am getting bit of fibreglass work done on the bonnet, am putting in some NACA ducts, question is i have seen some guys do a hood over the top and some that don't. is it worth doing the hood with the ducts? case in example PSIDUP doesn't even have the ducts. fibreglasser is speaking to his aero guy, wouldn't mind seeing what others have done/seen.
PSIDUP no ducts etc
MrMad Torana has both ducts and bulge cover
also same goes for intake pipe/manifold does it need to be covered at high speeds so the air can't come in under the bonnet? because of the angle of the bonnet can't think of anything that would suit it in the way of a reverse cowl etc. possibly some sort of air splitter at the front of the pipe, push the air around it a little or over it? oh n yeah that is a swan pot holder in the background this is what im working with:
