How can I check / set the pressure on my FPSS.

How do I set the pressure of my holley blue pump and reg.

Finally getting this thing ready to spray, but want to make sure everything is working right. Also, any tips for reading plugs? Black = rich, and white = lean, anything else? I understand you have to shut it off right after the pass. I plan on making a few 'dry' runs but will take any advice you have to offer. Thanks.

for the fpss you need a hand held pump w/ gauge and a ohm meter to watch when it switch's from open to closed.
there r a lot of varibles as to what your combo. actually is .u need to watch what fuel press. is at full throttle first .if its stumbling on top then turn in the screw on the reg. to turn up the press.
u read the plugs by looking at the BASE of the porciline, u want a light tan ring . this is on a new set of plugs .
before spraying u need to set the flowing fuel press. to your nitrous fuel solinoid and what the manufacture recomends (most at 6psi)
there is a lot more but i hope this gets you started . it always help to find someone local that has a car that you know always good, to help with advice on tuning your car.

 

Use the plug color as a general indicator. You're mostly looking for extremes that indicate trouble, on the plugs.
Detonation, extreme lean condition Blueing piting, peppering porcelines etc

Start a little rich and a little conservative on the ignition advance and work leaner (fuel pressure) and up in advance.
Believe the track et slip over the spark plug color.
More MPH= more power.
Being a little rich will only compromise the power and small amout. Being too lean will cost you $$$

Always set the fuel pressure with the system flowing.
a volt meter on the fuel pump power lead + is nice to verify supply voltage. The pumps flow output will vary a little with the supply voltage.

Be sure to start with a gasoline that has enough octane.
Initially, more is better.

 

I run 93 in the tank and 116 in the fuel cell for the juice. Thanks guys.
