BHAF and cold weather
HEY FOLKS!! Well it is April 6th and we got 20 degree windchills here in the Delaware Valley. Wife and I went to birthing classes tonight and we took the truck. BOY I will tell yah,she was singing tonight (the truck ). I could actually hear my turbo spinning at the redlights. This real faint whistle. As I was traveling about 55mph ,the engine was really humming. Like never before. Is this normal with the BHAF and colder temperatures?? OHH by the way, the engine did warm up to its fullest and it still made this "drone" if that is what you want to call it. Actually it sounded like it was in D 2.
Is it a S O P with BHAF's??

You won't notice any power increase from the BHAF. Mine was loud all the time and I loved it. Cold or hot. My truck always drone's, but I guess when you have 4" straight pipe dumped at the rear axle it will do that.

I installed a Turbo Air Guide about 6 weeks ago. It cut probably 95% of the noise associated with the BHAF. That wasn't the primary reason I bought it, but the quiet will be nice out on the Interstate when towing 10-12 hours at a stretch.

Basically, a honeycomb flow straightener. It takes the turbulent airflow coming out of the 180* bend in the inlet piping between the BHAF and turbo inlet and straightens the flow so that it is laminar in nature as it enters the turbo compressor impeller.
This design is commonly used in process piping, wind tunnels, aircraft jet engine intake inlets, etc. It's based on the decades-old standard practice on industrial engines such as our company manufactures that a minimum of 5 diameters of straight pipe is required at the turbocharger inlet. In other words, if the turbo inlet is 20" pipe, 100" (8'4") of straight pipe are required leading into the turbo to ensure non-turbulent airflow. When this isn't possible, the honeycomb flow straightener provides the same effect as long as the thickness of the honeycomb is more than 5 times greater than the effective diameter of each cell - the honeycomb flow straightener acts like a bundle of individual straight pipes whose length is 5 times or more greater than their diameter.
