[Mr. 5]

Yah, I'm also having a hard time believing this.
I'm just sp surprised with how many people see this and jump right on the "I'm so glad I have the BMS filter" or something like that.

this is what I get out if the results:
Something definitely happened between the runs and I really doubt that anything had to do with the AFE filter.

I am not saying that anyone sabotaged the runs. I'm just saying that something had to have happened with this dyno.

To what it's worth, I'd love to test out the AFE vs other filters vs the OEM box but I'm a little low on funds right now.
Maybe if I can get a couple people to pitch in for the dyno rental time then I'd be game.
I would assure you guys that the tests would be as accurate as can be.

I've seen that the dry versions flow is quite a bit less than the oiled version..i have the oiled version so we will see if there is a difference.. plus what was the fan situation and was the hood open or closed..alot of dynos done with the dual cones had an open hood..either way don't see how this setup could perform worse than a dual cone setup or the stock

[muvaside]

What I'm thinking of doing , just to clear things out. I'll go back in two weeks and dyno again , after the filter is prety adapted.

Can you tell me something real quick? What the fuck is your problem with Terry? He’s latest dyno on Code3 IC being not his product shows otherwise!

"Seen" like you watched 'em on a flow bench or dyno

or

"Seen" like you read it on the internet?

Oh my, aren't WE a bit hostile?

[cn555ic]

I think AFE over-inflated their numbers, but power drop because of the intake is definately not possible...Well have to see what others with this setup, dyno their cars at!

I have an aFe dry version with D1swoop scoops and haven't noticed ANY power/sound drop comparing to the DCI setup I had before. That all running "Stage 1" map on V3!

Maybe he doesn't like people who sell affordable proven products whose dynos are not inflated?

Oh, OK, forgot who that was at his place.

As for the quote above, I forgot to address.

I'm sure it's a combination of the higher octane and I'm guessing you allowed the car to cool down a bit before doing that run too.

But a large part of it was probably the octane.

As an example, on a STOCK 335i I dynoed on 91 Octane then poured in some 100 Octane to make a 93-94 Octane mix.
Did 3 more pulls. Each pull INCREASED in output as the STOCK car adapted to the higher octane.
After the 3rd pull with the 93-94 Octane mix in the car (with 5 minutes of cool down between runs) the STOCK car gained 4 rwhp

Now, I did this same test on my 335i sedan when I had the PROcede v1.2 in the car (the very first production version).
I did a couple runs with 91 Octane and got a best of
313 rwhp (267 rwhp was my baseline stock on 91 Octane 6AT tranny)
then dumped in 2 gallons of 100 Octane to make 93 Octane
Ran the car on the dyno rollers for a minute or so, to let adapt, then let it cool back down for 5 minutes.
Ran the dyno again, and got
325 rwhp
A 12 rwhp gain from going from 91-93ish Octane on the original PROcede v1.2 when peak boost was only like 13 psi.

So as for your 16 rwhp gain with 94 Octane.
I would say 12 or so of them was from the Octane boost, the other 4 was probably from a bit of cool down (and possibly a bit from the intake).


As I've said, 93 Octane is good for 8-10 rwhp over 91 Octane.

[Sneeze]

People bought AFE for looks soo don't complain on performance.
I want to see a comparo on two diff. intake.

[possible335i2008]

no I have not actually seen this on a flow bench..even if I did I wouldn't know what I was looking at...just from reading in the forums and afe literature...either way dyno comming very soon and we will see from there...i have had mine on for about 2 weeks now so it should be adapted...plus my first couple of days the car really needed to adapt..it is very smooth now..sorry if this is chopped up typing this on my phone

[Flat Out 32]

Don't get me wrong, not here to bash anyone but I'm happy with my aFe and there is definitely a power gain which for the price makes it good. In 300+ hp a gain of 5 is barely noticeable in the street so this intake gave me more and I'm liking it a lot! (not the looks, I cannot see it from the cabin )

[JB335]

I've had the JB3 installed on my car for a few days now. At first the power was awesome and my car felt amazing.

Next I filled up with some 100 octane. There is a 100 oct gas station right down the street I had 1/4 tank of 91 oct and 3/4 of 100 oct.

The first day with race gas it felt much smoother. Much more aggressive.

The second day with 100 octane the car became a beast. The car was adapting with the JB3 and the 100 octane. Both began to sync at once.

Today i installed the AFE intake and my car is an absolute monster. D feels like DS and DS feels like the car wants to rip out from under me.

Whether the intake increases power or not it is much more smoother. It requires MUCH less throttle to "go."

Today was the first time I was a little scared flooring it. This is how the car should have driven from the factory.

[hotrod182]

Terry already stated that the intakes are good at least for their sound quality (subjective). He said any benefit is probably at the higher rpm range (5000+). He want on to say he wasn't claiming his intake filters were any better in performance, but at least they are very affordable. For what its worth, I ran about 16 runs switching back and forth between the K&N and stock filter. Finally I removed the filter after determining there was no measurable increase in performance. My car has run fine, with an absolutely stock airbox and filter set up. Also, about accleration feel, and the sounds that your engine makes. It is very deceptive. I have had times when I swore my engine was running great with savage acceleration, only to be disappointed when I found it performed no better, or was even worse than previous tests.

yeah... but if they do, then they would come out with hefty price tag...

heh, this is true.

Plus, semi-sleeper FTW

[Tarthuss]

Not to be the bad guy here but what do you expect from a company who claims 25 horsepower from an intake?

They even have one they claim puts 50hp!

Sounds VERY FAMILIAR!! AFE direct competition

What does turbonator has to do with AFE intake? everyone knows turbonator is a scam and im sure AFE is not. it may be more expensive but dont mean it's piece of junk like a turbonator.

now, i know an intake doesnt do much on a NA engine car but in a turboed car, it gives much higher gain. whether it's 20+hp or not, im not sure until i've done my own dyno, but it def. adds alot more power to a turbo car than NA.

i'm not sure why alot of people are so skeptical about AFE yet believe BMS dual to put out the power that they claim? AFE is only been out for a month, give it a little more time and we'll all know whether it's worth it and whether it's putting down the type of power they claim.

I agree. Butt dyno's are very deceptive. Comparisons can be also. My trap speed went up by 1-2 mph when I added a K&N drop in filter.

I went to the track on a Wed night without it, then returned on Thurs with the K&N in place. I killed it out there with the K&N on Thurs. Everyone kept asking me what I did to my car. I said "nothing, Just a K&N drop in filter"

The replies I got were like "wow, that K&N kicks ass"

This was same track, almost same ambient temps, only 1 night difference, same octane.

I really do not think the K&N filter had anything to do with it. Different conditions, albeit slight, I believe can affect this car dramatically. One has to be very careful in evaluating the affect of performace products on this car....

It is very hard to compare changes to your car with varying conditions. Especially on different days, etc. Unless you make dozens and dozens of runs, and even then its hard to say what is happening at times . I am going to go out and do some more testing this morning before I draw any conclusions. As far as my K&N testing, I thought at first, "wow, this thing makes power", but then after 15 consecutive runs, I realized it probably made no difference whatsoever.

Here are my K&N test results:

Well wednesday is the day, will be heading to alamo motorsports which has a dyno jet dyno, (i think that is right) they are very popular with the corvette and supra crowd here in the dfw area, they have done tons of dyno's and they have a very good reputation out here, if anyone in the dfw area wants to check it out pm me, this will be a completely independent test, as no sponsors nor anyone else will be paying for the dyno (comming straight from the piggy bank) so hopefully this will be a good indicator of the strength of the afe intake with a jb3 on 93 octane, will not be using higher grade octane, and will do 3 runs all with the hood closed...if anyone has anymore suggestions let me know
