plug gapping w/ digital 6blackbird007 10-05-2002, 08:21 PM I have the nx wet kit (100-150shot). It has all the safety stuff and I have ngk-tr6 plugs that I need to install. I just bought the msd digital 6 ignition and a new msd coil. My question is what should I gap the tr6 plugs at? Someone told me if I had stock ignition to gap at .035, but if I had an aftermarket ignition to gap at .040. Please help me on this one b/c I have no idea. Z28ROC 10-06-2002, 12:03 PM I have mine gapped at .038. But honestly, you won't notice any difference between .035 and .040. So anywhere in that range will be fine on the juice or N/A. blackbird007 10-06-2002, 05:06 PM I dont understand this whole gapping thing. Can somebody please explain it to me? And can somebody tell me what the best gap is for nitrous? dabear95 10-06-2002, 08:17 PM Check out this (http://www.nightrider.com/biketech/tech_spark_plug_gap.htm) article. It should have everything you need to know... blackbird007 10-07-2002, 01:04 AM according to the article my gap w/ 100 shot should range from .044 - .047. But what I want to know is what would be the advantage of using .044 over .047 and vice versa. gb95zconv 10-07-2002, 03:43 PM .038 works well for me.... blackbird007 10-09-2002, 07:29 PM ttt blackbird007 10-10-2002, 07:32 PM anybody dabear95 10-11-2002, 12:56 PM From that article, "Insufficient spark plug gap can cause pre-ignition, detonation, even engine damage. Too much gap can result in a higher rate of misfires, noticeable loss of power, plug fouling, and poor economy." But I think anywhere in the .035-.040 range and you will be fine on and off the juice. Just remember that the gap will enlarge with time and usage. Injuneer 10-11-2002, 01:10 PM I ran the NOS 5176-EO kit with NGK TR6's, gapped to 0.040", with the MSD-6A and had no problems. Currently running a 275 shot, cold Champion race plugs (684/S57YC) at 0.035", and fired by 8 individual LS1 coils. That setup was selected by the shop that tuned the motor, and so far no problems. | ||
