Flow over pressure. With more volume will come more pressure. It's a given when trying to push more volume through the same orifice size.
Same with thicker oil. It's more volume (molecules in the same space) being pushed through the same orifice.
As far as 10% more pressure. If it's 30 psi before, it'll be 33 psi with the upgraded pump. 50 psi will he 55psi.
The 10 psi per 1k rpms is an acceptable range.
