(MAX #'s may not reflect from charts below because the MAX
may have been between the 100 RPM increments shown. MAX TQ
#'s are slightly low due to the fact that peak tq occurs at
approx. 3250 and all runs were started at approx. 3500. I
assume MAX TQ #'s would have been approx. 5 higher or more.)

After this was all said and done, has this settled the big air filter debate yet? Possibly, possibly not. I believe '99 and '00 Lightnings may respond better than an '01 to K&N panel filters due to the fact that they aren't as efficient via the intake track. Since the '01s have less restriction over the '99 and '00s, then the K&N panel filter upgrade obviously isn't worth much for the '01.

One thing we can gather is that the K&N filter run does work best out of all the 3 runs, although the difference is very small, and for $40 you really can't beat this fact and the fact that this filter will last a lifetime. Another thing to note, though, is that the factory filter will perform better than no filter at all, so don't go to the track and remove it thinking you'll gain performance.

Something else to notice is that the K&N filter run actually puts a hurting on the other 2 runs from 5300 to 5500. This gain is good enough for a performance increase on the track so long as you shift your vehicle at 5500 or higher.

Some of you ask how did you get I get my truck rpms that high w/out a chip? Well, factory fuel shutoff is 5500. Though, I would not recommend shifting your stock programmed Lightning yourself, but allow the computer to automatically do it at the 5250 mark (basically put it in D and leave it there).

When you become chipped you will DEFINITELY gain performance by having your tuner program your truck to shift at 5600. Up to 6000 would most likely give you even more gains, but then we're risking possibly too high of rpms for shifting on the stock internals. The theory behind shifting higher on our Lightnings (or any other vehicle) is simple:

You always want to be in the gear with the highest horsepower, as at any given speed that will provide the most rear wheel torque. Or explained easier, the trick is to minimize the change in momentum, so you pick the rpm that changes the least in hp when you shift.

I hope this helps everyone! I'm going to continue doing this as I add on additional parts. At $75 bucks a pop (dyno time) it's going to be expensive, but this is something I love and and want to do. It will also help all of you out in the future by giving you ideas to help in your decision making.

I will get some .gif image files up of all the graphs sometime tomorrow, and a comparison of my '01 to my friend's '99. My floppy disk was bad that I took w/ me to the dyno to get my Pep files so I can view and compare them, as well as others, in the Dynojet Run Viewer (which this is FREE, and you can get it here: http://www.dynojet.com/downloads.shtml , so MAKE SURE YOU GET YOUR PEP FILES FROM YOUR DYNO OPERATOR!!!). Doing this will allow me to make .gif image files that are perfect in quality and extremely small in byte size (approx. 10kb each), and keep from having to scan the print-outs in (which usually result in poor quality and huge files).

Take care and God bless!

...I used a BIG industrial fan in front of the vehicle about 3 feet away. It had enough air flow to nearly push you down. Sure, there is a possibility that at highway speeds the cooler dense air may help the system, and then which one would win? I'm just giving you all an average of "drop-in" replacement gains.

I don't doubt that the K&N Panel Filter works for our truck, but I'd like to see other dyno's on '01s under the same circumstances as mine so we can draw up a final conclusion. If you have your #'s please post them. And I don't mean "peak" #'s either, as we need entire graph #'s, particularly like mine from 3500 up, before we can make that assumption.

Thanks for the info....too bad you did not have a conical handy...

 

what mod are you going to install next? and which tuner are you going to use? this is interesting for me., thanks,,,,,,,,,,,,,,, al

 

Anyone going to give me any praises or any "Way to Go!"..."Good #'s!" ???

I think this is a REAL test that needs to be noticed. Tapping fingers waiting impatiently (LoL).

BfB

 

"Way to Go!"..."Good #'s!" .....

 

Bubba:

Good work, Chief. This is the kind of testing that we need to see more of. Right on the money. I have to say that you settled the issue for me, unless someone comes up with some VERY convincing contradictory information.

I'm going to go to a happy place now, curl up into the fetal position, and whimper.

 

good reporting--useful info. But really, is it Auburn or Alabama?

Dan

 

You always were/are a hot dog for attention... Most of the time you just talk but now you came through. Nice numbers on your stock/slightly modded 01....even if your numbers are lower than mine with the same mods.....lol

 

Hey guys, sorry about the Pepviewer not having directions. It is in DOS so what can you expect from them?

Anyhoo, here's what your directory structure should look like:



Quick Instructions:

Make the following folders and subfolders w/in your "C:\" directory. Only difference is that you'll need to also make yourself a very last directory in whatever 1st directory you place it entitled w/ YOUR name, NOT my nickname of "Bubba", LoL.

THIS PART IS CRUCIAL: Make sure you place your Pepviewer.exe file you downloaded from the link above w/in the 1st directory (I named mine "Dynojet" but you can name it whatever you wish, just as long as directory structure holds true. You will also need to put any pep file w/in the 3rd (last) directory w/in the directory leg you're wanting them in.

Some of you all will share pep files (I will, doesn't bother me) so if you want mine lemme know. I will not have them until later today. Then you would make a "Bubba" 3rd subdirectory as shown and place mine w/in those.

Now, just play a lil bit w/ the viewer program and you'll have it down pat in no time. It's simple, so don't let it beat you in the heads.

My site is down temporarily so if you can't view the image file I made of how the directory structure should look above then click here on this attachment:

Maybe the stock filter setup flows enough air for the stock boost level, but if a pulley is added...I think the engine will need the extra breathing from a conical filter/ram air. Just my opinion though...dyno comparison's like this are always interesting .

 

Those numbers sure beat the hell out of my 99' 4.6 F-150. haha. I only wish I had me a "L". Good info man, keep it up. and thanks.

 

I installed a K&N panel filter in my 01 L and noticed no difference in power nor boost. Now I did notice a difference in power when I installed that huge *** 12" conical filter, no doubt. I also saw an increase in boost along with the sweet sound of whining

Very good info

 

Was your airbox modified with the 4" cutout and tubing? Do you think the industrial fan would allow enough airflow into the box as compared to a modified box? I'd like to see if this situaution would have any gain/loss to show. Again, I commend you on your work!!!! Hard facts are the best facts!
