Good luck with finding one, I've been watching for a used one for a few months now. They seem to be pretty rare used and not available new. A used 2004 model one just sold for 2800 on ebay, pretty crazy for a 8 year old supercharer with no history.
There are always units for sale. Some used, and at times even brand new. Do not expect to
get them cheap. Full units with all parts have been selling at $3,000 and up. Very basic supply and demand in play here and HP for the 4.7
is not cheap.
Jamesjr4750 has done a great job of even posting units for sale as heads up. I wonder if folks read these threads.
Here is the thread:
There are plenty of answers on this board.
Start looking in the past if you want answers. As in... PAST threads.
Easy James. I hear ya, but, let me try to walk folks through this one more time. If they read it, they hopefully
will get it.
Considering buying a used one.......Checked on EBAY there was 0............Just looking for more Horsepower..
See above. (SC for sale)
Then, I recommend anyone considering a SC, please read some of the many threads in this section:
Forced Induction Systems
I did not do the search for you. I expect you can do that better than me. There is a wealth of information on the supercharger in that section.
**Caution to anyone that wants an SC:
1. Do your homework so you know the language and the parts.Too many people buy units with
missing parts because the seller and/or buyer have no idea what a complete unit looks like.
There is a lot more to the SC, than just the blower.
2. Most units for sale will be used, but, if complete, work great as is. Some folks have
rebuilt units before install (I just rebuilt a SC). There is also support in the marketplace
for this. I have not posted all of the resources, but, they are posted in other threads. See
that forced induction section, again.
3. Do NOT buy a supercharger if you really want 20+ MPG. Also, the SC requires premium gas, so,
if not prepared to do that, just pass on it.
4. If installing a SC is not in your skill set, be advised, some dealers may NOT want to install, but,
most competent shops with skilled techs, can handle this just fine.
This is the short version so I can help and avoid writing a novel. Just do some background
work and research so you know what you are doing.
***BTW, my supercharger is running fine and strong!!!!
