    Turbo IDI intake air leak?

    Okay, issue solved... don't you love it when instead of the problem being extreme it turns out that you're just incompetent. So while I was installing the turbo kit I used a Cummins flexible oil drain into the CDR hole... turns out I never installed the freeze plug into the hole in the back of...

    Turbo IDI intake air leak?

    It sounds as if some type of squealing coming from the exaust.

    Turbo IDI intake air leak?

    Okay, so I checked the gasket for the intake snail and it is fit. I tried blocking the intake again and it still runs normal... whenever I rev it I hear a quick whining noise, that I previously thought was a belt or the turbo, but it's something near the rear of the engine.

    Core support swappout

    So I cover the ATS intake snail with my hand, expecting the engine to sputter only to have it run fine. Intake manifold leak?!?

    Turbo IDI intake air leak?

    Hey everyone, so I recently put a H1C on my 6.9 IDI which I mated to the previous factory turbo kit. I hooked up a boost gauge and took it for a drive; sounded great but lacked even a 1 psi. So I take the turbo off and leave just the up pipe and ATS intake snail attached. Then I put my hand over...

    7.3 IDI NA boost opinions?

    Yeah, but I think Maccrob had his with an intercooler if I recall correctly.

    7.3 IDI NA boost opinions?

    That's awesome, I've watched a few of your videos! Didn't you put a Borg Warner S300 or something on your IDI that had a Banks turbo? It hit something crazy, like 20psi!?

    Alright, I'll try to have it advanced by my local shop. Thanks for the advice man!

    7.3 IDI NA boost opinions?

    I'm thinking two flats should give me some boost to start with. Your thoughts?

    7.3 IDI NA boost opinions?

    I haven't gotten it timed accurately yet, it burns clean and smokes slightly, but black upon hard throttle. If anything it's a an alignment mark past neutral alignment. How much do you recommend turning up a stock pump?

    7.3 IDI NA boost opinions?

    So on controlling the boost it's up to how much I turn the pump.

    7.3 IDI NA boost opinions?

    Well mine is a non wastegate H1C and I'm currently at about neutral with my timing and I haven't turned up the pump yet. The turbo whistles, yet isn't pushing since the NA level of fuel. Can't even make over 1 psi on the gauge.

    7.3 IDI NA boost opinions?

    Well it depends, you've got stock headbolts I assume. I would say 12psi is my conservative max on that, others will say up to 15-16psi. I've just finished my H1C build and I haven't yet got a boost guage to see. Even with head studs I don't plan on boosting my engine over 15 psi.

    6.9 IDI White Smoke

    And mine surged intermittently when I first got it, after injectors and a new pump it was fine.

    Good luck!

    6.9 IDI White Smoke

    I wouldn't worry too much. It's running on the original pump from 86. I'd get a new fuel filter, add some diesel fuel treatment to it, order some new injectors, and then look at advancing the injector pump a tiny bit. My IDI never used ether and I couldn't tell what the problem was... until I...

    Dynomax 19430 Exhaust System

    Alright, so I bought a crankcase vent from Banks that extends the oil fill out. Currently I've got a heater hose attached to the vent that's basically a RDT. I've heard of people positioning it by the filter and letting it suck in that way or mounting the CDR to the aluminum pipe after the...

    Help diagnosing possible fueling issue SOLVED

    I had a similar thing when I bought my 87 6.9. It would be cruising normal at 50-55 and then seemed to actually get more power and then lose it. After replacing the injectors and getting a new injection pump all at once it seemed to have solved the problem.

    Dynomax 19430 Exhaust System

    That's awesome, I've currently got the factory banks downpipe on my custom turbo job. What type of muffler do you guys recommend for a deep note, but way less droning at 55mph+???

    Oil drain plumbing

    Well I took it out and punched a few more holes into it. Now with the H1C and flexible oil drain installed it seems to be draining. I've had no leaks yet... except for a return line, again.

    Oil drain plumbing

    Oh sorry man, it's a 1987 6.9 IDI f250, with headstuds.

    Oil drain plumbing

    Hey, so after installing my turbo I noticed oil puking from the CDR drain. I poked holes into it before, but it seems to backflow. Are there 2 layers of the splash guard?

    Thank you, I'm looking at the maps right now!

    Turbo problems

    The H1C is a T3 and the 18-21cm exhaust housings are considered gutless and low boost on a 1st gen cummins. Many cummins owners swap to a 12-14cm exhaust housing for more boost. So I'm thinking with the extra liter of displacement that it would spool quicker; yet wouldn't overboost due to the...
