Help with nitrous setup and MSD 6AL box.

[ramjetlx]

I know Im supposed to gap my plugs lower when running nitrous but with an MSD box they recommend at least a .55-.60 gap. I drive my car always on the street and the strip on the weekends. Currently the timing is at 10 degrees and the plugs are gapped at .55. Im running a 125 shot now but sometimes switch it to 150. Can anyone recommend what would be the best gap and timing please? And where is the best place to install the spray nozzle on a dry system? I currently have it in the throttle body right before the throttle plate. Any help is greatly appreciated!!!!!

Im running an NX kit with a 150 shot and a 6al ignition. With a plug gap of .045 I had problems with the spark blowing out. I now run my plugs at .030 with no problems and I retard 2 degrees of timing for every 50hp of nitrous. I run 14 degrees base timing on motor and when im on the 150 kick I knock it down to 8 degrees base.

I had the same problem.. gapping them to .030-.035 solved my spark blow out with a 150 shot with the MSD. Good luck
