Hydro Boost and power steering pump pressure.

[Perry Stapleton]

Just converted to Hydro Boost. My stock power steering pump makes a noise and the steering is not smooth when turning and breaking at the same time. Anyone else have this problem and did you upgrade your power steering pump? Thanks

How is the system plumbed? Particularly the HB return line.
With the engine at op temp, and some time on the drive cycle, stop & take a look at the reservoir. Oil misting out? oil very hot, full of bubbles?
I think Turn One has a good pump for this app.
Others will chime in.
I've never had the problem.
FWIW, the factory had a recall/tsm on the stock system boiling the fluid. AIRC, they changed to a larger reservoir.

There are a bunch of discussions on the board about this issue. Send your pump to Turn One or Lee Steering. You can also get a new reservoir to hold more fluid and with better flow characteristics.

Has 2 returns to the pump. Use a T to merge the return. I will check for heating and fluid bubbling. I bought the car in 92. Don't know about the recall. You are using HB with factory pump and don't have a problem? That is interesting. I wonder why some do and others don't. Maybe the recall and larger fluid reservoir??? Thanks

That can cause issues.
Direct to the reservoir is preferred.
Thinking back, I may have put a Borgeson flow valve kit in the pump. Been a while.
