Rosco's haynes Build

Also I'm thinking of using a cone filter with a cold feed, mounted on the front like others have done

Change of plan haha I've just seen this idea, it clamps a foam/k&n filter between the two plates



Also the injector height could easily altered to keep it as low as possible and altered if it causes a bhp drop,

Right well I've mocked up air box idea number two just to get an idea of size, looks ok, I've mocked up a bit of wire to represent the bonnet line roughly, also I'm a bit worried about induction noise with this method as it's got to be less than 99db at 3/4 throttle!!! Is there anyway of getting this rpm dropped, maybe a new power graph showing peak power at 8000 rpm say??

If needed, could the bonnet not form the top cover/half/something of the air box?

From what I've heard on other forums you are the one supplying the information about the engines peak power so if you want 8k then that's what it is!
My peak power on my MX5 engine is going to be 3000 rpm - er - no I don't think I'll get away with that - so as long as it half sensible .........

yeah i thought that but i would like to let a good bit of cold air in, im thinking foam filter sticking through a hole in the bonnet, then ive not got to mess around with a scoop or anything, just cut a neat hole in the bonnet

yeah that sounds good, I'm going to get it mapped so will see where it gives peak power
