Printed NACA Duct
 Printed NACA Duct
 Trial alignment after cutting
 Bolted on for proof-of-concept testing!
 In the pits...
 ...and on the track for a successful test.
 Bolts out...
 ...Bondo and spot putty in.
 I think I mentioned that there was sanding involved in this project...
 Fixing the seam and sharpening those corners!
 The first look after rubbing compound. Shiny!
 Mold release applied and mold starting to take shape.
 Finished mold just before pour...
 ...and just after!
 Great surface on the urethane mold.
 Laying out the fiberglass patterns with paper towel.
 First pull, extremely light!
 Nice sharp corners, very few air bubbles.
 After paint...
 ...you can see some pinholes and the mold error. Not to worry, this is just a prototype!
 A quick filler job will take care of the imperfections. 
Prototype finished and waxed
Mounting bracket jig
Brackets epoxied on
More brackets
Excellent fitment, good gaps!
Looks good...
And just clears that headlight
Tight tolerances on the sheet metal
The air path to the filter
Stock plastic work fits too!
