 Paul,
 If you or Jeff still have any RX-8 coil
 heat sinks on hand, I need one. Just
 let me know how much and where
 to send the money. Thanks.

 I only made one Frank. Jeff never made any to my knowledge.
 Alex Moltena owns it. The demand is not much so far.
 Might take awhile for most people to realize it is the best way to go :)

 If you know someone with a mill you can get the islands
 machined and clamps made. If not my next door neighbor will do it
 for $35 an hour. Drop ship the extrusion to me.

 The minimum order for the extrusion is enough for two parts as I recall.

 Would a spreadable thermally conductive compound be beneficial for this
application?  The product in mind is used
 between the CPU of a computer and it's heatsink.  If it is of benefit,
would applying it to the stock mounting plate
 provide meaningful results?

 That is a given but you still need the islands.
 The thing to constantly keep in mind is four cycle piston engines
 work the coil half as hard.

Found a great heat sink riding the back of the processor in an old HP
computer.  Easy to get to, and free, or nearly so,
when your PC dies.

Lewis.

How big is it. What are the dimensions.

Paul,
I have already contacted the supplier. They are no longer
called M&M Metals, instead they are called Alexandria
Industries. Their minimum order is $250 for a six foot
length, enough for about 12 heat sinks. I can't justify
this for only one part; any suggestions?
Frank

Anybody else need some heat sinks?

There are lots of options.

All of these will work.

You want something about 3 inches wide with fins 1 to 1.5 inches high.
