rebuilt supercharger

I have a '93 Bonneville with the supercharged 3.8 liter engine. When
the supercharger started making suspicious noises, my GM service
center told me the only option was to buy a new one from them for over
$2400 + labor to put it in. In doing some checking, I determined that
there is an alternative that is much more reasonable. Magnuson
Products in Ventura, CA (tel 805-642-8833) sells rebuilt superchargers
for $1,100 plus a $200 core fee (refundable if yours is usable) plus
$50 shipping (covers both to you and return of your old unit to them).

I lucked out even better. They had a "cosmetically imperfect" unit for
$550 plus core fee and shipping. According to the tech I spoke with at
Magnuson, these units are mechanically perfect and he'd use one in
his car, so that's what I bought. The "blemish" was that the covers
were from different cars and were therefore different colors.

Put it in four days ago and it's working perfectly. I realize that's a
short time, so if there's any change, be sure that I'll post it here.

Magnuson also sells "nose cone kits" if only the bearing is bad.

What's really annoying about my GM service center not knowing about
this is GM put out a Service Bulletin in 1999 pointing out that
Magnuson was a source of more economical units when the customer had
to pay for it (as opposed to warranty, where they have to put in a new
unit). If anyone wants it, Magnuson can fax you a copy. It's labelled
Bulletin #99-06-01-012 dated July 19, 1999. Magnuson is a factory
authorized rebuilder (the only one according to their literature) of
Eaton superchargers -- which is what GM put in their cars.

I also found Magnuson's people to be really helpful. Highly
recommended!

Hoping this helps others in a similar situation.

That's good to know.

What would happen if you con't to use your old supercharged? I have a
supercharged on my 93 Bonneville SSEi as well. I have over 190,000 mile
(306,000Km) on this engine and it is still running fine. I have been
monitored the oil level and have top it up once complete supercharged oil
from GM (very small bottle) within a year period. I am wondering how long
will this supercharged is going to last and what would be the sign of
failure when it starts to fail?

AFAIK, the two main modes of failure of a supercharger are the
bearings going boink and the supercharger ingesting something it should
not. For the first, well, you can notice it when turning the charger by
hand: if it is noiser you know it is time to consider replacing
bearings. The second one usually leads to lower compression/boost.

Martin,

Are you the original owner on the car?

Did you ever change ( siphon ) the supercharger oil ? say once a year?

How many miles does the car have?

Just trying to gage how long these things last.
