   Fantastic, Paul!  The RX-8 intake P-port is a success!

   Soooo,

   What about go the whole hog and P-port both the intake AND the exhaust
   sides of the RX-8 engine?

   I can hear your fingers tapping the keys now: " . . . even MORE power,
   idles better, lower EGT . . . what's not to like?"

   Les Nordman :-)

   I am speechless. Perhaps somebody else can explain it to Les :)

Les obviously already knows the answer...  cause then you have just
returned to essentially the 13B p-port.    Progress in regression  :-)

Hi Dave,

Merry Christmas.

How's it going? How's the new baby?

When do I get to get some pictures of your new cooling arrangement?:-)
