I have been running without my power steering and A/C for over a year now and from my perspective I preffer driving without them both. The only time I wish I had A/C is in the rain when the windows fog, but...ehhh.

The reasons I did it was to clear up space in the engine bay because I think it looks a lot less cluttered and cleaner, drop some weight (those components are really heavy especially the brakets), and make some cheap HP & TQ gains. I still have not gone to the dyno because I am lazy but the biggest thing I noticed was the engine reving a lot quicker. There did seem to be a bit of a boost in power but that is on the butt dyno and nothing scientific. I also added the CTR N1 crank pulley to shave a few more lbs. and also removed my cruise control. All this I sold on eBay and bought other mods with the money.

Basically it really is a prefference thing for people. I never used the A/C and preffer to drive without P/S...for me to take these systems off my car was a no brainer. For other people they may like to have them. If you do remove the P/S definately get a breather kit to keep the rack lubed and prevent dirt from getting in there.
