Re: Cold air feed for standard airbox

My current ram air system, just working on keeping the bonnet shut.
I did this on a Honda 90 about 30 years ago, the engine got a staple diet of flies, and a weak mixture just to make things worse .

Re: Cold air feed for standard airbox

Holy Zombie Thread revival Batman ! If you run a 1.1 Eco( especially -or any 1.1/1.2 Panda) , gutting the plastic 'walls' / 'dividers' inside the air box and cutting away the blanking plate ( seriously Fiat ?!) behind the perforated air intake in bumper help greatly in throttle response / acceleration ( and probably mpg at a steady cruise ) .Just be very careful you don't leave any plastic debris/ dust in these to get sucked into intake ( use good strong Stanley knife , hacksaw blade/ sander / sandpaper , Hoover etc to get the job done ) The obvious fear of increased likelihood of water getting in doesn't seem to have materialised despite lots of motorway journies behind lorries in torrential rain and driving through floods etc .Fiat really strangled the lovely old 1108cc FIRE engine in the Eco taking about 2 seconds off 0-60 time with this nonsense .Of course they went to far with the Fiat 500 1.2 but that's another forum !

Modifying the airbox will make absolutely no difference whatsoever to performance, acceleration or economy except when the engine is running at wide open throttle, so cruise mpg won't change at all (unless you cruise flat out!).

Quite agree - it probably sounds more urgent though.

I was working on assumption that if car could go faster or had a tiny bit more bhp it would use less fuel at same speed .Then again I guess using that logic Ferraris would get 100 mpg

Think about it; the ECU controls the amount of fuel injected according to the amount of air that's flowing into the engine (OK, it's a bit more complex than that, but it'll suffice to illustrate the point). Except when the throttle is wide open, the air flowing into the engine is restricted by the butterfly valve (that's how the power output from the engine is controlled) and will be less than the airbox system is capable of delivering. Improving airflow through the airbox just means the butterfly valve doesn't need to open so much for any given airflow through the engine; the airflow needed for any given power output remains the same, so the fuel injected will be the same as well. It's only when the butterfly valve is fully open that improving breathing through the airbox will increase the absolute power available.
