Holset turbo rebuild part 2

[Beagle RC Air]

Here are some pictures of the damaged compressor wheel, new compressor wheel in the rebuilt turbo, receipt and Johnny Blodgett doing the installation.
Previous to rebuild, the Silverleaf showed 23.1 pounds of boost on hard pull. With the Aeroturbine muffler and rebuilt turbo it will be interesting to see if anything changes on the Silverleaf readout.

Beagle RC Air,

How did debris get past the air filter to cause the chipping on the turbine blades? I would be concerned about stopping whatever infiltration occurred.

Beagle,

Our Silverleaf shows our boost at 31 or so psi on hard pull. It quickly goes to the top of the 20's, at least. Perhaps yours had chipping or wasn't working properly before this incident.

OldForester,

On my 2006 Alpine, my Silverleaf monitor shows about 36 PSI on any hard pull.

Dale, those are good numbers, I believe the best my Silverleaf reports is 32. When I put the Banks kit on my 2000 Alpine I would see 38 but that also caused an engine code to appear. I was told 36 was max before the ECU reports an error on the ISC3350. Not sure what max boost before an error is on an ISL400.

I got a "Turbo Overspin" error when my 400ISL showed a little over 40 pounds boost on my silverleaf. The error caused a temp decrease in power for a few seconds until the error apparently self corrected with lower boost. Cummins in Yakima fixed it, but I'm not sure what they did. Cummins said the engine wouldn't let the situation damage itself. Now, the Silverleaf shows a max of about 36 pounds or so.

We have no way of knowing for certain what or when debris went thru.
Air Filter was changed out a while back and the seal was excellent and made proper contact to the filter housing. Also, the tubing to and from the CAC is clean. Johnny Blodgett (25+ years as hvy equipment/foreman) and another hvy equipment mechanic/foreman both thought that it was from assembly of components.
I am interested in what other ISC owners are seeing for boost. I don't think that numbers like some of you are seeing with the ISL series is going to be what I get.
Next thing is to get the laptop up and running so we can tell what the boost number is.
