Default OK, Can I remove my PS pump? (Was "What's a good basic UDP?")

So, I thought "Why Not". Well, not take the belts off but I did try removing the alternator/PS belt to see how the car would drive. Took a quick drive around the block and backed into my driveway and garage. Takes quite a bit of effort when the car is sitting still, but is easy enough when moving even a little.

Has anyone removed their PS pump or at least re-belted so it's not in use?

If so, any downsides to handling other than forearm muscle development?

If the lines are removed and the fluid drained, does that improve the handling?

Finally, how much horsepower does the PS pump consume?

Thanks in advance,
Air

if you are trying to save some hp, take off the PS and the A/C compressor and all associated hardware. It wont give u much hp but it will sure as hell take off some weight

taking off powersteering probably won't make a huge difference, at least not enough to warrent its removal and the resulting pita you'll have to deal with all the time (trust me, had ps go out for 2 weeks in my supra, its ok the first few days, then it just pisses you off)

as for taking off the ac, yeah, someone took it off here and said it was ~22lb, without the refrigerent, which is probably a few more lb's

Thanks for the replies. I'll keep the PS for now. Sounds like minimal Hp gains, and I'm not looking at removing weight at this point. Just starting out and looking for things that work.

In another thread, I found a post that mentioned that the steering equipment wasn't really designed for full-manual steering so it was best to leave it on.

Thanks for your replies,
Air

refridgerant is 1.43lbs so make that an even 24 for the a/c system which IMHO is NOT worth removing, buy a Alumnium hood or CF hood and alumnium or c/f trunk lid and you'd spent your money MUCH more wisely

removing the PS can make the steering feel better at speed. You wont get a real gain in HP, but handling may be improved at speed.

SCC felt a beneft with a few of their project cars after romoving the PS belt and draining the steering rack of fluid. Obviously you will lose the benefit of PS at low speed.
