Has anyone had this problem? All other plugs look great if not rich... I am using 52/35 jetting which should be dead rich. (NX kit)

over 60# fuel pressure, 1000# bottle pressure. Could it be just the physics of reaching #1?can the fuel in a wet sytem make that hard turn in the intake? OR Do I have a more serious problem? Car runs great with new plug, I want to drive for a while and see if this cylinder looks lean on motor.

Any ideas?

 

between MAF and throttle body on drivers side, about center of hose.

Where do you have your nozzle mounted?

 

anyone?

 

I think your initial idea of running the car without nitrous and pulling plugs to see if its lean on motor is a good starting point. If that checks ok maybe start over again with a small shot while checking the plugs right after a WOT spray run. If its still lean I would adjust the aim point of the nozzle and try again.

Anyone else actually run into this?

 

What size shot are you running and what other mods do you have?

 

its a heads/cam car with all bolt ons, running around 100hp shot. actually 100hp n2o jet (52)and 150 hp fuel jet(35). I have in line fuel pump to make sure it has enough fuel. o2's read .93-.95 on spray.
