can someone please educate me on air induction systems... i would like to kno the +'s and -'s of these 2 different types of systems... thanks

Short ram are cheaper, and the tube is shorter.

Cold air is more expensive, and provides more power than short ram.

cold air all the way.....with a nice heat sheild. serch for heat sheilds there are some really nice ones on here

I would say mount the filter IN FRONT of the radiator (but tucked away up high, near the hood, behind bumper skin) that area gets alot of air.

That or have a shorter intake setup (in engine bay heat) with a heat shield built around it.

WTF is "short ram"?

Making sure then engine only breathes cold air from outside the engine bay increases power and reduces the chances of detonation.

A pod filter sucking hot (140+degF) engine bay air is basically throwing away free power and negates most of the gains from replacing the airbox with a pod filter.

Cheaper intake for Hondas, it just replaces the plastic tube with metal and a cone filter.

What's "ram" about that?

bigtymer

is there really a point of getting a heat shield for a cold air system? isnt it unecessary considering the cold air intake already prevents heat from getting in?

pinkfloyd

it helps the heat from the engien getting into the cone filter. so it only gets cold air. search for heat sheild. you will learn a lot and quick. i dotn even have my car running but i plan on makeing one soon because it is cheep and works well.

NZConvertible

Without a heat shield it is not a cold-air "system". The whole idea is to provide outside air to the filter and prevent hot engine bay air from entering. You have to do both or it won't work.

5 point whoa

the ram air is were it just pulls all of the air in, not just cold air, it supposevely is supposed to get more air, but it's hot and pintless

Check our the link in my signiature. True Cold Air no heat shields no "ram" just power and safer i.e.(no detonation)

BTW NZ- The engine bay in my car has been at 180* F I have seen it go higher when it heat soaks.

No cold air intake, means that the engine is only sucking in cold air. It doesnt matter how its setup, heat shield or not. Some people dont want to have to clean or buy a new filter every 5K miles.

it is a good idea to get cold air,so i would build a shorter setup with a heat shield. reason being, you actually loose low end torque(which we lack anyways)with a longer tube. either way they are better than the stock airbox.

A true "ram air" intake has a forward-facing inlet that is pressurised by the forward motion of the car. Anything else is not ram air.

A true "cold air" intake is one that can only such air from outside the hot engine bay. Anything else is not a cold air intake.

These are simple concepts, but the names are constantly misused by people flogging shitty products and kids who don't know better.

Hey NZ I was thinking about buying a manometer gauge. Do you think its worth 60 bucks? or should I rely on my home made manometer?

Wankel7

Your homemade manometer will be as accurate or more accurate than a Dywer Gauge man.

bigtymer, go read this artical on the Autospeed website. If you understand this artical and know what is going on. I can guess you will know more about intakes and how to make a good one than 80% of this forum.

What he said. A gauge is more convenient, but I wouldn't pay $60 for it. Scrounge for a 2nd-hand one if you really want one.
