Worth it to cut the inside cone out of the air cleaner? Should i weld something in to help dorect air down more?

 

while i have no personal experience, what i've read around here is that removing it makes the engine louder, and is said to improve power a little, as measured by someone else's butt-dyno, a real precision instrument that produces answers like "that felt a little faster"
i'll let those who have personal experience take it from there

 

i deleated mine...when i turboed it...made a huge diffrence...
ive heard it helps, i wouldent expect it to make any earth changeing diffrences. it dose take up a lot of space. i did take the little plastic deal out of the bottom of the bowl when it was still na

 

When i bot mine my soup bowl was not modified but not there at all. no problems

 

I deleted mine, seems a little better, definitely not worse.

 

How is the noise difrence in cab? Do I need it for smogging pourpes? I have to smog it every year

 

Dont need it for smog.. if anything probably makes the puff test easier to pass. When i did mine it wasnt really louder in the cab, little louder under the hood. I cant imagine it has any other use besides noise dampener.

 

I did it to my 7.3

To be honest, it wasn't worth the 5 min it took to grind the bowl off. Didn't really notice a noise change in the cab either. Had abit more intake noise in the engine bay, but that was it. I wouldn't bother doing it again.

 

Rather shocked you did it in the first place.

 

I removed my soup bowl. Not worth the time or the effort. It did make a lot of noise and a shower of hot, glowing sparks, if you like that sort of thing.
I made of video of it:

 

Another thing you can do if you don't wanna grind, and get an air cleaner bowl cover from a van, 6.9 or 7.3 doesn't matter, vans didn't have the soup bowl, they had a restrictor plate on the lower part.


Any 6.9 had no soup bowl, but they had that lower restrictor plate.

 

The people that get a decent benefit from this is the people who have there fuel turned up and they need more air I'd bet. This would probably reduce there smoke and help burn more diesel.

 

lol was that to keep em from goin to fast

 

its my understanding that the na 7.3 will only flow 340-380 cfm...the resrictor plate is to reduce noise from air pulse at low rpm... like baffals in muffler.. on my van left it stock just made sure the cold air intake pipe was hooked up ...if somebody came up with a way to turbo a van i might do it!!!!

Were did you hear there motors could only flow an X amount that u rated? And who knows what the stock cfm is truelly. The soup bowl, yes it is a sound device but it also blocks air
