Air Intake Setup's pros/cons

    Recently i found out that i have crack in my air intake piping, so i figured i might as well try some of the intake modifications that ive read about on this site. I was wondering if anyone had any opinion on which system is better at bringing cold air to you filter.

    Im leaning more towards the DSM-like setup, with the filter behind the front fender simply because it looks like the easiest, cheapest, and most effective of the different setups. I would still like to know what you guys have tried out and found to be the most effective.

    i was also considering what kind of change an large hood vent like the Carlos Sainz would do to engine bay temperatures, verses some of the custom vents around here such as Mafix's Nemesis or rye's Ice Racer.

    Edit: Put this in the wrong section, could someone move it please

    i dont know how effective but i built a short ram with mandrel bent tubing from summit and then surrounded it with aluminum walls [ceramic coated] around the cone filter and then re route the battery to the trunk ..or boot for you canadians.

    ~I think this is just as good as a CAI that would suck air from the bottom of the engine bay..if not better because of the lack of bends

    ^ plus you don't need the bypass if you drive in heavier rain.


    and it's the Brits that call it the boot.

    As far as the stock hose, they're like $100 new. However, Kiasis is grabbing one from the junk yard it it will be up for sale soon.

    You have one other alternative, buy a K'nN high flow stock box filter and the flow won't be as restrictive.

    As for a cai or short ram, I can't think of any drawbacks to a full cai, just a bit more $ than a shortram. For the gains to money spent, I don't really think it's worth it. For short rams, I think mine does suck some engine bay air in but, I haven't noticed any negative effects. The whole concept is to get more colder air into the engine to achieve better combustion thus adding torque, HP. I might've increased HP alittle, can't really tell. I have noticed a bit more torque though. Def. makes the engine sound more beefy.

    When we built Mafix's hood all those years ago(its been a while) he said he noticed some under the hood temp differences. They do help, I know that much, but to what degree? we've never measured.

    I found my engine ran a little cooler with the vent, but only when pushing the car. Under normal driving condtions it doesn't really do anything but look cool haha... (unless you have a tmic)

    What im looking to do is create small horsepower gains, and extending the life of the car overall by making the induction system smother and more efficient. Im not sure that the cost of custom fabricating a box or setting up a short ram is justified verses the gains made. Thats what im trying to determine here and any other system people are using to make induction more efficient.

    The short ram idea seems good to me, only problem is that im trying to figure out what the difference between the Short Ram and CAI systems are? Whats its advantaged/disadvantages to a Cold Air Intake? (BTW im still a noob at this so dont give me too hard of a time) :)

    I was also interested in installing some sort of hood vent because the more i learn about my car and all trac's of this generation, it seems like a lot of the issues come from having too much heat built up underneath the hood. I think eventually im going to go with the Carlos Sainz RC vent simply because it looks like it would be the most efficient at getting heat created by the turbo away from the rest of the engine. Any thoughts?

    Start with the short ram and go from there. Maf adapter and "cone" filter.

    If you're putting on a cai....you'll need to redo the exhaust if you want to see any hp gains....

    I plan to do that eventually as well, this is just the first step, so to speak. Basically i know how thing are meant to work in theory, i just have little real world experience, thats why im asking you guys. I plan on gutting the secondary cats at the very least later on, but thats not really what this thread is about so....

    Don't know if you saw what I did, but it's somewhat unique. If you have a 'trac it would look obviously different, but the concept would still be the same.
    Removed stock side duct and replaced with aftermarket acordion duct wich runs from filter to front headlight area. If you go with a scoop, a similar approach could be taken to rout some of that air directly to intake filter.

    technically, the Celica already has a "cold air intake." what I think would work best would be to replace the stock plastic tubing with metal, and have the front piece come a little lower down. then put a cone or mushroom filter onto a MAF adapter, and build a box around that. this way, the air you're sucking in is from outside the engine bay, but if you're running i rain or deep puddles, you dont have to worry about hydrolock.

    What i don't understand about the vast majority of all trac CAI's is the removal of the battery. It looks like it makes a bit of room in the engine bay but i think you could still custom fit your own box in the stock location. It is to improve the intake airflow by using a straight pipe, instead of the bend in the stock pipe, and does this location really give you cold air that much faster then the traditional location?

    will on your trac you'll want to do the batter relocation first, then the straight intake mod with a cone filter. NO CAI.

    Turbo doesnt need a CAI... the air is going through a turbo... whats the point of sucking in cold air if you're gonna heat it up and attempt to cool it off?

    I have an adapter plate and extension cable for a 165 AFM if you're interested $25 shipped if you live in the states...

    Ok, i see your point. The inter cooler would cool off any air sucked into the intake through the turbo so a CAI would be redundant. Im still curious about the box concept though it seems that everyone with an All trac custom intake setup insists on building your own box around the air filter. Is there really any point to enclosing the filter if the intake temperature effectively dosen't matter on turbo charged engines?

    The cooler air concept still stands to some point even with a turbo engine. If they can continue to pull outside air through their intake its still gonna take a longer exposure to the turbo to heat it up. Aside from that, it always looks alot cleaner in the engine bay to have a box instead of a dirty grungie filter hanging there and it also provides some nice large flat surfaces for mounting other items.

    Its a good idea to close it off, but only to keep stuff away from it, for the most part it gives you lower temps before entry

    you will overall have cooler air but since it hits the turbo it wont be a benefit that you'll notice... Mostly it looks purdy and keeps the filter cleaner longer because less engine bay debris is getting into the filter...

    Alright, so basically a box is designed to keep the air filer cleaner for longer and provide a bit of colder air to the filter by isolating it from the rest from the engine bay. Do you just leave open the side of the box that faces the head light's in order to suck in outside air, or do you use some kind of hose attached to the box to do that?

    Could you just use some exhaust piping and weld/drill adapters for the PVC and Idle hoses?
