@@woods-garage I came to the comments to say this exact thing. I worked at a local drag strip for a few years and watched many 1/8th mile index racers looking for 1 tenth or so and can't find it. Then they slap an air filter on and break out by a tenth+. It's crazy that the things they we assume will hurt power will actually help make more power.

[@GNX157]

[@burgerliker11]

Steve, it actually makes a bit of sense that the filter helps it. If the filter is super non restrictive, I could see how it would improve. Think of a gas lense in a tig torch. It evens out the airflow and causes it to be laminar instead of turbulent. In this case, it’s probably smoothing out the way the air is entering the carburetor. With the amount of air that engine is moving, it’s almost definitely turbulent due to the air velocity. However, not all turbulence is the same (think small and big bumps when riding in an airplane). If it’s reducing the amount of turbulence entering the engine, the fuel mixture and distribution are probably a lot more consistent and evenly distributed due to the lensing effect of the air filter. Interested to hear your thought on this idea.

[@bigblockjess617]

The filter allows just enough airflow to slow/settle down for it to be more evenly distributed throughout the intake at the same time allowing for fuel mixture to optimize more evenly. All wile creating a bigger vaccume

[@papaburf7275]

Agree with the smoother air flow comments. With the filter media I believe the air flow gets very laminar and the engine is able to digest more CFM as a result. Love your content - thanks for sharing.

[@JimMcCann500]

More Ford Content! Great feature. People constantly overlooking the BBF in favor of the BBC, it's the hidden gem of the motor world lol. I would also say a few things with respect to the power gain: 1) did you run the "Base Combo" again? I would be interested to see if it picks up power after a few runs warming the oil and settling the cam and rockers in. 2) One hypothesis is that the Filter acted almost like another manifold, slowing or sort of trapping air and therefore making it easier for the carb to pull it through. I see you turned the fans on right before each run, they appear to be pushing air out of the room? If that is the case that would also pull air away from the engine (which would make sense that a large filter which traps air and slows it down would make more power)...This affect would probably happen even if the fans were pulling air from outside and pushing it into the room. I could also be very wrong though. Great video either way BBF FTW!!

[@vasiliosvavasis]

The inlet manifold may be a little excessive for the application, and once the filter is applied, it creates a better Venturi effect, causing the power to be increased

[@mcintyretyler89]

It stabilized the air atomizing the fuel better

[@scotthultin7769]

It straightens out the air flow to curve down in there because of the base plate of the air filter housing

[@rickbrandt9559]

more than likely forces the air to come down straighter ,reduce turbulence over the radius, changing approach angle entry into cab bleeds/boosters!

Less turbulent air. Directs flow of the air better.

Back in my supermoto days there was a saying for the guys that ran no air box just filter. Because it literally was proven to slow you down. The air box would provide "cleaner air"

[@SpiveyNatas]

I believe having just the base on would be creating a better path for air into the carburetor. Then adding filter could make the air entering more uniform and can syphon the fuel better. It might also help how the fuel is mixed into the air for better distribution to the cylinders . I wonder if the EGT temps were more even with the filter. Great stuff .Thanks for sharing.

Maybe by putting the filter on it creates more vacuum at the mouth of the carb and cfm goes up. Just a thought

[@gailtaylor1636]

Watch how much the filter "sucks in" when under load. I'd be little concerned about the filter getting sucked thru the carb when it implodes.

[@Roush150]

I’d be interested to know if it’s possible to do is put a vacuum gauge on the hat with the filter just for curiosity

[@larrymccandless8723]

Stated in other comments also, buy my idea is that w/ no filter, the area an inch or so above the venturi's is very turbulent and the filter prevents the air from getting 'dirty' just before it is pulled in the carb.

[@jidean2012]

The filter smooths out the airflow.

[@strykerentllc]

Dewey must be on vacation. 😃

[@trickyhickey69]

The restriction can easily affect the atomization of the fuel. A little restriction isn’t always bad with carburetors.

[@matthewmoss222]

The air filter with a well designed base plate is shaping the air allowing smooth transition into the carb.

[@ridemotoeveryday]

Kinda what I’ve learned just messing with dirt bikes. With a filter it creates a little more of a vacuum effect in the carb pulling more fuel volume through the jets. Also smoothing the pulse creating a more consistent flow for the venturis to work. As long as the filter isn’t restricting the amount of air needed to match the fuel it usually picks up power.

[@mooklocklear1182]

I love that setup and that bbf just wants to keep clean air lol

[@danieleves3403]

I reckon the filter smooths the airflow out, giving it a better velocity through the carb.

[@vinceallison1028]

It makes you rethink the old spiral windvains in the intake tube trick.

[@fordmud]

I know air flow into the carb makes a huge difference. As in the way it swirls or the direction it enters. That air filter probably straightens the air flow and coming in from the sides through the radius base plate accelerates the flow, rather than going straight in from the top. At least that's what I've noticed about airflow.

[@wfoguy]

Back in the 70's, it was a know fact that a radiused base going into the carb helped. As has been stated, the flited probably isn't causing a restriction. My initial thought was reduced turbulence going into the carb. That may not be correct. What is the filter allows a swirl and accelerates the air speed. If you put a vacuum port on the top of the filter, it would be real interesting to see how much vacuum there is versus the vacuum in the manifold.

[@george1la]

Amazingly smooth sound at 9,000 RPM. You are not thinking about the combined effect between the shapes of the bottom and top of the cover holding the filter. It is obviously aligning the air, probably more laminar flow by eliminating turbulence.

[@larryjasonmoore]

Started the stream with a dyno pull and my sound at full volume in my headphones. Thank You Steve!

[@evanmyklebust3265]

The filter is changing the signal over the Venturi in the carburetor and is allowing it to work more as designed.

[@garyschroder7444]

Like others, I believe there may be air vortices when run w/o the base, and the base smoothes out the flow and then the filter adds more favorable smooth air flow.

[@randallbernard2074]

It Straightens the air, less Turbulence

[@adamfournier6735]

My guess is that the filter smooths and aligns the airflow, acting as a bit of a buffer to changes in air flow around the engine. Very neat though.

[@Speedie15]

I had a 2bbl claimer engine that picked up 3 when I stacked a cpl of air cleaners on it. And another one with a proper tall filter. My theory was that the tall filter provided enough air to not be a restriction but cleaned up the turbulence into the carb.

[@budddove6480]

Ive actually read some awesome studies about this very thing back in the day. Theres been tons of research done about the effects different filters have on the fuel delivery/atomization through carburetors. Its amazing how different filters, spacers, and of course intakes effect atomization of fuel. You can adjust a spray nozzle into a perfect mist, but when you spray it into a fan on high, everything changes. Sorry to ramble, just a very interesting subject i dove into years ago while dirt track racing. Every little bit counted when it came down to the stringent rules given for the class i ran. A good filter will actually help power by improving the atomization of fuel delivered by the carb. A nice clean burn is good for power. That can be achieved by stopping turbulent air and cleaning up the delivery. Lots more goes into this, but thats a very quick amd dirty synopses.

[@singlefase1]

The air filter is a vary small restriction witch causes laminar airflow.The venturies respond with better atomization and distribution increasing horsepower. Nice build !

[@user-ps8fp8kb8j]

With limited air intake (one carburetor) you get very high speed air which can cause some "stand off" and air disturbance above the carburetor. I think the cover over the top of the air filter and the quality filter are helping "smooth" the air flow which is giving a more consistent signal to the boosters in the carburetor.

[@hk45c62]

K&N had those carb velocity adapters, back in the day, for carbs with and without a choke. I tried one and definitely helped my car run smoother while cruising.
