Distance from Air Filter Above Carb to Carb Top??

Thank you. I am most concerned though, with a filtered lid or a flat panel filter directly above the carburetor. No perpindicular flow at all. I am wondering how close to the top of the carb horn/vent/etc can it be - is there a distance.

I have seen the Engine Masters show with the filtered lid and the rest of the air cleaner assembly taped off made the most power along with the salad bowl.

There is air blowing around under the hood. That doesn’t happen on a dyno.

One of the issues with the K&N style lids is depending on the air flow in the engine bay, you can have a low pressure area above the air cleaner. When that happens, and air that goes through the side of the air cleaner will flow back out of the top. You can see it on the underside of the hood because it will actually pull air up out of the boosters and that fuel and air ends up on the hood.

It doesn’t always happen. The only way to find out is to run it and see what happens. And it may only do it at certain speeds. Or it may not happen at all. It’s kind of random because the air flow patterns in the engine bay can be random.
