Can anyone explain why NASCAR went for a splitter on the COT instead of the traditional air dam, or how a splitter works differently than a dam?
I know just a little about aerodynamics, and it seems like the splitter will create a lot of turbulence which makes it harder to control the airflow. A dam just pushes the air out of the way.
I think this is a question for our resident Nascar Professor, Flash. That is if he can get out of the doghouse long enough to answer! Or if he's not traipsing through the graveyard looking for flowers for wife of flash! ~LOL~

Sorry I,m late Mrs ( fell in a hole ) besides my dog Max lives in the house.
One of the hardest parts of the Car of Yesterday to police and easiest to find an advantage/cheat with was the shape of the front air dam, remember all the times NASCAR attempted to equalize competition between makes by changing its shape/height?
If you take a close look at the COT you will notice the entire nose piece is Identical from make to make and team to team ( remember Hendricks attempt at working outside the box? ) NASCAR went this direction to ease and speed up Technical inspection.
Utilizing the splitter also allows teams a simple and easy way of adjusting front downforce ( the splitter is adjustable fore and aft ) without spending tons of money in a windtunnel.
And just to prove me wrong its turned out to be very tough and reliable. Although it does a cruddy job of mowing the infeild.

It turns out that it does a great job of getting stuck under the safer barrier, though :-) I think there was a red flag at Dover for 20 minutes while they got that sucker unstuck.
I thought that adjusting downforce with the air dam just involved moving it up or down. No?

Once again Prof. Flash imparts his vast Nascar wisdom upon us! Thanks for the info,
and next time take a flashlight, don't want ya gettin hurt on the fresh flower missions!

Reason: added floral arrangement ~LOL~
not to mention it makes a new weapon in the arsenal of tire cutters on the track... a precision driver can use his splitter to slice the sidewall of a faster opponents tire, hereby taking him out of the race! works good at knocking valve stems off too.... oh well remember the video game you could shoot tires at your opponents? hmmm wonder if they can do that too with the COT!

On the old car the air dams/front area shape/contour made HUGE changes in downforce/drag ( think of it as the leading edge of a aircraft wing ) and some teams were using it to actually Tune how there cars Turned into and through the corners, look at one of the pre COT cars especially Hendricks/Gibbs/RCR and Evernhams cars from 06 ran at intermediate size tracks you'll notice the left front edge of the air dam is pulled WAY OUT past the tire edge and the right front is pushed in almost flush with the right front tire. You'll also see a more pronounced ledge just above the air dam/bumper and the grille, that small ledge is HUGE for downforce tuning.
THEN compare THAT to a Super Speedway Car!!!
If theres one car thats very accessible and availible for some close up photography at various angles in Super Speedway RACE TRIM ( dont think this hasnt been done by more than one Team ) Its Kevin Harvicks #29 RCR/Shell Daytona 500 WINNING Monte Carlo ( I hate the paint scheme but it has a BEAUTIFUL BODY ) currently resideing in Full Public view at Daytona USA in Daytona Florida!!! Its probaly the most photographed car in history with the exception of a certain Black #3 that sat there a few years ago.
THE COT CARS getting rid of all that mess, call it a Spec car or a IROC style race car or say ALL OF THEM ARE THE SAME ( not true by the way ) the COT will over the next season or two IMPROVE NASCAR RACING!!!

NOOO what driver would do something like that??? LOL Luckily the COT car is proving itself to be a TANK ( and a Safe Race Car ) that sucker can take some abuse and Still be Competitve. I think We the Fans are going to start seeing ALOT more Physical style of racing than was possible in the early 2000s aero dependent race cars. And I,M really looking forward to that.
