Aero Doodads at Nazareth

Here's photos of the underwing inlets on the Swift 010.c above
and the Reynard 99I below. Notice they're similar but
only two strakes compared with Lola's three. Hence the strake
With the small speedway wings mandated by CART the teams were
looking for every possible pound of downforce. Most teams have
an aerodynamic development program in addition to the constant
development work done by the chassis manufacturers.
It's difficult to see but there is a fence that runs behind
the inside end plate on that kickup. I'd guess that's another
small detail in the ongoing attempt to clean up flow around the
rear tire and create smooth flow to the top of the diffuser.
This is Greg Moore's Ilmor/Mercedes-Benz powered Reynard.
One of the unique mods is what the PacWest guys were calling
"The Platypus," shown here on Mauricio Gugelmin's Ilmor/Mercedes-Benz/Reynard.
Someone told me these two planes on each side of the nose produce
more than 40 pounds of downforce. They also spoil the air and
direct it down into the underwing inlet.
Scott Pruett's PPI crew kept the back of his car covered drawing
my attention to the car. I was told these two delta-shaped planes
help clean up the air to the rear wing. Notice the small rear
wing mandated by CART rules.
