Pineapple pic: 4 plugs per rotor?
I followed a link to the pineapple site today, and since I haven't surfed through it in a while I started clicking. I clicked upon a pic that confused me. It was simply titled 13B-REW. If you look though, it seems to have 4 plugs per rotor. The standard leading + trailing, and 2 others drilled in at TDC. Any idea what this would be for? Redundant system for an airplane? They don't appear to travel too far into the housing (look at the plug in the rear housing)

for when you have positively got to burn every last muddaphukkin' molecule of fuel 
rumor has it the tdc plugs are powered not on a capacitive discharge, but the flux-capacitive discharge system. 1.21 gigawatts of spark!

Repost! Someone originally explained the purpose of the 2 extra plugs, just can't remember what they were for.

...they're wasted spark grounds for his 4-coil 8-terminal ignition setup; not actual firing sparkplugs...
...for those who don't feel like thread jumping but HAVE to know...
...I dig the hugeassed waterpump pulley...

So basically the same could be achieved by just grounding the wasted spark to the block? What we all want to know is there any performance advantage with this? Too me fancy grounds (if that's what these are) are just for bling.

Seriously, Thanks Liquid Anarchy. I didn't see the other post.

read the link. it explains it well on the last page last post. Basically the coils that come with the EMS system being run needs the wasted spark, since you cant put a wasted spark on a rotary like you could on a piston engine, they just ground into the block. There is no way or reason to want to run something like that inless you are running the same ems as them, an electromotive tec.
Rob sure makes a pretty engine though. I like the powdercoating colour.
