Calculator says I need 4 GPH nozzel.......

Clay · 03-12-2008

but the kit came with a 3 and a 7 GPH nozzle (Hey, wheres my 12 GPH nozzle?!?!). This is with the following data: 6500 RPM 20 PSI 2.2 Liters So short of buying a 4 GPH nozzle, I thought, why not find out what PSI I should need a 7 GPH nozzle. So I played with the calculator a bit, and it said at 30 PSI I would need a 7 GPH nozzle. So my thinking now is, I put in the 4 GPH nozzle, but set the max boost to 30 PSI. with the PCM control of the pump, will the 7 GPH nozzle act like a 4 GPH nozzle at 20 psi? I hope you guys see what Im trying to ask. Basically set the controller higher than my actual boost setting, so that its not achieving maximum flow at my boost set point. thanks, clay

You can make it a nozzle act smaller by doing that but, usually will only work for closer range. Make a 6 act like a 5 etc.

Our older kits with the inside mount nozzles came with 3 nozzle. The new nozzles are more expensive so keep the kit price down we went to 2. Most of our compators kits come with 2 nozzles also.

Ok, so then the better thing to do is actually get a 4 or 5 nozzle, correct?
