explain why gator and nhraformula havent had any gains then...is it engine specific

 

I cant explain theres. could be a tunning deal.

All I know is MY REAL experiences, that I have done over and over.

 

I have done back to back dyno pulls with and without the filter and I only saw gains of 3 rwhp. I can see maybe getting 1 mph by removing it in the 1/4 but I also find it hard to believe that you could gain that much et by simply removing the filter. Either way I will test this out myself the next time I go to the track.

 

dlove has dataloged the car. It pulls 30 degrees timing which it should only pull 28 tops I have two 6" hoses running up to the air filter box. On the dyno you will not get the same airflow. It has always done this don't know why but it's the same regardless of the filter.

 

Dyno and quarter mile, two diff things.

 

u dont gain impressive gains by removing the filter

 

I have little to no gain with K&N filter off

 

I guess that depends on how one defines "impressive".

 

Its a air filter not a set of heads or an intake. Cut it some slack. I use K&N just in case. Maybe you should run a test after 10K miles and see which filter is flowing more air. Like the others said, if you have a MAF screen then just yank it when you run at the track.

 

Good point.

No filter-save $50
set of heads-spend $2300

 

Heads are the gift that keeps on giving

 

I never got a gift I had to pay $2,350 for. Now if someone else paid for them, with nothing expected in return from me, I guess that would be a gift.

 

They are a gift in the sense that their very creation enables us to have very fast cars. So the point is if you want your car to be fast than prepare to spend some money because aside from N20 there is no cheap way to get there. Some of us believe $2300 is a minimal investment considering the increased power it yields when matched with the proper cam. Some of us will never spend more than $2300 during the entire ownership of the car. I don't know what you want from me Tee-Boy, I cant explain it I just cant stand a thread that wants to dissect the performance gains of an air filter. That's me for better or worse maybe next time I will just take my 2 cents and spend it on a air filter.

 

Sorry Had to make it special it was my 40th post

 

is this the test results?

 

Looks like it worked on Karl's truck.

 

same here...back to back runs

 

i spend an hr on a flow machine and ran different CFMs through both filters to show which created the most backpressure/pressure drop...they were about equivalent with the paper filter being slightly better than the K&N...

I could make a long post about it but i dont really thing people are all that interested...

i can prove though that with a lid fully open with no filter... it created around 4.5" H2O of pressure drop and with a filter in place it created 6" H2O...

so unless 1.5" H20 is worth 25rwhp...taking the filter out of the lid is not going to help much at all...

Also these pressure drop values were at 600CFM...the value i measured using my maf at WOT...it was the highest CFM my cam only car saw after 3 runs...

so this also backs up that the filter is not really an obstruction and worth basically nothing when taken out at the track...

 

ok...that may be. not arguing that. Im just saying that i would atleast try it, wont hurt anything. some cars gain, some dont. do a search. i found the same thing when i searched.

 

again... flow bench, dyno--still ain't apples to apples up against real world

a restriction is a restriction. a filter is a restriction.

Does John Force run an air filter?

Maybe Karl needs to have a talk w/ John Force.

BTW,
