i grew up around cows, fella, so trust me when i say that i know bovine excrement when i smell it. :umno:
2.2 Million miles on a d12 LOL LOL LOL I am dying here. If you are going to lie at least make it realistic LOL You could have told me any Cat was at 2.2 million and I still wouldn't believe it unless I knew the truck. No brand bias there.
Yup it's true. The only issue is some blowby, volvos have always been the best at low blowby. See attached oil sample. He bought it at 1.6 million km (1 million miles) and the previous owner said no major engine work other than a few injectors. He's done a bearing roll which confirmed no inframe and a few more injectors. That's it. **** I think he's done two valve sets since 1 million miles.
Why would you change the turbos on the acerts?
What are the reasons to keep them? I can only think of two:
1) To meet emissions, Cat did this as a bandaid because they had no other way to do it.
2) If you want to run PRs higher than a single turbo.
That's all I can think of.
They can efficiently put 700+hp to the ground and drive better than any single turbo truck.
My detroit that puts out a measly 35 psi vs a 550 ACERT. I pulled on him a good mile or more going up Summit SD with a wicked sidewind. Same gross weight. I also get 1-1.5 mpg better than he does. Both drive similar, cruise similar speeds, etc. But hey he was sure proud of the 55+ PSI he was making! Now think about that, he had a 15L engine at 55+ psi and I had a 12.7 at 35. That means he was likely pushing almost twice the amount of air. Now compounds at 700+ HP might be the ticket, they might not be, but I can tell you for a fact there's no reason to run compounds before that from a BSFC/MPG perspective or even a HP perspective since they cost HP.
Lower EGTs? Who cares on a monotherm piston engine as long as the AFR is above the smoke point.
More boost? Why make more boost than you need to? You're just wasting power and fuel pushing around useless air that has no benefit. If you need a LOT of boost to stay above the smoke point yes compounds are the only way to go.
Pistons? That is probably the last thing I have seen replaced on an Acert. Their bottom ends are out of this world.
Then why are guys always putting in industrial pistons? Delete IVA's, more timing, stock compression = not a happy motor!
My business partner is putting some quality studs in the bottom and will be spinning his at 4000+ rpm in his puller.... What a bunch of junk.
Where should I send the congratulatory card?
