He's free to calculate it if he pleases. I'm not going to up and do it becuase he thinks it has a big effect.Fil wrote:'Mr Pirelli P Zero' may have a point you know.
In your images on the previous page, the contact patches are only horizontal lines (and by my understanding, the front-most part of the tyre's contact).
With an actual contact patch at least 4-5x this length, would this not create a much more pronounced, or (at the very least) a later occurring low pressure zone off the front wheels?
And wouldn't this then interact more significantly with the barge boards, sidepods, floor edge & subsequent front exhaust effect?
Oh, and he did specify 'rather large'. So, hold the fries!
I think rain will affect the effectiveness of the FEE or even driving beside another car, am i goin to even try to figue that one out? No
There are a million and 1 things that anyone can consider, and it's easier to say it than to do it.
The contact patch doesn't change the fact that there is over 640mm, or so, of tyre left in the free flow.
Thus the general flow wont change much, just that square patch will increase in size and a little change in drag, lift etc; it wont add a revelation to the discussion.
I've done the spinning wheels plenty of times and the effect is noticable but minute.
The patch size is really an unnecessary at this level of discussion, and is probably extremely tedious to calculate without even knowing what downforce the r31 has or even the pirelli tyre behavior itself; much less at speed.
These things have an effect yes (i don't know why it has to be large), but that would be taking the thread too far into another realm.
