Please do not shave the thickness of the grounding electode on your plugs!!!! There is no need to do this, they will not effect horsepower or torque. They really don't. You want to keep that grounding electrode tip thick and happy, cause it is taking a h e l l o a lot of heat and pressure during your runs.

What I do AGAIN is to bend out the gounding electrode tip in order to gain access. I use a thin cutting wheel or a thin hack saw blade and I cut a vee shape into the tip of the grounding electrode. No as the center electrode fires the spark across the gap it grounds to the electrode but the spark event then "SEES" more of the air fuel mixture that was squeezed into the V that I cut in the tip.

So I am after a better preignition environment. That is why we v cut the grounding electrode tip. Then we run a HOT ignition box with 55-75,000 volts and push that electode gap to .055 or even more if we can get away with it. We want to expose AS MUCH air fuel mixture to the voltage event as humanly possible.

The reason why we use Magneto's on top fuel drag cars is that they produce MORE voltage as the RPM increases, while a distributor typically delivers more voltage at low rpm, and falls off as the rpm increases.

So I would expect that Eric 4 Nitrous is probably using a super box on a distributor, or a Magneto should his rules allow it.

On our racing aircraft engines we use TWO magnetos, so if one fails the other can keep the plane in the air.

Now on NASCAR our Ford guys are running durospark distributors with two reluctors and two hall magnetic triggers stacked one atop another with a switch in the cockpit, so the driver can switch should one trigger fail!

Here is a secret you do not need if you are running the drag strip. But if you autocross or road race, this speed secret is a nice way to finish more races!!!

Hope this helps!

Thanks for all the early and good responses.....

Eric, have you had a cup of coffee yet?????????
