K&N 77 vs. AEM Brute Force

blachow · 03-10-2005, 07:41 PM

I see there's a big push now towards the AEM brute force b/c of the dyno numbers. I have a question:

Why not the K&N which is claiming the same numbers, but actually @ a lower RPM.

Here's the AEM Dyno:

http://trucks.aempower.com/pdf/dyno/...itan%20BFS.pdf

It gets 17.9 extra horses @ 5150 rpms

The K&N gets 17 extra horses @ 4865 rpms

http://www.knfilterchargers.com/sear...Prod=77-6012KG

The K&N isn't CARB legal, but the AEM hasn't been approved either.

I'd like to hear the input. I'm not sure which one I would get since I'm not a big fan of any metal intakes. I live in FL and you can't get cold air through a metal tube that 120 degrees.

I'd be interested in the groups opinion though.

Thanks,

i have the k&n 77 intake and it is street legal tere are 2 different kinds one for one road and one for off road(which isnt street legal). im happy with the performance i get from it and also the sound when accelerating

Volant owns all!

*True Story*

Actually, I would hold out for members to dyno with the AEM. I would never put too much credibility in the manufactures dyno numbers (they all seem very optomistic).

I would think all the CAI systems would dyno near the same, there is only so much you can gain from a simple mod.

I was told that everything the AEM sells is street legal, at least for CA. It has a C.A.R.B. number to it.
I think your going to get the same out of all of them. However, the Volant is a true "Cold Air Induction" because of the incloser and where it pulls the air in from. The AEM and K&N are prone to heat soak. A buddy of mine had a AEM on his SRT-4 and ended up yanking it out.
He said that on hot days or long runs with it, the performance gains subsided.
He has always told me that stock intakes are so much better now on todays cars and trucks that any after market intake for the most part is not worth the money for what little you get. He did say you will get more out a drop-in filter than anything else. JMO

Yeah,

I agree with the Volant - that's what I'm leaning towards.

It just bugs me b/c they don't have a way for me to have the "ram-air" tube installed b/c I have the Off-Road Package. I'm told the skid-plates and the tow hook are screwing me up.

I would drive around with only one tow hook, but if the skid plate is going to screw it up, well, I'm not taking that off !!

Any suggestions?

IHeres an article on intakes. No aem comparison though.

Remember that test is done on a Ford so those results dont really apply directly to the Titan.

dragonhead08 · 03-11-2005, 11:03 AM

right, but you can see what variables affect what. And even with a sealed box and plastic tubing the volant produced the least amount of gains. Though it was the most consistent prbabably due to its plastic and sealed box. So until someone does a straight back to back dyno comparison this is as good as it gets to make a choice. Plus even with a dyno you have to keep on mind that were talking about stagnant air. Also if you live in Arizona or Texas the volant may look the best choice, but if I live in Daily City I'm not too concerned with the heat. I'm no volant basher, hell my last truck had one and I loved it.

Again, on a FORD! The review also said they have seen 10-12 hp gains from these systems on other vehicles. Why would we need to see a test on a Ford to compare when we drive Titans? Apples to oranges to me. We already have dynos of folks with these on Titans, that have gained much more than the 4hp gain on the Ford (~15 hp).

Good article...wrong truck.

It was done on a ford, but the Volant still showed the least gains. So you should revise it to "Volant owns the least power"

Just a friendly joke! I own a AEM intake so I thought I would poke a little fun at you.

ok I think you're missing my point. I'm not so much trying to make an hp prediction on the Titan but more about how the intakes perform against each other based on their design. Such as metal vs. plastic tube, sealed or non sealed airbox. So yes, I agree you cant take too much from this article but you get a good idea of how a volant compares to a K&N.

m95roadster · 03-11-2005, 03:27 PM

There are variables involved that people are not aware of that will affect hp/torque. i.e. the length of the tube and/or diameter. Miata club members (I also own a miata) have found that removing the resonator on the intake tube resulted in a torque loss of 4 ft. lbs.. That's alot on a 100 rwhp vehicle.

Timba24 · 03-11-2005, 03:57 PM

you also have to consider the frequency of which the pipe creates within the intake I know it sounds weird but it makes a difference. Also yes its a ford different engine take to different mods and the volant may be the worst on the ford but it could turn out to be the best on the titan. Anyways I have always ran a metal intake pipe it to me it didt seem to make a huge deal unless it was a short ram intake but even then a plastic one will get heat soaked.

Yes, that's why there are resonators on factory intakes to "tune" the pipe. Frequencies have different wavelengths so length and diameter will play a part here.
