I plan to start running autocross this weekend. I've heard and read about the power steering pump not being able to keep up with demand.

1. I'm assuming this is only in extreme circumstances such as slolom. Yes?

2. Is there a better pump to replace the OEM?

I'll admit up front I have not looked into this yet, so apologies if this question has an obvious answer.

Yeah, I've been thinking about this some too...What about a pump from a Legend coupe? Something able to handle the excessive weight of our front driver yet not too soft...would there be any way to swap out the pump for a difference honda/acura pump?

I don't think I have noticed it yet either. If I did I just didn't realize it.

No...if it did happen, it's impossible not to notice it. It just hasn't happened yet

Does anyone know if there's a manual steering rack available for the '99 SH...? I hate the power steering unit - it stiffens up in some tight corners.

Yup...it feels like you're trying to turn the wheel when your ignition is off and your car is in park.

Nawh...that's kind extreme, but that's what it feels like all of a sudden when it kicks out. Being smooth helps out a lot...

Have you read the literature that came with the car-sorry to rag but it clearly tells you that the power steering works to a setpoint and then shuts off. My dealer tells me that this is the case above 15mph. Anyway-to the best of my info there is no Honda part that is available for a conversion to manual steering. Have you driven a 3200 pound (includes driver and fuel) car without it lately. My Civic HB is hard to deal with when parking-great for cornering fast. The Prelude is very similar if you drive smooth and keep the speed up.
Just my observations.

I've had it only happen twice and both times I was doing less then 15mph. I whipped into a parking ot once just screwing around and the other time I was going slow by my friends street and cut into the block then into his driveway...that was under 15mph as well. It SUCKS when it happens!

If you find one with the same or less turns lock-to-lock, let me know. I have searched, but with no success.

This is true to a point. FYI, the 4th gen and earlier Preludes used a speed-sensitive system that had a pressure regulator driven by the speed sensor in the tranny. P/S pressure in the rack was regulated by this dude, varying with actual land speed.

In the 5th gen we got ripped off. They went cheap, and do all the regulation in the pump itself. Therefore, assist is based on engine speed, NOT land speed.

The problem, as I have experienced it, occurs near redline (maybe above 6500RPMS) in first gear- makes sense, you're going relatively slow and losing assist, possibly even fighting the pressure that's in the rack, or at least the pump. I haven't heard is the 4th gens have this problem, but it doesn't take a genius to see that's it's a much better system.

For anyone who cares, in the course of all my 4WS research I also looked at a 4th gen p/s swap for the 5th gen. Forget it. New pump, new rack, new lines... it's not worth it.

There also is a p/s pressure sensor on the line to the rack that goes to the ECU. Anyone know what it does? There's no signal or control back to the pump or rack, so the pressure is for input only to the ECU. I haven't been able to figure out what they hell it wants to know that for. When I disconnected the pump and ran the car, the ECU didn't care (so it's probably not for failure detection).

Nope, Going to the one at Triton College. It's a TSSCC (Tri-State Sports Car Council)meet. A family member is director of the organization and promised I could be "Honorary Cone Boy" if I show. Should be fun!

Well, it only really occurs when you are driving hard and fast. You will need a better technique when you start driving faster on the course. When you are driving too slow, you dont notice it. When you are driving fast enough to actually take cones and such, then you will notice it if you are driving too hot and not using the gas properly. You need to squeeze the gas and use it to exit the turn so you get the engine at the right speed to help the exit and any turning needed. It starts to not be a problem the more you do it.
