There were two of us today both with van systems any way i have 60psi flojet pumps the other chap has 100psi sureflow.
We both had 100mtrs of mini bore and put them both on full flow and put them side by side to compare the flow.
They are virtually the same you couldn't tell the differance between them.
I thought the 100psi sureflow would blast it out more than the 60psi flojet but i didn't.
