The heavy breather smoothes out the air prior to entering the engine.  It has been proven via Dyno run that you will get a couple extra horse.  Dont know if it is worth the money for the heavy breather.  I do know its worth the COOL factor!  Gives that nice" I'm faster than he!!" look.

A couple of HP's for that kind of money could be spent somewhere else. Fullsac Steve says the stock SERG filter only cuts about 3HP vs no filter at all. So the Heavy breather to add anything would suprise me. I do not believe the smooth out the airflow deal, the sharp bend would disrupt it more than a couple inches of staight could smooth, but if you have the backing plate chromed it does look cool. Someone on here mentioned Ram effect, the end of the filter is blunt, how could it Ram anything? But it does look cool.

I wonder if the air it picks up is cooler??

I do believe that is on a stock engine.  I thought their was a little gain with the heavy breather if you had removed the cat, fullsac baffels and a map.

Seems with his latest update, the Anderws 54 cam, thinner head gasket he added the heavy breather to make the big torque.

I could be wrong, but I will be talking to him about that cam and map...Sure had nice curve on the chart..

I wonder how much the thinner gasket helps the compression?

Quick questions for all;

Is anyone running the Heavy Breather (HB) with the lower fairings? 

P&A Book states the HB can't be used with glove boxes.  Anybody running with lower fairing glove boxes?

On my scooter I'm also trying to kill the heat.  But, I won't give up the lower fairing.  The 49-96 catless head pipe made a large improvement in heat reduction (Preception, not measured in any formal way.  And, my seat say's the torque band moved south.)

The way the air flows with or without lower fairings onto the front jug and then bypassing your leg, there in other place for the hot air to go but by the headpipe and then under the football AC.  Which heats up the football. 

I'm just waiting on the breather bolts to arrive and the HB will be installed. 

But, that does bring up another question.  As we're not changing the throttle body, the only advantage I see is probably a cooler air source in front of the headpipe flow.  And cooler air doesn't really appear to require a re-map. 

Is anyone running stock with the HB?

Thank you.

Great News.

For 2010 The motor company got wise after all the call I made to the regarding my 2005 SEUC with lower faring.

They just came out with the Heavy Breather for lower fairing, and Yes I have see it in action.

Here is the part number for the full kit 28716-10 Chrome Compact Design $299.95.

It you want to add lowers and already have the heavy breather you will need this part number to replace the filter element to the shorter to accommodate the lower.

That part number is 28714-10 Retail for $89.95. Is on backorder to Mid September.

Additional information can be found in the 2010 Screamin eagle  Pro Racing parts book. page 25.

good job Terry, looks good. 299 less 20% and no tx, = 240
might do some heavy breathing

It's a pretty easy install, just a few beers is all it takes

Here's an alternate answer for the fugly back plate...Kury makes it.

Another view: part # 8657...$79.95

Someone had their's sent out and chromed... there are pictures somewhere on the site. That was me, I sent the black back plate to chrome masters in Tenn. Great job! I will take pic tomorrow and post them because I know.

Just a comment on the heavy breather. Jamie at Fuel Moto claims back to back testing by his dyno and also by other dyno's he communicates with show no gain from the heavy vs the stock set up. I'm curious if any one can dispute this with there dyno runs?

I hate to say it, but that doesn't look any better than the stock black piece...in fact I think it's fuglier!!

Kuryakyn really can't get over those big, rolled, folded looking covers they've been doing so much of the last couple years.  Have to assume some like the look as they do keep making them.  But as a stylistic theme it just ain't my thing.  Get the stock ugly black plate chromed.  It'll actually look like it belongs there.  Unless someone likes the Kuryakyn piece.  Then it's good too .
