 Subject: Air Filter Question
IP: Logged
Message:
I am doing a Senior Research Problem at school and I am testing different brands of air filters. I wa wondering what would be the best way to test amount of air flow, how much fuel each one saves, and horsepower gains(can't use a dyno)? Any help would be greatly appreciated.

try 0-60 times to check, should possibly change with the different filters, but may not. just a thought.

Yeah, we thought about that, but a dude at the local racing shop said it would differ vary little from filter to filter and it would be hard to tell. Somebody mention something abour using a vacuum cleaner and doing something with it, but I'm not sure what.

Depends on how much time you have. Since you probaly dont have a test motor on and stand and a dyno at your desposial try then. Buy 3 or 4 aftermarket filters, use the stock paper filter as your control. Then use each filter for a full tank of gas to get fuel milage. If you wanted to spnd some money there are companys that have little computers that plug into your cigerette lighter that will give you 0-60 times, and hp/tq ratings.
What school are you going to?

Test driving on a tank of gas per filter is not going to give you a very accurate test. You'd have to drive the EXACT same to get true results.
For testing the air flow, set up a simple test where you blow air through the differnet filters. You can set up a box with 2 holes, with the filter near one. Blow air into the box through the filter and out the back hole. You can try using some movable object and determine how far you push that object from its starting point. maybe a checker? You would of course need to control the amount of time the vaccuum is blowing air.
I can't think of an easy way to guage fuel/cost savings without using a dyno or "lab" test vehicle.
I never did projects like that in school.

An open element air filter with the K and N air filter will flow the best.

for the flow u do what 00dak did but instead of using a moveable object or blowing through small holes u have it blow out straight and use a little meter that shows the cfm of air and move it around the filter to get an average cfm flow
For gas savings u could always take an old lawn mower or something and rig it up to a device that measures distance (like an old odometer) and put in 1 gal of fuel then run it in a controlled climate until fuel is spent

you must be an idiot if you are coming on here to look for answers for a SENIOR design project. try thinking it out yourself.
most likely wont be able to do any tests on the vehicle to get any kind of repeatable results. try making a different setup.

There is nothing wrong with asking for help when you need answers. I have the project idea, I just need ways to test it, and there are people on here that are a lot more experienced with air filters and engines than me.
Thanks 00Dak, Dan M and Just Looking for the ideas, I will probably use them.
And 00Dak, where could I find one of those meters? Oh, and I go to the Piedmont Governor's School for Advanced Science and Technology. It's basically a school for people who want to get a jump on college.

Wow, your project will be tough,but I picture a ping pong ball inside a clear plastic tube, a leaf blower blowing through a "filter housing assembly" which is then blowing into the tube, pushing the ball up to a measured level....change filter brands,designs and sizes to record your data..........ry is rude and his statement was totally uncalled for.He must immediatly appolligize or may all his children be born naked!

Don't worry, there's always anal retentive jerks that make threads miserable.
You could make your own flow bench, but it takes a bit more than one vacuum cleaner. It takes about six vaccum cleaner motors or two high power leaf blowers. I'll see if I can find you some plans or you can search the internet. I use a friend's homemade flow bench and while it doesn't give direct readings, percentage increases and decreases are very accurate. You merely have to establish your own standard.

N56629 summed it up best. You need to establish your own standard and use it for all tests. The key is to only vary what you are testing, in this case, the filters. So every test should be ran in the exact same conditions and methods.

Here is a near duplicate of what I have been using. There are no plans, but it's a very good discription.

It might be possible to simply place a hot wire manometer between the filter and intake. If you have a friend in the HVAC biz, you could get some ideas there.

Thank You N56629, the diagram you gave me is just what I have been looking for.
