Difference between K&N filter versus Stock Filter...take a guess
On monday at work i will run some pressure drop tests on both a K&N element and a stock Paper element...this will be the true test of which is more restrictive and by how much...
going to do the flow at various CFM...
probably 100-700CFM...
REFERENCE: For my cam only at WOT the max mass flow i saw at my throttle body was 330g/s using the density of air you get around 591CFM...
make some guesses i am going to use pressure of inches of water column just so it is more accurate...
Ref again: around 28" H2O is 1 PSI
I am going to guess at 600 CFM the K&N will have around 3-4" less pressure drop...
Hopefully we will be able to quantify these results into rear world hp numbers of some sort...

No it wasn't the conditions. Ran first past 13.16 took out air filter and ran 12.92. I also have a 10 second mustang that has made 400 passes and the camaro is my new project. I've made this same test several times before and have even switched from a stock to a slp lid on consecutive runs with no changes.

both filters flowed about the same if anything the paper filter was about 1 percent less restrictive...
looks like K&N is all marketing...I am going to test at the track too...I am still intrigued with this...

my car has never run any faster( MPH )after removing k&n filter.I have done it on at least 4-5 times trying too squeeze out a higher trap speed.If your running faster without a filter,then clean it or replace it.

well i guess you get more stupid with age because you are not going to get 24rwhp or 2.4 mph from just removing a clean air filter...
if that were true would that be a free mod everyone would do...
gator didnt recieve any gains either...

i have seen the same gains by taking out the airfilter time after time. do a search, many others have as well. and yes I had a clean filter, and I know his was clean as well
