You may ask, why go through all this; speed! With an O-200 in front, the KR
should be able to produce better speed numbers(210-230mph) and not sacrifice
much more in approach and stall speeds.
Unless you intend to go with high compression engine turning 3000+ rpm,
you may find the performance less than expected. With something like
the KR100 you may achieve 175 mph cruise on 5 gph. My KR is a bit heavy,
765 lb.s empty, larger frontal area then most, old RAF48 airfoil, and I
flight plan on 150mph cruise, no wind, at 2450 rpm, burning about 5.2
gph. If I go full throttle, 2800 to 2850rpm, and let it get it's legs,
I'll see the IAS approaching175mph and it's probably higher than that in
That 200mph cruise at altitude on a turbo VW advertised since it's
inception is for most builders a pipe dream. You can't change the law
of physics just by calling it a KR.
Realistic expectations is the best cure for disappointment.
