Never see a design like that but its working along the same lines as an intercooler basically.

Heat expands things and cold contracts them, so cool the air intake charge down then the air within that charge contracts therefore you can fit more air into the engine. The more air the faster the car goes (Turbo) but you must have the correct amount of fuel to match the increased air think

so its taking the induction kit a stage further, wot sort of mods would compliment this, how would i increase the fuel, ps this aint the saxo

would tis have to be a turbo'd engine
wot a bout a supercharger, or a na engine

kinda, just cooling the intake charge down just as an intercooler or a cold air feed would.

More fuel could be obtained by either fitting a Power Boost Valve and increasing the fuel pressure or by replacing the fuel injectors with larger injectors think

RRFPR (rising rate fuel pressure regulater), bigger or better fuel pump, larger capacity injectors, and an air/fuel ratio gauge to make sure your not running lean which will lead to the engine going pop eek

Looks as if it says it works on all engines but doesnt mention derv's. Not heard anything about it before so wouldn't put it on my car until i've seen it proven on others first to be honest, would rather spend the money on other engine mod's that dont need re-filling smile

so from you are saying is that if you increase the air, you increase the fuel, which i know, but surely its not going to alter the mix as much as the intial change from manufacturers air box to induction kit

This sounds like a good mod on a turbo'd motor as they run higher inlet temps. A 1.6NA engine however wont really react much to this as the intake air temp is a lot lower anyway as the air isnt boosted to incredible pressures/tempuratures. However if it can lower the inlet temp to really low levels you get a lot more O2 in your chambers thus giving you a more powerful bang. Up the fuel to match by doing a re-map or as said before bigger injectors,boost valves etc and u get more gogo. All this will increase compression though and high compression gets you to the realms of needin stronger internals to prevent your rods shootin through the bottom end.

See how much BHP gain it gives then if its good think about it

Increasing the volume of air does not automatically increase the fuel. To increase the fuel you need to either increase the fuel pressure to force more fuel through the origonal injectors or upgrade the injectors to allow more fuel in....

More and and fuel makes a bigger and more powerfull explosion in the combustion chamber therefore giving your car more power.....

It's a bit of 'overegging the pudding', air speeding through a cold bit of pipe will not dramatically increase the amount of volume for fuel vapour to ignite and expand. I wonder if it'd actually make any noticable difference.

Cold air feeds seem to be the trend at the moment.

but wot i was saying is there is a massive difference in the amount of air when you change from the orginal airbox to an induction, but no one alters the fuel amount

Not really fella no, the air is a little colder,less restricted and theres more O2 particles as it is denser, the change is so little that ur MS sensor detects the air and adjust fuelling to compensate. Forced air however goes outside the tolerance of the MAS so the ECU needs mapping to add EVEN more fuel. Also injectors and pumps nee upratin if ur crammin crazy levels of air in. U done need a re-map just cos u put a 57i on. No way. U wud see no REAL power increase and it deffo wont run lean

Cone filters only add more problems, if you look where they're mounted, right next to the exhaust manifold, nothing but hot air goes in.
I've always wondered on the length of the tubing from the plenum to the filter, can it be too long?

One thing ive noticed on the 1.6 is that my standard intake starts behind the headlight with the airbox.Through the MAf then onto the rocker cover and up to the Throttle body. I leant on the intake tract above the rocker cover and scalded myself. How hot must the air in there be???? jesud christ. Think ill reshape my hosing when i get my BMC CDA to keep the pipe away from the engine. Or get a scoop to cover the rocker cover in cool air?? that was a joke. No more scoops for me until i get me scooby. Cossie vents a maybe though

I cant see this kit doing anything negitive to the cars performance smile

The cooler the intake charge, the more performance you will get.

As for cold air feeds, on an N/A car, a ram air induction kit / cold air feed is the best. N/A cars increase in vacume as the engine revs, and if you can reduce this pressure so the engine is relying less on "Sucking" then its always a good thing.

Ive always wondered about cold air feeds on turbo cars because as soon as the air hits the turbo it gets heated via a heat sink from the hot side of the turbo to the cold side, and gets warm anyway - the intercooler is the best way of then cooling the charge down. However, again, a cold air box, where you can maybe generate a little +ve pressure before the turbo from the car moving would put less strain on the turbo and help it work a little more efficiently, though I guess youd need a good size scoop and be doing a good bit of speed to generate some +ve pressure due to the amount of air the turbo can suck in.
