Apparently the crankshaft used is the exact one from the 911 GT3 RSR race car. It sounds like an actual race car with registration plates, a 7:27 ring time is the claim.
If that is true, it's only 3 seconds off of the GT2 RS time and a massive 13 seconds faster than the 911 GT3 RS. The "standard" 911 GT3 is 7 seconds slower than the GT3 RS. All of these times are for Sport Auto by the same driver, Horst Von Saurma.
So, the difference between the "Super Extreme Hardcore" Porsche, and the "Super Hardcore" one is almost double the difference between the "Super Hardcore" version of the "Hardcore" one.
And breathe out...
