Pressure washer engine - overkill?

[montrose818]

So the Briggs 16hp VTwin on my cat 5CP5150 (hah, even my pump is 5150) died. Its a 5.5gpm 3000psi. Since it came eith a vtwin from factory, I scored a brand new Predator 22hp vtwin to replace it with. Required some fabbing to the cart, but basixally... the thing is huge. I mean comparing the briggs 16hp to the 22hp predator is like a a prius vs a landcruiser.

Did I really overshoot it? It came stock with the vtwin, figured its should work fine.

Thinking HP won't matter as long as RPMs are right.

I recently replaced the pump on a pressure washer I got for free. It has a 16 horse honda and a 3k psi pump. I think I remember the paperwork with the pump saying it was safe up to 25 or something. I think you'll be fine, realistically the pump is what demands the power so a bigger motor shouldn't hurt the pump it'd be the other way around. Your pump could probably kill/stall a smaller motor. The 22hp motor just won't work as hard to turn your "16hp" pump.

And lets be real, the china 22hp pump is probably gonna produce 16hp. lol

As above.

The only problem I can see with too big of a motor in this scenario is the possibility of the pump overshooting on the pressure when the wand first shuts off.

IE, unloader valve not reacting quickly enough or with too little flow.
