regarding performance ...

The above data results I posted were achieved setting the LC to 2,900 rpm.
But yeah, the Hurricane 3.0L set up in this car is so new that a lot of this is speculation.
But the good news is I encountered zero nosedive, just perfect shifting and strong hard acceleration.

I haven't had a safe opportunity to test mine again yet, but I lowered it to 3000 for next time. I probably should drop it to 2900 too. Do you have the 305 width wheels on yours?

I would find it very surprising to see ANY wheelspin from either the front or rear on dry pavement or a prepped surface.

If I remember right from RacerX's first video mentioning it, he was on a prepped drag strip (albeit a cold one) and I don't think the car was so much slipping, as it was cutting power to prevent slip. Whether it would have slipped or not, the car thought it was going to. So it seems there is some amount of traction control still enabled even when using LC. It's either that or as CareerFirefighter was saying it's likely just a small bit of slip that you don't notice or hear from inside the car over the sound of the engine.

Here is my video from yesterdays 4.40. Unfortunately I forgot to turn the sound back on the dashcam. I need to keep wheel straight lol.

That's a great video from down in Mexico! So glad you had the opportunity to leave the states for a bit to test that!

Ford ecoboost engines respond very well to tuning and there are multiple tuners for them. My tuned MKS ecoboost was a low 12 second car and my tuned Continental was only slightly slower. Both were about 500 pounds lighter than a Charger. Both were FWD biased and the MKS would chirp the front tires on the 1-2 shift but never enough to cause traction control to engage. If the Charger is breaking traction enough to cause the power dip at the shift point, the engineers need to make some changes.

It seems that this issue only happens when using launch control so I am still suspicious that it is related to that rather than traction.

Good point, I didn’t think about them being lighter, just that there’s no way to make the same power in only a tune without something blowing up.

People seem stuck on this only happening in LC and hard launches. The nose dip is reproducible in many other conditions. I’ve had it happen 4 or 5 times in “spirited driving”. Every time it happens I’m like … it feels like you’re manually shifting and hit the rev limiter.

It doesn’t really change my opinion about the car, it’s still fast and fun, seems like a software/tuning thing that could be fixed, IMO.

If this is the case then maybe it would launch better at lower Launch Control RPM settings. This would imply that you would need to build less boost for quicker launch times.

Idk, the solution is probably just drag tires in the front lol

Jeremy Satera stated to run DR's on the back, and maybe summer up front. Heat the rears in Line Lock, put it back in AWD, and let it rip. Go watch his vides about the is car and you'll learn a lot. I have a set of 305/45 MT ET Street R for my current car that I "almost" got rid of.

Nope, base 275's here.

Ditto. Loved my Durango 392. Like this car even better!

Okay, better weather conditions and carrying less fuel, here's more data ...

CONDITIONS
DA: ~1,000 ft
Fuel: 1/2 Tank 93 octane
Added Weight: ~70 lbs tools/etc
Launch Control: Enabled
Launch Control: Set To 2,900 RPM
No Nosedive

RESULTS
...................................DRAGY .............. PERFORMANCE PAGES
0-60 mph .................... 4.15 sec ................................ 4.0 sec .................
0-100 mph ..................................................................... 9.2 sec .................
60 ft .............................. 1.93 sec ................................. 1.77 sec ...............
330 ft ........................... 5.0 sec ......................................................................
1/8 Mile .......... 7.95 sec @ 90.26 mph .................. 7.7 sec ................

THOUGHTS
According to conversion charts, an 7.95 sec. 1/8 mile ET should equal a 12.4 sec. 1/4 mile time.
Better DA and only 1/2 tank fuel netted .07 sec 0-60 mph improvement and a .09 sec reduction in 1/8 mile time and .54 mph increase in trap speed.

You're getting great times for those tires imo

Yeah I have been stalking his tuning channel on Youtube waiting for news on the ECU getting unlocked for tuning. He has a ton of great knowledge but it's hard to sift through since a lot of it is just in his long live-streams.

I gotta say, I'm a little perplexed at people's concerns over traction.
I haven't encountered any wheel spin on the few launches I've done. It just goes.
So other than someone cornering at the limits, I can't see any benefit to the wider tires.

Based on RacerX's videos and what the Dodge tech told him, I believe the assumption is that the car backs off the power when it thinks the front wheels will slip. It sounds like LC has some degree of traction control included. So you won't get any spin, just lose power/time when launching at higher RPMs.
It seems weird to me since typically it is considered good to have just a little bit of slip when launching.

As for wider tires, can't say for sure. The older models definitely benefited from more contact patch. It's possible the increased wheel weight isn't worth it until the car gets more power from a tune.

Yes, it would be interesting to do a side-by-side with two models one having 275 all seasons, and one with the wider summer only tires.
