Ran a 6-inch cutterhead suction dredge for a month on the Snake River, then switched to an 8-inch with a trash pump. The difference in how much gravel we moved was crazy.

Jumping from a 6 to an 8 inch is a huge step up in volume. The trash pump must have really helped keep things clear, less downtime from clogs. Bet you saw the pile on your sluice double in size some days.

The volume jump is no joke. Did you have to change your whole setup to handle the extra material? I'm curious about the sluice angle and water flow you ended up with. My old 6 inch setup would probably just choke on that kind of feed rate.
