Neil, please stop posting pics of carbon eye-candy to further tempt me!
Otherwise I shall have to set one of my minders on you! : -
Re your question about adding an air scoop in the bonnet, I think it would be pretty tricky to get it positioned efficiently for the filter and at the same time not looking somewhat random and untidy externally, even if carbon.
Btw, there's now no doubt in my mind that our OSIR carbon bonnet's extract vent near the turbo, does a lot to expel hot air under the bonnet and contribute to ambient coolness. Also to draw air through front to back. It's not massive but every little bit helps.
Re getting extra air to the Twintake, please read my posts (Reply #350 onwards) in the Twintake thread I have linked to in my Reply #91 above. I'll now go and post some more info about it there which I've just come home to.
P.S.- I'll get back to you re small carbon engine cover soon.
[No wonder I don't have time to work!]
