Did some CAD work today (Cardboard Aided Design).
For fun, vote on what you think will happen with this massive cardboard air dam in A-B-A testing....
1) Reduced drag vs. normal grille block
2) Increased drag vs. normal grille block
3) No significant change
4) AAAAAHHH! MY EYES!!
(Multiple answers permitted.)
Notes:
1) Same size openings for cooling air in the grille block vs. air dam.
2) There's just over 8 cm / 3 inches of clearance
3) I angled it slightly to lower the stagnation point
4) the floor of the car has about 15 cm / 6 inches of clearance
5) the lowest suspension points have approx 12 cm / 4.7 inches of clearance
UPDATE! For coastdown test results, see post #29
Compared to stock height/angles:
- - - - -
UPDATE - July 7, 2015: less massive, less ugly, more durable air dam v. 2.0 is now on the car.
See
post #89 for details.
