I took some hobby shop aerodynamic balsa wood, baseboard moulding,and blue tape and created rudimentary fairings for the driver's side mirror.
It's pretty crude,but the tufts show an improvement.The flow is not along the axis of travel and I'll have to 'bend' the fairings to align with the flow,now that I can 'see' it.They're like airfoils approaching stall right now,but straight flow off their tails.
This morning I found an alarm clock at the thrift store for under $5.
It's shape is exactly like Porsche used on the 1996 911 GT side-views.I can make a mold from half of it and layup some housings for elliptical glass.It couldn't be better!
Yep!,I need a 12-step program!
