Some pretty impressive numbers, especially from the Porsche.
Here's a test
Road & Track did a while back;
The 911 turbo has the X50 power package with 450hp. Even so, its amazing how fast the rear-engined Porsches are.
Another thing to notice is, the Ford GT would
kill the S7, its over a second faster...
And some various cars
Road & Track had tested over the years, and of course, lots of Porsche 911 turbos
