Running without supercharger belt..Will it hurt anything?

I have ordered two new belts, jackshaft to SC and crank to jackshaft as my originals were fubar. Right now I have removed them and am just running the accessory drive belt. It seems to run fine (albeit much less power). Should I have done anything else and will it hurt anything to run it like this for a week until my belts arive.

You need to tie the bypass valve open if you are running without the supercharger belt.
