Destroyed compressor blades on stock turbo.

AWDTerror · Sep 6, 2009, 01:55 AM

So driving back from a get together, I'm going up the driveway to my house and as it starts to spool I hear this weird weezing noise that is really not supposed to be there. Soon as I get to the drive way, I shut the car off, pull the intake and the compressor blades are all bent and messed up.

Intake Mod:
HKS Panel Filter

I'll post pictures later.

You are lucky none of it broke off. Warranty should replace that turbo for you. It has to be some sort of manufacturing defect with only a drop-in as a mod.

I have a megan racing exhaust with AGP I/C piping, not of which would effect the compressor side of the turbo, and the only thing pre-turbo is the filter.

you sure nothing fell in there when your filter? I guess that's pretty hard to do as it would have to go through the MAF.

Turbo damage

Looks like a piece of compressor blade broke off and caused all the havoc, all I found trapped in the FMIC was 3 small pieces of blades.

damn thats insane lol ya warranty should cover u

There's only 2 ways you see that type of damage:
1) Compressor wheel injested a foreign object
2) One blade on the centrif fractured, seperated, and lodged into the other blades - This is either from material defects or modal excitation (sorry to go all Engineering speak here)

Either way, you're going to have pieces in your IC pipes or lodged in your IC.

Either a piece of cast come loose or a piece of overmolded plastic from the intake came loose or #2, I'm leaning toward #2 since all i found in the IC was pieces of compressor blades.

A piece of plastic shouldn't be enough to do that. It'd only slightly damage the leading edge of the blades - you wouldn't even know it.

AWDTerror · Sep 6, 2009, 01:20 PM

you'd be surprised.....remember the blades are spinning at 80,000+ RPMS

I agree it's possible, I just don't see it likely. I'm used to seeing what sand particles will do to axial compressor blades over time, so I'm just trying to draw a comparison in my head. A small piece of plastic should just get eaten by the wheel.

now what of the chances of parts getting past the intercooler?

►EvolutionX◄ · Sep 6, 2009, 02:59 PM

Your intercooler is almost like a filter. So the chances are quite low, anything small enough to get through there shouldn't cause MAJOR problems.

Oh a piece of plastic is PLENTY to destroy a turbo.

foreign object.

you sure you did the drop in properly?
