Anyone with a CAI, no matter if its Injen or Custom. Has anyone found another place to route the piping and filter so it won't get wet? Or has anyone custom made a guard for the filter so it won't get wet. I ask this cause I forsee it getting wet when you wash your car or it rains, from either the holes in the grill down by the fog light or water coming in from between the headlight/bumper. I'm not worried about water from underneath the car or the air dam in front of the tire. Just from the headlight area and from the grill around the fog light. I've seen the pics of the injen CAI design and was thinking maybe having the pipe a little longer so the filter is up higher or having some kind of shield around it in the front so water would hit the shield. I'm just waiting for the SRI kit that I got from evosoul so i can use the pipe that houses the MAF sensor and custom make a CAI out of it.

 

I bought the injen hydro filter and no problems so far. I have also hit a pretty huge puddle in a rain storm one day.

 

i was kinda not wanting to do the hydro filter route but if it really does keep water out like it says then i might just do that. I'll post pics of it and its design once i get that part from evosoul, (canada isn't really good at shipping stuff fast, then again neither is the US so, ). I should get it end of this week or beginning of next week and i'll get with my buddy thats gonna be making the piping for me and get it done. I'm just afraid that water will get in from where the headlight is and get the filter wet. Also what filter is better for overall performance. LOL

 

Sorry for the slow shipping. but it will get there one day lol, your children may be thru school and married but, by george, the mail must get thru!!!

as for the CAI, I really have to put this myth to bed. Heavy down pour or not. I can take a hose and spray my filter all I want with it, nothing is going to happen. Even at wide open throttle, any water that does make it to the engine will evaporate. A hydro lock death blow has to be alot of water getting in there.

All the cases I have seen of hydro lock are when a guy droves his car throw high water conditions / flood. Its grusome but if you ask them, most of them would say, I didnt think it would happen, the puddle looked so shallow lol

 

are there no short rams for lancers yet?
i was looking for them, but couldn't find any.
i guess that would be one way to avoid it since the rams are above the engine (in most cases if not all)

 

^^ i did a test on IAT temps (with the Injen CAI, RRM SRI, and the stock one)

I would rather go back to stock then put an SRI (at least the RRM one) on my car. +17 deg C ambient temp increase (that is 62.6 for you Yanks) OVER AMBIENT. So the example being that if it was 60 deg outside your intake air temp would be 122.6 degrees.

So much for ANY power increase you would see.


the CAI was +2/4 and the stock was between +6 and +12 C

 

ooo. so SRIs are out of hte question then.

 

^^ for me, you can do what you want.

The problem with the lancer SRI (any company unless they have mitigated this) is that the filter is EXTREMELY close to the headers.

 

LMAO its not you EVO its the POST OFFICES in canada and the US that SUCK. I looked today and the damn thing is still sitting in MISSISSAUGA, ON where it was processed at the postal facility on the 15th, the same day you sent it out. Thats just retarded to me, but for all i know its going through the customs check and will only take like a day or 2 to actually get to my postal facility and delivered the day after that.

 

With an SRI you might not gain more power, however since air would be getting into the engine sooner (since the piping is smaller), you'd get better throttle response (am i right on this all you other more educated people out there? )

In addition to this, since the air going into the engine is warmer, the fuel is warmed slightly more, thus expanded it, giving the molecules more surface area. With more surface area exposed, the fuel can burn more completely, thus giving you better gas mileage.

Lastly, off the top of my head, with the SRI you get an increase in low end torque. I don't know the physics and such behind that one.. but I've read in many places that is the case.

I'm bringing up these points because to some, including myself, I don't see much power coming from these NA mods, so the SRI is a likely choice for me given that it improves the things i stated above. This in no way bashes a CAI. They are great as well cos should be able to tell you all about that since he has one lol.

One last thing to mention... RRM has come out with a V2 SRI. It has a heat shield... I'm curious as to how that intake will handle the heat... the temperatures cos gave are quite distinct. If the SRI V2 can get the air down to par with stock intake temps (or better), it would be a definate go for alot more people, including myself.

 

if you plan only light mods then SRI should be fine. better throttle response is always good. just don't expect a lot of gains.

if you plan to do a NA build up with cams, etc. when available, then hold off. once the head is up to snuff, the SRI will just be sucking in hot air. once you get the head and the rest of the engine (crappy plastic IM) to flow better, it will make better use of the cold air.

CAI's don't flow as well as SRI, but there comes a point where the better flow of the SRI is negated by the hot air, and vice versa, the poor flow of the CAI will eventually be outweighed by the colder air. this is all dependent on how well the engine/head flows of course. you may need some big cams and headwork to see the advantages of the CAI. that's why 90% of people buy the SRI and are happy with it.

also heat shields are only effective if they partition the air that is sucked in and the underhood hot air. a "heat shield" like on the V2 RRM SRI looks to be merely cosmetic imo. i'd love to see some IAT proof that this "heat shield" actually works. the only thing that it looks to be doing is to prevent the filter from getting hot, but what about the air going through the filter? nothing to stop it from going around the "heat shield" right?

 

to me i think the best intake for this car would be a CAI, but id want to take the stock air filter out, move the battery over to where the filter as, and throw a CAI pipe str8 across and down. that would be perfect.

 

I don't think many will be going with an NA build so an SRI should be fine for most. But I definately agree with your claims on a CAI being better for a more advanced NA build.

The heat shield comments... again i definately agree. Just saying it'd be nice if it did make the SRI take in cooler air Let's hope whoever gets it is able to get us some IAT numbers and such

I think everyone who has looked into the CAI would like that lol

 

On this, you are right.

On this you are wrong. if warmer air would be better for performance and gas millage, that would defeat the theory of the maker of the lancer that made a duct to the front of the car, ot better yet, the theory of the N2O system, right? Do a bit off research on how much better it cold air than hot air to the intake


True.. I really want to see results on this. BUT.... although it has a METAL heat shield ( metal transports heat faster) the filter is not isolated from the heat coming off the engine. it is still sucking hot air from that general area... this is an isolated filter to me:



Here when the hood closes, it isolates the intake completely, and sucks air from where the stock filter box would have been. (ALL the cars are made by default with an intake that sucks cold air from the outside of the engine bay)

Another story to prove this... like 3 weeks ago, i was running with a friend of mine from another forums.. we were running in a track btw ..... he has a GTS and i have a DE, we are BOTH cvt.. we ran 5 times a 1/4 mile.... he has the rrm sri v1, the rrm pully, works exhaust and lighter rims... my car is bone stock.
the 1st run he had me by a good 1.5 links, the second pull he had me by half a link... the 3 pull i had him by a fender, the 4th and 5th pull i had him by almost a whole link.
what does that tell you? one thing: heatsoak. as the car got hotter and hotter, the performance kept on going down.... so imagine you in a good 30min+ trip... at first its gonna be awesome but as your engine bay keeps getting hotter and hotter, there goes your performance and gas millage.... and this is not bashing RRMs SRI... when i was in the DSM world i would bash all the SRIs in general... it just doesnt make sense to expect HP gains sucking really hot air from the engine bay IMO..

someone correct me if Im wrong please

 

Comments on performance i agree. It's not going to gain better power because the air is warmer so there is less air in the cylinder therefore the combustion doesn't have as much energy. However, where you said i was wrong, I said nothing about power gains. I stated fuel mileage gains. I did research and that is how I found out the SRI gives better fuel mileage. This is stated on wikipedia as well as another site (an automobile oriented site that teaches about engines etc). The means of obtaining that better mileage may be wrong (I used logical reasoning and my knowledge in physics (I'm a university student majoring in science) to come up with a likely reason for the more complete burning of fuel which leads to better mileage.

Again, the gradual heating of the engine bay resulting in warmer air intot he engine is shown in this loss in power (under the assumption that both drivers remained at the same level of skill during these runs). However, this shows absolutely no evidence that the SRI does NOT result in better fuel mileage. You can't tell mileage from 1/4 mile runs...

The increase in HP from an SRI is from the increase in air getting into the engine. However, as seen in your runs, this increase in air flow is eventually negated by the air getting warmer. Also, the increase in airflow giving power gains compared to stock is highly dependent on the stock configuration. The noticeable increase in airflow will only be present given that the stock intake is restrictive.
