Performance

[Ram Lover]

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.

Yeah, really all you can do is get some long tube headers and a tune
Perhaps a 6.4 intake if your running the 5.7 (pro tip, maybe tell us what your working on?)

The CAI, larger throttle body, spacers, kinda snake oil on its own


If you really want to go faster about all you can do is get taller gears

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.

The 6.4 air intake is well regarded here as being as good as or superior to aftermarket CAIs. Claims about HP are just that, take them with a grain of salt. There are enough threads on all this stuff, a fair amount of responses will say that the computer will sense the changed feature and adjust the operation so that it gets back to where it wants to operate, negating the benefits sought.

DIYMirage gave some good advice, probably a tune is your best bet but you will be in premium gas all the time. Wouldn't do much else beyond that advice above.

I agree with diy...most of us little 5.7 guys upgrade to your intake manifold. So basic bolt ons for you would be a cold air intake (I'm using AF dynamics from ebay), a set of long tube headers, then get a tune put on it. Our throttle bodies are the same as what's on the SRT's, and you may pick up a few hp from a ported one, you'd just have to decide if it's worth the $400 price tag

The stock throttle body flows just fine until you're pushing a lot more power. @Wild one I think knows how much power you need to be putting down before the throttle body becomes your "bottle neck".

How fast do you need to go a pw is not a race truck

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.

Yes it is!! Everyone around wants to race now. A guy was on my ass tonight trying to get me to race. Not talking just speed, for towing etc.

Ok thanks. Well you saved me some money I guess. I'm still under warranty so not really able to go nuts with stuff.

If you're worried about your warrenty,"Don't" touch it,Stellentis will use any excuse to deny you warrenty these days,no matter what the Magnuson-Moss Warranty Act states.They'll deny you warrenty,then it's up to you to prove they're wrong,and they have some high priced lawyers whose only purpose is to make your life hell

Well I wasn't worried till you said that.

Sometimes using higher octane fuel can provide quite a performance boost. There is one station in the area that sells all they way up to ~98 or something.

On a BMW, you can definitely tell the difference between 91 and 95, but that is because it has a variable cam.

Perhaps look at the ratios in the differentials to see if you are happy with the low end torque vs higher speed potential. Changing tire size is another way to essentially change the differential ratio.

I am kind of into conversion van work, so for me, adding features means stuff like an aux battery pack, inverter, heater, etc.

At the moment, kind of watching and waiting on what happens with the 2025 HD line.

It sounds like you would have been happier with a TRX - not a Power Wagon! Stop trying to turn that Power Wagon into a high-performance machine. Save up your money and wait for the return of the TRX

The Hemi has had variable cam timing of 38 degrees since 2009 ,it's called VVT/variable valve timing,but it's the cam that swings,not the valves. Usually 91 will show a little bit of performance improvement on a stock 5.7,but anything more in octane usually doesn't produce enough of a gain to justify the fuel cost increase.If you're tuned ,it's a whole nother story though

When I put the 35s on my truck I got a phazer programer to change the tire size for the speedometer correction. It has multiple settings including a performance settings it definitely wakes it up but you have to run premium fuel.

Just because someone else wants to race on the street doesn’t mean you have to in Canada if you’re street racing and someone gets hurt the penalty is high. If you want to race go to a track. Maybe it’s because IM old now that I think about those things. A pw is really ment for off-road but you do you i know that when someone calls you out it’s hard not to take them up on it. My wife’s 23 1500 is way faster than my truck but I wouldn’t take it where I take my truck

 

[Tray Burge]

Have you tried adding performance decals, that's where the real performance gains come from?
Seriously, re-gearing is your best performance upgrade.

You have got great advice from Wild and a couple of others.

Want big power and being able to play Ricky Road Race. Go buy a Viper, Hell Cat, Mustang, Vette, AMG Mercedes, Lambo, etc. PUs make LOUSY race vehicles and they are very hard to extract more power from, at least cheaply.

When I want to drive like a Hooligan, it isn't my pickup that I take out.

 

[Ram Lover]

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.
