A lot of you are missing the point of forced air induction, Its all about ramming as much air in as possible, the best way to do it on a standard 240-260 z air box is as i did run the pipe from the heat riser outlet on the bottom of the air filter to a scoop on the bottom of the radiator front mount panel this way you are increasing the actual air inlet capacity 2 x openings instead of 1, i used a piece of large hoover type hose with a home made scoop made from thin steel sheet sprayed the colour of choice, and can guartantee this will make your z both faster and more responsive, just to show how, i was strugling on my 0-60 times because car only went to 55 ish in second so another gear change slowed it down, i did as above and wow car was nearly touching 65 in second and got there faster as well

oh and the cost was nothing i found the hose in a skip also looking at the airbox on the tripple set up above id fabricate another opening underneath just like the old one and use 2 inlets , just an idea
that is what i was trying to do ,i was even thinking about an electric fan to force more air in

finally I made a protection for airfilter in order not to pertubate carbs and for safety of my valves in case of.
Front panel implantation of oil rad and electric fans can take it into account.
Major part of it is behind bumper and license plate... so cooling is as less impacted as possible.
This protection can be altered if tests lead to proove that mixture is OK without it.
We will see thanks to lambda sensor results on road tests.

Sorry but the maths dont work out and it gives you no more than a couple of hp at anything under a stupid miles per hour (see my previous posts for the math)
An L6 on full chat will empty a sealed room of air in a couple of minutes....... 100mph of air in an 80mm diameter pipe doesnt even come close to increasing the air requirements.Look at it this way if you stuck a jam jar with a pressure gauge in it, out of the window at 100 mph what would the pressure reading (above atmospheric) be.....about 1 psi....QED
What sort of pressure do you think even a very mild turbo supplies....try 10psi...if you can get that with a fan or ram air then the physics rule book needs re writing
The air box's biggest advantage is feeding cool(er) air into an engine bay that runs close to 60 degrees duhhhh!
next advantage is the reflected pulse issue with plain air horns
BTW no need to shield the filter but it looks good.
