so im trynna figure out what jets to use on a fogger nozzle to run a 50 shot on my 3800.

i have a NOS super pro-shot nitrous solenoid, and a NOS fuel cheater solenoid. both running to a NOS fogger nozzle going into my throttle body

car is fuel injected (99 regal) and im running probably slightly higher fuel pressure due to having a walbro 255lph fuel pump.

so how can i figure this out?

im hearing around .030 nitrous and .022 fuel, but im hearing anything from .017 fuel and .032 nitrous to .032 nitrous .042 fuel..... wide variation there

detroit speedshop was the only place that said you add more fuel than nitrous, but they might have been looking up through tables that had setups running much lower fuel pressure.

so any help with determining a good starting jet size for fuel and nitrous would be GREATLY appreciated.

if anything, id like to favor smaller than 50hp shot, instead of over

thank you guys!

PS: what kind of tap can i use for a fogger nozzle? anybody have one i can literally borrow for 10 minutes? lol


thanks!

thanks for the help. i ended up using the charts off the 02 regal instead of the 99 (because my motor is technically out of an 07 lucerne anyway) and because i have an aftermarket fuel pump that runs a higher pressure i believe. so the 2002 regal is listed with a higher flowing fuel pressure than the 99, i bought the 31/18 jets for the 35 shot and 35/18 jets for the 50 shot. i figured this made more sense because they are the same car but one had slightly higher fuel pressure.

thanks again for the help. i figured id err on the side of slightly smaller fuel jet because of the walbro i have in there

thanks again

the fuel pump doesnt have alot to do with pressure. if it still has the same regulator it wont change alot.
put a gauge on and check it
