ve been tempted by Moe’s 87mm TB, but everything I read is that there is no real increase in power, but a noticeable difference in throttle response (which makes sense).

I have ARH long tube headers and Magnaflow cat back with a Hemifever tune, and it really woke up. My 16 has the 6 speed and I run 37’s with 5.13 gears, and the truck is quicker than a 7300lb gas truck has any right to be.

 

[4xdad]

Did you install the headers yourself and how much of a pita was it

 

[ScubaSteve178]

Yes, I installed the headers myself. Install honestly wasn’t that bad, the most difficult part was getting the stupid dipstick tube back into the block. You have to bend the dipstick tube to fit between the headers and can’t mount it back to the same spot, at least not easily, and its a really tight fit to go back in, so the angle has to be juuuuust perfect…at least in my experience. That alone took me an hour and a half…the rest I had done in about 5-6 hours on my own.

 

[4xdad]

No busted exhaust studs?!

 

[Fatbob Frank]

I went with an S&B intake cause I put one on my General and it made a lot of difference.
( 5 or 10 HP makes a big difference on something that only makes 100)
Figured I'd try one on the PW.
I got rid of the muffler and resonator and put on a 12" glasspack about the same time.
Don't know if it makes anymore HP#s but it sure has better throttle response and sounds awesome...
Frankly, better acceleration is all I'm after anyway cause I'm sure I don't use all the HP and torque it made stock.
As far as CAI are concerned I like the S&B because it uses the factory intake scoop and as others have pointed out that's a pretty good design...
It's easy to do a visual inspection of the filter every time I check the oil cause of the big clear window on top.
Easy to pull off the massive cone filter and blow it out every oil change...
If I ever get a new truck ( hopefully never) I'd get another...

I've seen those headers. Think they're a little more than I'd want to spend even though I'm able. Also still under warranty and I think that's more mod than they would approve of if I needed a repair.
I have the digital dash. So the pulsar doesn't play well with that?
