Looking through the Screaming Eagle Pro Racing Parts catalog at the different A/C versions offered, I'm left wondering what performance level (air flow efficiency) each offer. Do any one here know? Are they all the same?
Maybe list them in order of performance level, i.e.(this list is in catalog order, not performance order):
SE performance air cleaner kit 29400232
SE heavy breather 29400173
SE Extreme billet ventilator 29400163
SE ventilator elite 29400217
SE extreme billet air cleaner kit 29400064
Much thanks to any who can offer performance level of each of these.
It would also be an interesting comparison of SE to non-SE offerings...

Note - I previously posted this in the General Performance forum but got no response. I know this isn't specifically on-subject here in the ECM/Tuning forum, but being closely related is the reason I'm asking the question. Thanks in advance for your opinions.

 

I don't know if or where the info you want can be found. You didn't say what the application will be, so unless it's a big build it probably doesn't matter.
Since they all will flow more than enough for a stage 1 upgrade, the only difference is appearance.
My 2 cents on intakes is to go for one that has external breathers. I got tired of messy blow by and the thought of that hot oil getting sucked into the heads, so I went with a DK Customs 587. It will give you plenty of flow, keep the bike and combustion chambers cleaner.

 

I appreciate your input nevil.
The application is my stock 2016 ultra limited, headed toward stage 1. Presently the only mod I have made are SE street cannon slip-ons, but I'm planning Rhinehart true dual head pipes and their slip-ons, and I have a power vision tuner on order. I don't have the extra cash to buy it all at once, but I see the tuner as the first thing I need - that way I'm ready for whatever I add down the road, expecting that the a/c will be my next purchase.

Get the one that looks the best to you. You won't be able to tell which one performs better.

 

J929626, thank you for making me aware of that thread, it was very helpful.
I appreciate everyone's input!

 

We like to and do use a filter set-up, that does not inhibit the engines breathing ability, for the intended application.

Keep in mind that and air cleaner has 3 basic functions. It must provide.....

Clean air flow

Laminar air flow

Cool air flow

Most Harley air filter designs forget at least 2 of these. I do like the Harley Heavy Breather type design. Most suck air from either the cylinder cooling fins or from the air flow that just left the area near the front exhaust. Most are way too short to provide laminar flow. Some designs forget all about the clean part. Go figure...

Hope this helps

hillside and whittlebeast what are your recommendations for a stage 1 that meets the three basic functions and doesn't restrick air flow?
I have 2014 Ultra Limited!
Thanks

 

Harley Heavy Breather type if it fits in the tupperware and sucks cool air. The 3 rules do not change, no matter what stage.
