We all know about NACA inlet ducts Does anyone know about outlet ducts ,do NACA ducts work to draw air out of the fairing if fitted backwards

AFAIA any hole as long as it's in a low pressure area will let air out, all a properly profiled NACA duct will do is reduce turbulence (drag) when reintroducing the exiting air into a laminar flow, I don't believe they actually pull air out, but I've been wrong many times so don't take my word for it, there is lots of reading on the net, some of which may be correct Big smile .
Ian, racing again No 6.

I think he saw that video:

So yea, they kind of do - if that is indeed that case, that is.
But what do you need it for? Boundary layer suction?

After the worlds this year I was wanting to increase air flow to the rider and we noticed no out vents on faired bikes

Probably only an issue if it was possible to build a sealed bike, but as long as it has wheels in contact with the road......
