I have seen 140hp with the heavy breather.  I have used the wider filter but haven't used it on a bike capable of 140 so I don't know what it can do.   It has made close to 130 and it wasn't a choke point.

Harley has a couple more filters that breath from the front that match's CVO rims that I think are better.

1. Waiting for the info on that filter element.
2. Certainly would like to know if There's a K&N to match it.

3. I seem to recall that one of the pro tuner guys around the forums had done actual dyno testing to compare the popular air filters' performance, including the ventilator. IIRC the ventilator stood up very well in the test. I think another AC would actually flow more on the flow bench, but it was academic because the engine being used for the test couldn't pump that much air, anyway. I do wish someone with a dyno would repeat the tests and maybe do it on a 124 to really push the flow requirement.

4. I prefer the looks of the ventilator, but if it is actually a limiting factor on my (currently) 113", I might switch.

I seem to recall the same tests and someone making a custom ventilator with a custom wider K&N filter similar to the one shown above.  Think it was called something like a Plus 1.  Cant find it now with a search,  Bet one of the builders are aware and if its still available.

Looks like no with speakers or radiators and I have no idea why

How does the SE Heavy Breather compare to the ventilator for air flow?

When testing with an open throttle body, the Heavy Breather is a zero loss AC. You can actually gain a couple of points in TQ just bolting it on because of the increased length. The Ventilator is a consistent 2-3 point loss in HP and TQ on a 100 HP motor. I would assume the loss to be even larger on higher HP builds. Depending on cam selection, intake noise can be substantial with the HB. The difference in intake roar between a TTS 100 and a Tman 660 SM was like night and day on my two personal bikes. I may be the only person to notice this as I run my exhaust on the quieter side. I would like to test that 3" Ventilator some day.

Suburban Speed HD has a taller filter made by KN.  You get the longer stand off's as well.  They also have a wider fancy one with the 6 screws on the outside.  You have to call them because it isn't on thier site.

Tilley HD in Salisbury NC. Offers kit with a wider filter.

Can't seem to get a link posted with my phone at the moment....

That's right, phato1.  Don Tilley had a hand in the design of that filter.  I have one on Maybelle.    Later--HUBBARD

I was told that Green Filters also makes that larger filter for the ventilator
But I do not have a part number

Got mine back.

Sounds absolutely great!

Max power 120.08 and max torque 129.87. Have to find away to post the curves when I am back. (Heading to Portugal for 8 days of off road riding)
