I have the Severe Duty Ford intake on my 02 7.3, and i have the zoodad mod. Only once did my Filter get soaked but that was after several hundred miles non-stop in pouring down rain at 70-75mph. And I mean it weighed 10lbs or so and was dripping wet.Made my little light on the dash light up before I stopped.I have 2 3" holes in the core support,covered with stainless screen and then another screen behind the grille. That is the only time that has happened in 5 years or so. I was pulling some pretty good hills and I imagine there was a ton of air getting sucked thru the zoodad.
Getting ready to purchase a 07 6.0 and i doubt i will do the zoodad again,not sure it is really even needed on the 6.0 .

 

I have done the mod also and when the weather gets warmer I am going to try a test. I can monitor intake air temp. on my scan gauge and try blocking the hole and see if the temp changes.

 

Excessive rust in turbo has nothing to do with the intake side. It's been a common problem on these trucks and there's a TSB about it (you referenced it). It even occurs on brand new trucks that sit for extended periods on the dealers lot. I'd be more concerned about the Airaid (yes I run one--yes I HATE it) than the zoodad. If it wasn't for my current motor configuration I'd put the Airaid on Ebay just to make space in my basement. I've run the zoodad for almost 80K miles now with NO PROBLEMS. I don't even find bugs in there.

 

This thread is a little old, but I thought Id post to it as it seems the best place:


I have a 4 channel datalogging thermometer using K type thermocouple. Before using this tool for its intended purpose (monitoring temps of a lumber heat treat chamber), I thought Id run some sample data off of the 6oh. I put one thermocouple right out the front of the grill and one right in the intake of the stock filter inlet. I have a 05 with a zoodad type hole, mine pulls off the side right behind the side grill instead of directly in front of the inlet.

The datalogger is able to capture 12,000 data points and I used a capture rate of every 2 seconds. I monitored a couple of my drives home from work in LA freeway traffic varying from stop and go to 75mph with the zoodad open and a couple with it covered.

At hwy speeds there is no perceptible difference in temps with or without zoodad, both recorded a temp diff of ~.2*. At speeds less than 10mph the intake temp would start to rise noticably above ambient on both. While breifly stopped in traffic was the only diff between zoo or no zoo. No zoo would show a temp diff of ~20* where with the zoo it was ~15* diff. There was a slight lag to reduce temps on the no zoo as speeds started to pick up from a traffic slow or stop, roughly 15 to 20 seconds behind zoodad mod.

The testing was done at 80* ambient.

The testing is not completly scientific but it shows somthing, basically there is no difference at hwy speeds and a difference in stop and go traffic, but I dont know if a 5* temp diff in stop and go traffic and under the first part of acceleration makes a difference, maybe pulling the trailer out the 91 on Friday when stop and go can last up to 2 hours.

 

Great post and great info....

What brand of data logger did you use... I use to sell them for the food industry.

 

After studying this statement I have to ask a couple of questions for clarification. Did you cut the metal brace for the core support (the fiberglass piece that covers the front of the air filter inlet) to open a hole to the airfilter inlet in addition to the hole you cut for your zoodad or just the core support behind the side grill opening hole? My point being, I don't see where you're getting any "cold" air to the airfilter inlet except from where the factory originally designed it to come, which is underneath. I do, however, see a small design change I'm going to make to how my zoodad pulls air from the grill area by isolating the A/C condensor with a small baffle so I don't get any hot air "overrun" off of the condensor and everything is coming straight through the grille.

 

The datalogger is a Sper Scientific 800024, neat deal, I may hook up some thermocouples on the truck and use the datalogger on trips that I tow on. I could do EGT, trans, engine oil, and coolant.

As for the location, no metal cut, just the composit. It is just to the left side (facing forward) of the intake, it makes use of the "side" intake part of the grill.

 

The CFM air flow on the stock air box has more air flow than the stock 6.0L PSD can use. Even at max RPM.

I have never read any hard data that shows zoodad helping the air flow or any part of the 6.0L PSD.

 

I also did the zoodad mod through the side grill. But made a scoop behind the grill to channel the "cooler" air where it need to go(heated up a piece of plexi and formed the shape and painted it black). Recorded on average 10 to 15 degrees with mod
Outside temp 95 pulling 7k at 45mph. Taking the readings from the obdII

 

I am looking for information regarding 06 f250 and the use of performance products such as chips induction systems and 4inch exhaust. I pull a15000lb 5th wheel and do not want to hurt my truck. Thanks Jim

 

I am looking for information about 06 f 250 and the use of perfomance products and their affect on my truck Thanks Jim

 

I know this is an old post but wondering if anyone as info to back-up that the Zoodad works other than the one posted above.

Cheers!

 

I know this is an old post but wondering if anyone else has new info on whether this mod works or does not.

Cheers!

 

The Zoodad mod will work if you believe it will. On the other hand ,if you believe in science what you'll find is that ram-air concepts on a turbo-charged engine are problematic at best to model, but the turbo basically sucks in the air it needs, and any ram air effect will be lost in the noise. The shape and size of the air intake that is stock on my truck anyway, 2005 F250, is there for a couple of reasons. First is noise suppression - it is designed to reduce and control intake air noise. Second is air flow shaping and pressure control - the air comes in through a well-shaped intake, and flows into a large plenum. Bernoulli's principle comes into play here - the air flow is slowed and shaped by the venturi effect as it enters the plenum and is presented to the air filter media. The extra little 1" diameter hose causes the air to swirl and present to the entire filter media face more evenly. That all makes the air filter more efficient. If you worry about intake air temp, I have monitored the intake air temp on my truck both with an AFE cold air filter system and the stock system, and the stock system wins hands down. The stock system intake air temp tracks outside ambient very closely at anything over around 15 mph. It only heats up when sitting at a stop light. The AFE was a fair bit (I forget exactly) hotter at all times.
