Kawickrice 14 Report post Posted February 27, 2011 I have a 3500 psi 4gpm belt drive pump with a Honda GX 390 engine and was curious as to what I should expect in the real world as far as real pressure vs advertised pressure. Is there a plus or minus I should expect. I have not gauged the pressure yet but I plan on doing so soon and was curious what to expect. The search button was not real helpful so I started a thread to find out what you guys experience in the real world. Thanks guys and gals Share this post Link to post Share on other sites
