Further info on GT2 drag coefficient:

Despite a monstrous rear wing and a low-riding front air dam, the drag coefficient of the GT2 has increased to 0.34 from the Turbo's 0.31. This increase results mainly from the bigger air intakes that channel more air to the brakes and to no fewer than three radiators and two intercoolers. The key aerodynamic improvement over lesser 911s is the larger center intake that guides air through the main radiator before sending it through a full-width duct to vents between the nose cone and hood. This substantially increases front-end downforce and, at the same time, reduces the amount of air that passes between the road and the floorpan by an impressive 60 percent. The ground-effects front end pays off at speeds of 80 mph and above, tying the nose down in a thoroughly convincing manner.

Between these two cars at the drags it comes down to this.... the driver who makes a mistake loses, plain and simple. A 0-160 run is going to be posted My hat is off to 9Eleven. As for needing more power....why not? Kevin
Awesome man, can't wait to see his numbers and better yet use this thing myself if you are still offering it up to borrow, I would greatly appreciate it Question though, we obviously aren't all in the same elevation, incline of surface or w/e, does it vary the times if there isn't a complete flat surface? Might be a stupid question but there aren't many flat surfaces for miles I could test on here in NY

Not at all. On my m3 I did the csl cf roof swap, everyone doubted the swap, this and that and had no first hand experience. Almost 100% of the strength in these cars are in the a-pillars back, it didn't change the rigidity of my car one bit and saved some good weight. Now my Turbo has no sunroof either, its aluminum not steel to my knowledge and when I wash my car the center pushes in, its very thin, same thing would happen if it were CF!

Martin, the satellites are always watching... If you go to the graphs on 9Eleven's runs it will show you slope deviation. I think on his 0-160 run he had a downhill slope deviation of 130ft... but the overall run was 2958.31 feet which is less than 12" for every 22ft. Close enough to get a good idea of the vehicles performance. If you cannot find a good level run...do it both ways and average the results.Kevin

Ahh I see, very cool. I have an almost flat area for well over a mile and no traffic late night, but I couldn't do a 0 start, its a highway, we'll see. BTW haven't viewed his charts yet, I'm on my phone so its hard to see it clearly
