Nitrous pics

As far as setting up the system you need a flow tool which is essentially a fuel pressure guage with a .073 jet. You set the regulator pressure at 5.5psi to start with the flow tool and drop a half pound up or down to fatten or lean out the tune. Regardless of using a 100 shot or a 175 shot etc always baseline the pressure regulator with the flow tool.

I also recommend a fuel filter and a nitrous filter. My fuel filter is after the regulator so i can flow through it. My nitrous filter is before the 1/4 turn shut off handle by the shifter.

Also note that i get my tach signal for the progressive/window switch thing from the pertronix rev limiter box. The low deck Accell cable drive tach was converted to a Petronix with a matching coil so no place to get a tach signal hence the rev limiter box. Waylon in the 8 track too..
