There has been many dyno tests on just about every model of diesel truck made in the last 25-30 years comparing different air filters and cold air intakes. There isn't a single aftermarket system that performs better than a stock unit on a mostly stock engine.
hey wyd
I like my s&b cold air intake. I would imagine it does outperform the stock because of the filter surface area. But I could be wrong. However, if I had known at the time that Ford actually does make an upgraded cold air intake for the 7.3 and it’s bad ass, I would’ve preferred to purchase it. Not available at full force diesel anymore unfortunately but I’ll give you a part number check it out. Pretty bad ass and actually made by motor craft

I have this upgrade on my truck, but i wasn't looking more boost, I was looking for cleaner air. The OEM square box filters let to much dirt go by, this upgrade provides cleaner air. You could actually see a film of dirt in the 4" tube from the old OEM filter box, it's been clean ever since I did the upgrade. DIRT KILLS DIESELS!!!
This is 💯% spot on. Why kill your engine for 10hp or so. Those cleanable filters start clogging up within several hundred miles where I live. So they stop flowing more air fairly quickly.
you should think about making some ductwork to get cold air directly to that filter, the filter behind the battery sucks in all that hot air under the hood. I can tell a huge difference when its getting fresh air rather than hot air from under the hood.
Unplug your red line on the waist gate and you will get 20-25 psi. With it plugged in, your waste gate starts opening via vacuum around 5psi
You can also make your own boost leak test rig. Find a PVC cap and rubber boot to clamp on to the front of the turbo, drill and tap the cap and install a air pressure regulator. Hook up your shop air and put about 5-7psi (a little more if you trust that the cap and boot won't blow off the turbo.) Then spray some soapy water all over the entire intake system and watch for air bubbles.
You can see your IATs are around 124’ pre turbo! The biggest gain you are gonna see is, getting the intake filter out of the engine bay and into the fenderwell Less EGTs too
Im pretty sure u can’t make more boost because is regulated by the wastegauge actuator
Boost is a restriction in flow. The chip does nothing to change that. It just adds fuel to add horsepower. There is something wrong, it's not a Duramx :)
I would suggest checking your exhaust back pressure. Then getting Bellowed up pipes if you don’t have proper pressure (I think 35-45 psi). Also, I don’t know if I would trust the boost displayed on that gauge. It is getting readings off of the map sensor. Also important to perform a boost leak test. I just did a bunch of work to mine. Had lots of boost leaks.
OEM is best don't fall for the new filters that are crap.
Dude...do you want me to send you 4 quarters so you can go to the car wash and clean that engine bay?.....LOL
I think I would put the factory air filter back on it and make sure it's getting cold air. Plus you get that dirty air filter gauge
You have an issue. That truck should make 15psi or a little better on the stock tune. Around 20psi with the stock tune and the wastegate line plugged. Look for soot at the top of the uppipes where they bolt to the Y pipe behind the turbo and the manifolds at the back cylinders. Also worth checking the compressor wheel. It's pretty common for the stock air boxes to break a clip and unfiltered air chips or sandblasts the wheel. If that's all good, look for boost leaks.
Throw some hot shots secret Diesel Extreme in the fuel tank helps out the injectors and tons of other stuff.
You can also buy a 4" PVC cap in plumbing dept drill a hole thread in an air fitting put in intake at air inlet clamp down and find additional boost leaks.
10psi seems low, my 2000 250 is bone stock and sees 18-19psi. Curious to see what it is loaded
His turbo sounds terrible compared to mine too… I see 20+ with a straight pipe and wastegate delete
When did Fram become a factory filter? I thought Motorcraft is Ford factory filter.
Im diggin the 2 group 31s in the engine bay. Ive been wanting to grab a couple off 1100s of the shop floor and thow them in. Mine boosts to 21 with no tune. It hits 17 easily
Thanks for the AIT Sensor location. ive been a diesel tech for 32 years and still couldnt locate ait info online anywhere as to location and what it looks like. I bought mine with the air box already deleted so I never saw it original location.
Thanks again.
Don’t know about these trucks exactly but wouldn’t the waste gate control 10psi no matter what if that’s what spring is in it? Probably free’ed up some horsepower making it breath easier but it would still open the gate at 10 psi. Just a thought
I was thinking the same thing. Didnt know an air filter change would increase boost
Look at your EBPV to make sure it's working correctly, and also try adjusting the Waste Gate on the Turbo for more boost then you may see a better result. Also use a cool air box with the larger air filter like from RiffRaff for better results. It could also be your injectors need some HotShots Stiction Oil Treatment as well as some HotShots Diesel Extreme Fuel Treatment. Still an interesting video. Best Wishes and Blessings.

Check the up pipes on that 7.3. Almost all of them leak and you'll lose boost. There is an upgrade from multiple companies to fix them with new tubes and new Y pipe with flanges instead of the crappy oem seals.
I said the same thing.
It oughta make 17-20 bone stock, double check your map and back pressure sensors, if I’m not mistaken one got changed in an earlier video? I’ve seen differences in icp sensors between Ford models and international trucks even though they’re the same engine….wonder if you have the wrong sensor in it. Put a mechanical gauge on it to confirm the edge is correct
Putting on this crap air filter is Great until it gets wet and plugs up the paper and starts sucking oil into your motor from your CCV. The new air filter might sound better but it's crap for your motor. Also I noticed you don't have your little plastic cover by your fuel filter, the little cover is there so your fuel filter won't jell up in the winter because the little fuel heater in the bottom of the filter can can't keep up with the cold, put that cover back on. also the stock air filter can protects the stock air filter from rain and has been proven to supply more air to your motor than what you did with that after market filter. I have to laugh how many people fall for the after market filters and Mods that actually hurt your performance of your motor. and make it ware out faster. Want a hot rod? buy a hot rod want a truck that is a pulling machine? keep the motor stock.
There are several mods that improve on the design and create a much easier to diagnose and repair engine. Efuel, deleted pedestal, improved HPOP lines, are a few. Stock does not mean best. How many stock 6.dohs are left running today?
Also the exhaust back pressure warm up valve probably needs cleaned out. That truck should make arleast 15psi, maybe 18-20 with the TS chip on level 6 and the waste gate actuator vacuum line disconnected. Factory boost/fuel cut programmed in the ecm is at 18-20. You can use a cheap air pressure regulator as a "Boost Fooler" pre-set at 16-17psi on the boost line going to the MAP sensor mounted near the passenger side fire wall. This will keep the ecm from seeing enough boost to cause a fuel cut. Although factory fuel injection system and turbo on a 7.3 will only make a max of about 22-25 on a good day.
John, the truck has issues. It should be making way more than 10 psi with the TS chip, it should be up around 15-20 depending on load. Did you confirm the chip is installed correctly? Those chips are notorious for not making good contact with the ECM
You might want to get something to keep the hot air from getting suck in.
This is a better filter for engine longevity though. Why kill your engine for 10 more hp gain ?
You might want to make sure there’s no broken exhaust bolts/exhaust leak.
Agreed. Also the up pipes are bad about blowing out. Either way ur loosing alot of power. But typically its up pipes on a 7.3, they have a better updated kit out now besides factory. Also Iman aftermarket downpipe will also make a very good gain. But personally I would tow with that 75hp tune in it. It will make alot more power with a load behind it. And the exhaust leaks fixed. Also should make morethan that, especially with the tuner jack up 100hp, thatd be 200 more torque. Love the channel
Hot air intake, only true test is to have factory battery/air box for factory cold air intake vs new setup. Pulling a trailer @ full temp.
consider installing a Wicked Wheel in the turbo for faster boost ramp.
My 2002 made 20+psi stock. Could be the edge gauge.
These hot air intakes reduce the air density going into the engine because they draw air from under the hood that comes thru the radiator. The stock air box draws cooler air from in front of the core support providing more air density. Whether that makes a measurable power difference is not shown by this test. Louder intake is less desirable to me.
Smoke is probably from dirty fuel filter, based on how the rest of engine looks. Something I did that worked wonders with regards to turbo performance that's a piece of cake to do...tighten up the hose brackets that come out of the Y pipe/turbo. You can use either a wrench or deep impact sockets, they are all the same size except for one that's towards the front of turbo that's a little bigger. Don't forget the hose brackets that go down on both sides of the radiator! Might need a stubby wrench to tighten those ones. Takes 10 minutes to do all of them and my turbo sounds WAY better. Plus gave me a little more pep!
You can also use a flathead screwdriver to tighten up the air filter related hose brackets while you are at it, you'd be shocked at how loose some of them are..
So tightening some stuff can make a turbo louder???
@wheat Superduty yeah!! Cause if your boots are loose air is seeping through which not only causes loss of boost, the turbo whine/whistle is replaced by the sound of leaking air, the volume of which depending on how bad your leak is!
@@jamesb1988 is there a video on what to tighten????
Just purchased the FA1757 Air Filter. It's a $150.00 with a one year warranty. OE part. My research suggest the FA1757 is superior. Thoughts?
Factory turbo only pulls 10 psi. You need to change that part on turbo that vacuum line is hooked up to . They sell some thatvallows waste gate to open later which will give higher boost
Im pretty sure its for the egts because its a cold air intake , use do a. Video of the egt difference
Have you blocked off the wastegate? Most are limited to 10 pounds so either mod will be limited to the wastegate or you have boost leaks
I have not blocked the wastegate
I have a 2001 f-250 with the 7.3 I have the edge as well I Set it on race mode and I get 22 pounds of boost with the same filter that you have I don’t know what you have yours programmed to but on Tow mode I get 11 pounds of boost
Not sure how the pcm is reading boost on a 7.3 . If it's calculating off the backpressure sensor. Maybe the little metal tube has a hole in it , giving low reading.
Isn't boost controlled by the wastegate on the turbo.
will make more boost with the trailer loaded &
connected with a load on it. My 2001 F-550 makes 29 psi pulling a 34 foot race car 5th wheel trailer
The up pipes may be cracked or turboen exhuast housing could be charged the home isn't normal my opinion only
I'll bet it was a problem with your up-pipe's leaking, possibly other boot leaks too. I could get 25# with my stock turbo no problem, after fixing mine.
Pull the line on the waste gate and send it lol
AGREED! Should make 20-25 psi
its all about surface area the stock filter has x amount of inches and the conical has x amount which ever has more will ultimately flow more. so if you cut the conical and roll it out is it the same surface area or is it less. looks like less to me maybe its more hard to tell. youre also missing part of you airbox that covers the battery and takes in air at the rad support in front of the battery
You would need a turbo upgrade kit to increase psi
There should be a Donaldson air filter upgrade for that truck, long life and best insurance for the engine. None of the "hot air intakes" are worth it. And route cold air to it, seal up the box, whatever it takes.
Turbo John you still have your 7.3 if so drop some more videos please
Upgrade to a 02 OEM air filter box.
Dude if you are only making 10psi something is wrong. Even with a broken exhaust back pressure tube leaving a 1/4 inch open hole in the manifold and the sensor not reading at all my bone stock truck would make 13psi. Once that was fixed it was more like 15-16 (around what the trucks should make stock) and that’s at 1500ft in elevation with 240,000 miles. Tuned you should be making a lot more especially on a 75hp tune.
It's how fast the motor raps up now... Do a 0- 60mph and 20-60mph timed test bet it's a little faster
i hear an exhaust leak
Doesn't the waste-gate actuator limit the amount of boost?
That's the thing the boost on the 7.3 is limited. I know I have an 01 7.3
Difference in min I used the Donald b085011, it accelerates much quicker. Was nigh n day.
Your turbo sounds wore out I could be wrong but it hums more than whistle
You are right, the compressor wheel was very beat up. I changed the compress wheel
It sounds like the up pipe to the turbo is leaking
Air to air busted?
Couplers tight? Not leaking?
Sounds like a bad charger and also a slight boost leak probably from the up pipes. Common problem
Put a T in the line and make all the boost
That tuner is causing the smoke
Put your trailer behind it need more load maybe ?
Stock waste gate is 11psi on those. That’s why it’s staying there.
I pulled the line, it makes about 14 with it off. Also noticed the edge monitor is 3 psi low from the scan tool.
Hey John
How to make the 7.3 diesel engine sound better?
I mean is there anyway to have it like a rumbling sound?
8" tip!!!
Wash that engine bay cuz all that dirt n dust is holding a bunch of heat in there. A clean engine is a happy engine! Just throw the stock airbox back on with a k and n filter is ur best bet. I wouldnt think changing a filter would give you anymore boost. Now switching from the 75hp to the 100hp tune and not seeing an increase is a different story. Time to hit the internet forums to see what the diesel guys are saying could cause this issue
Got a boost fooler on the truck?
he's going to get that futher down the road
@@kevin_nagle I'm not 100% sure but I think without one the boost will be limited. But my truck before that still made 20lbs. So he may have another issue
So this mod isnt even worth it?
My guess is your up pipes are leaking at the turbo and or your exhaust manifolds are leaking .
I put a 4” down pipe to 5” exhaust on my 03 7.3 , then added a S@B air intake . Made a lot of differance but when I towed I’d get turbo surge . Ended up with a bd thruster 2 turbo , bellowed up pipes , boost fooler , cts2 monitor , Hydra tuner with 1023 diesel tunes , did the pedestal delete in the turbo and bigger housing . My 7.3 rips now compared to what it was . Still don’t hold a candle to these 100,000 new diesels . I’m also running 38s and it sets you back in the seat pretty good . Next is injectors and fuel upgrade and I’m done .
John put the Ford filter back on they do years of testing & give u the best ! That filter will not filter as well & your motor will suck in more crapp !!!
Incorrect. The stock air box is trash. It's common for the clips to fail and the engine breaths unfiltered air. A lot of 7.3 engines and turbos have been replaced as a result of that junk stock air box.
I cannot hear my turbo like that
Check fuel filter
You have something going on there, do some digging and you'll figure it out!
4:52 ... a little bit what? 😆
Futher!!
Waste gate needs mods.
Also check the motor on data stream on a good scanner thinking a sensor is acting up and not setting a sel
Completely stock your engine needs 12 to 15lbs of boost and apparently your not gettin that so you might want to do some diagnostics and see where your problem is.
SHOULD NOT SMOKE AFTER A SECOND. YOU HAVE AN ISSUE SOMEWHERE. SHOULD PULL REAL HARD EMPTY
Maybe the problem is it's a Ford. LOL
who cares???
