Quick Jetting Guide:

100% water target 8-10% of fuel flow
50/50 mix target 15–20% of fuel flow
100% methanol target 20–25% of fuel flow

If you don't know fuel flow you can do the following.

Horsepower @ crank x .5  = CC jetting (pure water)
Horsepower @ crank x 1.0 = CC jetting (50/50 mix)
Horsepower @ crank x 1.5-2.0 = CC jetting (pure methanol)

For example. 1000 horsepower. You would use 500cc pure water, 1000cc 50/50 mix and between 1500-2000cc pure methanol. Keep in mind these are figures to start with and do not take into consideration all the variables that we have found to affect jetting size. There are many other variables to consider. If you need help selecting a nozzle size feel free to call us directly for technical help.
