Greg, I can't remember if I've asked this in the past, so forgive me if I have.  

How is the air from the boundry layer divider [diverter?] going to get out around the plumbing conduites [running back from the firewall]?  
From this last front shot, it looks like the 'conduites' are sorta 'fencing' in the air the would normally get diverted out the sides.

I'm sure I'm missing something [just the angle of the shot] but thought I'd ask.

She's going to be a speed demon!!
