Does anybody know for a fact if the 2018 Durango SRT has a speed limiter and if yes, what is it?
Thank you

Thanks everyone but I'd still like to know if anyone has a document from Dodge that states the factory setting if any.
I hit 140 very quickly but I was running out of space.
With a K&N CAI and 1/2 tank of gas at 39000 miles. In "Track mode" I ran 0-60 in 3.9 secs. I always run 93 octane and empty the cargo bay. Without any after market tuning.
See the dash post attached.
My Ford Expedition / Edelbrock EForce supercharger at 8.5psi would top out at 152mph. The engine felt like it had more go but even a jet engine couldn't beat the wind resistance and it's a big brick to stop.

I bought a Diablo tuner for my '06 Daytona shortly after I got it. I recall that it was originally factory speed limited to like 149mph, which was the limit of the factory speed-rated tires. Before doing any mods, I remember it easily hitting 140 mph with a lot more to go. I raised the limiter to 195 mph, but like many here have said, even though the Daytona is lower, sleeker and lighter than a Durango, it still is basically a brick, especially the earlier ones. Realistically, I could hit between 160-165, but at those speeds, you run out of horsepower, limited by gearing, and pushing a brick through the air.

With my mods, I was in the 405 - 410 HP range, so even though an SRT has more HP and better gearing with 8 speeds, it sits higher, is way heavier, and is a bigger brick, so about equal. Best realistic guess would be a similar top speed in the 160 - 165 mph range, assuming no limiter.

Don't you love it when you ask a model specific question and get answers that don't apply? :cautious:

As for top speed limiter, I don't believe there is one. Car and Driver lists the SRT as having a 155mph top speed, drag limited, not factory limited.
Hope that helps.
Correct, a simple direct question deserves a simple direct answer. But to each his own.

Not sure I would want to go 160+ in a Durango regardless of the suspension due to the side surface area.
With my SRT10 Ram I hit 160+ and it held its ground pretty good but faster then that, not in a truck/SUV by any means.
