I know everyone says use ngk tr6's. But I need to know how this was determined. It's that dang curiousity thing...
How can I find out more?
What happens if you run the stock plugs? Do they misfire? Do they melt down? Do they ping? I read somewhere that the top electrode (they called it a strap) can get red hot in a few seconds, so they advocated finding something with a smaller "strap" more than running a cooler plug. Since the heat range is more related to the overall plug and center electrode.
I know I should run at least one range colder than stock. But what about plug construction? Copper core is ok, but platinum lasts longer (NA anyway...) and I lean towards low maintenance where possible.
In researching the NGK site, I found they make lots of versions of plugs. Some are designed specifically for power-adders and racing (a v-groove center electrode on one, and a tapered top electrode on another). They even have a platinum version, which is designed for the narrower gap. I'm interested in trying something along these lines.
I don't mind experimenting, but I would like to take advantage of what others before me have already learned, so I don't have to start from scratch. That way I can build on the knowledge that's already out there.
How was the best gap determined? Was this from dyno hp/torque results, or by reading the plugs, or by autotapping for misfires, or taking what worked in other applications, or what...?
Or have we (the v6 board) just found something that works, and so that's just the doctrine that we all follow?
p.s. My spur-of-the-moment 5175 is scheduled to be delivered today... So that's why I'm interested all of a sudden.
p.p.s. Although the car will be nitrous only at the moment, plug selection should take into consideration that I will have a blower too, in a month or so (if all goes well...)
p.p.p.s. I'd like to keep the topic focused on plugs only, and NOT get off into coils, wires, cd/multiple spark, etc. for now.
