need help from nitrous gurus

#1 Post by rustbucket » Mon Apr 14, 2008 11:32 am

went to the track sunday. The problem is, ive been chasing a surging gremlen. Use too, the car would surge down the track on motor or nitrous so I replaced my fuel line to feed the motor with 1/2 inch.(from the cell to the carb).That corrected the surging problem on the motor. However, its still there on the bottle.
heres the combo.
dedicated fuel system for nitrous consisting of.
1 gallon cell up front
mallory 140 fuel pump
bg bypass regulator
big shot plate with 225 jets. (not completly square jettet but a little leaner on fuel than nos recommended)
6 lbs fuel pressure
900 lbs of bottle pressure
timing retarded 6 degree with a msd retard box.
plugs look good ngk4554

any ideas? this problem wont go away :?

What type of nos selenoid? Have you taken it apart and checked the plunger to see if the rubber pad is swollen
