So if it werent for the computer would it go 190MPH. This is why I ask. On the highway my Concorde is turning 2000 RPM's to go 65, at 2500 RPM's I'm at 80, 3000 RPM's 95. If you do the math every 500 RPM's is 15 MPH. So at 6000 that would be 190 MPH. In reality at red line your talking 205 MPH. HOLY ****. So in an ideal situation flat land , no turns or wind what is the potential? I realize there is drag on the car but 160-170 seems feasible. So does Concorde actually mean SST = Super Sonic Transport? Oh it's a 97 with the 3.5L.

Maybe in a vacuum...fact is you'll reach a point where air resistance will keep you from accelerating. Remember, you may have 4000 RPMs to go, but your car can only make so much horsepower. I think it's been said that for a first gen 3.5 the highest attainable speed without a limiter is around 140 mph.

 

[k-nash]

130mph thats about it. Anyway what is with all the threads on outlandish top speed lately?

 

[niwroc]

I was just curious. Don't these 3.5's create decent horse power from 2000-5000RPM? I have no intentions on trying to obtain that speed nor do I wish to. I was just driving all alone and started thinking thats all. After the stories I've heard of steering failures on these cars I'd be quite nervous and was at 95MPH. Did have the car to 118 a few years back and that was a little fast for me and as of now that is my all time land speed record. :icon_eek: I'm not a big thrill seeker but I do enjoy watching others seek theres.

they are probably all the same user.

Nope! I'm totally new here. I'll just sit back and be quiet now. :nosmile:

Drag is exponential, you're thinking in a linear fashion. Horsepower is lost to aerodynamic drag and goes up by 8 times for each time the speed doubles!

here's a formula
HP loss due to Aerodynamic Drag is approximatelyequal to:
Cd * A * (V3, that's velocity cubed!)
--------------
150,000

where:
Cd = drag Coefficient
A = frontal area in sq. ft.
V = Velocity (speed) in MPH

Now these are just numbers I pulled out of the air, but for illustration purposes it still works;

Drag Coefficient (Cd) : .70
Frontal area : 10 sq. ft.
Speed : 100 mph
Calculated HP loss due to aero drag is: 46.7 horsepower.

Drag Coefficient (Cd) : .70
Frontal area : 10 sq. ft.
Speed : 120 mph
Calculated HP loss due to aero drag is: 80.6 horsepower.

As you can see, HP required almost doubles for the fictional vehicle for only a 20 MPH increase. Pretty wild huh?
This is why you'll probably never see a 190 MPH concorde.
Well, unless you strap some JATO rockets to it like Mythbusters did! :shocked:

[gr8crash]

After the stories I've heard of steering failures on these cars

i've only ever heard of one post bout it, and it was a fluke that sumtin just broke, **** happens and it sucked for that person, but i haven't heard of it any other time

 

[Apcsox]

^^ he probably read that anti-chrysler site and took to heart all the **** it spewed

 

[Shadowfax]

lol 190mph, that's stock-car speeds

 

[Great White]

Just so we have a point of reference, here's what 190 mph requires for HP at the wheels for a second gen:

Calculated HP loss due to aero drag is: 316.9 horsepower.
Drag Coefficient (Cd) : 0.29
Frontal area : 23.9 sq. ft.
Speed : 190 mph

Remember, that's at the wheels.
That number would probably also have to be a little higher to account for rolling frictional losses, etc.
Plus, I bet the Intrepid would start to do some serious lifting and have instability issues at that speed. They were never designed to do that kind of speed. Would be pretty scary I bet.

That probably true the car can go at 190 mph. But, in fact, it is impossible. The tranny in 4 gear reduce the engine torque at wheel to much. Personnally I drove my car at 143mph and the engine rev only at 4700 rpm. But man the car doesn't have power to go higher. Just to push this car at 143 mph is not easy. Anyway if you want to make the entire rpm band in 4 gear you need to install the Prowler Pro gear. The max speed with this gear is only 131 mph but the car rev 6000 rpm.

 

[cartmanea]

Peak horsepower in 1st Gen 3.5Ls is at 5800rpm. At 75mph I'm turning 2500rpm, so at peak horsepower speed should be 174mph. At the rev limiter (6500rpm) speed would be 195mph (75*6500/2500). Air resistance would limit it to much less though.

 

[Great White]

Sorry, look above. 316 wheel hp to do 190 mph. thats around 350 at the crank.
Not a chance in the-place-where-it's-really-hot for 195 mph.
Unless you can get around 500 hp out of that 3.5. :smile:

cheers :beerchug:

I have owned 2 different LH cars since 2001.
One 01 Concorde, and one 01 Intrepid RT. Which I still have.
My wife's Concorde steering failed at 170,000 miles. Approx.
I no longer have the Concorde, but kept the Intrepid.
My Intrepid steering failed for the first time about the same mileage.
What happens is the inner tie rod end bushings located behind that hot engine deteriorate over time.
The Intrepid now has 227,000 miles on it and the inner tie rod ends have been done twice.
The rubber dry rots out leaving some serious slack.
I call it the Chrysler LH steering curse.
Hindsight being 20/20 A heat shield between the area where those bushings are (rack and pinion) and the engine woulda been smart.

 

[KxWarrior]

I don't mean to be weird, but...Why would you post that in a speed thread, from almost 14 years ago...? That makes positively no sense.

(Also, most of the time they dry out is true, but in the same breath, the rack starts to leak and the fluid deteriorates the bushings as well, I've not had steering issues as of late but, this is just what I've gathered from all of this.

 

[RickerD]

Lol. That's a good discussion about Concorde speed anyway.
