thanks thor and nhayman. yes, its the conventional single spraybar. well actually you can't see the spraybar like the old spraybar type nx plates. the holes are integral in the center area on the plate, i assume this is a new plate design.
nhayman what type of fuel pressure are you using on your 100-150 shot? are you flowing your fuel system? also, how much timing are you pulling? is your motor mainly setup for n/a or built for nitrous? your car runs great.
