Did the first ground
run yesterday with the full cowl on the plane. Ran about 10 minutes and up to
4700 rpm before my fuel pressure went to 9 psi. Out of fuel. The oil and water
temps both came up much faster with the cowl on. Still took about 5 minutes for
oil to reach 140 deg. The oil temp trailed the water by 15 degrees until the
water reached 180. The oil then closed the gap to within 1-2 degrees. Oil
and water stayed at 182-186 for the last couple of minutes before running out of
fuel. Both inlets are 6". Hope they can be reduced once flying. I did have
a 20 mph head wind.
