Top Speed for '04 GTO

Just wanted to clear up something that is the topic of a lot of posts... The top speed on the '04 GTO is 160mph. Last night the speed limiter was kicking in at exactly 160mph, it felt like I had just hit a ton of bricks when it kicked in, and it doesn't take long to bounce right back to 160!

Now, just need to find a way to take off the limiter and find the true potential!

Are you sure it is a speed limiter? People used to think that the Z28s had a limiter but it was only the cars that were not delivered with Z-rated tires from the factory (115 mph). It turned out that the "limiter" was the electronic ignition turning off because the engine had reached red-line in 5th gear (172 mph). The Z28 would not pull 6th gear at that speed. A couple of military guys stationed in Germany figured this out on the Autobahn. The GTO is geared a bit lower than the Camaros LS1s so this may be what is happening in your case.

I wouldn't encourage anyone to test this out on the GTO. Beware, at 120+ it takes forever to stop and the '04 GTO's brakes aren't its strongest suit.

what happens if...

if a cop catches you going 160mph will he likely put you in jail and take your car away? maybe even charge you with some kind of felony?

I thought there was a 160 governor on our cars. The guy that got rid of my skip shift said he would raise it to 255 when I bring the car in for tuning.

I checked it coming home today. 160 is redline in 5th. No I did not go that fast but 2,000 rpm is 53, 4,000 is 106, thus 6,000 is 160. I haven't read anywhere or in any report that the GTO has a speed limiter. I think this most likely is the electronic ignition turning off at redline.

You be a crazy man! What if a tire blew or a deer ran out? I've been up to 132 in my vette and I saw God.
You be a crazy man-don't do that again!
