Any change with the 'soup bowl' removed?
Been debating to remove mine. Sorry, no feedback regarding cold air intake except I have heard from local sources, one needs to take caution due to diesel engines needing very clean air filtration.

i have noticed somewhat of a change. it don't seem to lug so much but nothing drastic. i also have a 99' f250 that has cold air it is a big diffrence it also seems to not smoke as much i think because of better air flow but dont quote me im not a mechanic i just enjoy tinkering

The 99 is electronically controlled as far as how much fuel and the timing as well as turbocharged, which means much more air in the cylinders.
The 83 is all mechanical for fuel and timing control and naturally aspirated.

The computer control and the turbo is why you see less smoke and more power but the downside is there are more things to break.

Everyone here that has a cold air intake has made their own.

Unhappy

do you see that much of an increase with the cold air on the6.9 na its an everyday driver for me but sometimes it feels like i gotta do something for power or get run over if i hold it to the floor it will eventually get there but then you gotta hold it there aint no sweet spot for cruisin down the highway

I removed the drivers side radiator support completely and then made a new one that is mounted from the top of the support.

im not to knoledgable bout this but wouldent a hood scoop inducted cold air intake work better and have something similar to the bottom half of the "soup bowl" with a
thick seal that would make a tight seal with the hood scoop every time the hood is shut. and if it was done right it would look nice inside and out

i would be a little scared of water coming in from a hood scoop because there ain't much way to drain it before it gets to intake. trust me, water in a diesel intake don't work well. better to duct it from low area where air can flow uphill to intake but not the water. just a thought.

hey ur prolly right that might not work so well and i had a half a mind to try it... anyone kno how a pyrometer works and gets hooked up or are they just a waste of time? cause all i kno is they are a thurmol couple and moniters the millivolts of the glowplug i think RIGHT?

i think a pyrometer monitors exhaust gas temps, but since i don't have one on my truck i'm not sure. if you're running a turbo they pretty important cause if you run too hot, many things can happen, most of them bad.

Thermocouple goes in the exhaust manifold, the pistons are what you are protecting with a pyrometer.
You want to measure the exhaust gas temp as it exits the cylinder.

Piston damage can start at 1250 degrees.

Cranking up the air pressure and the fuel delivery will make 1250 an easy number to reach.

dave,
im still learnin bout all this and do you kno what the average temp a 7.3L navistar runs with a aft. turbo? would it need a intercooler? and how would you boost your air and fuel? what does a pyrometer run at a stock average?
