There is much more room at the back and the bonnet is a bit higher. The front is much closer to "things" all round.
which would be the better location?

I'm going to change my airbox by fitting a bigger filter and bigger inlet pipe in the hope of letting more air in. I want to know your thoughts
for the best place to fit it. The picture shows the prototype box. The two places it will fit are infront of the box, partly under the nose cone,
right behind the radiator and behind the box next to the battery and infront of the fuse box.

WOW
hes made a wooden engine !!!
wont the fuel/air and sparks make a mess off it ??

The new airbox is made of GRP, and is a better shape than the wooden prototype.
I would say front as you'll be getting cooler air.

Cooler air = denser intake charge=more power!
Cooler air is best, I agree. I'm not sure that just behind the radiator would be cooler but it might be. The rad is mounted high in my car so
that the pipes clear the chassis tubes but that means there isn't much room above the rad for cold air.
Air temperature asside, would there be a problem with having the air intake at the back of the engine bay?
what about the cateringvan's which rely on the louvres on the back of the bonnet? cant get cooler air than that! plus it does kind of account for
forced air...
they must have thought it through after all these years and it is probably the best location for an airbox.
Stick it at the back and duct some cool air to it.
I agree with Phil - keep it away from the rad and duct air into it.
You could even take it one stage further and run a flexible pipe to the filter mounted in a position in the airflow.
Use a NACA duct if you can as these are more efficient than using louvres or scoops. Just make sure you buy or make a properly designed duct as the
shape is carefully calculated.
As already said, try to find a source of cool, undisturbed air for better density. I'd probably be tempted to try the surface or side of the
bonnet and use a pair of NACA ducts.
