please help me idk if i put on an under pully if it will affect my compressor for my

It's been over 100 degrees here for weeks now, and I've been driving 45 minutes in traffic each way to work in it with underdrive pulleys and my air conditioning is working great, along with everything else. No overheating either.

Just make sure you get a set of non-piggyback pulleys like the Steeda. Piggyback pulleys are cheaper, but come with other troubles instead. Pay the extra money for the ones that come with a new SFI approved balancer.

If you've got an '07, you should be asking this question in the S197 section........

The only thing I noticed was in neutral it revs a little quicker. Whether that translates to being faster on the street, I'm not sure.

To be honest, if I wouldn't have gotten mine used for a good price, I wouldn't have bought them.
