    997 turbo rear wing

    hi guys,

    i was just reading an article about new 997 turbo at motortrend.com and found interesting fact:
    they say that the rear wing of 997 turbo is generating the force of 273 newtons wchich is exactly 27 kilograms (at 310 km/h). is that true? for me it's of little value
    what do you thnik?

    Re: 997 turbo rear wing

    The one on the 996 TT generated 9kg I think. So the new one (which looks pretty much like a clone of Techart's version) is better.

    Re: 997 turbo rear wing

    The extra downforce will be of value when you're at that limit (310kmph as stated). You'll fear for your life the equivalent of 18 kgs of downforce less

    Re: 997 turbo rear wing

    Yep, and getting downforce on the rear to balance the natural downforce on the front at speed is always the challenge.

    Re: 997 turbo rear wing

    I'm a little surprised that these numbers are so low. Many years ago the rear whaletails put out about 400 lbs of downforce. Perhaps with all the cleanup UNDER the car they don't need as much? I don't think so. I would check your figures again.

    The cars were also 400 lbs lighter . From what I've heard they've also cleaned up the underbody.

    Re: 997 turbo rear wing

    I think it is a tradeoff between drag and downforce. Nowadays, the drag is also a value which is used a lot in car comparisons. Big wings generating much downforce will also have huge cw values.
