Hydroboost on corvettes
There was a thread awhile back about teeing into the power steering lines to add a hydroboost to a Vette. Wouldn't it be simpler to get a power steering pump and reservoir for a hydroboost system? Also doesn't the reservoir need to be higher than the hydroboost unit to keep fluid from seeping out the cap?

I was not referring to brake fluid seeping out the cap. The low pressure power steering fluid return line on the hydroboost unit is at a highter elevation than the standard power steering pump reservoir. What is to stop the power steering fluid from flowing down the return hose and seeping out the power steering pump reservoir cap, which is lower?

The power steering reservoir is located in basically the same place on the vette as the trucks that we take the system off of and the hydra boost valve does not store fluid so the level of the valve is not an issue. You cannot tee into the pressure line of the power steering system. The pressure line has to go straight to the hydra boost valve and than from there to the power assist cylinder. The Hydra boost valve will proportion the fluid flow in order to keep both the brakes and steering working correctly. You can tee into the return line from both the hydra boost valve and the steering assist cylinder.

Neal, Are you saying you use the separate reservoir from the truck system on the Vette? That was what I was referring to in my original post. Using the hydroboost power steering pump with its separate reservoir. After more thought I realize there would not be enough power steering fluid in the low pressure hose to cause an overflow on the low mounted power steering pump reservoir (unless the pump was filled to the brim, which is an over full condition anyway).

There is something that I have been wanting to ask:
What is the advantage of using a hydra-boost in place of a vacuum booster? I am really curious abut this.
Thanks in advance.

Big cam, low vacuum, blowers, clearace issues.
BTW, I noticed what looked like factory hydroboost on my GF's '04 Mustang. With the V8, it didn't look like there was clearance for the valve covers.
I've seen some vette projects, ie hydraulic clutch, tall valve covers, that didn't have clearace for the booster.
