Hello,

Curious if anyone has compared airflow between various airfilters? I have a SE Heavy Breather, and am thinking about changing it. I liked the Roland Sands A/C. I'm looking for similar airflow, more is better, and smaller profile. Am I asking for the moon?

Currently running:
2009 FLHX, SEHB, Stock 2-1-2 head pipes, SE Street Perf Mufflers, Andrews 26H, TTS w/ custom tune.

Builder got 100 ft-lbs 89 HP if you're interested.

I just don't want to sacrifice performance for smaller breather.

Thanks
H

 

I've seen threads here and on other forums with cfm for various filter set ups.
All of the most popular including the standard SE, flow more than enough air for most
builds. They will easily handle your build.

 

Send an e-mail to Jamie at fuelmotousa and he'll tell you. He has done more dyno testing than anybody else I know. And don't quote me on this, but I believe I've seen him say that the difference from one high-flow a/c to another is very small, so that if you want to switch out one to another you shouldn't have to re-map.

 

Below is what Jamie said about an identicle question in another thread. Contact him if you've got any further questions. He's someone's advice that you can trust.

You will see very little difference between these 2 air cleaners in most applications. Once you replace the restrictive stock air cleaner with a higher flowing aftermarket unit the air cleaner is no longer the limiting factor restricting airflow in the intake tract. This is something we have tested many, many times on the dyno.

Boyyyyy...
I'd like to pick Jamie's brain on this for a minute.

The Doherty setup comes with an internal velocity stack, if you will.
We all know that a velocity stack forces more air in.

I'd like to get his thought on this.
