I was speaking to someone about running cool air to my cone filter and he was saying that you can get a thing that squirts a mist of meths / water onto the induction cone which cools the air but also conserves your engine by preventing carbon deposits and preventing pre-combustion, although i dont know that i would have pre combustion in a non-turbo car. Ive found a company called aquamist that have a thing that squirts water into the pipe between filter and air intake, no mention of meths though.

Theres a system in the latest revs magazine, connects to the vacuum hose and draws meths into the manifold...
Quite interested myself, I always thought that water mist systems were specific to tubocharged cars though.
The meths cools the air as it goes in and helps give a clean burn, but for what looks like a plastic bottle and a few tubes there asking £300.
Id noticed that all the water inj Id read about refered to forced induction but I just thought a colder air supply would mean denser air supply and higher compression. Im wondering if when Im driving at low speed the induction cone is just sucking in warm air from my engine bay which seems to get pretty hot.
What do you reckon to running an induction pipe from the spce next to the fog lamp for some cool air? (the guy that mentioned meths reckoned this would just get full of muck)
I also read somewhere that the race clios used to use the original filter housing to shield from engine heat and force in air with induction pipes running to the fog lamp holes.
As we all know, turbochargers heat the air as they compress it. By injecting a mist of water into the intake this heat can be reduced. The heat causes the mist to evaporate, which in turn lowers the heat (heat transfer).
On a normally aspirated car the air is not hot enough to evaporate the mist, so the fuel mist mixes with the water mist and the flame does not spread as rapidly as it could do.
This is not to be confused with the intercooler sprays that can be found on such cars as the Evos and Imprezas. This system is a little different.
OK so cool but not moist is the way to go.
Meths tho is a fuel in its self so shouldnt cause much problem with restricting ignition I wouldve thought? the water is also supposed to conduct heat better than air and so makes the combustion more even, whatever difference that might make..
The meths injection system litterally just allows a small amount into the manifold via the vaccuum hose its not controlled by anything other than the engines vacuum. Looks extremely simple for £300 but the i wouldnt fany buggering around with my vac hoses and meths under the bonnet in any kind of homemade set up.
It works on normal aspiration engines.
Well, if we want to get into detail yes it does work on all engines, but the benefits are minimal.
You can use water to cool the charge, simple. This has the benefit of knock resistence (which you really shouldnt be getting in a non boost applcation, if you are your running too hot and too advanced. Anyway, the water will cool and help you control burn. You can gain economy as you can run a leaner ratio instead of the cooling provided by the richer mix. it can save you if you are on teh brink of detonation or pre ig etc etc etc.
If your a real smartarse you can bring the ratio down to stoich.
It also has an intangiable benefit of cleaning. But it takes time, and just make sure no rust forms or say bye bye. lol
Nice one cheers for the info guys. TBH water inj does sound a bit too far. Gonna save up for a PIPERCROSS Viper Induction Kit: http://www.demon-tweeks.co.uk/catalogue/product_detail.asp?PCODE=P/CVFC013&GRP=RP085&PGRP=R010&CLS=ROAD&from=searchhttp://www.demon-tweeks.co.uk/catalogue/product_detail.asp?PCODE=P/CVFC013&GRP=RP085&PGRP=R010&CLS=ROAD&from=search
or BMC CDA: http://www.passionmotorsport.co.uk/BMC5.htmhttp://www.passionmotorsport.co.uk/BMC5.htm
What u reckon?

the easiest option by far, and pretty much garunteed to work, unlike the water spray. Dont know about the Viper but the BMC is worth every penny.
