Opinions on cause of LSA blower failure?

This blower failed. Just looking for anyone's two cents about why.

Bearing failure and the rotors smacked the edge of the case and then each-other.

This...

Could be material found its way into the bearings...

Stock blower and no upgrades? Was the blower replace for isolator issue? What year ZL1?

This sounds correct. Later the two front bearings were found to have a bit of play in them.



It was a ported blower I used for one summer then sold. The new owner only got about 5 hours and 9 dyno pulls out of it. It was originally from a CTSV (it did not have a port for NPP) so it has been through a bit of use.


I told the buyer I would make a deal with him to refund some portion of money. It sounds like it is just a normal failure of a used part. But I feel like that is a little to soon to fail to claim it was a good blower.

What we see is the oil and other compounds present in the PCV vapors ingested adhere to the rotors and bake on, over time this throws the balance off and bearings soon fail allowing the close tolerances to not be enough so contact is made and it goes downhill fast from there. Hopefully you will not have any engine damage from ingesting the debris.


Our Catch Cans systems eliminates most all of this, but the damage is done. When you replace it, consider adding the proper air/oil crankcase evacuation system form us to prevent this in the future. And of course, ask any questions you may have.
