When I did it, I put out more water, more pressure, more
soap and stated so on a bay sign right above the
coin meter. When I did it I only had 3 HP motors and Cat 310 pumps. I did have to install a 5 HP motor, but many systems already have 5 HP and maybe yours does. I installed a bigger pump, but you may not have to, depending on how "super" you want it to be. A simple pulley change may get you to where you want to be. I went with an 08 tip and 1500 PSI, and it was definitely super. The good ole boys loved it.
