I have a Renntech ECU & pulley kit tuned at 93 octane. I personally talked to the tuners at the main Renntech store in FL. to make sure I was getting all I could out of the car and still keep it a safe tune.

I really don't know exactly what kind of HP she putting out, I went ahead and put in some K&N's that should add a little more. When I talked to Jeff who is the main ECU tuner at the FL. store he said he would do it up right and that I would be amazed at the difference. He was right, I don't think I've ever been in a car running 90 MPH, floor it and pin you back in the seat like this thing will. I'm just guessing, but I'd say it's putting out between 385 to 400 HP at the flywheel, somebody mentioned in this thread that it wouldn't do 200 MPH, I would just about put money on that it will.

 

It is fun for sure!
I've had mine to 170 mph now (previous best was 165 mph) and it was still pulling pretty good when I let off.
Like Steve said, you can mash the gas at 100 mph and it will pin you in the seat, this car is just a rocket from 100 mph to 150+ mph!

 

wow, you mean all the talk, and the 200 mph speedometer and it won't go over 151. i've had my ltd roadster to over 135 with room to go, i'm truly disappointed. is the ltd regulated too? i know the chrysler website showed tommy kendall driving the ltd at over 150 mph on the autobahn. i guess you never stop learning.

 

Sounds like a trip to the salt flats is in order.

 

The limiter is actually set at 158 mph...had mine up there before and mine is stock.

Did you happen to notice where your tach was at 170 MPH, at 172 mine was at 5,600?

 

I have a limited not a srt just wanted to put in some more info.
The limited has a taller gear (3.27?) than the srt (3.06). The taller gear will also limit the top end of the limited.
I have a gps system in my car. At 140 mph the gps and speedo are only 1 mph off.
This obviously doesn't give you guys the info you are looking for but the more pieces to the puzzle the better.

I actually have no need to do 151 mph I wish I could get a 3.55 or so gear to help the 60 foot and 0-60 mph times.

 

I'm with Stryfox, here in Ohio I sincerely believe the Highway Patrol can legally "shoot first and ticket later" if you tried to make any of those high speed runs on their highways. I think that's why they have "TARGET ENFORCEMENT" signs posted all over the place.
Anyway, I wish the Crossfire came with a 3:73 gear, I think it would really wake up the automatic Crossfire's at the lower speeds where most people usually drive. I wouldn't be surprised to see mid to low 14's in the 1/4 mile.
Unfortunately it wouldn't be that great for a 6 speed, since it would make 1st. gear practically worthless.

 

Actually that taller gear you're talking about would give you a higher top end, you will have more revolutions of output from the rear-end than the 3.06 with the same input to the rear-end. As for the high speeds, that's something I don't do on a regular basis, I will only do that at certain times of the day, (early morning) and when there is no other traffic.

 

If you replace 3.06 or 3.27 with a 3.55 or 3.73 you will gain bottom end and lose top end.
This I am sure of this.
With the taller gear you will run out of rpm on the top end.

 

Yes, I agree, I must have misunderstood your previous statement.
