Wow! Thanks General. Talking to one of my engineer friends… he’s is saying that the 1.85 VE used in the Donaldson calc equates to about 12.5 psi of boost.. probably 18 with losses. 33 PSI of boost would affect that VE number and probably needs to be accounted for. I’ll go back to...

Coming back for completeness. Been communicating with Donaldson. Turns out.. page 12 of the 371 page Filter catalog has the calculations. I provided input. 7.2 liter turbo charged Cat C7 2400 max RPM. The customer provided the following information: Displacement = 7.2L RPM under load = 2400...

Always learn something during mock up. Need clearance for the housing clips. I've seen some examples of trucks with dual intakes on the same side.. But been confused on how they service the filters stacked so close. These required 14"+ inches to easily remove the lower intake lid and...

I'm not affixing to the cab... mine will be attached to the forward most cross member. Bracket is mostly made.. just need to test fit the boxes again and make finished the bottom mounting.

Weird. Magnet wouldn’t stick to mine.

@GCecchetto Can you link/comment more about this? Thanks.

dumb question. The stock intake tube. Is that aluminum or stainless?

I ended up with two D100390 filters. for my C7. I plan on bumping the HP and using my vehicle in altitude and desert (AZ, NM, UT, Mexico) I plan on putting them both behind the passenger. Trying to sort out the why pipe connections now. The output is 6"... I plan on using a 6"->5" 90 on...

My mistake when purchasing...Your gain. I'm putting pieces together for my A/C in the LMTV and bought this condenser., forgetting I'm putting a pass thru and don't want it on the roof. $350+ shipping. Send me your zip code (yes.. It will ship. I had it shipped from California).

Option 4? Remove pintle and make a replacement with 2” receiver Since I’m converting this truck to a camper. I keep trying to think of a situation where I’d use the pintle.

hi folks. I read this thread, but it diverged into image file size. https://www.steelsoldiers.com/threads/lmtv-hitch-extension-kit-installed.194937/ Has anyone solved the 2” receiver hitch onto the extendable hitch problem? @Third From Texas did you come up with a suitable solution? I had the...

The wripling on the panels in this picture is my concern. Not sure whats going on here, but the seams look like they are separating... I like the idea of composite for the clean panels, but don't want the added 'torsion' frame. for many of the reasons stated in this thread. height, torsion...

Want 4x more zen?

That’s a wrap. Speedometer set. CTIS over speed value set (which included a fun side project) Ride quality is beyond impressive. And super quiet. Now I need to find a place for this crate.

thats what i meant :). my head was still mush from all the wires and junction numbers

Case closed. Working just as designed again. Opted for the non cut way. Incase I want to add the switch later. Made a minor tweak to the pressures. My PCU is the j1708 communication model.

@Ronmar Amazing!!! fresh brain... went out this morning.. pulled the dash open and found j913. it was as you suspected... no jumper at all. my only guess is that it bounced its way out and is somewhere behind the dash? I toned everything, leg by leg back to and through the cb40, back to the...

made a bit more progress. tried chasing j111-e towards CB40... didn't make it. after i cleared a bunch of room in the bundle. I was able to find j111-e traverses the cab bundle. looks like CB40 also traverses the cab. next stop.. open the dash and see whats behind door#2. k52? i couldn't...

I'm sure it's somewhere in the schematics... but got through another troubleshooting step. one of the steps says to check resistance on j112-b and j112-d resistance was not in range (30-80 ohms). The reason I checked here is... I've seen the lights come on on the unit twice. once after i...

Thanks @Ronmar I'm learning.. I don't have a CTIS switch... and can't seem to find a diagram that doesn't have one. So trying to figure out how P111-E gets to CB40.
