A lot as it will do nothing for power
Much like those funny vacume operted butterfly door things.
They do empty the wallet and they look look cool to the novice that has limited understanding of the whole IC engine VE

Proof is on the dyno.
I do not know if i should cry or laugh every time i see those high dollar butterfly operated things.....
Someone did not understand , or thinks vacume operated butterflys will give more power......

A Hiper charger . Thats what i am thinking of.
250 bucks of bolt on nothing.
So if you bought one please do not be insulted.I am not trying to hurt your feelings .
Next time ask.
Its very hard to "bolt " on Horse power.
I think they made those things to look like funny car fuel injector units for the roots blowers.
A Harley runs under what barometric P God gave us all.
Suck ,Boom Bang method. (about 14 lbs @ sea level)

I always say-If a vendor is going to sell a said performance part it shall or shoud be accompanied by a controlled dyno report.
How else do they know what they are selling?
How do we know what we are buying ?
Why is that asking so much?
Very few air cleaners alone will do much for more pwr.
Seat of the pants and more noise does not count as a viable constant.
The old S and S air cleaner is supposed to actually offer real results. (The one that comes with a Super E .)
(according to smarter people then I )

.....Seat of the pants......
Lite`n up a little.
For many of us, for many reasons, a dyno is not an option.
In the early days seat of the pants is all they had.

Does a low restriction intake add massive HP? No. Can you get gains? Yes.
With that particular one... :dunno
We know it is the proper blending of parts, proper assembly, correct tuning that give you the gains.
All the while keeping the final intended use of the bike in mind.
Among other factors.

And no one other then you mentioned a hyper charger.
Yes. Those are junk. If you had taken some time to familiarize yourself with other info, posts already on this site you would have found anyone asking about it in particular are quickly told they are pretty much junk and 100% snake oil as far as any performance gains.

Apologies to Big Wood.
We tend to stray sometimes. And call BS as we see it.

In the end, your bike, your choice.
Guess what it all comes down to is not wanting you disappointed in your expectations from a single bolt on part.
You may, or may not notice a difference. But the bike will not run out from under you. Or run 10 seconds in the 1/4 with that simple of an addition.

I did not mean to rain on the parade .
It is very hard to bolt on horse power.
The New fuel injected stuff can be remapped.
BUT
as i understand it most do it the hard way and leave it in "Open Loop".
There is some HP left there...plus the new HD engines run way too hot.
I did it again.off on another tangent.
apologizes .
