Trying to go bigger with the engine I have

[Infinity]

Estimate for First Home and Driveway combo

I figured out the other day on the phone with ibs that I’m over spinning my pump. At wife open throttle I was pushing 4K with a number 9 and still bypassing about a gallon a minute. I ordered a tachometer so I can set it properly. Pumps not rated for that so I’m just glad it’s an udor and didn’t crap out on me… Stepping up to #10 nozzles and setting the rpm Tuesday.
