the pump can supply 1.8gpm at 60psi ,razor runs well over 100psi
an M10 nozzle flows 10gph (not per minute) at 100psi
higher pressure more alky , lower pressure less alky ,
if running more boost pump runs faster and pressure will be higher , if your not running much boost pump runs slower and pressure is less so less alky flows.
typical use is 1 ounce per second ...running a full minute you'd be going really fast and have covered alot of ground . at the track you're in it for less than 12 seconds and going well over 100 on stock turbo , with a larger turbo tuned you could see 120 ,with tubo and heads 130 , 140 ... speeds way too fast to be going with a 20yr old brick with drum brakes on the street .
and depending on your needs the system can have dual nozzles ..duals can be 2 m10s or m10 and m15 or if you need more 2 m15s so consumption will increase
