I have a GTS on order, hoping to arrive soon. I also have a long weekend driving trip that I hope the new car will be available for. But the time between delivery and the trip is really compressed, so little break in time before the trip.

So tossing aside all the long break in discussions, how hard to you push it and how soon?

Rev to miles match? Day one, day two, day three limits. Other than just an easy day one or two, flog it day three?

PEC seems to send it day one, pretty hard.
Many do the rev to miles match
Everyone will have a different view.

I don't keep cars long, and it will be under warranty the entire time I drive it.

Any specific prep work prior to a trip?

I once did break-in miles in 2 days, because I had a scheduled dyno slot for my new engine and didn't want to miss it -- this was fully built engine with crazy internals and head work.
I drove the car 500 miles on day 1, up/down the Delaware River, ie not highway miles. On day 2, we did an oil change that morning and I got back on it. Dyno tuning was day 3.

Granted, that's pretty hard core and not for everyone.

I would focus on racking up a couple hundred miles on the backroads (with elevation changes and engine braking) before subjecting it to the highways.
Your upcoming trip has a lot of highway miles to get to the fun. Once you're on the road, I wouldn't let it sit in one gear for long stretches. Change it up to exercise things.

Good luck and have fun!

Even if you don't make it to the break-in mileage for your driving trip, just take an off-ramp every 30 minutes until you reach that magic number and that'll give you the varied load you're looking for.

Everybody has a diff opinion this, but I tend to think break-in routine is overdone. According to this vid, every engine is run at full throttle for 90 seconds after it is warmed up, right after it is assembled. Personally, I would be sympathetic and be sure to get it fully up to temp before high revs or power but I wouldn't be worried about rev or full throttle.

break in is overdone. Agreed on that. also drive the car conservatively and you shucked be good. give it all RPM ranges, dont drive on one rom for more than 5-10 mins, keep changing gears when on manual, make sure the engine has enough heat cycles. dont hit rev limit every gear, simply put, be nice to the car and you should be fine.

also I think most manufacturers believe that no-one will follow break in rules anyway.. lol.. its just there in the manual for legal reasons. Todays machining have enough low tolerances and accuracy that they can pretty much make machines like engine pretty solid.

enjoy your car, I am still in the break in for the T. but again I am not a "drive it like u stole it " driver either. lol

Do whatever your comfortable with.

Your car.

I don't know of any car that grenades at 5k because someone didn't follow the break-in procedure recommended by PAG.

Plus, the break-in procedure varies from country to country (or regions of the world, to be more precise). So there's that.

If you don't plan on keep the car beyond the OEM warranty period, does it really matter?

TL;DR do you what makes you comfortable; it's your car

I am not sure how this is different from every other break in question.

I usually break in using a coat hanger.

Mile 20 is more important than mile 520. If it were me, I would keep it under 4K, avoid hard breaking and vary the revs for the first couple hundred miles. After that I would gradually increase the load as the miles accumulate till about 1000 miles.

This is a good middle of the road plan IMHO and what I did. There are so many conflicting opinions on the subject so a compromise is a good plan.

this isn't a gt engine, and there's a warranty - warm up the oil, warm up the tires, redline it off the dealer lot like an adult

I took delivery of my c4s at Atlanta PEC, then drove it home to the DC area (just under 800 miles) going via highways. I basically followed this.

After oil temp got up to 180, every 5-10 minutes, downshifted and rowed a few gears to vary the RPMs, took it to about 5, 5.5k. did a little engine breaking. Also stating the obvious, be conscious of traffic around you when doing this. Dropping to 3rd and going over 5k rpms took me over 100mph.

Regardless of if you're a 'hard break in' believer like me, or a 'follow the manual and keep it under 4k rpm' believer, one thing both sides agree on and understand - vary the RPMs. Don't just drone on at 2k for extended periods. You should be fine either way (keeping under 4k or going up to 6k), the hard break in people believe that doing so will help seat the rings better and prevent oil loss as the car ages. The one time i didn't do a hard break in on a car was my Audi A4 and that thing burned off 1qt of a oil every 5k miles. All other cars have not had that issue.

Another thing to keep in mind, the break in isn't just for the engine. There's things like transmission, brakes, suspension etc. all bedding in together.
As previously mentioned the first few miles are the most important. Bedding in brakes and keeping in an eye on transmission will also be key in addition to varying engine RPMs.

I’m at 540’ish miles on my GTS and mostly keeping it around the 3000-3500rpm for peak RPM, let the car warm up, and try not to cruise at a fixed rpm for too long at a time. I plan to do this until 1200-1500 miles, and then do an oil and filter change. After that, I plan to raise my rpm limit to 4000-4500 for the next 1000 or so miles. After that, I won’t think about things and just drive as I need to / want to. This has served me well in most cars, so will do it here as well.

Yep, from most of the stuff I've seen published / from interviews the engine is pretty much good to go from the factory. It's all the other stuff that needs break in.

I haven't seen anything Porsche specific, but here is a video about the Z06 engine.
