What's the average life expectancy of the C230K's supercharger (unmodified)?

I've seen figures for s'chargers in general ranging from 80k - 120k miles. Jabbasport, which sells both s'chargers and turbos and probably isn't biassed towards one or the other, says 65k - 75k miles for theirs.

I too own a c230k. The superchargers you're looking at have a very high psi (>10) compared to the stock c230k. In other words, aftermarket superchargers are generally more powerful and put more stress on the engine. For reference, the w202 c230k can still run well with more than 100k miles. Another reference are the really old turbocharged saabs (9-3 i think they're called).

So basically, as long as any unmodified engine. No company would put out an engine that wasn't at least designed to last less than 100k miles.

There is a coupler common to all eaton superchargers. This will start making noise between 40K and 70K. Cost is about $20-30. Is a good time to change supercharger oil.
