It might be off topic but I will be short. I tried to use 5 HP electric motor for my rig. I only could get 600 psi of pressure @ 18 gpm flow before motor overloaded. I needed at least 1000 psi. I installed 15 HP gas engine. I just have enough 1000 psi @ 18 gpm. I am really surprised 15HP 300% more then 5HP but 1000 psi is only 67% more then 600 psi. Do I miss something? or this is another example how to make money by inflating numbers?
