C13 twin turbo

Paystar · Dec 31, 2014

Last post, I don't want to argue. Maybe I'm lucky, but have a few Cats here with 1.5 million km's that have never failed. Only had regular bearing crank bearing roll in as preventative maintenance and Cat made us replace the turbo and water pump to renew the extended warranties.

Yes I agree with shimmy n14 ddec 3 and older 12.7 are great engines but I think a c15 is just as good. I can see your opinion if comparing these three to c13 but wouldn't a c13 be considered a newer design more comparable to later model Cummins and detroit even though they over lap in years built.

Yes, will agree completely that C-13 and ISX are equally no good. I am not trying to get in last word, but 1.5 M kilos is 900,000 miles. Let's talk in a year or two. :beerchug

so the ? remain's is such a thing as bullet proofing a C13 if you had to rebuild one what would you change would it be smart to go to a single turbo

I would say so, and get the breather plumbed to the outside air. Why on earth would you want an engine burning soot and the like? As far as the turbo situation, the only.problem is when you go to a single turbo, you are going to have to change the ECM programing or it will be slower than a 60 Series.
Those silly things with twin turbo make like 65-75 lbs of boost. (And we sit around talking about why they don't last):duh

didn't know that they had that much boost .never driven one been around bulldogs to long I guess had some 3306's and 3406's years ago. talked to a friend that plays with a bunch of C15's and a few C13's he talked about having to reprogram with a single turbo. he said it could have a cracked head with it smoking white. ok going to bed got to run the 350c again tomorrow it used a about half a tank of fuel today used the ripper this morning in sp mode then bucket loading concrete in H mode

C-13 Acert makes 42 lbs of boost as new.

probably why mine was junk.... Was always around 60. Even had butler run it on the dyno an entire day. They claimed it was running as good as a new one.:Banghead:Banghead:Banghead. :waving

The boost depends on what the engine likes. If it is putting out the correct hp at 30 lbs of boost, it's good to go. If it's putting out the correct oh and 69 lbs, it's good to go. You are better of comparing to the dynojet run from the factory.

So does it automatically change boost pressure to get required HP ?or does it depend on what program is in the computer

Will do, because those engines are going into new gliders.

Boost pressure will vary according to the output of the engine. Like was said earlier, each engine is different enough no two will ever be the same. The ecm program determines how much fuel the engine gets, and then the boost just happens. Here's a good scenario to show how important exhaust is on a truck. On my 9900 with the N14, the muffler rotted out. IH wanted $1100 for a muffler, we said hell no, put a Grand Rock Resonator on off off a Kenworth. Since the back pressure was greatly reduced, the engine made another 2-3 psi of boost, and ran about a 100° cooler.

Polish your compressor like a wheel and you will get the same gains.

Explain?? You have proof?

DoyleX · Jan 2, 2015

I built a monster 855 some years back. Polished the machining marks out of the housing and gained a couple and lost EGT's. Got tired of re doing it all the time because of tarnish. A also got tired of going inside em all the time and neutered it to a comfortable 600hp

How are those C13's working out?

Multiracer · Apr 1, 2017

Mine only has 350,000 and still doing well.

Brodiesel · Apr 1, 2017

C13 KCB seems ok. Stay from C13 LEE, thats my two cents, Ive worked on both of em.

Multiracer · Apr 3, 2017

Good to know, mine is KCB. What are the differences ?

Brodiesel · Apr 4, 2017

The main difference is the LEE has a different emissions system, it uses an ARD head.
