Hydro boost route question

[joshua]

I want to run both returns from the HB and the P.S. Box into the P.S. cooler as represented by pink. Black is that line deleted. I only have one return on my P.S. pump. I figured it would be better if I do have to combine the 2 returns, why not do it before the cooler?

The backpressure of the cooler makes the hydroboost mis-behave. The flow from low pressure return out of the hydroboost is a trivial amount. Not really any flow to speak of, just a return of fluid after a brake cycle. It would take a couple cycles of the brake pedal just to flow the amount of fluid that is in the return line. So it doesn't need cooling. But it needs to be free of backpressure.

I had thought about that, that’s y I asked.
