Diesel truck discussion

Its not about air temperature.
Its about air density.
If you're bringing in warmer air, this makes the intercooler less efficient.

 

Wait!
A 'Black Widow" is ...red?!?





Dang! Thats a sweet looking rig, Woodsnwoods !!!
I sure hope it works out for you!

 

I wont bother with arguing... the numbers are proven.

Gale Banks is a numbers fanatic and he's proven the air density advantage time and time again.
He calls the Filter-On-A-Stick, "jackassory." (His words not mine...I think they look cool, personally)
And a good way to lose 100 horsepower in this example.

Almost too nice for wood duty! Boy that is NICE!

 

Doh... well I guess a fabricated housing is in my future! Thanks for the info!!

 

Stock to big open filter on my 7.3 was lower EGT by 50-100 on cruising speeds. Wide open was pegged past 1500 so I don’t know where it would have landed. That was with a DP tuner 5 position. It didn’t care for the highest tune as it would run out of HPOP pressure around 3500 rpm.

 

I may agree that on the old trucks that a bigger (free'r flowing) filter may be better with modifications, but as a general rule, the filters in the newer trucks flow a lot more air...


.....................................................
I remember many years ago reading magazine ads that were proclaiming "up to" xxx horsepower by adding a filter system (Or exhaust). So many added a filter and said it gave them more power...when in all actuality it may have only gave them a couple/few hp or no extra power because other power adder mods were where the potential "up to" power was calculated.

One of the popular mods for my '01 was drilling a big hole in the air box to let the turbo sound out... lol

 

I haven’t touched the 17 Ford or 19 Cummins air box. One has a more open exhaust and the other is none stock for now. The 19 Cummins is getting 22-23 mpg on the highway without the 5th wheel and 9-10 with it. The 17 gets 17-19 empty and 10-13 loaded with the help of the exhaust and tuner.

 

​

Kinda like back in the day when everybody and their brother made "high performance" exhaust for bikes/quads...MANY of them gave little to no power gains once they were actually tested on dyno...but people still seem to feel that louder is faster/more power
I seen a really sweet Chevelle the other day that was obviously NOT stock...had full mufflers on it (quiet) but you could still tell this thing was freakin bad to the bone/big time horsies under the hood! Made me want to do the Tim Allen grunt...

 

Ooh clock springs!

Not fun. I had to do one on my mom's 99 grand Cherokee.

 

Umm yeah. Huge numbers

 

This theory applies to ported saws also .

 

Ooooh! D&D pipes on sportbikes. Loud AF, but usually less power than the factory system.

 

It was Kerker 4 into 1 pipes here.

 

Those actually made a lot more power on the late 70's to mud 80's bikes. Had a 4-1 full kerker exhaust on my 78 kz1000. That thing was very fast for it's day. Later in the 90's, kerkers sucked.

 

Its a sound I'll never forget!

 

Those sounded good, at least mine did. Now those D&D pipes, even slip on/ bolt on muffler only sound just plain awful. Like there's no muffler at all.

 

Much from the guilt of Turbodiesel, I added a heat shield. Not perfect, but I used an IR temp gun and was suprised by the results. Boy it DOES work...Also did a few holes for the zoodad mod. After watching the video, I figure colder is better and I’m in CA, not much rain or snow to worry about.
