Re: AEM - Nismo Intake

This is still early development but you can bet it will perform just as well, maybe even better than the AEM.
As for that mechanic that believes oil-gauze filters are the second coming of evil....he needs to crawl back into his over-priced snap-on toolbox. This problem popped up a long time ago at ford and it was due to grossly over-oiled air filters. Today, the amount of oil going into the filter is precisely controlled. Also, MAF sensors are not open wire systems like the old fords, but know they use a bypass chamber in the sensor itself to help rpevent contaminating the wire. Basically you have nothing to worry about unless your filter is drenched and dripping with oil.
I have only run oil-gauze filters on all my cars and have had no problems at all, ever, period!

Less Horsepower?
To my dismay, I was just told the Nismo CAI doesn't actually cool the air into the intake. Due to the placement of the filter, it creates a suction, which in turn heats the air, which in turn creates less horsepower. I may not have all the facts straight, but a little birdie told me technosquare's R&D have talked with Nismo and recommend just putting a drop in filter with the original intake. Can this be true? I already have the Nismo installed. What should I do?

Tell me who at nismo they talked to, I know a lot of people there.
What you should do is not post dumb crap on forums. Also you should wait to see what they come out with next. Or hey, maybe try dynoing your car!

All I was really doing was trying to help. Colin at Bulletproof Automotive gave me this information. Take it up with him. Are you angry cuz you have one installed or is it time for the daily pill?

somehow i doubt that the cai makes you lose hp, but from what ive read, the stock intake is amazing on the Z, so just putting in a drop in filter like a K&N isnt a bad idea

Thanks Chebosto! Is this a better solution than just putting back on the old air intake with an S-Tune Filter? (Thats what I had on before) Is it actually loosing horsepower or just not gaining that much? Thanks for the advice!
#49
imho.. stock air box with a higher-flow rate filter (ala K&N) and you cut a hole in the front bumper exact location of the stock air box hole would yeild you better results when driving than most aftermarket intake systems....
but if you already bought the AEM, either remove that piece, or punch a hole directly underneath the filter in the underskirt and get a funnel ...

Obviously you guys dont do any testing. The claims you make are based on your judgment, which is usually falwed. I am a mechanical engineer, active member of SAE, former team leader of my schools Formula SAE race program, and I am currently employed in the automotive industry and spend my days at work disecting cars and parts.
I dont have an AEM intake, I dont even own a Z, so I am not trying to make myself feel better. But I have spent a rediculous amont of time behind the wheel of a Z and used all the major intakes.
Have you ever tested where the air to the filter is coming from? Do you know exactly what is going on in the filter area when the car is cruising at speed? maybe using thermisters and a data logger? or maybe you re-created the whole scenario on your computer and used advanced FEA flow software to simulate what is going on? Have you done any dyno testing? Do you have any dyno data to back up your claims? Do you know how difficult it is to dyno the Z due to its highly evolved engine management system and super-active knock sensor? Do you know that Dyno results can be manipulated through various ways to make any part look good?
How about this..If you say the air is heated up by the tube then imagine a perfect engine with no pumping losses, say a 3.5L running at 3000 RPM with a 3" intake pipe. THeoretically it would be sucking in 185 CFM. For a 30" intake system, the air would be in the pipe for only .036 seconds. Enough time to heat it significantly? Nope. Not even with a high convection coefficient (h).
The problem with forums like this is that it is just a place for bull-sh*t to circulate. Pure and simple bull-sh*t.
Dont write back unless you have solid proof and facts. NOT speculations.
thanks

Heres some facts:
http://www.courtesyparts.com R-tune Intake $324.92
http://www.aempower.com AEM Intake + Bypass $357.13

Geez, compression, why are you so angry? This kind of fourm, people can post whatever opinion they have and we are not so stupid as to believe everything that's posted, including dyno results. Are you here to boast? Or can you offer us facts. Like, you said you've used all the major intakes out there. Then, pls
tell us which intake to buy per your test results. That would help us a lot.

compression,
Get the H3LL off the board if its just full of bull sh*t. I wouldn't want any of our sTupIedness to rub off on someone as brilliant as you. These companies know that some people who buy their products are going to have their cars dyno-ed. So why would then lie about there gains? If I wasn't so damn stupid and full of bull **** maybe I could answer that question?

There's a lot that goes into the design of an OEM intake. By not having the proper design, they can actually make the car run like crap. Until I start running big HP numbers, I'm going to trust the Nissan engineers (well, with the help of a K&N filter).
BTW: there's nothing wrong with these forums, as long as someone calls out the BS...Everyone is entitled to their opinion; just don't think that it's fact until you check it out...

i think he's saying that the air being sucked up by the engine cannot phyiscally heat up the pipe due to the fact its only in the pipe for less than a second.
but its not the fact that its the air heating up the tube (from air friction) is the fact that the engine bay is heating up the tube from the engine's own heat... but thats not gonna help much if the filter isnt sucking in cooler air than it could get if the air was taken from more of a direct source of fresh air such as from the front of the car while driving....

ok smarta**, you are a mechanical engineer. you tell us "obviously you guys dont do any testing". no shi*! yeah, im sorry to say i dont have any thermisters, or FEA software installed on my desktop. am i supposed to? for the average person on this forum, they get thier info any way they can, and its not always 100 percent accurate. this is because we dont have the proper test equipment to verify our facts. but, we share what we know to help others out. you dont even own a Z? then why are you on this forum? so if we are wrong then give us some helpful advice instead of coming on here saying how F'd up we are. no one cares what job you have or how smart you are. either say something constructive pertaining to the topic at hand or log the f**k off. feel me?
