If you look closely at the #4 entry you will find that it just says Porsche 911, but it is in a class above the 997RSR.

Having gone to the Altzen motorsport site, I discovered that someone in their guest book is suggesting that they may be entering with a 1300kg easy 997 turbo with a large KKK turbocharger and 1,1bar load pressure, with a Wide Body Look.

Wow!, that would be something.
