Hey guys. So I am curious to know the top speed of everyone’s challengers. I have a 2017 r/t manual 6 speed and an unlocked pcm. With the stock pcm top speed was 140 before it would shut down. Tonight I wanted to push it a little further and got 160 in 5th gear. It was still steadily climbing but I backed out because my exit was coming up. Are these cars capable of 180+ with stock everything besides and unlocked pcm like mine?

Nice. What all do you have done to yours? Manual or automatic? I feel like these cars will do 180 easily

The highest speed limit around here is 70 MPH so It's possible that I may have topped 80 MPH once or twice.

I'm not sure what highway you are going 160 MPH+ on but I hope the police catch you soon before you kill someone.

Not sure if you heard about this or not but there is a road in Ohio I think(found it, Sun Valley Road Rally. Have no idea where that is.) where they have top speed runs every year. there is one EB that has gone 240+ and several super cars that have gone 225+ there. They have people sit on the banks of the hills above the hiway and some guy with a loudspeaker shouts the speed as they go flying by.
That is a public hiway and that would not be a crime during that time obviously.
Watched the runs on you tube, for the last 2 years. The same car won fasted speed for both of them.
I only have a 5.7 and even governed at 169 I dont think it would hit that speed stock. The computer says the highest speed was 154 but I never had it close to that and at about 150 it pretty much stops excellerating. To get the 180+ you need a lot more than the stock 5.7 has. A scat may come close to that though.

I've had mine 130MPH in a standing mile shifting at 5500 RPM in 5th gear. Early Sunday on deserted interstate is best time to "test".

If you know how to drive and pick your roads wisely you don’t have to worry about killing anyone. It’s not like I’m doing 160 all the time or on crowded highways. And it only took me a little under a mile to get to 160 so also it’s not like I’m swerving in and out of traffic. But thanks for your concern. And I fail to believe you need a lot more than a stock 5.7 to see speeds of 180. Like I said in my original post. My challenger is stock besides the unlocked pcm and I can hit 160 in 5th gear. Still had all of 6th gear left and it was steadily climbing.

Speed is relative, and speeding tickets are just a scam.

If its a dead highway 160 MPH+ is literally harming no one!

I hope the police catch you soon before you decide to go 80mph a third time and kill someone.

Not into top speeds with my Scatpack. Have no idea why someone would want to do 180 - you blow a tire a those speeds and your history. Just not my thing.

From what I remember reading, the 392 equipped Challengers are capable of about 185mph and the 5.7 Challengers are around 170, maybe 175mph. I certainly would discourage anyone from testing that on anything besides a controlled environment with the appropriate safety equipment installed (e.g. roll cage).

I have never seen those speeds in car. I have been on motorcycles and hit speeds in the 150 range, on a track. I must say I would be surprised if a 375hp vehicle could take a 4000+lb vehicle to or over 180mph.

156.4 mph in standing start mile at the Arkansas Mile last year. It was still pulling strong at the mile but I would guess it would take another mile to hit 175-180. Stock 2015 SPS 6M.

I paid for the sanctioned closed course because if you get caught at those speeds you don't get just a ticket. Arrested, most likely charged with reckless driving, car towed, quality time with other miscreants in the holding tank, which may or may not be interesting or painful, and license suspended anywhere from 30 days to a year.

Not too old to wanna go fast, but certainly too old to get caught.

Okay so for all you guys that are against testing your car... why even buy a sports car? Just to go 80 on the highway? I’m not saying we should be going 100+ everywhere we go but some of you are acting like I’m the devil because I want to see what my $40,000 sports car can do. I’m all for driving the speed limits in 95% of my driving but if that’s all you want to do why did you buy a challenger? Mid life crisis? Trying to impress someone? I don’t understand.

No worries mate to each his own. If I had a controlled track and proper safety gear I'd push it all day long. I just know at those speeds if you blow a tire your in deep kaka!
