How many miles did you guys put on your cars before driving them hard and going to the track? My buddy at the Ford dealers says drive it hard right from the start. That way the computer learns your driving habits and the car performs better. I've heard the same from several guys.
I bought mine slightly used, 7k miles... So I didn't really have to break it in or anything. Usually I just drive a new car easy for 1000 miles just to be safe. That's what most recommend. I drove my Stang easy for about 500 miles then I had my intake/tune and broke it in the proper way, which was pedal to the metal & she reponded quite well
Modern engines are ready to drive with no break in period.
Then how do you explain Ford programming the onboard computer in my 2008 GT500 to prevent it from exceeding 4000 rpms for the first few miles or 50 cold engine starts?

I've never heard of Ford doing this and I've had several. I always drove my new cars easy until the oil was thoroughly warmed up and then dropped the hammer. I know that my last two Mustangs had no such limits on their computers and I can see no reason for Ford to do so on the GT500.

I know a few guys who bought new 2007 Shelby GT500's and have never heard this before. Something sounds fishy about that. Unless it's something new for 2008.
It's always possible they do something a little different with the hand assembled supercharged 5.4 than a regular production motor. I would say it has more to due with the supercharger and running boost at higher rpms than the engine itself.
I don't know!! I'm still trying to figure out why my 400 hp GT kicks the crap out of 500 hp GT500's at the track.
Nope, Gary Paul is right. I've heard of several ppl with GT500s having that restriction. Shelby autos said that without proper break-in, you will have problems. Some of your friends may not realize it, but it is there. I actually read a little bit about it when I was waiting on my salesguy to come so I could order my Bullitt. New anything... you should break it in. Try installing new pads and such on a car and being hard on them... there are problems.

Stock as can be, just trying to reverse the damage the previous owner caused.
I think it's far more important to wait until your engine is up to normal operating temperature every time you drive it before you give'er than to wait for 1000 miles.

I believe I heard that the GT500s are limited the first 64miles from being driven hard to prevent any dealers joy riding and lighting up the tires before a buyer came along. I mean for a 20K mark up I wouldnt want a abused car.

That's a pretty good idea... If I ordered a GT500 I would wan't to be there the day it came off the truck and probably wouldn't leave until I was driving it home. Paying that kind of money, I wouldn't wan't anyone driving this thing. I don't trust the people at dealers with fast cars, I used to work for them and alot of them will beat the crap out of a fast car anytime they could. Especially during dealer swaps
My car has 128000 miles, and has no issues whatsoever. Good compression, no idle, no smoke, no problems.
I usually put 250,000+ miles on my cars, and keep 'em a while. My old truck has about a million miles on it. I put 250,000 my brother put 250,000 and my uncle used it driving back & forth to Kansas City (140 miles a day/6 days a week for 10 years). The engine didn't give out on it, the floor rusted through.
Like I said, if you take care of the engine in the break-in period, it'll take care of you.
I agree with this.
I'm not one to break an engine in softly but I'll wait until around 1K to hit the redline. I also avoid trolling along the hwy at a single rpm, its also good to accelerate and then allow it to decelerate w/o braking. And it might be a little anal but the first oil change comes at 500. With my bikes the first is at 50...yeah thats really anal.
& she reponded quite well
