Is there any big difference between the older aem cai and de Aem v2?
Does it compensate the huge difference in $?

Thanks for replys, sorry for all the questions i starting to build the car and i´m trying to make the less mistakes as possible

 

i have the v2 and i cant complain at all

me 2. it gets

 

I have a regular Aem cai, it gets it done. If I had more money I would have went with the v2

 

It's up to you.... I don't have either. Everyone has their own opinions about it.

Don't believe the dyno charts they show you though. Those results come from extremely built engines. They will dyno this built engine with the stock intake on, then dyno it again with their intake and claim you can get that much out of the intake.

For a stock engine, I would expect no more than 5hp out of an intake. That is unless you buy some $800-$1000 intake, like the ARC intake.

I hope this helps.

 

how much would an ARC give you?

 

the arc intake makes more power only because its not a cold air intake, the longer the intake tube the harder it is for the engine to pull air through it, just think about drinking a drink through a five foot straw or a ten inch straw which is easier. short ram almost always makes more power than cold air. almost

That is not entirely true. The ARC intake has a special filter that allows more air flow or something. I can't remember what it is but I read it is because of the fitler elementS.

As for the difference in power between CAI and SR. Short ram intakes make more low end power, while CAIs make more power up top.

well you gotta think about the diameter of the piping (or straw in this case). the bigger it is, the easier. but then you want to think about air velocity also. the more velocity, the cooler and more dense the air is.

theres a fine line in there.

i'd really like to see a REAL review of these intakes though.

 

so you are basically contradicting yourself, you said the bigger is better than you said the smaller is better. arc uses an air box between the throttle body and air filter, this allows that bigger piping you were talking about, this box also allows for standing air which can be used by the engine under quick air exceleration and also as a place for the moving air to go when you close the throttle. under steady flow,open throttle, the air passes through the chamber without disturbance. this is one unique feature of the arc intake. youre right when you said air has velocity, it also has mass, this is why a long pipe hurts performance, even though you make the straw bigger you still have to pull this mass from a further distance which is harder for the motor.

I have the regular aem cai and a aem v2 cai, for me the v2 feel more stronger in the high end but lacks in the low end a bit comparing to the regular one, but the regular one has more torque in the lower end but the high end is not as good as the v2, comparing them both. I ran them both on my bone stock b20 a while back. Just my $.02.

 

Probably not worth the extra money for a couple of horsepower. I'd recommend improving your car's braking characteristics.

 

that´s a good recommendation the car does not brake very well i notice that!!

Intakes aren't designed for flow.

If it was based on distance and ability to flow to make the most power, then having a 5 in diameter, 6 inch long tube would make more power.

But it doesn't

WHY?

Cause a intake is also a tuning device, in which you are tuning the sonic waves inside the engine rather than just focusing on flow. The diameters and tube lengths determine where your torque peaks will be in the rpm range. The V2 intake was designed to give a midrange torque peak for good street driveability and good top end power for all out driving.

the bigger, it is easier. just think about it. but then there is a point where you lose air velocity. thats what im sayin. its just like if you took a big jack n the box straw and a coffee straw and you tried to suck in air through them. the jack in the box straw is easier and its longer than the coffee straw.

its like a balancing beam act when youre trying to get both sides of performance in there.

just get individual throttle bodies

Yea, with the headlight removed...

psshh... engines dont like hot air, and an enclosed bay with an engine isnt hot at all ... i swear

 

now theres an idea!

Usually the cold air intake has a nice midrange increase, but the short ram makes more peak power up top.

You don't use full throttle at a stop light, I swear.
Once you're moving, air pushes through the bay, it's not as hot as you might think.

 

Cold Air= More top end power
Short Ram=more torque

Thats what i have found

other than that its all machine work and AEM has a smooth welds and cutts but could use a little polish on the inside..sometimes they're ruff LOL

 

ok, really simple.

i red in 2 mags.
stock civic ex. did a dyno shootout on intakes.
the AEM CAI put out like 4.somethng whp, and they then AEM V2 put down like 1 hp less. ON BOTH MAGS!!!

I WAS LIKE WTF&gt;
think about it though, sure you have bigger tubing, but look at the connection to the T/B. it goes back to the stock CAI size, so wtf. its craming all that air into the stock sized piping that fits to the stock size t/b for that matter, so basically i see it as completely pointless.
it just has that big piping cool look factor to that.

hell i think the AEM cai is a waste of money,
i could buy a nitrous kit for that much

for the time that i was N/A with nitrous, a regular short ram ebay intake did me fine. 20 bucks

 

Here's a graph I just made up from a test I was involved with. We had a 98 Honda Civic EX with a header, cat-back, and all three AEM intakes. The graph explains it all. Tests were done back-to-back and an average of three runs.

Green = AEM V2
Blue = AEM Short Ram
Red = AEM CAI



You can see how the V2 intake has a mid range torque peak and is also tuned to give top end power like a short ram. The standard CAI gives a later torque peak but looses too much right after it.

It's actually the other way around.

 

im old school...stickin with the good ole AEM CAI
