Truckers, lets see your rigs!

From what I know (very little), people seem to like them better with the vgt gone but that’s just a little hear say.

It just depends how much you use your jakes and what model it is. CM870, 871, or 2250/2350?

Well found some bad news on dads isx. Injector cam bearing was the cause for low oil pressure. So looks like it will be getting an inframe.

It will be deleted at the same time. Should the factory turbo be left or is there a better suited turbo? Do the vgt operate the same afterwards?

Leave the factory turbo but get someone to tune it that knows what they're doing. Anyone but PDI.

Injector cam rules out 22/2350.

My deal with hardwood is the changes in temp. Mine drew moisture something horrible. It’s not got anything to do with keeping clean on my end, I mean I have a painted aluminum floor now so that’s even worse. This truck used to have hardwood, we now have aluminum, and the 359 used to have hardwood and we went back with carpet.

Depending what a guy wants to spend there are hardwoods that are moisture resistant. But we are talking 10-15 bucks a square foot. Possibly more

Very good point. :Cheer:

I wanna say 871 but I can call kw with last 6 an they should tell me. The truck is at a mechanic who does diesel spec tuning I believe.

Some guy also gave dad what looks to be the vgt control valve with a bolt threaded into it to change starting of veins?

The jakes are weak dad said and we both like to use them.

If anyone is familiar with diesel spec maybe a suggested hp tune with the delete or let it remain stock power just deleted? His acert is pdi tuned 650/2150 I think and he likes it but he drives it.

What model/ year isx and what's your power goal?

Guess this happen just a little South of me today.

2007 kw so guessing an 06 engine? Cm870 565hp

Wanting better jake brake performance. As for hp the truck has enough power but if it runs better at a different setting then would make sense to go up some.

That's an actuator for an 870. That someone has modified for som e reason. Can you tell a difference from stage 2 and 3 on the jake? I'm almost willing to bet it has some kind of tune and the vgt is inoperable now. I've yet to see any good diesel spec isx tuning, PDI not any better. You can get good power out of one with the stock turbo, and keep the third jake stage. You'll lose that going to a standard turbo. But, better fixed vane turbo will support more power. Sounds like you got some other issues goin on though. Where are you located?

The motor an tune is stock to my knowledge. The actuator is from a guy who had it on his isx and gave it to my dad to install on his once it’s deleted. His instructions were “use the bolt to adjust once it’s installed” lol Not sure where the other guy that idea. I can’t answer for a difference in stage 2 or 3 of the jakes I’ll ask the old man. The truck is getting torn down at the moment for the inframe.

So would weak jakes be an indicator of the vgt not operating properly? I imagine there is a test for this? I don’t think he’s to worried about more power as he likes the power the truck has now. But says the jakes were almost nonexistent but he is used to his acert which has great jakes.

If rocker shafts are wore, repace em with a jake tuneup kit. A coupe new solenoids are usually a good idea. I'd definitely say something s wrong. Cummins with the vgt jake is really good so long as its in workin order. I'd pull the exhaust housing off the turbo to check the condition. if its all good I'd probly just do egr delete for the health of the engine. But not diesel spec. Pm at some point. I know a few guys north of the border that can get you squared away if you wanna go that route

 

[zfaylor]

Leave the factory turbo on the 870. They aren't a very expensive unit to justify removing it and losing jake power. There are a few different sized units on those. They can all support decent power.

A couple local shops here use diesel spec and people seem to like it but for the money there are certainly better options. That being said, at least their tuning is fairly safe. Cannot say that for some of the other options out there.

Yes it’s $2500 cad for tune and delete. And delete is just the puck in the cooler.

I thought all ISX:s had electric actuated VGT, those pneumatic versions are not expensive anymore.

Largest factory wheels for VGT Holsets are 74 mm compressor and 80 mm turbine, with 40 exhaust housing they can make quite a lot of hp. HE series wheels are very efficient.

Have read that a mm2 tune would be good for the truck.... can’t seem to find out where to get or what not.

Ashland KY to Davenport FL, 1001mi 4.63mpg 75mph @ 76,000 up Jellico Mt passing everything in sight with the exhaust as cool as the other side of the pillow.

But remember kids “single turbos are better”. I lost count at all the 1000hp Volvo’s and Scanias that passed me in the hills.

84k+ 4.16 mpg right on my bumper. Almost started a fire when he threw the old pages out of his elog in the trash can. Things can be dangerous.

Hoping by next year we can all finally afford to ride in style in a European cabover with a 100” wheelbase with V8 powa!

Bet on the way back we got 3mpg empty drag racing. No better tax deduction than buying diesel fuel. Lol

Edit: guess since we were all 3 hauling Macks, that would be probably first time in history a Volvo climbed a mountain without the 4 ways on! Leiffi can pretend it wasn’t on the back of a Caterpillar.

 

[BRE]

Those fuel mileages are impressive. Lol
