OBJECT

The object of the current t ests was to develop a low drag vehicle with good'
handling c hars.ct er is t ic s o Because of the lack of a definition of what a good
handling vehicle at race sp eeds on var ious tracks is, a list of alternatives
relative to handling, along with assoc iated drag penalties or benefits, was
to be developed for future- use cb tne track.

ONCLUSIONS
O

lo- Use of the recommended nF” Series race package (assuming handling and
other variable do not deteriorate) should result in a 5 to 6 MPH lap
speed increase relative to the existing race car.

2. By varying body rake angle and front under nose spoiler position and by
using rear deck wings and vertical stabilizers, lift and side forces
acting on the race car can be varied widely to improve handlingo

W a the proposed nFu Series package should be tested extensively at the track
to determine the proper body rake angle, front undernose spoiler and real'
wing settings required for proper liandlin

ro ® Any future tests aimed at improving the recommended package should con­
centrate on the nA” post region and further aerodynamic tuning of the
front end.
