Headed to get my cat in the am and was wondering the best way to break it in on the drive home. Probably about 300 miles will be open interstate. Suggestions?

Vary the mph and don't go above 4000 rpm if you can help it. Keep it under 55-60mph if you can

Black key will make it easier to keep it under 55. Red or black it's not easy. :)

I'd probably pick some non-interstate roads for the first 300 miles. Slower mph, more stop signs and lights, more variation of rpms and load. Then hit the interstate but keep the load varied.

i had a 350 mile drive home

i kept it at 500 hp since it was raining

i shifted between 6,7,8 every 5 mins or so

i went 55-80mph

i think the biggest thing is just to get the rpms to vary........i dont think the under 55mph is nearly as important

Everybody has there ways, all good for me 250mi so far and I have had the car to 120 a few times and rpms over 5 some times, 60-70 mph and dropping from 6th to 4th and gassing it not quite to the floor yet.

I think the motor needs a bit of slow, med, and some stomping to get use to what your going to put her thru. I wait till 500mi before i let rpms get to 6 for evey gear. That is for later. I broke in my 392 2014 Core the same way, just saying.;)

Just keep he rpms down and vary it a bit. if you have lots of interstate freeway driving, every so often, take one of the exits, drive around in the city for 5-10 minutes too. Stop the car let her idle for 1-2 minutes, then shut it off.
Start her back up in a minute or two and head back to freeway.
Adds a bit of time to the drive, but you are breaking her in, so it's worth it.


On a side note. Supposedly 6200 rpm are the rev limiter, and the peak power is 6000 rpm.
My Hellcat, which doesn't even have 500 miles on her yet, has the redline starting at 5750 on the tach.
What's up with that?
