single fogger wet NITROUS EXPRESS EFI kit. have settings for up to 90 hp. would like to know the following–

jettings for fuel and n20 for a 100, 125, 150, 175 and 200. basically 100 to 200 in 25 increments.

dont have the time to take a 30/50/90 jet, do the pie times radius and sq root to get orfice size then use the “known” findings to figure out the devations from one size to another. and i know shit cant just be double of what a 100 shot is for a 200 shot

thanks in advance.

doesn’t NX list thier jets the same way as NOS (i think) you can just convert with online calculators…

is the one i used, it’s going to be dependant on fuel pressure also
