I am making my own Ram Air/CAI

[IrishGuyute1]

sorry for the long post.. but i may have a good idea here...
this will be a fun project.. i have devised a way to combine Ram Air technology and CAI technology into a Ram Air/CAI system... will have the best of both systems. essentially take the concept of cars with Ram AIr hoods and relocate the intake duct to the front bumper.. away from the engine bay. i know some people have done this already, but i haven't heard of anyone doing it with the camry. Allot of people are making CAI for the camry but it is less efficient than if you have a Ram air system to force the air through. the filter just sits there, dangling, which is dangerous as it can shake loose and break. this way you can have air flowing at a faster rate, directed through piping to the filterbox which will be replaced by the 98 mustang v6 cone shapped filterbox to help create a more suitable environment for the air flow to continue it's vortex like direction and maintain an appropriate speed into the angine while keeping cool to induce better combustion therefore increasing performance by a certain percentage. Tell me what you think or if you think i am blowing all this through my ass.but i thinkit may be a good idea if someone can do it.... i have no idea if this theory will work tho.. i am thinking there may be trouble after the filterbox because the forced air may lose acceleration once it passes through the filter in addition to it's traveling the long journey through the piping to the box then to the engine.

Its called FMIS(front mount intake system) really but been there done that, gonna manufacture it!!! Check out other threads for help there has been plenty about it. If nothing works for you check out myn once it is in production.

ok.. thanks.. i didn't know that.. how effective is it compared to the other intake systems?

The 'ram air hose' looks like its more restriction than its worth.

ya.. i agree, but i would be making my own.. so i have some say in what i construct it with and how it is made.. i basically want an CAI but i don't like what everyone is doing with just leavintg the filter at the end dangling there. plus i don't see how air is gonna be sucked into the engine by a filter just dangling there. don't you need some way to feed air through the filter?.. i think just letting the engine suck air in by itself is allot of strain and i think it would appreciate a little help from some extra force pushing the air through the filter. Be allot less strain on the engine trying to pull it through on it's own. hehe. and the air just running over the filter is doing not much if it is not going through the filter into the pipe... just my .02

besides that.. hte ramming action would help to force more air into the engine faster, potentially creating a better mixture of air and gas resulting in a healthier explosion and more hp. only con is the extra effort in construcing this contraption. but i think that it would be well worth it. as i understand a few people are trying this FMIS( front mounted injection system) so maybe we will see what the results are when they are finished and post pics... hurry up guys.. i am figety...

im not really sure how much better a ram air + CAI combination would be vs just a CAI. from what silver streak says, only about .3psi is created at 160mph.. it will be less strain on the engine if you force air through the tube, but where will the tube go. if you have to wind it around the battery, fusebox, and headlights there will be quite a few turns- inside the hot engine bay. by the time the air winds around to the filter, it has lost all of its velocity. and by the time it actually gets to the engine, it will be hotter.

if you really want to classify your CAI as a ram air, then heres what i would do. position the CAI with the filter as normal right behind the bumper. then duct another pipe from behind the left bumper opening right to the filter. this way you get max flow from the filter and less curved intake piping. also you get the benefit of colder, more dense air. you might notice a difference at incredibly high speeds, but nothing too big.

i would consider this setup good for the track, but not everyday use. just imagine if you drove in the rain- all that water goes right into your filter-- eek :razz:

You don't need air to be pushed through the filter...the engine produces vacuum to actually suck the air in. However, at WOT, there is virtually no vacuum as the buttefly is fully open and you're taking in as much air as possible...you're car is also running rich in fuel as well...so taking in as much air as possible would be a good thing at WOT.

I really don't think this ram air would make much of a difference, but it definitely wouldn't hurt. The idea of ramming air in into the TB makes sense but really, the filter is a huge restriction...if you have air blowing at your filter at 60 km, how fast do you think
the air would be coming out of it? Definitely not 60km...or even 30 km.....

Again, those ram air hoods on those trans ams only produce .3 psi at 160 MPH!

I did this last year...closed filter in the engine bay with a pipe going to the front of the engine.

Allot of people are making CAI for the camry but it is less efficient than if you have a Ram air system to force the air through. the filter just sits there, dangling, which is dangerous as it can shake loose and break.

I changed from the ram air to cai because the filter was getting extremely dirty...even after a month, the filter had about 3mm of crap on it. I don't see how the filter can break off if it's just dangling there....

i fastened my filter to the car. its connected where the pipe goes to the maf, and the filter is also attached to the car, so it doesnt hang too low or break off for some reason if i hit a huge bump.

ok.. i got the wrong idea about those FMIS then.. but i have heard reports that those filters have cracked or broken with the Short System.. like injen and the such. because the Filter is not really harnessed there.. just left hanging at the end of the pipe. People complained that the filters have been bumping against it's neighbors and cracking.. not particularly injen.. but some brands.

[IrishGuyute1]

So what do you all say i should use for maximum performance with intakes?.. A CAI and throw out the idea of RAm AIR?

[jwa276]

maximum you would be best having the ram air/cai combination. if you ask me though, you probably wont notice a difference.
