But its a good idea to secure (doubleside taped) the sunvisor thou.
No, if your theroy was correct then we would be using sunshields on the outside of windscreens not on the inside 8O

The heat travels through the side of your box then is reflected back by the sunviser, it is regardless what side the sunvisor is on.

theres people putting sunvisor on the outside too. but most people dont do that is becos it might get damaged by external elements or most probably get stolen. :lol:

Ya it doesnt really matter, as i've explained earlier.

the sunvisor trick works but if i was to use it, it would only be temporary. I think an enclosed box is still ideal.

the whole point is a enclosed box WITH a sunvisor.

Dude people steel p plates and dust caps, as if they would think twise about nicking it... 5 mins in a public car park... hell 5 mins outside your house and some kid would get hot

do people really do that? 8O

haha.. you were previously talking about putting on the outside windscreen. now that will get stolen by some lowlife.

woops my mistake... didnt realise that until i took a second look, but i guess if the box is enclosed and efficiently made, you wouldnt need a sunvisor aye

No, it depends what you make it out of. If you make it out of a metal then it will conduct heat and if theres no insulation you will increase the temp inside the box.

Plastic doesnt conduct heat like metal but is harded than metal to make a box out of.

I personally reckon that it's a lot more important whether the box is airtight or not.

If the box doesn't let air in from the engine bay, doesn't matter squat what it's made out of.

yeah but how often do you see an airbox made out of metal, im talking of a regular oem out of the factory air box made from the usual array of composite plastics. Go to any wreckers and grab a suitable sized airbox from any car, that in my opnion would be a good start. I have no idea where you got a metal airbox idea from. Heat shields and airboxes are two different things but they can work together to make the cai system more efficient.

Try and fit a pod filter into a OEM box.... good luck mate 8O .

Im not going to explain the fundamentals of a CAI to you as we have repeated this conversion many times before.

do your self a favour and a do a search

who said anything about a pod filter :) , unless your going for a look, high flow panel filters are the way to go. i know the workings of a cai, im studying engineering at uni and did thermodynamics last semester. Im not protesting the fundamentals of a CAI. I just think that the sunvisor idea isnt something thats really worthwhile, if you grab an airbox off a larger engine car, im sure a pod would fit snuggly into it, if not find another suitably sized box, its called ingenuity. :idea:

8O Where do i start

Mate you should seriously re consider your uni degree if you think panel filters are the way to go.

And the winner (the HKS) didnt even have the full benefit of a heatsheild or encloser or cai

I have not only personanly tested the sunvisor idea (and it worked unbelievably) so have race cars.......

Just cause something works in theroy, doesnt mean it does in the real world.

Hmmm, im sure you at least know that pod filters drawing those results wont get 8 hp gains like that hks did without having a cai setup of some sort. Most will agree that pod filters in general are mostly for looks and a cool induction noise UNTIL you direct cooler air into their intakes (otherwise they would be sucking in hot air, isnt it true?) While the hks is an impressive piece of kit, it must have a well ventilated path for air to travel through to it. Here is an interesting post made on the pulsar australia forums regarding a pod vs panel comparison on an sr20.

it flows better as it doesn't filter as much, amazing.

air filters are for filtering air hence the name therefore you need to look for flow and filtration combination. In addition on most of thise tests are dont with the bonnet up and a big fan infront, no heat soak. Also just cos it was on the net, doesn't mean it was accurate.

As for metal CAI boxes, you know aluminum is a great conductor of energy including heat? Under a long drive, I would love to see the heat soaked temp inside the box, plastic, thick plastic is best - hence why they are always plastic. Thats why the UAS kit is great, its very thick rubber pipe

Doing Used Oil Analysis has seen plenty of extra sh*t in your oil after prolonged use of the top flowing pods. Globally this has been seen many times on many cars. Comparing race cars to ours is pointless also, they usually rebuild them after a few races so the same issues generally dont apply.

As for Nick and his pressure comment, he is 100% correct. A sealed box maintains or can increase pressure with the right intake, after all you want maximum pressure being pushed into this is especially true at speed ad will cancel out on flow restrictions of a filter.

I have a sealed stock box with an extra feed from the front bar + UAS intake pipe and K&N high flow pannel which gives me best combo of filtration, flow and heat prevention while keeping the pressur loss to a minimum...I also find that throlle responce is better, especially smooth at low revs and speeds.

I was one of the ones to actually suggest the sun reflection material, do a search and it looks pretty *~delightful!~* but does have an effect

I have tried all the rest and this is the best for real world driving conditions. This includes KN, UniFilter, the sun stuff, shields and they dont compare to the setup I have now.
