Let me show you one tiny tiny example of what I'm talking about here ...
This is a Hypercharger, compared to no air cleaner at all.
Now you could argue that up to about 90hp, the loss from the Hypercharger is not significant.
But if you've got a build that's capable of 107hp, and your choice in air cleaner takes 6hp off that number, that's a big, big deal. The farther you move up the power scale, the bigger the deal it is, too.
I've done lots and lots of dyno testing, and in many cases, I've tested exactly what I show above. In other words, I'll tune and test the bike both with and without it's air cleaner in place, to see how much the air cleaner is costing me.
One pattern I've seen repeatedly in doing this testing is that there's a very high correlation between the power level the air cleaner will support and the surface area of it's filter element. Those two things are generally tied together. The bigger the element, the more power the air cleaner will support before it starts showing a significant loss as compare to the open, no air cleaner configuration.
Air cleaners that introduce a longer intake length, like the Forcewinder for example, tend to give a pull at a specific rpm range, and in some cases they can actually exceed the no-air-cleaner configuration over that specific rpm range.
I love this topic. No one will ever convince me that one AC is better than another. Think about it your carb throat is only so big and unless you install a turbo charger your carb will only allow so much air to enter. The filter may be different and allow more air but thats all. So pay $500 or pay $39.00 like I did and I will race you.
^ Exactly! Ness, K&N, etc,, try to convince the public a washtub-sized cleaner will instantly transform their Harley into a Isle of Man rocketship. It won't.
What I wanna know is it seems to me the scoop design of the SE intake potentially can force alot more air into the intake than any of the Ness or K&N designs can. Screaming Eagle design engineers know a heckuva lot about what works on HD engines.

Right. The more I analyze the 'more power, more power, more power' conundrum the more it seems misguided as to what a makes a HD a HARLEY DAVIDSON. IMO it ain't drag racing which is why the V-Rod project failed. Sure power has its place I'm not saying it's not important but it's far from the whole pie...its just a slice. One slice out of several. I don't get guys wasting thousands of dollars on Hammers or S&S & then getting dusted in a real street race by a stock 883? And it happens...alot. This eye opening video that everyone has a seen is what I'm talking about: https://youtu.be/BFzhc3i0PRY
Apache it looks like you've already spent it on the most important mod you could...PROGRESSIVE shocks. The other $2k+ you dropped is IMO very secondary as to the amazing difference PROGS will make from my experience. Even then the majority of PROG's benefit is thankfully limited to the rear which is laughably easy to install compared to a Softtail's monoshock which is a bit#@ & a half to install in your garage. If I had the cash I'd probably just drop it on the rockers, lifters and intake/throttle body work which should totally cost more than $750 right?
My honest opinion is you can't go wrong w/ anything SCREAMING EAGLE (intake, pipes, cams, lifters, intake.)
As the vids I linked demonstrate you CANNOT buy what time in the saddle learning how to ride will deliver in a real street race. Drag racing is for 15yr olds and GED dropouts. It requires nothing but a full throttle and hanging on. Canyon carving, on a HD no yet, can only be acquired by growing elephant kohonas and skill honed by multiple near death walkouts at 55mph on canyon roads & narrow turns in city traffic...IMO. Btw I'm far from ^ elephant ball's skill level in the videos but I can appreciate & admire it while realizing it CANNOT be bought or sold by money hungry liars.

Been riding since 1960. Never been down on the road even riding with reckless abandon back in the day. I believe I got this down. I'm pretty sure I'm going to make it. LOL I'm done here, got bigger fish to fry.

Lmao 🤣
How about we both buy brand new Sportsters. Same models. You drag race my 15 year old son and the winner keeps both bikes. One race, best of 3 or 5. Your call, you pick the track and dealership for the new bike purchases. 😁
How 'bout you find someone else to concern yourself w/ since it looks you don't have much going on to follow me around the forum like another internet loser. IDC what you think of my opinions. Move On!!!
