My latest version tries to approximate the template lines I projected from overhead in post #29: http://ecomodder.com/forum/showthrea...tml#post245629 EDIT (image added):
I wonder about an end plate now that might start from the side of the car, just aft of the rear side window and "grow" into a plate that would capture that sideways moving downdraft from the roof, redirecting it to the tail. Just wondering. My fabrication skills are weak, so I am becoming reluctant to keep trying these until I have built more of the simpler forms, like a new grill block, some good looking wheel well skirts, airdam, undertray... I'd have somewhat better skills for this ... |
California98Civic,with respect to the plan-taper of your car,I would establish the rate of curvature from your elevational view 'Template',using the height of the car,then transpose that curvature onto the plan-view of the Civic.
It looks like the body taper begins around where the center of the rear tires are.Try to dovetail onto that spot.
If you use too 'fast' a curvature on the sides,you'll lose your boundary layer and trash the airflow.
Also,you might set up attached longitudinal vortexes ( really high drag ) as the slow side flow intersects with the faster downwash coming off the roof.
