Would my car have some sort of rev/speed limiter March 20, 2006, 09:53:23 PM I blame this all on the fact that my speedo reads about 20 mph to fast. Some times if I really give the cougar hell and take it to red line. She will just fall flat, like the fuel got cut off. But if I shift to the next gear and keep on hammerin it it will just keep going, like its not the speed. But could it be the revs? Its weird and I rarely take the cougar up to those high rpms but I was just wondering if maybe my car had some kinda limiter. Quote Selected

Now that I have the 245/50's and a trac-loc it wont. With the old 235/55's It would. Man If I still had 14's on the car I could roast them through third. But now I've got too much realestate to turn back there. Quote Selected

I don't know how high I've actually had it, but I know its been into the red zone on that turbo coupe tach. Wich is working well now for some reason. Quote Selected
