I know it is against the rules but this is a me too reply. I was never
disappointed in the performance of N357CJ. Out of the gate I was getting 172
mph at 2500' true airspeed at 3180 rpmr there about. Prop changes gap clean ups
and a few minor things the first year yeilded 178 mph true. over the next 8
years or so I manged to improve to 182 mph true. I thought that i had hit a
wall and did not work very much at anymore clean up. 2 years ago I pulled the
engine to get to the oil leak i had and tore down to refresh, I tuned up
refinished the prop added plenums and did a real fair tune up and carb set up.
Faired a few more things and details and ran speed tests last spring on a very
close to standard day. I was acctually very surprised (and satisfied) I was
able to repeatedly acheive 191 to 195 true mph at 2500'and rpm had increased to
3360. So granted RPM accounts for some increase but so does a bunch of
incrmental increases in efficiency.
Currently I am in a slow restoration of the body work on the plane and
likely to repaint next winter. Maybe a little better then or maybe not Im still
happy as can be with my KR. The potential is high if the work is put into it.
My trip to SNF last week while a bit on the stressful side was well over
2000 miles round trip, an average of 4.5 gl/hr, roughly 160 mph true mostly at
2950 rpm. Climbs to 14,000 and long cruze at 13,500. total of about 13. hours.
Build them and fly the crap outta them

Subject: Re: KR> Speed, HP or drag reduction?
Mike's answer here is the first to really hint at the solution for speed.
Horsepower is great for climb, but if you want to go fast, work on drag
reduction. If you want to go even faster, work on weight reduction.
