Front splitter end plates
Front splitter end plates
(OP)
In looking at some of the most successful hill climb and time attack vehicles, those running substantial front splitters as part of their aero package frequently have very large end/spill plates on them. Key examples would be the Peugeot T16 at this year's Pike's Peak, and several variations of those driven by Tajima also at Pike's Peak.
Can anyone here enlighten me as to the function and benefits of these massive end plates, and how the advantages may outweigh the resultant drag?

I seem to recall even a fairly elementary text like Barnard & Philpott gives some explanation on the various forms of wing tip devices. http://books.google.com/books/about/Aircraft_Fligh...

RE: Front splitter end plates
At the front I see what you mean about it sealing to the sides now. In this case you're going to get a 'bubble' of air to some extent. I suspect you'll get some down force from diverting airflow but it may also act like a more 'pointed nose' - a bit like the bubble in the back of a pick up can act like a teardrop back. May even help force more air through that central grill If I'm understanding the layout properly.
Is this a way of gaming the rules of the race? Is there a limit to length of nose or similar but aerodynamic wings are allowed beyond this? Or perhaps changes to the stock vehicle are limited or some such?
Many aerodynamic features of race cars aren't strictly the 'best aerodynamic shape' but an attempt to get the most out of imposed regulations - be it class regulations for true race cars or various crash safety rules for road cars. Both NASCAR & F1 certainly take this approach.
