Soupbowl... Mmmmm...
 

I did the soupbowl to my 92 the other day... Really didnt notice much of a power gain, or an EGT drop.. Anyone dyno with this mod? By the way, never really paid attention to it, but when I was cutting on the air filter lid, I noticed a threaded valve thing on the top of the lid.. Any idea what that is for? :humm:

the threaded port is for ford testing for engine tests. they tap into that, fuel pressure and a bunch of other ports.

as for the soup bowl, nobody really has tested it yet, but it really cant hurt it by taking it off. i always cut mine out as soon as i get the trucks.

this is what gets hooked to it.

Thanks. :tu:

wtf is a soupbowl and why isnt it in you cupboard? :D

On the 6.9 and early 7.3s without turbos, on the lid of the air cleaner was a bowl shaped piece that was supposed to help direct the air(at least that's what i was told). Supposedly cutting it off increases the airflow. I didn't notice any difference when I cut mine off either :nope:

was also told it waqs a muffler ever run the engine without the air cleaner on it?. lol

Not yet but I'm sure I will at some point. My trucks loud enough, I can't even hardly hear my radio over it. Doesn't help that I lost the insulation under the shifter boot. :argh:

Thats because its a noise reducing device only. It doesn't have any affect on airflow.
