Thank you for the reply, sanman....
The main reason I've been tinkering with the infinity jets is that I can get away with using a much cheaper/ smaller/ lighter pump to get the same suction results as a power jet with a larger pump.
I can run a 2.5" infinity jet with my 52gpm semi trash pump believe it or not, with decent suction... I only supply about 25gpm @ 30psi.... and get about 100 - 110 GPM through my 2.5" nozzle, at about 7 fps, with a total of 125-135 through the sluice. That's with my pump full throttle, and working shallow.
I truly believe I can design/ fabricate an infinity jet for a 4"... powered with a Honda/P90 pump combo.
If the pump can supply me 50-60 GPM at 70 foot of head (30 psi), I think I can get 250gpm draw on a 4" nozzle for about 6-7 fps. Not sure what the performance would be like though... is that a good velocity for a 4"?? I never used a 4"... only 2.5 and smaller.
Thanks for the advice sanman... you're always helpful with my builds.
