Would you be interested in a new air box if shipping didn't double the price?

[TuffMudder]

I ran into some initial problems with a new airbox for my HDJ81's 1hdt, but I'm going to stick with it until i get it sorted out. I'm currently having it done in mild steel, but i have a friend who does stainless welding. There have been a lot of talk about these airboxes that have a plate filter sandwiched between an upper and lower air box and the fact that half the cost of the ones available is from shipping to the US

I'm trying to figure out if there is enough current interest to try to get a group by of these once I get the kinks work out. To be clear, i would just be facilitating this, the work would be done by a full time welder whose been tig welding stainless for the last 15 years.

So, is there any interest?

 

[TuffMudder]

I'm shooting for the box to be optional 4" or 3" inlet and outlet, stainless steel. Nut welded below the lower phalange with hex head bolts to secure it.

My plan is for it to be built around a filter sized for the chevy duramax 6.6L which should be easy to find. Filter dimensions are:
Height 1.625 in (41 mm)
Outside Length 12.5 in (318 mm)
Outside Width 9.875 in (251 mm)

Would this be an acceptable filter choice or is there another plate filter dimension with wider acceptance?

I fitted one to an 80-series with a v8 swap. Very nice product but depending on how much HP you are running they can get large as they spec size by horsepower.

Cheers

totally wish i could buy a box to fit my application right now. problem is i need it sooner that later. i’ve already waiting over a year for torfab to have his ready but just can’t wait. that’s why i’m building my own. my problem is my 1hdt is in a 60 series so even one build for an 80 series will likely need modification to fit anyway. having one to drop in and go wouldnbe sweet though. good luck!

No, it's low on the list of value for money, bang for buck modifications for most vehicles.

Exhaust, tuning, intercooler, turbo upgrade,

then airbox depending on how far you go with turbo upgrade and how much power you are chasing.

By the time I'm flowing enough air and making enough power that my airbox is a restriction, I expect I'll need to upgrade the transmission to hold the power, lol. It's way down the list for me, behind intercooler.

Hopefully by then Torfab has a bolt on, off the shelf solution available.

Did this go anywhere?

Did this go anywhere?

Probably not since a stock Duramax box will fit in place of an 80 box with slight modification.

wow, thats news. will search.

I think one of these UZJ/VDJ200 series would fit in easy enough with some work.

Here is a setup i just finished, using chevy air box on a 70 series w/1HDFT. Was fairly straightforward, required some shaving of the bottom of the box to get it to sit down far enough, otherwise physically its a pretty good fit.

I have exactly the same setup and because the inlet is 6” and outlet is 4” if breathes great

That looks great! Any details on how it connects to the fender intake, and the bracket you made up? What year duramax is this filter housing from, or are they all the same?

 

[Loober]

Ive found the box is the same for gas and diesel, basically any 2000-2004 v8 chevy uses the same box, I found mine on ebay for $80. Depending on type of truck you are installing this in, you'll have to play around with fitment. and build a bracket for it to match, its def a custom job, will require some welding, trimming and fiberglass. As for connection to the fender, the box comes with about 3.5x6 opening in the back, my 70 already had a similar size opening in the fender at the perfect location, so I got it as close as possible and used foam weatherstripping to make a tight seal. As for custom boxes ago, this one is about as close to being perfect without building one from complete scratch.

I am also running a snorkel so I built a tunnel through the fender into the snorkel.

I was eyeballing my buddies air box in his 6.0 LS Chevy. Glad to know it could fit in a 70. Hopefully it fits with the Cummins.
