I'm running that combo in my Mustang. It works great, and I have very little crosstalk between the Hydraboost and Power rack. My PS pump is a KRC unit, so is my PS fluid resorvair. I also had the resovair fitted with another -AN 6 bung for the Hydraboost low pressure return line, instead of tunning a T.
You just need to run a PS pump that can handle the task, the KRC pump can easily change the flow-valve (big blue fitting on the pump) to get the gmp you need. Also the resorvair is big enough, so that you don't pump it dry.
The engine bay has been washed after this picture
Here's a picture when I installed it, the low-pressure return line isn't in that picture, because I hadn't fitted the extra AN bung, but you get the picture.
Hope this helped.
