    What can stop your turbo from getting air? Trying to narrow it down.

    A clogged air source.Filter is#1.All the pipes including the air cooler are #2. If you're getting too much fuel, well I guess that would be#3.If your turbo is damaged and not producing enough boost, could also be a problem, have you talked to the person that did the work.

    I am not a expert. The turbo is driven by Exhaust to very high speeds in orange hot conditions. That is what drives it. Now the impeller inside that turbo is pulling cold air from the intercooler that has a big pipe feeding it. The air undergoes a certain change and is able to be fed into the combustion chamber under conditions mixing with fuel to burn more and longer to generate bigger power to drive that piston down faster.

    It's not to be confused with a super charger. A turbo engine in a plane will be really quick taking off but once it reaches a certain height it has asthma. But put a big enough super charger into a airplane engine above that height you have something that will run and never quit or fall down.

    The intercooler pipe to the turbocharger is yea wide. On it is clamps. If they are loose then outside air is compromising the internal condition of the cold air inside that pipe. The turbo will try to feed it but the engine wont like it and the fuel wont burn. The result is a inky black smoke straight up the stack with fuel oil in it, smears your trailer right side and blinds two lanes behind you for a couple hundred yards. Your engine's power turns into a 10 horse lawn mower and that poor truck is going to crawl at 15 mph if that. literally choking.

    That's all I know. Anything more than that, I leave to those who know better than I do.

    Update they have went through and tightened all hoses and clamps leading to or from turbo. Repaced a sensor, still no air. I believe they left it opened up in garage and got some crap in it...

    The blades on the turbo should be clean and completely damage free grab the center of the blades and try to move it, in and out, up and down, there should be no appreciable movement, spin it and make sure it spins freely without touching the sides. If it passes those tests it should be fine.

    Not to be technical, but...
    A turbocharger has a compressor wheel (cold air side) and a turbine wheel (hot air side). Both wheels are connected on either end of a single shaft and driven by exhaust pressure.
