Plug Gap w/N2O
I have been reading that the plugs needed to be gapped in between .025 and .035. SO I checked mine this morning and put all of them at .030. What is everyone else running?

I run .035 even with a msd 6A. You don't want to extinguish the spark. The little lost power and economy isn't worth the risk. It also depends on how much nitrous you are using. Do you have a spark amplifier? I also have never used any of the exotic plugs. (platinum) I don't even know why, but have heard they don't last with the juice.

I have my plugs at .030, Could you explain what a spark amplifier is. I am still using the opti and gm wires. I am also running the NGK TR55, they are two heat ranges colder. My shot is a 125hp.

Re: (BlackonBlack)
This is a brief discription. Most of the big named ignitions like crane, MSD, Mallory, use a spark amplifier. They increase the amount of spark energy (usually rated in joules) that jumps the spark gap. They can also increase the amount of time (in crankshaft degrees) that the spark lasts. In MSD's case they have multiple sparks per power stroke. This way if the spark or flame front "blows out" it will get re-ignited. Basically you are trying to ingnite the combustion mixture as quickly as possible. It doesn't seem like it, but the amount of time it takes to burn all the mixture has an effect on power and economy.
