.  I ran the Sun 100 race at very lean

condition, only 1 bar flashing on the mixture monitor.

I'm curious - why?  When in a race, wouldn't you want to run near max
power?

Haven't you heard of sand bagging Al?   : )   Gotta save something for next
year's race in case those Lyc drivers come back with more power.
At best power mixture my engine will burn 20 GPH.  I leaned it to 16 GPH
initially (off bottom of mixture monitor scale) but gradually richened it to
17 GPH as my "race tape" started peeling off and created drag.

On the subject of my engine configuration,  the side housings are 2nd gen 4
port turbos with only a slight port cleanup.   Ports were raised about .1"
(closing later) which is less than a mild street port engine.  I found it
very interesting that the RX8 engine does not open the secondary port barrel
valves until the engine reaches 6250 rpm.   Radical port timing may not be
the right thing to do at 6250 or less.
