Most preferred break-in method?

[Deedsey]

I have a build week of 18 April for my Mineral grey 05 GT premium!!!
Unfortunately, as its being shipped to Germany I still have plenty of time to dream about my new baby's arrival. One particular thing I am curious about is the best way to break er in. I've read the owners manual, it recommends to vary the speed driven for the first 1000 miles. I have also heard people talk about keeping the RPM's at or below 3000 for the first 500...etc. Can anyone recommend the best break-in method for my new ride???

Best way to break it in (assuming that it needs any break-in in the first place, which is debatable) is to vary rpm's across the useable rpm range. The whole reason behind this is because metal has "memory". When metal gets flexed or dinged, it retains the characteristics of the trauma. If you were to never take it over 3000 rpm, then the metal will be seated for 3000 rpm's, so its best to smoothly vary your rpm's across a broader range.

HOWEVER, this point is moot, if this process was already done to the engine before it was ever put in your car.

I used to work with a guy that used that break-in technique. He'd say, "Put it to the floor and if it holds together, it's a good motor!" I think he went through quite a few engines that way!

I've been shagging ass in my '04 GT from the minute I drove her off the lot last year. Bu I think I will slow down and break my '05 GT in a bit more zen-like

drive it like you stole it

Hmmm seems the majority is all about putting the hammer down! I may not "Drive it like I stole it" but I know one thing for damned sure! I dont have the patience to drive my first, brand new 300 pony+ car like a grandma for a 1000 miles. I think I will just get the whore out on the autobahn and do a Euro trip! Thanks for the input!

i had heard that if you break it in harder it will always run harder so thats how i did it

I drove mine undrer 3000 rpm for the first 200 miles, then kept it under 4500 for the next 200 miles and then have had my foot to the floor ever since 410 miles. 14.00@98mph at 437 miles, AUTO, MORE TO COME...

Rondosa,
I've read that article and it does look like the correct way to break in the eninge. That is exactly what I plan on doing.

I break in my cars just like I would normally drive them, which is moderately hard. I do go easy on the brakes though for the first 300 miles or so.

I don't think you have to baby your car or drive it like an old geezer.

I normally drive my car hard and did it as soon as I drove it off the dealer lot. My car got no special treatment.

Florida Bob:
Is that the proper way to seat pads and rotors ?
Because I've never been easy on them to start - More like:
Three times: Run the car to 35 to 40 mph and brake moderately.
Three times: Run the car to 55 to 60 mph and brake moderately.
Three times: Run the car up to 90 mph and brake hard to really heat them up.
Then let car sit overnight or for 12 to 16 hours to cool brakes.
I'll have to go back in my records and check but I think that was pretty close to the suggested regimen after installation of my aftermarket brakes on my '99 GT.

Edit:
Well I knew I would be off by a bit (maybe more) so for clarification I pulled up the Bear Website - - -

Just to be clear, I wasn't recommending that break-in technique, just that some guy I knew did it that way. Then again, he may have had a few screws loose!
