Hey Back2ford: That certainly makes me anything but mad. I seriously considered taking part in the group buy of the filter. I am always searching for anything that enhances performance. I hung $13,000 worth of add-ons to my last Harley, and put every performance tweak that I could find in the beast. It sounds like it is working good for you, and I may have to consider it myself. I don't take this too seriously, I am here because I am in love with my ride, and I follow these threads religously, always hoping to glean something useful. I do wish the difference (if any) between using a K&N in an airaid, and the other filter could in fact be measured. Unfortunately, I am an engineer by schooling, and I like measureable data.

Sal gave us the data a long time ago, as to why he used the powerstack type filters over a K&N type. to give you an idea of how long ago it was, i got my filter "system" for $80 and it took a week to get it

 

I thought that I would let everyone know who the contact was at AutoPhysics that set up our group buy.

Skydive69- My guess on the dyno issue would be that the numbers would be within 1-2hp. Every time I have been on a dyno, the vehicle is stationary with the hood up, exposing the filter. With the Airaid box, you close the hood, and the only air coming into the airbox is coming thru the drivers side fender opening. As it comes in it hits the rubber end of the K&N and bounces around the filter. Since these boxes are not truely pressurized, there is still a little lack of air volume getting to the filter on demand. As someone who designs commercial kitchen ventilation systems, I have a pretty good understanding about airflow properties. When you step on the gas hard, the demand increases faster than the supply can produce. As the demand remains constant, the velocity of the incoming air increases due to the new increase in demand. This would help to explain the peak hp being roughly the same, even out on the road, but the acceleration increasing with the open ended filter. When PSP decided on a filter for his setup, I'm sure he tried both, and my guess from looking at the construction of the 2 filters, is that the open ended filter costs more money by itself, by 20-50%. The K&N is a one piece unit with the rubber mouth and the rubber endpiece moulded into the filter. The S&B unit (I have no idea if this is the same unit as PSP uses), is 2 filters, the end cone and the main body, and has a separate plastic and rubber boot that attaches it to the airbox.

 

If i remember the thread correctly,Sal was saying that the airflow around the K&N at high RPM disrupted the mass airflow signal.Switching to a "openended" filter corrected the problem.Gonna check to see if the filter came in tommarrow.Cant friggin wait!!!

Skydive, Just an educated guess, but you can set your filter up on an airflow bench (can use a fan with yarn)and check flow. It's the turbulence or lack of it that makes the difference as well as temperature.

Interesting theories, which probably have some credance. It makes me wonder why a company such as K&N which specializes in making filters would not be aware of those simple things, and assuming their awareness, why they would not have a similar design. I wonder how K&N engineers would speak to the issue?

Back2 and all,

I have retrofitted the Powerstack filter from Autophysics into the Airaid box, taken pictures, scanned them and cant publish them for *****. Red on Red looks good and I want to share the view. Need some help!!

As far as the performance increase between the K & N and S & B, it is difficult (for me) to tell the difference. I ran/tested them both last week at the strip. My times were pretty consistant, irregardless which filter was used. Never fast enough, but consistent.

IMHO, the Gen 2 Lightning has the biggest "issue" with the solid rubber end due the "ducting" bringing the air via the fender combined with the mass air meter being between the filter and blower. The less the turbulance the better. I feel the biggest difference would be at WOT. No flame intended for anyone, just my $.02. Fifty bucks is a tank of gas, a dinner with the Mrs, or a round of golf.

I went a step further and "sealed" the assembly edges of the Airaid box with a thin bead of black RTV (inside). I KNOW you have some in your tool box.

MRBBQ--$80 for a PSP kit and week turn around....You OLD School!!!!!

Go PACERS!!!!!!!

RedisBetter,
Where are you located? You say you have a dyno? When is the best time to get a few pulls? Give me a call if you have a chance @ 633-4132, I live in Taylor and I am in DYING need to get this thing Dynoed ASAP.

The shots look great!!

Looking for a better paying job to support my L

 

I'm on the "job" for State in Texas, my dyno is about 1500 miles away. You will find that most dynos make no money, they are used only as a draw for customers.

There are three dynos in the Cedar Park area and I may work a side job with one of them (been talking to them and waiting for an good offer). I'm, thinking of a dyno day with a shootout of parts. Of course I will let the L guys know. We would be looking at $75 bucks for 3 pulls, with 15 minute cool down and racking I could do 8 Ls in 9 hours. Of course the early Ls and the evening Ls will put out more power due to temp. It would have to be on a Sunday.

As I have already said the dyno is good for many things but better airfilters is not one of them.

Back to the post at hand;
I know Mr. Lum and I have sold and dynoed his stuff on a few Hondas, Impala SS, Ls and he even has one for my 390 GT Pony 4bbl. The powerstack IMO causes less turbulence and thus produces more power. This is really true on any enclosure type filter box as on the L or the GTP. There is a noticeable sound difference between the filters at WOT. There is a SOP dyno difference.

I just got off the phone with the S & B filter people and they said they did not know if they had anything to fit the 00 L or not. Lady said the one they built for the 99 L might work but they were not sure.

 

I installed the Big Mouth filter today and gave it a testing.

I ordered the 10" Big Mouth filter

After the install, I measured the distance between the filter opening and Ford's air hole in the wheel well. It was 3 1/2" directly inline with the filter opening.

I noticed right away that the blower was noticeable while barely given gas. Under WOT is screamed.

I went WOT at different speeds, 20 MPH, 40, 60, 80 and my gut feeling is that the L did pull harder.

Therefore, my conclusion is:
The blower is louder and I think the L is stronger and all for $58.00.

Nothing better than that!!!

yep like I said it is noticable both in power and noise.. but what sweet noise.
