It maybe only a matter of a hole in the glasswork and my engine is mounted in original SBF area by poly bushes and plates so not a lot of movement.

I could run hosing or some light alloy piping etc to in front of radiator and use pod type K&N filters or make my own foam style filter, but having a minimum of 3" diameter plumbing is getting big. My first thoughts were to make a duct attached to the underside of the bonnet but then there is joint issues where the duct connects to the carb.

The other issue is ensuring the 600+ hp engine gets enough air, we did dyno runs with no air filter and one using a 3.5" x 14" KN Nascar 2 ply filter and no difference or hp loss, and that was with a 1-1/8" air gap for the air to flow over the filter base, but that filter was over 4" higher than the bonnet and looked hideous, so whatever I end up with I am going to curve the scoop and still have 2" normal looking front entry and the main thing is not to have the a wide square air filter/box as this makes the scoop to hard to look round when I will be trying to line up the side of the track.
