Decided to re do the wiring for the nitrous, it was a quick job and wasn’t that neat, I also found this which is made by a company in the states. Will contain everything in little box so 1 is on the way
I’ve now drawn up (badly)
a new wiring diagram to work with with the control box, only need to run 3 wires from the cab to the back end now
I’m got everything I can to make it as safe for the engine as possible.
Hobbs fuel pressure safety switch, if the fuel pressure drops below a pre set pressure it kills the entire system, most nitrous failures are due to not enough fuel which results in a blow torch effect.
My Mallory ignition box has an rpm window switch. I can set what RPM range the gas will work in, I’ll go with 3500-7000. This is so if the engine bogs off the line it won’t cause damage
And a ‘Wide open throttle’ switch, this only activates the system when I’ve got it floored, which will protect engine during gear changes, if I let off it shuts down and will help consistency. Basically if it’s floored between 3500-7000 it will be injecting nitrous. So no red button and warp speed effects on the landscape as the fast & furious would like you to believe
