2007 Roush supercharger question

I am currently looking to potentially purchase a 2007 Roush 427R with 19,000 miles on it and I have one big question. I have had several Roush mustangs in the past and have never experienced rusting on the pulley assembly at the front of the supercharger as shown in the attached picture. Has anyone ever seen this type of erosion or know what may have caused it. Car is spotless otherwise. Gas Auto part Handwriting Wood Automotive tire

That’s odd. I’ve not seen that either. Where are you from? Only thing I can think of off the top of my head is potentially it just sweated over time. Or something leaked on it; some sort of moisture.

I’m going to take a really wild guess at this, so please treat it as such …

The front seal of the compressor failed or the compressor was rebuilt. Either of these require the removal of the front pulley/nut. The pulley was messy, so the person who serviced it cleaned it with an excessively strong solvent, removing paint and oils. This allowed rust to easily form even with light moisture.

That’s my guess, take it for what it is …

Sounds like a good guess. Do you know if these can be replaced? I know from previous Roush ownership that some replacement parts are hard to come by.

You certainly can replace them, but you’re on your own finding one.

If it were me, and I were bothered by this, I just remove it, clean the rust off, and repaint it (or send it out for powder coating).

Or is the car victim of one of the recent floods? Been a lot of that lately. The cars are being shipped out to many unsuspecting areas around the country. I have seen many car haulers on the road with vehicles that have plates from such areas out here in high and dry Idaho. Very suspicious. Hope I am wrong.

Might take a peek under the carpet or trunk liner...
