550hp and Gauge

[8pack-2]

Well she woke up today fellas … a little over 2,220 miles ~2,255 after trip.

Before today, and I’d look at this almost every day doing a little spirited driving, would always bounce off 390hp line or maybe a hair over. Appears to have hit 520hp or a little over momentarily and multiple times … although I can’t explain the discrepancy between the propulsion view and the gauge view. It must be sampling frequency or unaligned sampling frequency. Either way… highest numbers I’ve ever seen in PP for both and it felt different… UNHINGED. So I do genuinely think the car is making over 100 more HP than it did when I first got it or even yesterday for that matter. I’m now fairly convinced some sort of electronic limiting is going on with the HO engine until some condition is met whether it’s mileage, run time, number of shifts idk .

Cool info!
Just FYI, you don't need to take photos. Put a USB drive in the USB-C ports, then you can take actual screenshots.
Just be aware it might overlay info on them yo don't want to share. But you get a perfect image, no glare!
I edited this one of my Daytona's Performance Pages. It showed my full VIN, Odometer in km for some damned reason, and in the lower right, my EXACT GPS coordinates (i removed the detailing digits)

I’d rather make everyone look at all the dust and smudges j/k.

Yeah I’ve been meaning to get a flash drive for this purpose, just keep forgetting to format one and plug it in.

You should see mine! Well, you could try, but I like to drive windows down when possible, and that screen is DUSTY as hell. You can tell what features I use often, because those parts of the screen are clear.

Good info. My numeric never hit over 400hp but I didn't do the graph. I'll try it. FYI I only have 620 mi on the odo

Yeah, mine was the same way until I hit the miles. I’m guessing it’s just too much power for the trans and transfer case before they get some breakin, so they electronically limit it. What the exact mileage is, idk, but I checked daily with a pull so I wouldn’t worry much until you get over 2,250 miles or so.

So it actually does have reduced Horsepower limitations after all until the computer sees the proper mileage for break in on the odometer.

I'm surprised it doesn't elude to that somewhere in the manual. I gotta put some miles on this puppy!

That’s my conclusion from my N=1 experiment and talking it through with AI. The AI’s rationale was that a greater than 130hp increase over night couldn’t be explained by anything other than some sort of electronic limiter being lifted or some sort of electronically controlled configuration change.

Controls:
-Always used BP 93 octane
-At least one pull every 100 miles with monitoring PP since the manual recommended procedures were done at 500 miles
-ambient temperatures humidity were all relatively similar and never large enough to explain +130hp
-same elevation

I’d love for more people to join in and confirm mileage when they start seeing 500+hp on PP. if we get enough reports we can estimate what’s going on a bit better. I can definitely feel a significant increase in power, not just seeing it on PP. Also, if you look at the previous numbers on my earlier pics the RPMs, torque, and HP just don’t make sense, especially if it’s crank and not wheel.

Too bad we can't find out this unless it's a secret menu.

I was reading somewhere recently that there are some generic "break in" steps that don't compete until around 2000 miles. Some of the seals in the engine can actually take that long to fully set and even without a limiter it can actually give a slight HP increase.

I wonder if our cars have somethig in place to further limit HP until those set? I wish I had saved the chart back when I did pulls at lower milage (at 5k now) I'm not sure if it was the power or the torque hitting 550 when I did it. I didn't look closely.

Mine would hit over 500 on torque pretty much on day one. It was probably torque.

For sure on the seals, but from what I gather that’s usually just around 40 HP relative to the peak output. I’d bounce off 390 like it was a hard limit under WOT before 2,220…. Now it hits over 500hp on moderate acceleration not even close to WOT, so probably a combination of rings and some electronic limiter stuff going on.

They should honestly be more transparent about what’s going on because the scat pack makes R/T numbers until it unlocks and I bet they don’t even limit the R/T because it doesn’t have the extra boost to deal with etc. It feels like a different car the last couple days.

Was this part of the deal you made on your Charger? Later RJD

It was a vip program they had on all new purchases

I tend to think with all the engine technology a lot of this does not apply like years ago. I don't believe that in all the ring set in and such not needed. I will see after 3 years or 36000 miles what takes place. Later RJD

I guess to clarify I'm not trying to say the HP is coming from the engine physically seating/settling/breaking-in, but rather the car having a digital limiter until it thinks everything has settled based around those old assumptions for other engines because 130hp+ definitely feels like too much for that.

That said- I have heard others speculate that at 500 miles it removes a limiter and now again at 2000. I'm a little over 5000 now, picked the car up with 24 miles on the odometer and I never noticed any changes in the power. I drove so gently on the day I crossed 500 miles because I was nervous it was gonna launch me off the road when the limiter lifted (It was January in NY, snow everywhere )
The only thing I have noticed is how the car will try to learn your driving habits. My last gen Charger was the exact same way. If you drove it aggressively for a while it would be begging to downshift, but if you drive it easy for a day then it might be a little less willing to launch at the drop of a hat. I had assumed that was what people were feeling until 8pack-2 showed up with receipts lol

The way the electronics are, there could be a LOT of things we don't know about.

This just happened for me today at 1933 miles. Did a pull 2 days ago around 1850 and only hit 390 hp. Today I tried again and hit 520 hp.

Nice! It feels different IMO. Today I was hitting over 500hp on just highway throttle blips to pass, maybe like 50% throttle. It’s way different behavior since it “unlocked”.

Must be some unknown conditions on how you drive it to get it to “unlock”, but it’s looking like somewhere north of 1,500 and less than 3,000 is the range for that unlock.

My two cents worth is that yep years ago you did break in on engines but now we have the synthetic oils no ring seat. Computer may be doing for other parts of the car. We just need to realize that when they now build engines they are so precise and better machined. Non of the videos I watch mention break in and they are doing drag races and burn outs and do not mentioned they had x miles on the car before trying and got good times in the quarter mile. I think that's interesting. Was the computer holding back? Just some food for thought. Later RJD

A lot of the test cars the YouTubers get likely have a lot of miles on them. Even modern turbo engines still have to ring seat, that’s a fact, but that doesn’t explain 130hp jump.

In a nutshell, electronics are likely holding the car back on purpose until certain, unknown to the public, milestones are hit. It’s probably more so to protect the transfer case and transmission than to do with the engine.

As far as people still drag racing them and having decent times, the car is still fast with 420 hp and 530 torque on tap before unlocking, so I wouldn’t think too much about it, but those test cars generally have already got miles.

We’ve got two people now confirming it and the RHO community was talking about suspicions of it before these new sixpack Chargers existed.
