Hi! Klaus probably has more like about 125hp at the rated 2750 rpm and
sea-level, and turns only around or slightly above 3000 rpm in a race
at Reno's 7000' density altitude. His forte is that he's reduced his
EZE's drag incredibly!
I recently tested my Lancair 235 with an O-235 at 210 mph TAS at 4500'
dalt, 2910 rpm.I typically cruise 198 mph TAS at 2750 rpm at 14,500
dalt, 5.8 gph.
Jim Patillo's Q200 will do about 200 mph at 5000' dalt at 3000 rpm. I
tested his plane at the Livermore Quickie fly-in this past summer with
my three-blade prop, and NO spinner. He did 189 mph TAS at 5300' dalt,
2550 rpm. Correcting his TAS for my spinner on-spinner off ratio-test
in my Lancair, and estimating what his results would be with a similar
efficiency prop turning 3000 rpm yields 203 mph TAS. A well-built
Quickie with a good prop is a good machine!
