Shorty Pod vs. "Regular Sized" pods?

Coast to Coast
1. What is the difference between a Shorty pod (pictured below) and a "Regular Sized" pod aside from the size?

2. I like the fact that the Shorty is smaller and more minimal, but performance wise, is there a difference between a Shorty and a larger pod?

3. How about intake roar? Louder with the Shorty?

Thanks,
John

Those are trash.
I know I sound like a dick but I speak from experience. If you want pods you have to spend the money on a quality set of k&n or uni filters.
The universal emgos kill performance, shorty or not.
 
I think the question boils down to how does changing the surface area of the intake filter alter performance? Clearly one would expect going too small would cause problems, as it restricts the amount of air able to be sucked in. But, can going to big cause problems also? Does the surface area of the filter need to be just as big or bigger than the intake bell of the carb? Is there a ratio one needs to maintain to account for the media of the filter?

I've wondered this myself, as I run 6 inch long UNI foam filters that have no caps. They're just massive sponges, with filter oil on them. I always figured bigger is better - give the engine as much air as it wants without restricting it.

If I was dealing with space restrictions, I'd for sure go with UNI foam filters. They'll offer the most air flow for a given size vs. fancy looking filters with chrome on them. Plus UNI are cheap AND good, not a common combo.
 

I'm guessing he's neither.....probably trying to stop the whole 'Hipster baiting' that's been taking place on DTT recently. Tell OP a valid and usable piece of advice, or GTFO.

I was agreeing with SONIC, if my statement came across differently it was not
intended to and I apologize for that.

If you think about it though, the inlet hole is the same either way (of the carb). So it's just a matter of when the air is getting filtered whether it be further away with a longer pod or quicker with shorter pod?

no
the air in that small pod has got to make a dam near 90 degeree turn just before it is asked to do its work
look at it as if you were trying to force water thru the pod you will see all these little tiny streams running in and bumping into each other
iits the same with air it is going thru the screen at the most comfortable angle which is not headed towards the carb mouth
when the filter is further away the air has a chance to gain velocity in a much smoother stream, this matters, a ton pun intended

Aha. Very true. Thanks man! Makes sense. Living and learning!
 
pj certainally does have it right as far as those detriments he points out
i am focused on the other issues of having a restricting,air tumbling device so close to the intake carburetor bellmouth and venturi area
also it helps if a person keeps in mind that the engine is NOT sucking in air,it is only creating lower pressure and atmospheric pressure(about 15psi) is what is FORCING the air in,form outside the engine
bottom line is any RESTRICTION like a screen,pod or a filter(which they all are) ideally will not be so close to where the air is trying to march in ,in a nice straight formation,like an army of marching molecules all packed together in a clean formation this is what we want not to have them slowed down,stumbling over each other at the door,not letting as many in as you could

Hard to tell from that picture but that shorty looks like those tiny ones use on crank case vents.

I'm pretty sure that is because it is a crankcase filter..
