So what about the plugs that are split in the middle of the electrode, and looks like a snake's tongue, do they add extra power

Or the Bosch series that have two, three, or even four electrodes

 

damn fordman, if you want to run 11's that bad just put a sneaky pete system on...no one will ever know

 

:notworthy: :notworthy:

You've to be fucking kidding me Porsche boy. You don't think there's any power in synthetics but primped up spark plugs are ok in your book? I myself think there may be power in this, but I can't imagine you going for it.[/quot]

Didn't you read my post?

In high compression or high boost motor it will reduce the chance of detonation. It would be useless in a motor that is not pushing the envelope though.

No sharp edges should be anywhere in a high performance combustion chamber.

And fuck those funky plugs. All you need is a small area where you can jump a spark. Split fire and multi-electrode plugs are just adding to the pre-ignition problem.

 

They're BS. Electricity will follow the path of least resistance. By definition, there cannot be two such paths at any given instance of time. The picture of the Splitfires is, how shall we say....an artists conception. There will not be two sparks at the same time. Now, with something like an MSD (multiple spark discharge), on any given firing stroke, there will be multiple sparks but they are sequential, not at the same time. They may follow a different path on the Splitfire...but then those are all individual sparks...not what Splitfire tries to lead you to believe.

There, that didn't make a damn bit of sense, did it?

 

there is 'some' power to be had in prepping your plugs.

The theory behind removing sharp edges is solid. They will build up heat and can lead to detonation.


By cutting back the electrode some, you have less of a shroud around the initial flame cone. Be cause it is less enclosed, it will grow quicker. The fact that combustion spreads across the cylinder more quickly means you'll get a more uniform burn and slightly more power. We're not talking 20hp here. I imagine this could lead to spark blowout in forced induction applications.

Indexing your spark plugs is another thing that yields minute gains. (Setting the sparkplug so that when it is torqued the open side of the cathode is towards the incoming air/fuel mixture/injector)

Now, the splitfire and others like them. Everytime your spark fires, you vaporize a bit of the cathode and a bit of the anode (in the case of platinum plugs this is VERY small). The splitfire and other similar plugs give you more surface area on the cathode, so they will (in theory) provide good performance longer.
