hotbeek:excellent link thnx!!

With 90 octane 8 lb. is a max, 93 octane
is 10 lb. max. I normaly run 12 lb on 93
but its a little trickey. I use two automatic
timeing retards, one at 3500 because i cruse
at 4000 and the second at 5200 that brings
the timeing to 27 degrees. Actually there is
a third retard that is actuated with the NOS
button that reduces timeing to 21 degrees.
Hope this helps.
