Todays Project - What did you do today?

[rleete]

Okay, so I did this about a week and a half ago.  Took pics, and then promptly forgot about them.

Anyway, take a piece of aluminum (6061?) and turn the O.D. to size:

   
 
Part the pieces off:

   

And you get 4 center drilled discs:

   

Then you bore them out to get 4 shiny rings:

   

Next, do the same sort of thing with some aluminum rod, but drill and tap instead of bore out:

   

Face off the heads of a few bolts:

   

Take a strip of aluminum (painted, sheared to size at work) and drill/bore out a few holes:

   

Put it all together.  Anyone know what it is?  Okay, enough suspense (I know you guys all peeked anyway) so here it is:

   

   

It's a CoP (Coil on Plug) setup for my Miata.  Gives better spark to run more plug gap, for better burn.  More power, better mileage.  Most, if not all newer cars come from the factory this way.  Since my car is a bit older (1994), it's a good, fairly cheap upgrade.  It's also one of the initial steps to forced induction, which will be in the form of an Eaton supercharger, going in later this year.
