Sauber C30 Ferrari

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

In F1 cars, the diffuser rarely if ever chokes all the way, due to the step plane.

This seems odd... In the video found at http://www.f1talks.pl/?p=11635, labeled factory tour 1 (at the 5:19 point), the mechanic is holding the now standard oval (flattened) exhaust collector used to blow the side of the diffusers by everyone else.

I think what n smikle means is that Sauber has been racing without the off-throttle EBD.
I meant that they blow over the diffuser like in 2010, instead of using the "cannons" that blow across a strake then into the throat of the diffuser as RedBull, Merc, Ferrari, Mac, TR, Lotus, Williams, HRT and FI are doing this year. I think they have tried the cannons in a race or two though.

On the Off throttle blowing, I think Sauber do have the hot blowing engine mapping though, they just haven't figured out how to properly make the RedBull style diffuser to work, so they just hot blow over the top of the diffuser. I will check a youtube video or two to make sure.

If you set the car up with a bit less rear wing, you will be ok on exit as you have the downforce from the exhaust gasses, but on entry and braking your car will be very unstable.
i thought diffusers created downforce across the length of the floor, so its downforce would only be somewhat rear-biased.

Yes but the effect will still be quite noticeable.
