OMG ! , it made a small difference !

Cheers fellas , oh i also forgot to mention before the drop in temperature in the airbox ( i've had a thermometer gaffa taped inside the airbox the last few days while testing ) . With the pipes sucking air from behind the lights i managed to lower the airbox temp by around roughlly 8 degrees ( nearlly nothing of a night with the lights on ! , the lights seemed to heat the air to much behind the lights when they were on) , since moving the extra 2 intake pipes to behind the grill next to the scoop it has dropped about another 6 degrees , total now of roughly 14 degrees cooler in the airbox than standard, and not effected by the heat from the headlights of a night no more.

What's the expected outcome of this cooler air do you think? If the air is cooler, isn't it denser? Would this affect mixture in any way do you think?

I don't know much about this really, just thinking out aloud!

The outcome of the cooler air is the above advantages i mentioned i have gained , slight increase in power in the lower rev range and also much better fuel consumption. Drive your car on a cold morning and compare it to driving it on a hot afternoon , u'de get the idea of the effects gained sorta ;) . As far as the mixture , it remains the same , just now that it can get the air a little easier and faster it allows it to mix more air and fuel a tadd faster ( at the same ratio though as standard ) giving the better throttle response . ;) ,
also it's been noted in the past that cooler air has a better combustion ,
hope this explains it a bit for ya , i tried to keep the explination as simple as possible , bit more to it really but thats the general idea ;) .

The colder & therefor The denser the air, the more Oxygen particles in there for the same volume of air. Fire needs 3 things, Oxygen, a fuel source & an ignition source. Oxygen is a very very flamable substance, the more oxygen in the cylinder the more efficient combustion, & Better & bigger the bang, therefore more power, but also reguires less energy due to a much more efficient fuel burn, and therefore a saving in economy.

Or so is my understanding of it.

As XR6-VCT-2000 stated above, take your car for a spin in the cold air of the night, or very early in the morning in cold/dense air, as apposed to in the afternoon in much warmer air conditions, and you will be able to feel the difference in performance between the two.

Spot on ;) .

Thanks for the short Science lessons fellas!

I'm aware of the car running much better in the cooler air, motorbike as well, just wondering what some of the science behind it was.

Cheers,
