Here's a video of my snow stage 2. The advertised pump output is 150 psi, and I am only getting 80 out of it, almost 1/2 of what it should be. This is not going to work to with boost pressure around 65psi. I want to upgrade to the 250, but am concerned that it wont actually produce 250.
CM pumps come set at a true 220 PSI and can be turned up to a full 250 psi if you have large multiple nozzles. No matter its far better than a hopped up surflow that Snow uses from everything I have seen.
