now that is the type of information I would expect from and evolved member.

there is a lot of good info here that is applicable and can be used in determining what cai or ai to get.

but for the 40 + replies that voice an opinion soully based on what their favorite advertisement is, and even with out installing one at all.

rhyzin, thanks for your input. did you make any other mods in the between cai/ai swaps or was the test platform the same for each? what did you do with your old intakes?

did anyone else make any swaps like this?

 

the 3kgt setup and the rmr were the same. then while i had the rmr, i got a header. the power band felt the same so i figured the header just raised the power band but didn't change it too much. then i got the aem and compared it to the rmr.

my friend won the rmr intake at a raffle at Cal Slam at the beginning of the year. since he has a 97 eclipse gsx, i swapped my 3kgt kit for his rmr since the 3kgt kit fits on the gsx and the rmr didn't. i ended up selling the rmr on evom in july cuz i got the aem for my bday. and the aem is what i'm running right now.

 

do you hae the vented hood or oem hood?

 

i started with a similar setup to rhyzin, just an adapting plate and KN filter. just like he said, it would start off with a nice pep, but would loose it all too fast. as long as you're moving, you'll still have some gains, but as soon as you stop at a light or to make a turn, all you'll have is hot air to suck in. it will BOG DOWN big time.

and living in florida, those effects were terrible.

so i saved some money, and got the aem cai from www.adventon.com the install was a bit more complicated than the sri, but once the thing was on, i loved it.

i think the reason rhyzin feels the curve is more linear is because the incoming air temperature stays more linear. with the sri, after driving for a while, the incoming air temperature is much higher in your low rpms (especially from a stand still), and cools off once you get rolling, giving you that "boost" feeling at around 3400 or so.

i'd strongly recommend the aem cai. and don't worry about any hydrolock or any of that nonsense. i've driven through 6 inches of water unexpectedly for more than 20 feet, and it didn't even hiccup.

pm me if you have any other questions. good luck bro.

 

now here is a question.........

do the vented ram air hoods (like the VIS evo viii) over come the hot air temps of the engine compartment to allow the SRI with heat shield/air box to be equivalent to having a CAI? or is the CAI still superior to that combination?

 

i think it might help, but i think cai is still going to be better. colder air is more dense, so the cai does a better job because its inlet is closer to the ground. not to mention the cost of a vented hood and sri with heatshield is MUCH more than just getting the cai.

 

does anyone have some documented figures comparing CAI's to each other. would prefer neutral test results (not some company's test) if possible?

 

dont even bother going CAI just get turbo your gonna lose the intake anyways

 

not everyone puts turbo on their car.............is that the only thing you know how to post........... i mean no matter what thread i go to "JV" tells people put turbo on it. some people have other things to do with there money than to put turbos on lancers.

is that how you got your "evolved" status. by posting "put a turbo on it ten times a day?

this thread had nothing to do with turbos, and gues what? it still doesn't it is about trying to figure out which CAI is the best, not will turbos create more HP than a CAI.......... everyone even my 7 month old daughter knows that..........

 

best would be a sri with a scoop(not a vent) or have it exposed to cold air. why? well there was this article in import tuner a while back with an intake shootout. what was important was airflow numbers as they flow tested sri and cai. the sri showed way higher flow numbers, but the warm air was causing it to put out lower hp numbers. the cai advantage was the denser air. so if you were able to flow as well as the sri with as dense air as the cai, you'd have pretty good gains.

 

i have the RMR intake but made custom intake ducts comeing from both sides of the bumper...the lower outside holes where factory fogs go in most cars.fitting the drivers was cake but i had to remove and custom make a new window cleaner tank to get the passangers to fit.did't feel much on the butt dyno at low speeds but on higher speeds and passing i can deff feel a change.
i am keeping my setup but haveing some custom 3" alum piping made for smoother flow.
all i know is the lil factory scoop doesn't do much being that when you close the hood it isn't even exposed by the air.it is at the very top mostly covered by the hood so indirect air does make it in.i know i am getting more than enough cold air from the outside to my filter...i have to clean it almost every month cause i can see the mark where the air hits it.
on another note...i am also makeing a custom scoop much like the Monster scoop that will fit behind the grill filling most the area with a big mouth to allow more air in while still being able to use with the RMR heatshield...i will post once one is done , i have just made the mold and need to wrap the fiberglass around it,just some of the perks whit working with fiberglass and resin all day

 

rhyzin, do you happen to know which issue that was or do you have a copy of the article?

 

by jan 20th. thats when i go back to skool and thats where the issue is. it'll say rsx intake shootout on front, or something to that effect.

 

cool, i would like to get that issue number so i can back order the isssue from them

thanks

 

since aem won the shootout, the article is posted on their website.

doesn't have the issue number (that i could find. guess i'll post it later on), but it does have the numbers and pics as well as the article. test car was a rsx-s. there is no graph for flow numbers. you're just gonna have to read the paragraph they wrote.

the cai's flowed at 323 cfm as opposed to 351 cfm for sri. of course since the test was on an rsx, they're not our numbers. point being is the difference in flow between intake tube lengths and diameters. and of course, the cai's won in hp only by the temp of air they were sucking in. also, testing of intakes were done in water. not on the car. this would mean that it doesn't matter if it was for an rsx or not as the efficiency of the intake is measured. not a car's ability to suck air.

i have an oem hood. nothing fancy.

no, i'm pretty sure that once you get moving you wouldn't feel a boost at 4k every time unless it was a characteristic of the intake. underhood temps are pretty high in comparison to ambient air even while the car is moving. if i was coasting at 2k in 3rd and i decide to romp on the gas, there's still that jump at 4k. torque down low is a characteristic in longer intake tubing. its in the books and is a "general" fact. (meaning there could be exceptions but is a majority of the time true)

i've seen trance's ram air setup and think they're great. once they get going, i'd think their setups would def rival cai setups. the thing about a dyno is that you can't reliably create a 80mph headwind in front of the car. sucks ***.

a combination of a vented hood and intake is something that would have to be tested. since there's a correlation between tube length, incoming air temps, and airflow, the decrease in engine bay temps would be an interesting factor. overall, i'd say it'd be close, but you can't make an engine bay the same air temp as fresh air the cai are subjected to. the higher flow numbers of a sri subjected to lower temp air is what piques my interest.
