depends on what your going for and i think you mean UDP. lightweight will give a slight increase in horsepower but maintain the factory size pulley meaning your accessories such as radio and headlights will not suffer. the UDP you get slightly more power, but at the cost of possibly headlights diming or radio volume lowering. however i believe the people that do have the the UDP on the cobalt have no experienced either of the above with mrz's UDP. i could be wrong just what i read.

If You are looking for every little bit of power the UDP is the way to go. It slows the alternator and AC compressor by about 10% -- that means instead of spinning around 13,700 RPM at 6000 engine RPM the alternator will be spinning at 12,800 RPM, AC compressor will be similar. That means the engine doesn't have to waste the energy spinning the accessories for no reason -- instead it can deliver a little bit more to the wheels.
The alternator is still capable of putting out enough amperage to fry every electrical system on your car (with or without the UDP pulley) -- it is regulated so you do not lose any power to your headlights or radio or any other electrical device -- you do not notice any difference.

The shop is now moved completely in our new location. 2800sq. ft. to accomodate our machine shop, office and everything else :P That will help us get more new stuff done and increase our productivity on the parts we manufacture.
Alternator pulley will get done in the next days now that we have moved everything
