What have you done to your powerstroke today?

Got this little fella in last week! :D Gonna put it on after the October races and before Diesel Thunder in November so I get some good before and after numbers with egt's and fuel only numbers. Excited for the results after seeing the flow numbers a while back.

Mostly want to see some cooler egt's but I feel it will probably make some improved fuel only numbers as well as allow me to use a little less of da juice.

Mainah!
New valves installed, reinstalled the head and torqued it. Need to do the manifolds and up pipes tomorrow. Injectors are en-route as of today so should have the engine patched up and back together next week hopefully.

Had a piston smack the valve, in lieu of bending the valve or rods, both rockers broke, as well as the lifter retainer snapped in half.

Hence my earlier post, lol

Got the rest of all the crap back on the motor yesterday, all torqued to spec. Waiting on injectors now which should be in the next couple days.

Build a new intake and installed a second Donaldson bfaf, one did not flow enough cfm. Much less smoke and faster spooling.

could have ust went to the 2790 filter. lot easier and less space taken up.. lol but with that said, i did that same thing long ago and it made a good difference. but went to the bigger 2790 size and it is still ok..

Interesting, I tried the 2790 alone and it was better than my 8.5" Donaldson. Then I tried both filters and there was even less smoke. So I made it permanent. In the end, I have enough intake CFMs and no dust in my intake.

I have used oiled gauze filters and every one dusted the engine.

did you try the donaldson or the wix/napa filter for the 2790 size? i only use donaldson so that alone made a difference for me.

and that last sentence is exactly why i refuse to run cone fitlers in anything. i ran every brand and style(dry/oiled) on my dually and they all dusted my intake. f that noise!

Donaldson ECB105006, the company I retired from has a construction division. Donaldson brand filters dominated in their equipment, they kept very detailed maintenance records on each piece of equipment.

My truck pulls our camper from NE Wisconsin twice a year out to the desert south west of Arizona and National Forest roads, it's life depends on good filtration. It has NO dust in the intake.

Donaldson ECB105006 Product Attributes:
Outlet Diameter:4.02 Inches (102 MM)
Body Diameter Maximum:10.51 Inches (267 MM)
Body Length:10.51 Inches (267 MM)
Efficiency:99.9 PERCENT
Efficiency Test Std:ISO 5011
Rated Flow LR:448 CFM (12.7 CMM)
Rated Flow MR:590 CFM (16.7 CMM)
Rated Flow HR:678 CFM (19.2 CMM)
Restriction LR:4.02 In H2O (102 MM H2O)
Restriction MR:5.98 In H2O (152 MM H2O)
Restriction HR:7.99 In H2O (203 MM H2O)

I stole this when I was doing some research filters.

All CFM numbers were between 16" H2O and 20" H2O (from what I read, this is the optimal range to determine the most true CFM flow for the calculated 631 CFM flow for the 7.3 Powerstroke).

From the Donaldson Air Cleaner Selection Guide: To find the correct CFM of a filter in a more simplistic calculation, you use the following formula:

Airflow (CFM) = HP (SAE) x SA
Where HP is listed at maximum value and a certain RPM, on the stock 7.3 Powerstroke, this = 275 HP
SA = (Specific Airflow) per HP. There are different values for 4-stroke, 2-stroke, natural aspirated vs turbo, etc. For the 7.3 Powerstroke, this number is 2.3

So, CFM = 275 HP X 2.3 SA, CFM = 632.5

This is a CFM airflow rate at the maximum HP your truck outputs. Replace the HP # to find out what CFM filter you would need.

The AIS is rated at 650 CFM. So, 650 = xHP X 2.3. 650/2.3 = 282.6 According to the Donaldson filter guide's equation, the AIS is good up to 282.6 HP.

*I did find other reputable companies that had calculations and they all were consistent with one another.
