no, the belt driving the charger is the serpintine belt that also drives the componants.. so if the belt goes the water pump , alternator , power steering and A/C will not turn... the car will run on its battery.. and if your lucky you got 15 mins before the battery dies.... giving the car dosent overheat due to the waterpump not spining....Joe

wrong, it is separate. you can run the engine without the supercharger belt, it will just suck miserably. you will have very little power, and disgusting gas mileage. visit www.clubgp.com or www.gpona.com for more information.

Yes, the engine will run, but it won't be very efficient. You can drive without a supercharger, I wouldn't recomend doing it for very long. But, no it won't HURT anything.

Jason and Joseph is correct. I had to drive mine for a while after it suffered a snout bearing failure. Gas mileage was about 10 mpg and acceleration sucked. Why are you wanting to run without the supercharger?

Ya everyones right except for the first guy. Of course you can run it but like they all said your power will suck. Its like taking a turbo off a diesel there goes almost half of your horsepower.

I have actually heard of people getting better MPG's with the belt off...

as far as i know, it really depends on the setup. the engine is designed for the extra air in the cylinders(forced induction) and if there is less air than it needs, it will run less efficently.

5yrs later... Our supercharger belt broke and the only thing I noticed was that the mpg in city driving went down 2 or 3 mpg to about 16 mpg. On the highway it still was getting 29 mpg which has been normal for around the past 200,000 miles. The performance when hitting the gas hard was also worse but not much worse than a non-supercharged 3.8l buick engine that we used to have in our LeSabre.

I have a 2002 40th anniversary edition, curious does the supercharger belt run anything else?
