I have a 15FLTRUSE, another thread in the intake exhaust section talks about the stock air cleaner reducing torque across the rpm band, and recommends the SE Heavy Breather. Anyone put this on the road glide? Problems with fit to fairing or Knee? What other breather have you used to improve flow?
Thanks

[skratch]

on a bike with lowers, there will definitely be a lack of room with the heavy breather.  you could get it to work if you use the compact filter, that'll leave you about 1/2'' to open the lower fairing door.

i ran that way for a while, but i just couldn't get past the look.  it was too jammed up jelly tight, so i replaced the heavy breather with the ventilator.  less room issues and looked better (imo).  i certainly couldn't tell any difference in performance, but then, my bike was just a 110 with a stage 1.  it was not built, and still had the stock 255 cams.

Is the engine stock, or nearly stock?  If so, I don't think I'd worry about a couple ft-lb of torque.  Trust me, you will never be able to tell the difference with your seat-of-the-pants dyno in normal riding.  The Heavy Breather is not recommended for your bike by Harley, due to the Twin Cooling system as well as the lowers.  Yes, you can make it fit with the compact filter element, but you will have to remove it every time you want to access the coolant bottle.  And all bets are off if you've installed speakers in the lowers.

If you're determined to find a higher flow air cleaner, look to the aftermarket for things like a larger (wider) element for the Ventilator, one of the old style round filters in a high flow version, or similar ideas.  Be aware you will give up leg room with anything wider.  In other words, there is no free lunch, there will always be trade-offs as long as Harley insists on hanging the throttle body and filter off the side of the engine sharing space with your leg.

PS.   If you don't mind rebuilding the engine on a regular basis, I suppose a short velocity stack with a gravel strainer screen on the end might work  .

Thanks, planning on at least a cam if not the full 117 kit with the tts150. The discussion on other thread was lots of torque loss early with the ventilator. Trying to see what others have used with the wet head lowers that flowed and caused less interference to the knee .

https://www.harley-davidson.com/store/se-chisel-extreme-billet-air-cleaner-kit        i have used this on an other bike that had lower fairings with good results, air has a straight(er) shot into the TB... no 90 degree turn into the TB like the AC you now have . HD has a few that use this filter element with different cover styles and chrome

My 15 FLTRUSE came with the ventilator and rather than lose any legroom I modified the cover by trimming off the top and bottom tabs for a non-restricted airflow. Trimmed out the edge with black door edge guard.

interesting... Homer, could you send a pic of this mod?

I had an 15 FLTRUSE, the heavy breather will not fit.  When you add the short cone to make it fit, you gaining no real air flow over the stock ventilator.  Stock ventilator is good up to 118 or so torque and 105 HP or so.  So unless doing cams and so on, the ventilator will be ok.  Ventiltor on the twin cams is a better unit than the ventilator on the M8 motors. 

If you really want more air, Suburban speed makes a lager filter set up for the ventilator, a bit less the money then T-mans set up.  Fuel Moto may also have an option for the ventilator.

So you have tried one ? Please post your results using a dyno sheet.

I just did the same to mine, didnt trim it out at all and it still  looks pretty good. I think I will put some chrome paint on the metal edge where it was cut just to keep it from rusting. May be the placebo effect but it seems to run a little better at higher rpms.

That looks really clean... how did you end up cutting this? What tools did you use?

Their website is not up to date, but I  assure you, It does fit your bike..
I have a friend that installed one on a 2016 CVO Road Glide Ultra. If you install one and retune your bike ,,,, You won't believe how much better your bike will run..

 I put it in my vice with plastic jaw on the outside and a piece of 4x4 on the inside because the jaws wouldn't close. I used masking tape over the area to be cut. Then using a razor and straight edge cut a straight line in the tape to match the sides. Then used the Dremel with a metal cut off blade making small passes each time. After it was cut off I smoothed out the sharp edges with the dremel.  Then turn it over and do the other side. Trick is don't be in a hurry, just take off small amounts at a time. It does remove your warning label.

Thanks for the details - I'm going to give this a shot.

Success - thanks JMK! turned out really clean. I scored a line with my table saw and sled then used a Dremel from there. A little filing and it looks great. I much rather replace my rear tire then to have to go through that again though.
We'll see how it feels the next time I take it out.

[JMK]

What did you think? any better?

[Homer 661]

I couldn't get a picture to load (thanks JMK) but I see you got it handled.

If anyone else is interested, I used a vice as well and started with a Dremel but my patience got in the way and I changed up to a metal cut-off tool and de-burred the edge. Took all of about 10 minutes.

[JMK]

did you notice any difference in how it runs or is it just in my head?

[Homer 661]

It seems to pull harder especially going uphill 2 up. I do have a TTS tuner and Fullsac header and cores. I figured more air couldn't hurt.

Oh no, isn't that the same as taking the tag off of your mattress?   

[JMK]

I didn't say it was a bad thing!

[joejoebobo]

I think it actually does pull harder overall... I have the same set up as Homer (TTS, Fullsac header w/ 2.25" cores)

CVODON, I'm still waiting for you to post your back to back Dyno results comparing the HD Ventilator to the Boyesen Power-X-Intake

[JMK]

Here is what I ended up with. Harley claims its good to 140 hp. The M8 ventilator extreme went right on. $212 bought only the filter and cover. I had to change out the mounting bolts to the intake manifold as the stock ones  were too tall. I need to work on the clamp area on the cover where it clamps on the twin cam back plate because there is no flange on the twin cam plate.

These motors are big air pumps so air with velocity is a good thing however more air and no further tuning can be bad.   More air without adjusting the VE’s can lean things out = heat = bad

Is it in your case couldn’t say, don’t know where your VE’s or how accurate they are, but since you have a TTS you can check it.

Can also check your plugs too

[JMK]

Thanks, running flight recorder and v tune every time i ride until I can get it dynoed.
