I'm running the Outlaw Chrome Cyclone 587 System.




Reasons...low profile for plenty of leg clearance, I like the mechanical look of seeing into the throttle body, like that I was able to color match the back plate, it provides only clean cool air into the engine so that it runs best.

Most A/C systems vent the hot dirty oily crankcase air back into the air cleaner, thru the throttle body and into the combustion chamber. Result is compromised performance, gummy build-up in the throttle body and carbon build-up on the pistons which just cause problems down the road.

 

SE filter with a Paul Jaffe SE cover which I really like the look of.

 

Um no. Just AC or just pipes you don't need to tune, Both and you "might" need to tune. Current factory systems adjust quite a bit to compensate for minor changes.

Now if you add cams, then absolutely. But to say you "Need" a tuner with an AC, a bit of a stretch.

 

Over the yrs of researching and learing, Here are some numbers I've found and keep..


Info the CFM's of different Air filter and how much there Air Flow is


HD stock - 171CFM
Stage 1 Big Sucker - 200CFM
Stage 2 Big Sucker - 250CFM
Kuryakyn Twin Velocity - 270CFM
E-3014 = 248 CFM RK-3009 kit
E-3037 = 301 CFM RK-3910 kit
HD-0800 = 231 CFM SE replacement
Doherty Powerpacc - 287CFM
SE Air Cleaner - 287 CFM
Zippers - 321 CFM
Woods Carbs - 4 models 235CFM upto 340CFM
BC Overflow - 800+CFM


Your actual need is (103 X 5800 X .9 divided by 3456 = about 155 CFM) is what your engine will flow and need..

So if you keep you filter clean,,, anything over 250 CFM will/ should be plenty on stock heads and cams 103..
I went with SE/AC and it works well with my cams and no head work, i did buy a Real K&N filter for it,, Not the HD filter made by K&N,, they are not the same

Thinking just get the one that rings your bell and then make sure it has enough flow..

 

Not into those $400 fashion statement jobs that every one else has. Like to keep it simple and do things myself when I can...

 

Your bike will run with an stage 1 AC, exhaust, and even performance cams. But it might run like ****. Hes got a 2014 so its lean out of the box and adding a stage 1 AC will be even more lean right? The purpose of adding the AC is for performance and looks. Will he get any improved performance out of it if he doesnt tune it? Maybe....maybe not

So yes you are right, you dont "need" a tune for anything because your bike will still run. However, you might want a tuner to gain any performance advantage out of it.

 

That is good information to have. But the late model bikes flow more air than what is listed above. I dont know when they did it but Harley has switched from a paper stock element to some type of synthetic material. I found a test, dont remember where, of a flow test of a later model air cleaner and it flowed very well in stock form. It was slightly over 200 but dont remember the exact number. And this was a non rushmore bike.

 

FWIW, I just had this done by an indy mechanic (along with new slip ons and fuel pak)...he used a V&H naked VO2, with original cover.

 

Probably not, once the ECM self-adjusts.
The engine computer will see a different air filter as a change in air density or manifold air pressure, and adjust for it the same way it does for an altitude change, which it does just fine.

 

Thanks for the input, I'm actually running a PCV . Tuning shouldn't be an issue, leaning towards AN
