i know the coupe is aerodynamically capable of 150 mph but the roadster came out after so when the chrysler engineers said it could it could but i dont think they re engineered roadster to do the same they were probably on an island vacationing when the roadster came out and theres no way they would go through the whole process again i dont know if anyone can enlighten me on this subject it would be greatly appreciated.

 

Great question supercrossfire, I'm looking forward to the answer. I hope someone has one. In the mean time why don't you find a stretch of empty hiway and find out?

 

Yes, at about 158 where it seemed a governor or limiter kicked in, I have since had the ECU remapped and understand the limiter was removed!

By the way that was with the top up, I don't know if or what kind of drag the top down would cause so maybe I should..

 

Not a problem. I have been @ 163 with my SRT roadster and 155 with my daughter's SRT. Mine was confirmed with the GPS. I wasn't there very long and this was after LET's ECU tune and after the 181 pulley was installed..

I have been over 150 quite a few times with mine, pre and post tune. Usually done at 6:30- 7am on Sunday morning on the Turnpike (8 lane) on the way to the golf course. Smooth as you can possibly imagine. A bit noisy though. There is a nice stretch where you crest an overpass and can see a fseveral miles ahead. There usually is not any traffic at that time. I am very cautious. Done only when clear of traffic and dry. Tires are new and Z rated Bridgestones.

I think you could basically kiss your a%% goodbye if you hit something on the road or blew a tire.

 

But at least you'd be kissing it with the biggest smile of your life..!

 

Yes, done it with top down.

 

Yes, but only for 1 minute.

 

Why only for 1 minute? did something go over my head again? Is this like the hardon collider?

 

I did my 150 on a stretch of higway that when you get up to speed you have about 3 miles of speed window. So that equates to not much time at that speed but was rock solid. Top down does however gets you all the wind noise that you can expect so don't think too hard about listening to the radio.

 

I had my mom's roadster up to 140mph before the radar detector went off. Sudden deceleration then prevailed. What about noise @ that speed with one of the windblockers top down?

Sorry, bad joke

 

OHMYGOD YES !!

Been there repeatedly!!

Hell ask over a half a dozen crossfires I passed them all at a meet at over 150.

I see that and more at least on average once a week!

Ask around MY top stays down til the rain hurts!

 

Ditto.....been there many times at length....rock solid.

 

YES

 

The roadster can. The question is can the driver do it?

Not a dare, just being specific!


roadster with a stick

 

Valid point, Franc ...

 

Been up to 151 MPH with the top down. GPS verified. No difference between speedo and GPS. Me thinks those German engineers are fussy.

 

Did it today on Interstate 75 along Tampa just for yucks. The car pops to 120 in a snap and another smooth pull to 150+. Damn, so much fun I never did glance at the tach, but as quiet and solid as you'd want. I'll dblck the rpm next time.

 

Are all you people NUTS??!!

Randy, the last time I was on the Fla. T.P. around W. Palm I saw a 6' long alligator along side the highway, I hope they never try crossing the road on a Sunday morning.
And don't you guys have deer down there too?

 

YES I am NUTS !!

DUH!!
