I ran the interior course at a Red Line event at the speedway last year.
Interesting to see that on the interior course the RUF 911 hit 114 on the back straight and 136 on the longer front. With my box stock SRT6 I ran 110 on the back and my buddy hit 130 on the front.
Not bad for a "leftover old design" with that horrible recirc ball steering.
I have no doubt the SRT6s running will hit the rev limiter (maybe one will exceed that because of some ECU work

).
