Wind Tunnel

["Keith Turk" <kturk@ala.net>]

Just some basic information on how the tunnel turned out...

We started with the car in the 260mph attitude and set up exactly like it came
off the salt last year...   the CD was .271

When we started lowering the spoiler it kept decreasing more and more  with
each 5 degree increment until we basically removed it... and found the CD was
around .214  ,  We then built a bit different spoiler that ended up 7 degrees
down which equated to a cd of .205

We tried a couple of different things with the scoop and nose and found a bit
of downforce with minimal increases in drag... and the new scoop was a bit
better... as was fairing the back of the scoop...  Our best CD was .170 in an
illegal configuration... ( the goal was to see how much a canopy would help. )
But I can get it down to a Real .200 in a drivable condition.

The whole deal was one of the best days I've spent in my life... it was so
cool it defied description...   Gary Eaker (A'ker ) can't work with most Cup
teams that come to his tunnels ... seems they don't want him cross leveling
information... so he just gives them the keys and collects the data...  they
do the work... in this case he really got into it...  can't say he'll be there
when you are... but I wouldn't count him out...  He's a member of the Bville
200 club and loves this stuff...  I got WAY more then I paid him for...  the
first two hours cost 690 bucks... after that Gary just gave me the time (
based on me bringing the Camaro next month ) we spent a total of 10 hrs there
with 8 of it in the tunnel... total blast..

post it )
