So, you’ve built a hopped-up fire-breather of an a engine, and you think theres not much else you can do to make power. Well, there’s always something to be done to eek that last little bit of power from somewhere. For example, check out Racing Power Co.‘s Super Flow Air Cleaner.

The air cleaner utilizes all of its surface area to flow as much cfm through the carb as possible. Instead of sporting a tin top-cover that we are all used to seeing, the Racing Power Co. Super Flow Air Cleaner takes a different approach. It has a top-cover that is made of the same filter material as the circular unit that sits directly atop the carburetor.

Doing so allows air to flow through the top of the air cleaner – not just the sides. If you think this is a novelty, and purely aesthetic, you would be wrong.

A few years back, our buddies at OneDirt.Com took the liberty of testing this air-flow theory. They started with a factory air-cleaner top, made of tin, and used a 2-inch circular filter, which netted them a peak hp rating of 245.09. Then they used a 3-inch filter with the same tin-top, and got 245.28 peak hp. Lastly, they used a 4-inch filter and picked up another horsepower at 246.3.

Since the best numbers they got were with a 4-inch filter, they used it for the final test. With an open-top air filter – like Racing Power Co.’s Super Flow – they picked up two whole horsepower, bringing their peak number to 248 hp.

If that isn’t a huge endorsement for an air cleaner like this, we don’t know what is! You can read all about their tests and check out their dyno sheets, here.

The Super Flow air cleaner comes in chrome/red, black/red, and black/black for that sinister look. They’re also available in the oval shape you see above, and the round shape you see below. The round version can be had in 14×3-inch and 14×4-inch. All of the oval options are made in a 12×2-inch size.

So, if you’re looking to jazz up the under-hood appearance of your ride, and pick up a few ponies in the process, check out Racing Power Co.’s website.
