GT4 Running in?

Very interesting. Keep away from flipped cars in that case..gtsralph said:
Thanks, that’s a great read. Must say I have looked at a few second hand GT cars, some with very low miles that I had major concerns with their running in - one in particular I suspected as possibly having been tracked out of the box by first owner then flipped After 12 months.
The link does make for good reading.
For GT cars, though, I continue to follow the Andreas Preuninger running-in process, which takes about 1,000 miles to complete. It also seems to make more sense to me in that it allows for a gradual increase in the use of revs, starting at about 500 miles, and then reaching full revs by 1,000 miles.
I do buy into the fact that Porsche's engines feel stronger with several thousand miles on the clock - my CGT with just over 20k has never felt stronger!

Wondering what’s the wisdom for running in please?
Do what the owners manual states rather than what some random person on the internet suggests is "better".finmac said:

That is a great read. Surely it's common sense that these things need running in ! As that article explains it's not just the engine. I'd certainly be wary of cars that are flipped having done a few hundred miles.
while it's common sense 1800 miles at 4k is daft and not the way to run in engines.I went with the AP run in route and my dad has done for 70 years and his company cars rev off the speedo at 120k miles.
200 miles keep below 4k revs then up it 500 rpm every 100 miles. Never lug an engine or load it, never do motorway work and change gear a lot.
then let the car run to max rev for 5 seconds even at 600 miles and coast back down.
wearing in a engine for 2k miles at 4k will make for a lazy engine which will take another 20k to run in right !
same with brakes if you don't go above 4k and nanny your brakes you will have gazed pads and get "brake squeal" like 80% people seem to have, mine don't squeal and I have 3 cars with CCB !!
you need to seal the glue in the pads and do a few heat cycles but after than you really need a good few 120 mph stops to get pad transfer if on steels.
all this is common sense imho not 4k revs for 2k mile lol, and why AP said as such in his vids.
Also when you get in your car I stay at 3k for 2 miles then 4k till I have done 5 miles without fail.
EVERY and I mean every car meet you see ALL owners reving engines out the venue from cold for the you tubers and spotters, I just don't get it but 90% cars are NOT owned and will not be kept over 3 years.

I followed this process with my 718 GT4, didn't give it the full beans until around 1,200 miles. Now at just under 4,000 miles and the engine continues to get stronger and sound better.I do buy into the fact that Porsche's engines feel stronger with several thousand miles on the clock - my CGT with just over 20k has never felt stronger!

Remember, after running-in get an oil change done.
Many will argue with you (including your OPC) that it doesn't need it. I always have it done.
Cheers.
Porsche themselves tell you it's not needed as it's not part of the service schedule. Not worth doing unless you want peace of mind i.e. it's for your own benefit not for the benefit of the car.Many will argue with you (including your OPC) that it doesn't need it. I always have it done.
