Looking at doing some air vents in side of bonnet, but can't decide what to do.

Opinions welcome, or other options.

how about top of nose like a caterham

Was thinking of that too. But I think i need one on the side too, for the carbs to get more air.

I'd go with the first option, but cut to fit round one of those mahoosive pipercross airfilters sticking out the side of the bonnet!

Thans Hugh

Already have one of those airfilters but the carbs sit low down, and i have a very short inlet manifold so don't think this is a option.

how about a naca duct feeding the carbs?

or a duct from front of nose cone with an air feed to carbs!

Cheers Daniel

I like the idea of ducting from nose cone to carbs. Where's the best place to get ducting etc. from
