What top speed MPH is the assy. line GT500 limited to?.......

[Robert M]

I know that the 2003/04 Cobra was limited from the factory to 159mph in the computer. I read somewhere that the 2007/08 GT500 are also limited from the assy. line, but I don't recall to what MPH.

155mph

155. Some have hit 156-157 before the governor took over.

My understanding, after having owned a 2003 Cobra and now a GT500, that the factory has a computer limiter of 155MPH on both vehicles; same as with the German cars.

PCars don't have this limiter in them. My 997S will hit 184mph.

Thanks for the replies. It could have been 155 on the 03/04 Cobra, I thought it was 159. When the limit is met, the fuel is cut-off? is this correct?

Yes, same with the rev limiter... No fuel=????

I only hit a tick over 140 before I ran out of track last weekend. The car was still pulling like a freight train in 5th gear at that point! epper:

The reason I was specifically asking about the fuel is because a new Super Snake owner on the Shelby forum has done a top end pull (actually 3 of them) in Fla. The car is shutting off at his GPS reading of 163mph. I know with the 20" tire/wheel change there may be a difference in mph, and the computer/VSS may be seeing something a little different from what his GPS is showing. I also know that some manufacturers use "spark" to limit mph. The spark limiting usually allows the car to run, although poorly, once the limit is met. I was wondering why his car is shutting off? I was unsure of how Ford limits mph. Cutting the fuel source would definitely kill the engine, I just wanted to verify that fuel was the way Ford limits mph, and there was not another issue.

I thought the factory always placed the limiter at a speed which was within the limits of the tire the car was factory equipped with hence the 155MPH limiter.

This is true, U.M. has got it right.

The GT500 is factory limited because of the 2 piece drive shaft not for the tires.
