I have 5.5hp briggs&stratton pressure washer Simoniz S2350. Would you know the PSI for this item?
Every 5.5 HP pressure washer runs between 2,200 and 2,500 PSI with most set by the manufacturer at 2,400 PSI with 3,600 RPM of engine speed.
Due to the power required to produce more than 2,500 PSI a 5.5 HP engine would lose engine speed as it can not produce enough power for the higher PSI output. It is a matter of hydraulics vs input power.
Any gas pressure washer will produce lower pressure with lower engine RPM. Looking at S2350 as your model number yours may be set to 2,350 PSI by Simoniz.
Thanks for using FixYa.
