Dual nozzle-Julio kit

[vacuum 6]

Hey Julio at what point (HP/ET) do you recommend dual nozzles? Got a new motor in the works and it should run low 11s easy. Thanks.

Typically ~125 MPH=high 10's.

Best way to determine this is "T" in a pressure guage and see if your system is running higher than 150-170 PSI pressure to keep it from knocking. You add the additional nozzle and turn down the controller and work your way back up.

Dual nozzle is harder to dial in.. get your prelim tune and then make those decisions. I have customers on single nozzles mid 10's 130+ MPH.

Just depends.

Just to make sure I understand the psi correctly. Typically if running psi higher than 150-170 to keep knock suppressed then a 2nd nozzle is possibility needed. I dont want to go 2nd nozzle unless I have to.

Its about orfice, the larger the orfice the more you can flow with less pressure. Once you start running real high pressure on a single, then increase orfice to reduce pressure and have the same volume. By reducing pressure you draw less current and increase headroom on the system. Example your maxing pressure at 23 PSI... motor goes to 27 PSI and you dont have any more than you had at 23 PSI. Adding another nozzle, pressure brought down at 23 PSI.. goes to 27.. Now we have the capability of additional flow.

But without pressure data.. its all guessing.
