Ben:
It should get a fuel flow of about 30 gph at full throttle with a MP
of about 32 to 34.
If you are around on Friday, come over to the west side and you can
see an engine run for yourself!
Thanks.

My mistake was thinking the 360 was naturally aspirated and the 400 was
supercharged. I now see that both are supercharged and the 400 charger i
s slightly overdriven for more boost. What confused me was in the origin
al post it said full rpm. I wonder why you didn't get 30" then.. A gear
driven positive displacement blower should put out a given amount of boo
st at a given rpm. I am hoping to fly over Fri to see ya. Call me with
a time... Seeya.
