Turbo disaster - idiot !!

Long story short , sucked rubber through intake due to my resonator delete, rebuilt turbo , is spinning but not enough to make boost . Their is a blocking of rubber somewhere in the system somewhere 😐 my brain is gonna explode!!

how does an exhaust resonator delete result in rubber going through the turbo?



when you say sucked in im assuming it went through the compressor side.. if thats the case did it wreck the compressor wheel? if it did then likely metal and rubber both went into the cylinders.. id start by making sure the engine runs on all its cylinders.. similar events ive seen often end up in bent valves or broken / cracked pistons..


what engine?

All the rubber was shot over to the passenger side plenum . Nothing was on the driver side of the intake manifold

lmao

Sorry.

Try looking in the intercooler if it has one. Other then that, there's nothing between the turbo and the engine to "catch" anything. If you have no boost, and the intercooler isn't full of trash, the turbo is likely junk.

Remove the intake and see if the wheel will spin freely, like really freely. If it doesn't, either rebuild or replace the turbo. You can get chra assemblies for cheap that are ready to install.

Are you sure your wicked wheel is not loose on the shaft (when under load)

Glad that was a relatively painless fix, and you thought it through before you pulled a head...

Before you post about the next adventures, fill in your profile info so people know what bus you're working on, and where you are!

Great news!! and also good that the turbo sent oil through the Turbine side and not into the intake.. too much oil in the intake and you can run the engine away.. ive seen a 7.3 run away because of a failed turbo..



wit hthe supply chain crisis im thinking more about rebuilding mine and upgrading to a WW2.. how do you like the WW2? im looking for more low end boost to ease my EGTs which can get up there if im not careful till my RPMs are up..

I'm interested to hear about the WWII as well. I've actually got one sitting on my shelf for my same year and engine F350 (1999). Glad you got it sorted.

If the WWII are made here it should not take too much time to get one.

To the OP glad you found the problem.

WW2 is great , spools up allot faster more noise for those who love the 7.3 turbo sound !! Especially withe the intake resonator delete !! It is an easy rebuild !!

this is one of the turbos id REALLY like to use as it maintains the 1.0 AR turbine which the 444E already has.. I like the 1.0 turbine for lower RPM heavy fueling applications which is what a bus typically needs..



it comes with a WW2 already installed and its ball bearing.. but its never in stock..

someone else has suggested the KC300X but that seems more like a higher RPM application looking at its specs..

My turbo is a lil different , mine doesn't have the waste gate on it , I'm not sure if that would be an option for my short bus . My rebuild came with all new oil seal clips 360° bearing , WW2 , n all that internal jazz !! Was super simple !! I'm not sure what u are running , but my turbo is different than f series turbo . Was the turbo u sent me on that thread over sized or sum ? Cuz u might save allot of money jus doing a rebuild like I did . That's if the turbo is the same one u have I had to order a used one cuz my external bolts were destroyed due to Pennsylvania road salt . But she is a super clean bus for Pa standards haha

Mine is non wastegate and I run 30 psi at high rpm . With 1.0AR turbine and compressor, my back pressure must be horrendous.. I want something that spools early and I can gate it before back pressure gets too high. The newer 444e all got gated turbos .. 02.5 plus, but prior only the high torque units got them . They were a GT37 which is smaller but soooled quicker ..

I don’t necessarily like 30 PSI on standard bolts.. if it was studded I wouldn’t think twice..
