Last year I had the pleasure of meeting Andreas Preuninger, head of GT car development at Porsche. This was at the 997 RS 4.0 litre preview in the UK.
A few of us asked about running in. He said the following:
- For the first couple of hundred miles drive the car gently; no high revs and don't let the engine labour. The main thing here is bedding in tyres and brakes.
- Up to around 500 miles, vary engine load and speed. Use perhaps 2/3rd of the rev range (when warm of course). No full throttle.
- Between 500 and 1,000 miles start to use more of the revs, and larger (occasional full) throttle openings. (I tend to up my rev limit 1,000 rpm per 100 miles.)
- Beyond 1,000 miles drive the car as you wish.
He confirmed that most GT engines develop their full potential around 10,000 miles - most 3.8 RS engines were over 460hp (10 up on OEM figures) at this mileage.
I've pretty much used AP's technique for years now - most notably on a 996 GT3 Gen 2 that has now done 60,000 miles, half on track. The engine uses no oil, and still develops 430 hp (it has a Manthey map and exhaust).
Anyhow, thought I'd share.
Cheers
