After printing the "Renesis Engine Power and Torque Curves" that Marc Wiese sent out, I picked torque values from the paper
chart and entered them into a spreadsheet and calculated hp, then added another column for hp values I picked off the chart  for
sanity check - calc hp and picked hp are within half a hp or less.

Now, Marc, can we get any fuel flow info to go with this data?
    -  I assume this chart was made with full throttle (full sea level manifold pressure minus an inch Hg or so for air filter
loss of MAP) so fuel consumption will be somewhat different from what we'd get at 75% of SL pressure inside the manifold after
the throttle body.
    -  i.e., if we wanted to an economy cruise at 120 hp (75% of old 160 hp 13B), we wouldn't go at approx 4300 rpm at full
throttle (from the full throttle chart Marc provided) - rather, we'd be up at some higher rpm at a lower-than-full SL manifold
presssure - maybe 75% of SL pressure in manifold.

Of course, I suspect I'm asking for the impossible (fuel flow info at less than full throttle) because I've never in my life
seen such data from any published dyno run that I've had access to.

In case the attachment gets stripped off, I converted the spreadsheet to webpage document, uploaded to my website but some error
 in the link on home page doesn't bring up the document (spreadsheet) - can't figure it out.

My next step is learn how to create a graph from the spreadsheet.
