Now on the fuel solenoid you'll have a set jet size, but how do you control the fuel pressure going to that solenoid to match the "same amount of nitrous at all rpms" with fuel at the same flow at all rpms unless you can control exactly how much fuel pressure the fuel solenoid is seeing at all times?

The fuel jets are designed at 40psi of fuel pressure. Any more fuel pressure than you'll be running rich or lean out with not enough pressure.

Re: DIY Nitrous kit guru's thread

i had a wet setup -single fogger. no rpm window, just a micro switch on the tb and an arming switch. i'd launch and just not put my foot right to the floor, then once i hook up down it goes and back the head snaps. you will probably want a couple relays to run the solenoids off of. getting a fire extinguisher filled with n2o might not be so easy. the place i went to wouldn't fill my bottle without a pressure guage on it. also, is there a tube inside the fire ext. bottle? most n2o bottles have them i believe. i'd definitely recommend a wet setup. you do NOT want to run lean when the n2o comes on. and if you are using it from launch you definitely want to make sure you are in gear! i once saw a guy line up at the tree and put is foot down not in gear. his engine spat out his crank through the oil pan... messy :P
