Cai

[lovemylantra]

:D ... Finanlly recieved my EVOFUSION CAI, i hadda wait till today since yesterday was real crumby. It took about almost 4 weeks to get here but well worth the wait. now i can replace the SRI and in a week or 2 its the catback next :D ... Im gonna take pictures once its in

i cant believe it ... after waiting a month ... they send me one riight pipe and one wrong one lol its unbelievable how someone can screw something up like that. now i have to wait again for them to recieve and send me another one cause of some dumba$$ at the warehouse ... i was so pissed .. 2 hours into workin on my car when everythings ready to be installed i look at the pipe and realize wow this aint gonna fit lol ... so i hadda put it all back together and now its more waiting :mad:

[smileymattj]

cause of some dumba$$

lol its always a dumb one, why can't it be a smarta$$ that just done it to piss you off, lol.:hammer:

[Whipper]

wow man, that sucks

[Munky]

What's wrong with it? Wrong diameter, or wrong length?

[Cypher]

Post up the pics. I had the EF cai on my car for 2.5 years.

[lovemylantra]

the longer of the two pipes that connects to the throttle body doesnt curve the right way under the fuse box so i can connect it to the smaller pipe. instead of curvin riight it curves up

What's wrong with it? Wrong diameter, or wrong length?

[j0hnh0lmes]

o.0 maybe try turning the pipe.....

[Qyn]

o.0 maybe try turning the pipe.....

I'd hope he'd tried that...

[Munky]

I'm with Jim. Post some pictures up, we might be able to help you make it work without having to send it back.

[lovemylantra]

i highly doubt it i tried every combination there was ... but heres some pics ... see how the main pipe curves directly up instead of riight

where's the picture??

[lovemylantra]

i cant upload the pics because there too big and i dont know how to resize them so ... $h*t

if you wanna see what the intake looks like i guess personal message me and i can email them to you

see how the longer of the pipes curves directly up instead of to the riight ... i flipped the pipes in every which direction and it still wouldnt fit

got it!!!!!!!!

[hyunelan2]

Looking at the DIY from the Accord CAI, the pieces probably won't be exactly the same. Just thinking about the shapes, it seems like this would work (see attached)

I say Bender had something to do with that. :eek:

[lovemylantra]

it looks like it could work but im almost positive ive already tried that configuration ... but ill try it again and see what it looks like and if not im just going to get the riight one from evofusion instead of trying to fit the wrong one

[hyunelan2]

How do you know you have the wrong one though? They might send you an exact duplicate of what you already have, because it's correct, just supposed to go in a slightly different method than you've tried. Have you looked for any installed pics of the EF CAI in an Elantra or 2.0L Tib?

[lovemylantra]

nope wrong angle wrong bend .... back to waiting ... hopefully it doesnt take EVOFUSION another 4 weeks to ship me this one

[SilverElantra]

doesnt that intake drop down to the left of the battery and not go behind the battery tray/under fuse box... could have sworn that one was different. try seeing if it will drop down to the left of the battery behind the radiator.

[lovemylantra]

not the evofusion CAI but ive seen how full intakes go and the way this pipe is bent is doesnt work. i tried it yesterday the exact same way and no luck. and believe me installing this intake isnt any different .. ive already dremmeled where the resonator used to be and the pipe thats supposed to bend underneath the fuse box sticks out to far and will restrict me from putting my battery back in snug, unless i relocate my battery but im sure thats a pain in my @$$

i could be wrong but on the evofusion website they have a DIY on the intake install and they show the intake behind the fuse box

[NY2002ElantraGT]

heres a question.... would the problem be maybe it fits maf based and not map? since there is a little extra length with the maf

[lovemylantra]

my car is xd (2003) ...

[hyunelan2]

Right, could it be that the CAI is made to work with the MAF based 04-06 cars, and not the 01-03? Does anyone have an EF CAI on their 01-03?

EDIT: it appears there are 2 different ones, one for 01-03, one for 04-06:
http://www.evofusionusa.com/TeamSR/Hyundai/01elantra-intake.html

[SilverElantra]

that was my next question.

[lovemylantra]

i didnt make the wrong purchase so it has to be the fault of evofusion

[NY2002ElantraGT]

im gonna have him come over saturday and i'll take a look at it, i'll see if i can get it to fit.

ok looking at the picture you posted that is an 04-06 intake

here is the 01-03 intake:

http://www.evofusionusa.com/TeamSR/Hyundai/01elantra-intake.html

the curves are completely different. EF messes up yet again!

[lovemylantra]

EVOFUSION is a big pain in my @$$ lol ... not only have i been waiting on the catback exhaust from them since early april, now i have to send back this intake because of the incompitent people they have working at their warehouse that doesnt understand the difference between 01-03 and 04-06 lol .. awesome customer service

[xdforme22]

Well, you can't say that no one has warned about EF.

[Cypher]

if its just a mess up between the maf and the map based versions it should be easy enough to fix. The EF cai fits perfectly down in the fender below the battery.

[lovemylantra]

this is what they did lol ... absolutely ignorant ... the dude i talked to on the evofusion screen name said i was one of the few people to order that intake in the last couple months ... so i dont see how if that was the case how they could possibly screw up this order so bad lol ... they sent me the 2 couplers and 4 clamps which is for the 01-03 setup and the 04-06 piping mixed together

EvoFusion screwing up...SHOCKING

[lovemylantra]

guess now i know not to order anything else from EF .. who knows what theyd ship me lol ... thank god i didnt order headers or anything else ... the dude also said the exhausts are in the country so i dont know what that means but im assuming i should be getting that pretty soon i hope, and HOPEFULLY its the right exhaust otherwise im gonna flip out lol

EvoFusion screwing up...SHOCKING

[SilverElantra]

i have not really had any of the problems many state to have with evofusion. ya my bumper took forever it seemed, but it was so worth the wait, cause now its just sitting in my garage till i get money anyways lol.

[cbogg]

but you're still one of what 2 people right now that I know of with a tib bumper? so still awesome.

[SilverElantra]

lol ya i know isnt it, anyways back on topic. just try to bend the intake in different ways, possibly attaching the other pipe to the throttle body, and just see if there is ANY way to get it to work, otherwise, just wait on evofusion.

[NY2002ElantraGT]

i might give it a shot for him saturday, i know exactly what would make this fit.... to simulate the space of the MAF sensor, just get a Bypass filter.... actually i can get one from my friend for you, $10 i think i sold it to him, he is selling his CAI so i can grab it for you. theres a meet in Nassau this saturday we can all go to the meet and do it there!

[Qyn]

Just cut a hole in the hood.

[SilverElantra]

ya snorkel style.

[lovemylantra]

thats crazy im not gonna do extra work over the wrong intake lol i already took pics and sent it back to evofusion and they told me the top half they sent is for a KIA RIO not elantra thats why it would not fit ... there shipping me the right top half asap :D

Just cut a hole in the hood.

[2003GT]

Anybody tried some Ram air setups. that Hole in hood idea sounds pretty good to me. BOB

[Qyn]

I was joking... ram scoops on our cars look like ****e.

[2003GT]

Ya but what about any Ram air setups like on a WRX or like under in the fog wells or something. BOB

[hyundaiLKsunday]

I thought I saw a thread on this a while back, and they determined you wouldn't really gain any benefits from it (ram air), at least with the amount of power out engines put out.

Plus the hood scoop on the subies is for the intercooler...not ram air.

[RotaMan99]

I thought I saw a thread on this a while back, and they determined you wouldn't really gain any benefits from it (ram air), at least with the amount of power out engines put out.

Where ever you read that its a bunch of BS. :rolleyes:. Ram air setups, if they are not very convoluded, will increase the pressure in the intake system and you could get an extra 2-4 psi or more from a ram air setup. Regaurdless of how much power our engines make, that extra pressure can increase it.

[moonlite5hadow]

wow... thats all im gonna say about it...

but looks like im not ordering this CAI after reading this thread!
This vertical brake line coming off my brake booster is really fxing things up in terms of CAI, and im getting sick of having my intake sandwiched between by hood and battery. the EF 01-03 CAI looks like it bends correctly to get around it, but i dont know if i wanna deal with EF...

[lovemylantra]

i honestly dont blame you lol ... EF is a pain ... making mistakes on simple orders like mine and then their company makes the serious errors ... like with the catback exhaust order ... how do you send 20K worth of the wrong exhausts?!!?

wow... thats all im gonna say about it...

[2003GT]

I know the hood scoop is for the inter cooler. But under the hood there is ducting like on the old Z28s or the Pontiac Ram air set ups. I just bought a cone and am wondering if I should run a feed to it from in the fog wells. BOB

[Qyn]

You'll have to clean the filter more often with the cone in the wells, dirt loves to get in there.

[2003GT]

I would keep the cone up in the wells but run a hose out of the front of the filter, it has a second filter in the front of it, and run that into the wells. Go to the Thread Air filters to see a pic of it. BOB

[RotaMan99]

Wouldn't be worth the trouble. All the extra pressure could equalizethe intake and than come out the sides of the filter. Besides, that little filter element on the nose of the cone would be very restrictive for any usable pressure.

Ram air needs to be a completly sealed intake system for it to function correctly.

[2003GT]

Ohh ok thanks. BOB

[RotaMan99]

You could probubly make something with those cone heat shields that go around the entire filter. I don't know how well they seal but maybe add a large flexible hose to the front of one of them.

I wouldn't do this simply because it would look tacky but if its designed and placed right and should perform good.

[Munky]

Function over form, right? ;)

[2003GT]

Thats kinda of the reason of the New K&N Apollo CAI. I think. BOB

[RotaMan99]

Ya I do like the design on the Apollo intake. Although you still have to keep in find, especially with ribbed hosing, is that the less bends or better yet, the less hard bends the better. I don't know what the restriction factor would be on say a 45 degree bend with that tubing but I probubly would try not to exceed that degree.

If I was going to do any intake on the car, I think the Apollo would be something I would look into. Only if I could get a good straight shot to the nose of the vehical where high pressure is present.

Function over form, right?
lol. A Little bit. I like to make things look nice and clean but work is intended. Lots of thinking comes first.

I don't know if I ever posted pictures of the intake I made for my Rx7 but thats the type of work I like to do and the thought process that I go with.

[SilverElantra]

^^^ so post a picture, duh....

[RotaMan99]

Sorry, I didn't want to post it again if I already did and especially in someone elses thread. Here is a link to it. The filter is an Amsoil air filter.

[SilverElantra]

so with the way you did it, it sits in front of the radiator? This is how you were able to achieve positive pressure? How is this any different than putting it in the fog light hole?

[RotaMan99]

I havn't said anything about the fog light hole since I have not looked at it enough to see how effective it would be.

That intake is in a positive pressure zone but its not really a "ram air" setup but it does help with the pressure loses through the intake its self.

[lovemylantra]

the fog light hole i think would be just as good its lower and away from the engine ... cooler denser air

[RotaMan99]

Having it being lower wouldn't have anything to do with how it functions infact it could be worse. You can put the intake right in front of the rad like I did and at speeds it will never see warmer than ambiant air. Not saying this is the best place, just saying with the high air flow on the front of the nose, the intake would never see warmer than ambiant.

Just seems its a longer run to the fog light duct and you would have to make a couple 90* Bends with ribbed hosing which wouldn't be very good. Although it may function as desired, say it be a ram air setup, it won't be as efficiant as it could be.

I havn't taken a close look but it seems we run into the same issue I had with the rx7 with where and how to run the tubing since there are no large "gaps" to do so.

[NY2002ElantraGT]

also realize the lower you go, the greater the risk you run of Hydrolocking your motor. a Bypass filter is highly suggested with a CAI.

[lovemylantra]

thats why i went out and bought one for it so this doesnt happen .. thanks =D

[RotaMan99]

Bypass valves would only work if the intake is submerged to the point to cause excessive restriction which would cause lots of vacuum to be pressent in the intake.

Bypass valves are introduced to intakes TOO often when they don't need to be. Driving in the rain, unless your filter is directly in the path of the rain and will get SOAKED, you don't need to worry. This is where the "thinking" process comes in to place the filter where it will be safe.

Are you saying on ANY CAI? If so thats not true but its the paranoia that makes it believed to be fact.

[lovemylantra]

better safe then sorry!!

[RotaMan99]

Thats fine.

Infact. To revise my last post. Even if the filter got wet you would still be perfectly fine. People use water mist injection all the time. You need a good amount of water to lock the motor. There is still space with the piston reachs TDC.

I just want EVERYONE to know that you don't NEED a Air Bypass Valve when you have a CAI.

[2003GT]

Why would you ever inject water into your motor. BOB

[SilverElantra]

cooler denser air.

[KeWLKaT]

Actually it's to simulate a higher octane (i.e. no detonation) on high boosting vehicles with little to no intercooling.

[2003GT]

Oh ok I thought you were trying to steam clean it. :) BOB

[RotaMan99]

Edited....

It will aid in keeping the intake charge cool thus reducing detonation. Has nothing to do with octane rating. Its a very very fine mist that you spray only above a certain RPM and while at WOT. Water is not BAD for an engine but to much is. To much is what hydro locks a motor. A little bit of water is fine. In fact. you could take a soda bottle and fill it with water, put a vacuum line in it with a small valve to keep the water flow slow and you can steam clean the internal combustion chambers.

[2003GT]

Would this be beneficial to anything. BOB

[RotaMan99]

Not to you or I. If you were boosting it would help.

[2003GT]

K. Bob

[RotaMan99]

HEre is a blurp from a site im linking to

How does water injection work ? It uses water that you store in a tank (or your windshield cleaner reservoir) in your trunk, or under the hood. It then uses a pump to pressurize the water, and whenever the boost pressure sensor senses boost (varies from 5 psi, to 15 psi, you select it by rotating a dial on the sensor) it will begin to spray the very fine water mist. This very fine water mist evaporates, and lowers the intake charge by absorbing the higher temperatures inside the intake manifold, and the head and helps cool the engine.

http://www.modernperformance.com/all/water_inj/water_injection.shtml

I made bold which is VERY important to understand how the water injection lowers the intake temps.

When water evaporates it needs to consume the energy (heat) around it which lowers the intake temp.

You can read up on this heat transfer through evaporation further here.
http://en.wikipedia.org/wiki/Latent_heat

[2003GT]

Cool. BOB

[Qyn]

Wouldn't the vapor create rust inside the engine? Please excuse my ignorance, have been watching this thread for a while and don't really understand how vapor injection is a good idea as a stand-alone mod. I can see the temp benefit, but I think that the possible problems outweight the minimal gains a slightly cooler engine provides.

[RotaMan99]

High intake velocity and rough inner walls of the manifolds cause the mist and vapor to stay off the walls.The contact time for the vapor and parts is REALLY short and the mist and vapor would be blown away by the exhausting cycle to quickly to do any damage at all. The cylinder walls always see oil when the piston moves up as well. Remember the mist is only activated above a certain PSI or RPM so while low throttle/low load or idling there is no vapor at all.

Does rust form? I don't think so but I have no on hands experience with it.

The benefit is VERY high when boosting. Some run water/methonal mix. You really only need it if you have hot intake temps caused by LOTS of boost with inadequit intercooling or if you are running on really hot days where the intake temps may not cool as much as you would like or like KewlKat said, running no intercooler at all.

For us, we could use the CRYo2 setup for a cooler denser air setup. You could make you own setup but using realy small copper tubing, bending it multiple times and inserting it into an area in the intake which has a higher airflow and running Co2 through the copper tubing. Making sure to exhaust the Co2 away from the intake.

[2003GT]

My Friend was thinking of doing something similar on his rex. He was going to hook up Nitrous to his inter cooler to help cool the air even more. BOB

[RotaMan99]

Ya there are intercooler kits you can buy. I think Co2 would work better at cooling than Nitrous but im not sure. A Bit safer probubly as well since Co2 is not flamable and Nitrous is. Combine Nitrous with the EXTREME heat from the rotarys exhaust and Turbo and you may have an issue.

[SilverElantra]

there are also methanol injection kits(i believe) for n/a and turbo applications.

[hyunelan2]

Co2 is not flamable and Nitrous is.

Incorrect.



Nitrous oxide by itself is non-flammable. However, the oxygen present in nitrous oxide causes combustion of fuel to take place more rapidly.

[2003GT]

Ya I bet Methanol would be a waste though unless you were running at a drag strip. BOB

[RotaMan99]

Incorrect.

Co2 is not flamable. I was talking about nitrous as a general term.

[hyunelan2]

Right. CO2 is not flamable. The incorrect part is where you said Nitrous was.

[SilverElantra]

But nitrous is flammable, it just takes a lot to light it.

[RotaMan99]

The incorrect part is where you said Nitrous was.

I understand..... Like I said, I was just using nitrous as a general term.

[hyunelan2]

But nitrous is flammable, it just takes a lot to light it.

No. You can spray Nitrous Oxide directly into an open flame and it will be no different than if you sprayed air from the air compressor into flame. In use, NO2 basically just allows more fuel to be burned, the NO2 itself is not really doing anything other than allowing the fuel burn in a larger quantity, and more quickly.

Read this:
Short Lesson: How Nitrous Oxide makes a car go faster. Nitrous Oxide, N20, is NOT flammable by itself. At high temperatures(in excess of 500 degrees F), it breaks down into it's two components. 2 N2O become 2 N2 and 1 O2. N2O is 38% oxygen by weight. Normal atmosphere(the stuff you're breathing *right now*, and the stuff that goes into your car engine too) is about 78% Nitrogen(N2) and about 21% Oxygen(O2). So when the Nitrous breaks down, it adds a greater concentration of oxygen than is present in normal air. Extra fuel must simultaneously be added, and the extra oxygen is used to provide the bigger bang. Same thing a turbo or supercharger does, getting more oxygen in the cylinder so you can burn more gas. Nitrous is also more dense than normal air, adding even more oxygen to the equation. In addition, when nitrous converts into a gas from a liquid when it is injected, it cools down VERY rapidly, which also lowers the air temperature in the intake by as much as 75F, increasing the air density and allowing more oxygen into the cylinder yet again, the same way an intercooler does for a turbo system.
