not on a Maser, no... but on many other cars yes. As long as the MAF stays in it's original position it should behave fine.

The induction system will be designed to work with varying rates of flow and temperature bandwidths considering it needs to work in all climates and with air filters that flow freely from new and become restricted after prolonged use.

JDM,
Inductions kits are fine, but you do need a cold air supply to keep sufficient oxygen going to the air intakes. The Maser engines should not actually need induction due to the size, they have a heck of a suction on them, but they do need oxygen from cold air, hot air would not give good take off speeds, or performance.

hodroyd, the cold air feed would affect air density rather than oxygen levels, increased altitude is where oxygen levels drop and affect performance. Hot or cold, oxygen levels are consistent.

a cold air feed would not stop heat soak, and would only come into play at crazy speeds so I see it being pretty ineffective on a naturally aspirated car with an induction kit fitted to it.

JDM,
Sorry mate I did not explain that very well. I meant that cold air has of course a higher density, which due to that has higher oxygen levels being more dense. In hot air the air is less dense, ie from an engine bay and therefore has less oxygen due to the lack of density. Density is the amount of molecules, including oxygen that are packed in to a given area. In a hotter environment it feels harder to breath than when in a cold environment, all due to the lesser amount of oxygen in a hotter environment.

trusay hodroyd :) What we need to do is some real world tests. Your theory is spot on, but in practice it doesn't always work like that.

Cold air feeds are more worthwhile on naturally aspirated cars for sure. It used to grind my gears when people went to extra efforts to run cold air feeds on turbo'd cars, when the induction runs through a 800 degree celcius turbo anyway, only to be intercooled afterwards. The effect of running air a few degrees cooler only for it be super heated by a turbo anyway proved ineffective after running tests with ACT (air charge temperature) gauges.

JDM,
I agree and no the world is not perfect, wish it was. I think we all still have to play about with these ideas and maybe use some unconventional thinking to arrive at what we want. I am going to try and have an in depth look at the intake configuration on my 4200 and see where we can go with this, maybe play with some bits and bobs. Eventually somebody will say...EUREKA...!!!!
