Well guys, I have to say I have had some disappointing 0-60 times so far with this car.

I have obviously not learned how to launch properly but so far the best I can do is 5.1. I pretty much just shred the tires from 0-40. I have only tried it with launch control @ 1.5k rpm. I heard that I should try without it.

I was just curious how all these people on YouTube are getting mid to low 4s on stock tires.

Some tips would be greatly appreciated.

I am assuming you have a scat or SRT with launch control? Do not know if the new RT have it but you need to find a good road, drop the tire pressure in the rear to around 28 psi, roll out of 1st (Not going WOT) slowly increasing throttle until just before 2nd and then go WOT. If you still get excess wheel spin adjust the roll out throttle position and wait until you hit 2nd to go WOT. Keep adjusting until you have very little wheel spin. Stock tires are just extremely difficult to get good times with. The YouTube vids and magazine writers have done dozens before they hit the numbers they post.

What kinda tires and how good condition are they in? I gained a couple 10th's when I put new Pirellis on my RT - I CANT spin em after the 1st second or so now, I used to could light em up a LOT easier, it's night and day.* I've never bothered deflating the back tires but I know that makes a difference, but I dont know how much. I dont think it matters much for me since I can pretty much just floor it from the go, but it'd definitely help you.

Car warmed up but not hot. Colder weather gives faster runs. Weight reduction where possible - no passengers, gas tank near empty. I basically just floor it as much as I can without breaking the tires loose - traction control off. 5.1 is disappointing for a 392, my 5.7 RT is doing 5.2-5.3 bone stock. 5.6-5.7 in hot weather riding 4-deep so all those variables only account for maybe 1/2 second tops, so I doubt you'll go from 5.1 to low 4's.

Which has me wondering how well tuned your motor is. I'm not a motor guy but maybe you need new plugs or your air/fuel tweaked, clean air filter, or ?

Did you get any tire spin @1500 RPM with the launch control? If not then you might want to try 2000 RPM next. Even with the Goodyear F1 tires I did not have any tire spin @1500 RPM when I tried the launch control.

One other tip, don't put it in sport mode if you are using the launch control. I have reason to believe that when you do so the launch control is aborted, and that means massive tire spin and lots of smoke lol. Either that or I did something else that aborted the launch control!

What altitude are you at?
That's an interesting question, I hadn't considered that. I wonder how much power you lose at high altitudes. Atlanta's about 1000' above sea level and I'm getting about exactly what everyone says 0-60 in an RT is supposed to get. There's no really high altitudes anywhere near here or I'd go experimenting!

My guess is tires, and maybe temperature. Cooler air is better, but not temperatures in the 20s, correct me if I am wrong. I live in PA, not sure where you're at, but I always thought the ice cold winter air dampened performance numbers. I thought prime air temps was the 60s and low 70s.

Anyway, what tires are you running? I was running Michelin Primacy mxm or mxv4s in 245/45r20 and could spin them all day. If I was going 35mph in 1st in autostick and floored it I could fishtail all day. I have cheap Atturo AZ850s in UHP 275/40zr20 and they hook 10x better. If I floor it, instead of spinning the tires, they bite the asphalt and launch the car.

Keep trying different things. I've had my SRT for 7 months and have yet to try the 0-60 and quarter mile timers. Just not my thing I guess.

You start to see drop offs above 3,000 feet. I want to say around 7,000 it's as much as 10% for N/A cars.

Density altitude is a drag racing thing, you can google it. Definitely affects performance.
And the thing with cooler temps is your nice soft tires start to act like hockey pucks.

I have a 2012 Super Bee with the 392 and with stock tires my best 60 on the street was 5.2. This is without launch control and just trying not to burn up the tires. The stock tires are horrible at launching these big beasts. On the track my best 60 was 4.8 and even there I had to be careful not to light up the tires. I have since gotten Nitto 555 G2's in 275/40 in the rear and ran a 4.9 on the street. Can't wait to try them out on the track. The stock tires, road condition, temperature, altitude, etc...they all add up. The magazine writers and youtubers spend tons of time getting perfect launches and finding good road/track.

It's all about throttle control, launch RPM, and tire/tire condition. Add to that things like air temperature, humidity, altitude, etc and you'll be able to figure out what's wrong. It may just be that you're not getting INTO the throttle, but rather mashing it off the line. That = wheel spin which = slower times. If you have cheap or bald tires, that also = the same. Then you have the weather which can heat soak the car and kill power. Try doing it again on a low humidity, say 50F night. Lower the PSI of your rear tires to like high 20s, RPM set at 2K and ride into the throttle quickly but not too quickly.

some RT have the launch control and some don't based on the RT package you select. My 2017 blacktop RT plus didnt come with launch, but came with the "sport" feature. kinda evens out. you can tell the difference when the sport mode is on and when its off.

Well I finally got a time of 4.7....but with traction control on and custom set up basically in track mode with traction on....

Tires still spun and I know this thing can do better

Is the correct method of doing these times to light throttle off the line then stomp on it? I found my acceleration is pretty good using this method. I need to add the performance pages on my '16 R/T but I'm pretty sure I'm getting a good time (5.3s or so) even considering my extra weight because I'm fat. LOL Should I expect 5.1~5.3s with my '16 or can it get 5.0s or faster with a proper launch? Altitude is less than 600ft and the morning temps are still in the mid-50's or low-60's in the AM around here so conditions are good.

I know 0-60 is just bragging rights and all but that metric is important to me. I'd like to see if I can get this Charger faster stock (mid muffler delete) than my old 3000GT VR4 which still is the fastest car I've ever owned at 4.9s 0-60 stock. I'm willing to bet my new Charger is likely going to be faster at everything but 0-20 because AWD > RWD for off-the-line traction. I miss that VR4 sometimes. Such a fast and beautiful car that was.

Like others have asked, what is the temp. outside right now where you live. Im in MN and the pavement is still cold and hard even though daytime temps have been in the high 40s and low 50s. Great for making power but bad for tire hook. Until the temp gets into the 60s it's next to impossible to launch the car.

I'm in northern Texas (just north of Dallas) and the temps right now are mid 50's to high 70's depending on time of day. the concrete doesn't get too cold around here and we had a very mild winter so it should be warm enough for traction.

Oh sorry JCE, I was referring to the OP. I already new you lived in Texas by your Sig.

I used to do a lot of drag racing in the mid 90s and used to bracket race a stick shift SN95 Mustang on street tires. Then I got wise and went for slicks.

The technique for launching on street tires is to hold the car on the converter and then launch smoothly. It's more like squeezing the trigger on a gun as opposed to jerking it (do with that reference what you will!).

For my R/T: 1500 RPM on the converter, let off of the brake, roll on to the gas evenly
For my R/T Scat Pack: 1800 RPM on the converter, let off the brake, roll on to the gas evenly

My launch RPM is almost always the same independent of weather. Where I make my adjustments is with my right foot. On a perfect launch, you should hear the tires chirping slightly as you accelerate. If you don't hear anything after letting go of the brake, it means the right foot needs to be a bit more aggressive. If the tires spin, it means you need to slow down a bit when pressing the loud pedal. If you launch and the nose falls over that means a little more RPM is helpful (provided you're not driving through the converter). On a good launch you should also feel the nose rise as weight is transferred to the rear.

It's a dance and it takes time to get the feel of the car!

With 4.10 gears in my Mustang on all season street tires, I've cut a 1.71 60' which is very respectable.

Now since you mentioned the VR4, I'm also a former Mitsubishi nut! I built a 98 Eclipse GSX (AWD) from a slow 14 second dog into an 11.8 monster with a 2.3 stroker on a small turbo, street tires and pump gas. Hold the e-brake, mash the gas, build 7-8 psi on the stutter box and let it rip. Used to run consistent 1.59 - 1.61 60' times on sticky Falken FK-451s. What a rip! I sold it in 2008 and still miss that car. It was a lot of fun.

Anyway, practice practice practice! And don't hold the car on the converter for more than 4-5 seconds. It increases temps in the trans fluid very quickly. Also allow cool downs in between runs.

Good luck sir!

Same thing here in Michigan. It's frustrating isn't it? Great air and no grip.
