I should recieve Delivery of my Trackhawk this week, and was wondering if anyone has a recommended engine break in method? I'm new to Hemi's and supercharged motors. I know some people argue no special break in methods anymore for late model engines, but I grew up doing the routine on my previous rides.

Much appreciated

Idk if there’s any argument to be had, there’s a break in procedure provided my the manufacturer in the manual. You either follow it or don’t, in the end it’s your vehicle, do whatever you want with it.
I chose to follow the procedure because I’m planning on holding onto this for a while.

FYI, there’s a thread called break in (I think) that has the excerpt from the manual.

Ha the most heated debate since 9mm or 45cal you will get both sides. Me personally ask what is there to brake in? we have roller rockers - the motor has been heat cycled at the factory so pistons are set we can go on and on but the one thing thats way over my head someone brought up was the metal is the gears(rear end). have they been heat cycled? I know if you get gears installed new in a car there is special oil and how long how fast to drive etc and change the oil out in 100 miles. I would like to think thats all done at the factory but no clue?

Building a new motor for a Harley you have to heat cycle it and brake it in slow let the pistons score the cylinders etc of you will be blowing smoke from the oil getting past the pistons.
buying a Harley off the show room floor you just drive it like you want no need for that its already done.
so I assume same with cars? I just drove mine right out of the dealership pretty hard. no track runs but I played with it I have 3000 miles now zero problems?

I think best to just do what makes you feel the best. No right or wrong when it comes to your stuff.

Thanks Hemi, and Rocket. I downloaded the manual in lieu of having the TH yet, and read the break in section. Surprising a bit more detailed then I've seen in other owner's manual. It reads a bit conservative on the Break In, but that's okay with me. Rocket brings up a good point about the variances of what people define as "Break In", and what to do. I've used break in motor oil on a few performance motor builds that the custom motor builders insisted on, and changed/refilled at 30, 100, 200 miles. On the other hand I've listened to experienced knowledgeable engineers explain no break in needed. Just thought I'd ask opinions, and agree that I want to hang on to my TH for years of seat planting joy.

In the past 15 years, I've bought 4 new Vettes and 3 GC's (2 SRT's and now a TH) First 500 miles I took it pretty easy on all of them. No FT starts and I'd try to keep the max RPM's down to under ~4k at all times. Between 500 and 1000 miles, I'd push them a bit more but still no hard launches. After 1000 miles, all bets are off. I have never had any drive train problem and zero oil consumption as long as I kept any of them. My "track times" have been among the best posted for "pure stock" so I have no complaints with these break-ins.

Here's a question to consider about break in periods.

Every wonder why FCA allows launch control to be activated at 500 miles?

IMO that silly button is a gimmick. I can launch just as hard without it from day one with 16 miles on TH.
It is a good question why after 500 miles? I think FCA is saving the idiots from crashing. why wouldnt they limit the RPMs for the first 500 miles? why just launch? does anyone even use that thing more then one time? All that way above my pay grade we can guess but never know.

I am just guessing but US military went to 9mm for capacity is my "guess"

I am following the break in suggested by FCA as well since I plan to keep it. Not just for the motor but for the rest of the moving parts that need to break in like hubs, differentials, transmission, transfer, etc...On the other hand, the last motor I built went in the car and on the Dyno and was broke in doing several back to back pulls at redline. It has held up fine for years since with no issues to report.


I carried a Colt 1911 .45 Cal in Desert Storm. I think we changed to the Beretta 9MM shortly after. There were many reasons for the swap including the increase in capacity and basic load, the ability to share with the rest of our NATO allies and it proved to more reliable in testing. Very soon it will change again.

did you heat cycle the motor or let the rings seat? or just straight to the dyno?

for accuracy I love 1911 or 2011 style I just shoot them so so so much better then glocks or any other guns. Maybe because its STI and Wilson Combats but if the world came to an end and I could only take 1 hand gun it would be my glock lol funny how that is.
I did have the Beretta 92 way back when they first came out I did shoot it good wouldn't mind trying the new ones.

I understand they are staying with a 9mm but switching from Beretta to Sig.

Since the injectors were way bigger than the stock tune would allow it stumbled at idle, but cracked it up a few times getting it all buttoned up, checking for leaks, oil pressure, loading on the trailer etc... It also had most parameters changed after data logging it and doing a cold start. I guess that could be called a few heat cycles.


I never liked the Beretta, just as a back up maybe. It isn't modular for most units' diverse needs. I was always lucky to have units that purchased better handguns and the new Sig sounds like a good choice. There are gonna be a lot of slightly used Berettas for sale soon.

I've shot a number of 9mm's including target model Glocks, and only half liked my Steyr GB which has a gas blowback action which I still own. That said, none of them compare to a .45 neither in terms of accuracy, or stopping power.

I'm old school and just did a normal break in taking it easy for the first 1K miles. Low RPMs but not constant, for the first 500 and vary RPMs up to red line and drive it normally as you should with a performance vehicle. So far no oil use which is always the goal at 17K miles. I have carried and fired the 1911, 92 and have a P320. Really like the SIG for shooting and carry and was pleasantly surprised when Army picked it to replace the big Beretta. 9mm will not have the take down of the 45 but all were good firearms. Anytime you get to shoot is a good day especially if getting to the range and back in the TH is included.

jimvanpatten:

I did the same break-in procedure as you did. I also have had virtually zero oil use (now at 10k miles.) In fact, my TH has had zero problems anywhere (knock on wood...or carbon fiber trim.)

The sheer fact that the 1911 is now over 100 years old and we are still considering it one of the best sidearms says a lot.
I always enjoy shooting it.

During the first 500 miles, Launch Mode will not function so no need to try that. I didn’t do any full throttle acceleration the first 500 miles.

Ran the factory oil until 5,000 miles. My TH used a little oil the first 2,000 miles but tight from that point forward.

I have 13,000 miles on it. Using Mobil 1 synthetic 0w - 40.

Have fun!
