I currently am working with a manufacturer to have an additional BHAF filter option. This filter uses Donaldson's Powercore technology and has a capable flow rate of 1300 CFM while filtering the air down to a micron rating substantially better than stock.
I am currently in process doing heat soak and IAT temp checks and EGT checks at WOT runs, cruising, part throttle acceleration and transient boost speed from cruising to passing acceleration.
Next tank of diesel will be a fuel economy test to see if any improvement exists.

I will do my best to keep everyone up to speed.

This is not available to me that is for sure. I also can not like any post.

 

This is both on my phone and laptop.

I missed it even...

 

The problem we are all missing is not a donated member. The option is disabled.

 

Thing is it was a BoD group decision when the site rules and options where made back in Feb.

Well craptastic   ....unfortunately as much as I would like to donate, my pocket book only coughs up dust.

Let's head honcho guys meet in the mod section.

Picture 1 is 1.5 hours of idle time only.

Picture 2 is 1.5 hours of idle time plus 400 yards of driving  (200 yards 3 min of idle and then an additional 200 yards)

Picture 3 was a heat soaked WOT run after driving in traffic for 20 min. A second EGT probe on the rear 3 cylinders shows approximately 50 degrees greater temperature.

So far all of this is equal to the factory air box with the exception of a few things such as IAT temperature on picture 2. This is the only elevated peak. As I mentioned earlier this temp then suddenly dropped down to 143 degrees so the BHAF is not retaining heat.

Thanks you me78569.

It seems the 2nd and 3rd photos have flipped around but the data is obviously there.

As you all can see all testing looks promising so far.

I will keep everyone up to date as I see results.

Better?  I tried to flip the 2nd and 3rd.

Yes, much better thank you very much.

So gents another quick update.

From driving a particular route in similar conditions last week (light rain, temperature in the mid 80's and humidity up near 80%) my cruising temp at 60 MPH was floating around 600-650. Using the new BHAF I have seen a slight drop in cruising EGT of roughly 25 degrees. I was again driving 60 MPH and the EGT's were I'm the 575-625 range. The biggest overall difference is in transient turbo boost speed when passing. So the trucks overall responsiveness has been better than using the factory airbox. Then again these are only marginal differences but it seems to be an overall improvement. A MPG test may commence tomorrow with a 40 mile loop.

With rolling hills and some flats here in Idaho I typically see 550-600*F at 55 MPH and about 1.5 to 3 PSI of boost. Today temperature max'ed out at 79*F and about 25% humidity.

I see 575 to 625 now at 60 MPH, under the conditions I mentioned earlier. This is an improvement over the stock airbox. I'm sure the 1300 CFM of flow capability is helping. I normally see 0-1 PSI of boost at 60 MPH. Also the intake(air horn) temp is lower between 5 and 10 degrees.

If I had the time and money I would like to install another temp probe it the hot pipe (prior to the intercooler) to really see the difference in air temp the turbo produces.

According to a Borg Warner software to size turbos the temperature of compressed air as it exits the turbo will be near 415 degrees while pushing 35 PSI of boost. If this is accurate the BD aftercooler is doing a great job knocking that down to 100 degrees within the intake manifold at 90 degrees ambient air temp.

Also before the new BHAF that temperature would be up 10 degrees under the same conditions which is leading me to believe the turbo is operating more efficiently.

So gents last night I made a little video of the BHAF.  

 

 

Yes, the results are that good. Now if I can work with the vendor to build a box to house this (mostly for sound and also moisture ingestion) we will be in great shape. I hope to speak with the guys tomorrow and give all of you a heads up of what we can expect tomorrow.

You have to tell how you are turning so low an rpm at 70 mph. How much bigger are you tires than mine? I have the same gears on 265 75r 16's and turn 2k at 70 mph.

All rolling around on 285/70R17's.

 

Borg Warner 62/68/.80

 

Between turbo differences and tires the numbers are going to be different for most here. Lot of stock turbos around here.

I do believe I mentioned it on the video but maybe I did not. 70 MPH is actually 65 MPH.

I have yet to head to the dealership to fix it but it's great for those who like driving 5 MPH over the posted limit all the time. Prevents speeding haha.

A factory HX35W and HY35W both have the sane air flow I do believe was around 60 Lb/min. Which is still more air than the current BHAF filters are rated for.

I've been running many different drivability testing. Throttle response has increased compared to the factory air box as has the turbo sound in the cab. Most will not have an issue with the sound even without the silencer ring due to the Holset inducer blades being rather calm in pitch and the compressor inlet geometry helping with sound. If you do run a Borg Warner turbo in the S300 category they have an attenuator compressor housing to help reduce sound which also helps with airflow by a small percentage.
