I was playing with a 350Z on the highway and the SRT nosed over and quit accelerating. It simply quit pulling and held a constant speed despite my foot being mashed to the floor.

Stinkin speed limiter.

The little Z was quicker than most I've played with but I didn't have too much trouble going around him. The last time I let him get a little speed up and ran him down. He seemed to quit pulling just north of 140 mph. I went around him and managed to find the limiter at 158 mph. What a spoil sport that is.

BTW... we were being stupid but at least it was on a desolate stretch of highway.

 

And you still want to get rid of your car??? Build a garden shed to put it in and KEEP IT!! I didn't realize how small a piece of real estate the Crossfire covers 'till I put mine into the garage - and still had room for my bike and quad behind it!
BTW...do the aftermarket computer remaps eliminate that little top speed irritation??

 

It is impossible to eliminate top speed limitation, but they set it just about the same as the transmission limitation which is the right thing to do... about 175-180 would be my guess.

 

The factory does set the limiter at 158 mph. It's clear by the acceleration and RPM that the little cars stand a chance at touching 170 mph. I don't think they have the wheaties to do much more, but that number should be possible.
We know that Mercedes can remove speed limiters on their vehicles via programming. That's evident by the performance packages available on various AMG models.
An SL55 has a top speed limited to 155 mph. An SL55 with the 030 performance package has a top speed limited to 186 mph.
The SLK55 with the performance package has it's limiter moved to 172 mph which is more than enough for such a short wheelbase.

It may be possible to remove our limiter also. One of my techs mentioned last night that it was stored in the ME. We might get into it to see if it can be accessed.

Yes, I'll still sell the car. Needs outweigh wants. Besides, I've got a little black car with twice the power of the SRT. It's getting a suspension upgrade this summer so it will handle in a similar fashion too.

 

Anyone that tunes the ECU, Kleemann, Renntech, Powerchip remove the limiter and push it to the number set by the transmission.

 

Yep...I've had mine to 165+ mph before I backed off due to road conditions, and it was still pulling pretty hard when I let off too.

 

Okay, my next mod is just going to have to be Renntech.
