Does anyone know? I was asked by a friend and didn't really know the answer.

My poor memory tells me 183 give or take a few mph.

Per Porsche 180 mph for a narrow body or 177 for a wide body (C4S). A narrow body is rated 2 MPH slower than they rate the 997 Carrera S at 182 mph and 2-3 mph faster than the regular Carrera at 177 or 178. The 996 C4S has a rated top speed of 174 mph. It depends on what source you look at, but Porsche has published the narrow body 996 3.6l at 177 and 178 mph. The primary reason why the 997 C2S is rated higher is not because of the HP, but because of the different gearing.

There are so many variables that woudl effect it... aero kit or not, windows down or not, ride height of car. The X51 should add 2-3 mph in an identical car. I've never had mine over 165, but been there MANY times (on the track... mostly)

BTW, when are you going to race that car?

OK, I can see it on an oval. I hope to be in the 165 neighborhood later this fall at Daytona. I have an X51 as well but obviously I have to run the stock gears in PCA. I'm surprised you can get that much speed with cup gears. You must have your rev limiter turned up a bit.

How do you guys get on the track with the Nascar configuration? Are you doing it with car clubs or through other connections. I'm asking because I've heard of clubs will running NASCAR tracks with a straight and a turn or two with an infield road course, but never the full track.
I'm asking out of ignorance (I'm still relatively new to this), not challenging your statements.

Jim,
I think I was hitting about 155, confirmed with rpm, not speedo, in my 993 through the trioval at Daytona I really didn't have too much time or nerve to look but it is obvious you are flat out flying, you will see what I mean in a month or so. My guess is your car will easily be at 165 unless there are some wicked head winds, etc.
