Intake opinion

[crypticfury85]

Hey guys,

I'm looking for an intake, which do you guys prefer more? Injen or AEM, and how much would you pay for it or did pay for it. If there is another brand that is good, let me know. thanks!

[Eternal_240Sx]

well.. i have aem and it gave me more mid range power but not very noticable power.

i paid 125 new for mine.

[syco3d]

I got an AEM for $125 as well. Looks great, sounds great, and definitly noticed an improvment. Cars I barely lost to b4, I'm now beating. I just wish I had 1/4 times and/or dyno facts to see just how I did gained. Don't expect a drastic improvment from any Intake- but it's most definitly a worthwhile bolt-on.

[pinoydrifter]

AEM- souds good, looks good, and is good quality!

injen- cheap

...... go with the aem! I did.:D

[Kreator]

Summitracing battery relocation: $50
90deg 2.5" mandrel bend from JCW: $10
K&N filter: $30 (summit)
Adapter: $8 (ebay)
Rad hose: $8 (peterbuilt)
sensor bungs: ~$15 from yer local muffler shop

Total: ~$121 which is less $125 AEM intake and comes w/ quicker throttle response and better weight distribution :D

LOL, first time i hear that

[s13fastback]

aem ... cheaper price and i think a little better results ....

[crypticfury85]

Hey I have a 98 240sx where did you guys buy it at for so cheap?

[syco3d]

EBAY!

[twitchy]

Heres what to do:

Take off the stock baffle. The sound will be the same or better as the kit your about to spend money on. This constitutes the horsepower gain (what 15 horsepower?*)

The horsepower gain? Well to get the same effect, take out your spare tire and thats how much faster youll go.

(*mental horsepower since all is does is SOUND more powerflu)

Flame away if you like.

FRIKKIN' AWESOME!!! Why spend one fifty on an intake when you can just take out the donut! :)

[twitchy]

take a stopwatch

take your stock system and time yourself accelerating or between 2 objects or whatever

then make your system less restrictive IE take the filter (cant get much less restrictive than that) out for a run or 2

and time again

do it 100 times if you like


Youll notice very very little if any increase in acceleration (power)

That's true, I noticed somewhere they showed that intakes only have like 2 to 5hp gain (if even that). And that a setup like intake/ehaust would only give you an extra 20hp maybe

only 20 hp! from I/E:rolleyes:

that is pretty good if it were true, more like 6-12 whp from I/E combined.

[SilviaNinja240]

well, whatever around there. Not too much hp gained was my point:rolleyes:

[s13rookie]

yeah, take out your donut, that is cool, UNTIL you get a flat

[twitchy]

or whatever

what do they say, one horsepower is like 20 pounds or something??

I dont remember exactly but its something like that

[Kreator]

No, fool

they say 100lbs is about .1s in the 1/4 mile

Horsepower is the same no matter whether your car weighs 5000lbs or 3000lbs

Who says that? Are you just talking about 240s? Cuz 100lbs off a 4000 lb car is alot less than 100 lbs off a 2000 lb car.

[twitchy]

EQUIVALENT horsepower

if you know how horsepower is calculated one of the ways is a function of acceleration and weight

so less weight is more acceleration and when you recalculate its more power

edit- "dork face" is inappropriate. DO NOT CALL NAMES..

[sykikchimp]

an Injen CAI will produce more power than an AEM SRI. period. The injen is NOT crap. It's is very nice quality.

Ok sorry, shoulda thought of that. That's what domestic boys say, so prolly off of a ~3500lb car..... so refrazing, 3% weight save is about .1s in the 1/4 mile. but then even this is a little inaccurate :-/ (as in it will prolly take more weight to get an 8.1sec car down to 8.0 then a 17.6 to 17.5)

twitchy:

WTF do you mean by equivalent hp?

Bah. Dude, the negative change in weight and positive change in acc will come out to the SAME EXACT NUMBER when multiplied!! gues why? CUZ THE HORSEPOWER OF THE ENGINE DOESN'T GET AFFECTED BY THE WEIGHT OF THE CAR IT'S PUT IN!!!! go study some physics before arguing your bs.

When they tell you the numbers the engine in your car produces, they get them (in most cases) w/o even putting it in the car.

[twitchy]

You can calculate a cars horsepower given its quarter mile time and its weight.

There is a constant in that formula and im trying to locate the formula to show you.

Horsepower as I am mentioning is not the traditional way of calculating it. I know they measure it on engines without them being in the car.

NOW using our formula

lets say that for the sake of being easy if your car accelerates at x rate and weighs...5000 pounds

then you change that 5000 to 3000 and the acceleration is faster

so there is more "horsepower" although the engine is not changed, the car is faster.

AT THE SAME TIME that same amount of horsepower gain could be added to the engine to geneate the faster acceleration with the heavier weight

maybe with the aem sri, but believe me the difference from stock to an injen cai is alot more then the pathetic crap youre talking about

(coughs)bullsh*t(coughs)
you could get a vague idea of a cars horsepower by doing that. quartermile time doesnt just have to do with a cars weight and horsepower, theres also suspension drivetrain unsprung weight tire and wheel size DRIVER

LOL dude.... you non-traditional way of calculating it ends you up with your lets call it "imaginary" horsepower, as it is not horsepower at all. I'm seeing what you are trying to say, but it's completely wrong... well not wrong, but it has nothing to do with horsepower. So don't name it that way.

As for the formula your trying to find:
hp = speed * acc * weight is the one listed at G-Tech website.
Now, d=1/2at^2, so a=2d/t^2 so now the resulting formula is:
hp = 2 * speed * d * weight / t^2
if you want to argue again, d stays the same (as is the speed as it's just to map the values) we get a change in weight and 1/4 mile time. And again, reducing weight proportionally reduces 1/4 time so what you get is still a constant value.

and the car being faster has nothing to do with the power the engine makes. The trucks make about 500hp, yet i'm pretty sure my 80hp escort will easily beat it in a 1/4 mile. So don't associate car being faster directly with the engines horsepower.

can anyone give me the stats of injen and aem, such as the outpurt of each intake.. thanks

[Kreator]

Ok, sorry we hijacked your thread, so to redeem myself:

Both injen and aem will mostly likely give 3-4rwhp and maybe 5-6ft-lbs of torque. That's on a stock car with engine in perfect condition. with exhaust, headers or what not, it might be a little bigger. The injen however has a CAE which will give another 2-3rwhp... dunnow if u can fit it to aem

but hohestly, read my first reply. it's not plugnplay, and requires some work, but you will be more satisfied in the end with the results. Plus nothing brings more joy then seeing something you made yourself actually work.

[Bliss]

whats a CAE? Cold air extension?

[s13rookie]

exactly, but with a few intakes, putting your intake in the way of colder air, you mat risk injesting air, get an intake bypass valve
like 50 bucks

injesting water?

[Black 97SE]

The Aem and Injen short rams are very similar.
The Aem is what a 2.5inches in diameter where as the Injen is a 2.75inches in diameter.
The injen comes with the cold air extension where as the AEM doesn't. From what I know, I don't think you can connect the injen CAE to the AEM SRI. But, you can put on the bypass valve from AEM on the injen intake with the CAE if you're afraid of getting hydro locked.
The chances of getting hydro locked are so slim. You have to be pretty much an idiot to get hydro-locked, and when that happens, sucks for your engine. To get hydro locked, your filter has to basically be completely submerged in water. In other words you'd have to drive through so huge puddle that completely covers up your filter, or drive through some river where the water is up to the middle of your rim. If you're not driving through some pond or stream, then you shouldn't have to worry so much about hydro locking. There are plenty of people I know who drive with their CAI through heavy rain without any problems at all.

[Black 97SE]

Oh, yeah, woops back to the question of this post. I think if you're so positive that you won't get a CAI, then go with whichever intake you think looks better or whichever one you can afford. But, if you have a feeling that you want more power and will get the CAE in the future, then go with the Injen.

Aem = short ram only (2.5inch diameter)
Injen = possible CAI (2.75inch diameter)

[Kreator]

just to clarify - the diameter of piping will most likely make no difference as the diameter of yer throttle body is still only 2.5".

[nismo_sr_20]

with the cold air extension. the filter is very close to the ground compared to normal filters. so if you go through a deep puddle or somehow manage to get it wet. your car wont run as good. with the air bypass valve whenever your intake does get wet theres a drop in pressure in the piping which will open the air bypass valve and your intake will start taking air in through it.

[driftmaster0717]

i have an aem in mine. It looks good, sounds good ,it is great quality and it made a noticable improvement. It cost about $189, but it was worth it.

[Black 97SE]

wow, you paid a lot for your AEM. $189? Whoa. hehe. The chances of you getting hydrolocked are so slim. You pretty much have to be a complete moron to have that happen to you. So yeah. The intake has to be completely covered with water ALL AROUND to create a vacuum to suck the water up to your engine. It won't get sucked up unless there's a vacuum.

[ridebmx]

alittle OT, but i just drove through a pond that was all the way up my hood, and met the windsheild on my nissian pickup truck(only way to get out to a awesome camping spot) and i had no problems, i seriously wouldnt worry about hydro locking, i shouldve taken pics, but it was just me and my g/f, and it isnt like i can just hop outta the truck in the middle, haha

[muskrat]

I don't put air intake kits on cars for more horsepower, I put them on for better throttle response. Take that however you want it.

[nismo_sr_20]

the abv isnt just for hydro lock.

From personal experience and physics, putting a wider intake in place of the stock one will reduce throttle response :o and thats not including the CAE (which will make it even worse)

[s14vaxlr8]

ive got a full injen cai for $180 if ne body wants it

[Black 97SE]

I'd order the intake from you, but I don't think my dad would like that haha. Oh well, tomorrow I'm going home and ordering 1) HS headers 2) Injen CAI 3) Blitz Nur Spec R. Yay for me

[crypticfury85]

Hey Im interested in the cold air intake. Email me if you still have it. [email protected]

thanks
