Everyone will do what they want with their car. Me, I've done the back to back testing on all my engines in all my cars and an air filter not only effects performance, it can effect consistency. That said, you won't find an air filter on a Pro Stock car, any heads up cars and most Comp, TS and TD cars and many SS/T, SC, SG, SS and stock eliminator cars too.

Again, If you're worried about stones this is what you use

What were the results? How much did the air filter cost in ET/MPH on your dragster?

Tony, I don't have the time slip in front of me but I remember it was over .5mph. I'll post the exact results when I get to my race computer/time slips.

Thanks Ed. I have been using the KN cone filter kit that I linked in a previous thread for a few years. I can set my carb idle with air cleaner off and always have to adjust when I put the filter on. That alone tells me it is affecting air flow at least at idle.

I would never run it with no protection from debris but damn sure not going to Home Depot and putting screen door mesh over my carb like I have seen done although that is better than nothing I guess...

It is good practice to replace all of the fuel lines every few years, they do not last forever and start coming apart. Regardless I would try to find where that stuff came from. And the hoses are very possibly the problem.

The fuel lines from the cell to the regulator on my Firebird are 17 years old and again, my filters always look like they just came out of the box. Vern has a fuel source or storage issue.

Tony, that's the filter that killed over .5mph on my dragster

Wind conditions will affect my ride by .5 mph. Was this one time slip or a statistical grouping?

I've been doing this for a little while and have made more passes than most here, I know how to control my testing. You can't get down the track with tire issues.

Dave,

I’m confused a bit. I assume you were talking about Ed. I do run an air filter and two fuel filters. I use the big K&N tapered air filter and the one I posted of the big Ron’s fuel filter and a small one on the line to the Primer Plus pump.

I used to have a filter on the fuel cell vent line. I increased the size of that line and removed that filter according to Ron’s recommendation. After seeing more crap in the big filter I will be adding a filter on that vent line.

My point is still that you need to run a filter. Where we live the wind blows. I also disagree with Ed on the air filter deal. I don’t care if it slows the car down some, out here I’m using one. Good luck to everyone on whatever they decide to do.


I think you are doing the right thing running an air filter. I do not because I run an Enderle hat injection and it is not a good option with those.
With a carb your cylinder walls, valve guides will look better and your air bleeds will stay cleaner with a filter. May cost you a little ET but we are not Pro Stock looking for every penny we can get.

The FACTS and the TRUTH...SCDIV1 built/freshened, ported the heads and manifolds on 468 BBC from 1999 to 2008 and there was never a sign of excessive wear as a result of never running an air filter on that engine and it was raced in dusty conditions throughout it's life. Further, up until 2008 when I sold my Chevelle, there wasn't another n/a Chevelle/GM A body in Division 1 or Division 2 for that matter with a 468, 496, 502, 540 and GM's 572 that could touch it despite everyone of these A bodies weighing hundreds of pounds less.

I will say this about the fuel. I used to run Av-gas back in the day out of the tank from the local airport. I also used to run VP C-12 and now with this car I run Sunoco 112.

I have seriously considered switching to VP but it is a pain to get in our area. I have to drive to Lubbock in order to get it and it is drum quantity. The five gallon cans of Sunoco cost more but seem to fit my program better.

May have to consider switching to VP. I will pull the filter and check it mid season and see how things look. I will also probably pull the tank and flush it since I almost have everything off anyways to replace the lines.

Ed, dusty conditions are when the cars hit third gear you can no longer see them! Big Grin

Vern, I have run Sunoco Race fuels...purple, blue and red for over 30 years and until 2019, my fuel was pump from large tanks into my 5 gallon jugs at the tracks I competed at. Again, no filter in any of my cars over 3 decades has had any debris no mind ever look anything like your filter.

To the OP, I would be checking your fuel barrels. The liner that is used has a limited life and will break down. A Renegade dealer out here was using old barrels for their bulk shipped fuel that cost me a rebuild on my Book carb, a new Magna 500 pump and of course all new fuel lines to the tune of over $2000. When I called Renegade they told me that barrel should not have been used. They sent me 2 brand new barrels of fuel.

My fuel filter looked at least that bad or worse....

Provide some proof & not riding on you sons coat tails either.

Mine are setting on the mantels collecting dust. Keep talking about things you don't know.

For those that use a K+N type pleated filter, do you oil them with the spray type filter oil and clean them with water based cleaner periodically?
