Does the BHAF flow more than the K&N cone filter?

I'm considering the air temperature under the hood. In cool weather, my BHAF is ok but it's HOT out there now and the Scotty with the big cowl inlet would get cooler outside air to the turbo which means more hp.
Does the Scotty flow as much air as a BHAF?

I checked air temp with a digital meter in the cab and the lead hooked right on the bhaf. It was in the high 80's or low 90's when I checked. In VERY heavy stoplight traffic the under hood temp of the filter was as high as 100-103 I think is the highest I saw one day. As soon as I started, fan would blow and you could just about watch the numbers starting to drop. I got on the highway and started to go and it dropped down to like 78-80 degrees. I don't do much city driving so that temp for as little as I care to be in the city is no big deal.

What kind of ambient temps? I have the Juice, which reads intake temp in the manifold and have seen 135* on 100* ambient temps. In cooler weather I am under or around 100* intake temp.

Here is my BHAF and custom air box I made.
A new filter that has just hit the market is the Amsoil 4090. These are nanofiber synthetic filters that do not use oil, can be blown out and reused, and flow more than a BHAF and a little less than a bad filtering oiled filter. I would have one if they come out with a red color line.

Kroner, I like the BHAF lots better than my K&N...turbo inlet wheel is cleaner too.

SSweeney, Need one? nope, but if you want a greater airflow capacity and turbo sounds, the BHAF lets sound out as good as it lets air in.

Nice box RJF, right color too.

On 100 degree days the turbo compressor really heats up the air...I can't hardly touch mine after getting home and motor idling. The aftercooler cools it back down near ambient before it goes to the engine intake.
Dodgeguy's temperature research indicates there's alot of air under the hood and some doesn't go through the radiator.
Another benefit of a cowl air source is a possible air pressure improvement to the turbo inlet at highway speeds. There was a seat of the pants power improvment at a 70 mph punch between the scoops on my long gone '70 W-30 open vs stuffed with towels.

TRCM

Well, I have put a BHAF on the flow bench, and it flowed more air than the bench could measure...I'm curious as to what these other brands really do flow.

Clunk

Do you mean the water column(red) wouldn't even come up to 1"?
If you get any inches of water, you can do a conversion as described in the Superflow black book.

Marine

Just to set the story on the Marine version BHAF straight:

It is the same as the BHAF, except that it has a wire mesh internal. This is in case the filters do get wet, the suction will not pull the wet media into the turbo. It is unnecessary for our trucks.
If you search back to my posts in01/02, you will see the specs on the research I did.
