Rosco's haynes Build

[Rosco]

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

Not many photos tonight but it doesn't mean I've not been busy, got my driveshafts from j&r on eBay greased, built up and fitted

Got a type 054 battery, think it's going in the passenger footwell behind a foot rest, so made the foot rest fit and made a strap out of stainless





This will bolt through the floor from underneath, all bits need a bit of padding here and there



Then spent most of Sunday drawing and deciding how to do my air filter

First try was with a k&n filter but looks to big,

[Rosco]

Next is to suit an itg sausage filter over the top, this is what I'm going to do, I've got to make a new fuel rail and a base plate





Std injectors which will fit in the new rail/bracket



This method seems the simplest, easy to make, most compact and uses an off the shelf air filter

Well got all my anodizing back today, looks sweet



Gear shifter



Roll cage bungs, I admit I got carried away with these, but I do love it! Made a bit of a logo with my initials
