I think you could easily get the 220 you are after using a 140 HP or so Corvair like Mark L. is using or even a souped up O-200. Build it light and you could be a serious contender for the Pazmany efficiency contest or any other race that will class you with other planes of the same engine size.
I suggest getting a copy of Kent Paser's "Speed With Economy" and doing some work on drag cleanup, exhaust mods, etc. As far as filling the fusalage sides, one of my previous KRs had the sides filled and glassed on the inside back to just behind the seat. Probably didn't add more than two pounds and really made a difference in sound and heat insulation. I highly recommend it. The bottom of the fusalage had plywood all the way back to the forward spar and doesn't need anything else except the foam in the void spaces. I wouldn't worry about doing anything under or behind the seat. Here is a snipet from the archives. -----Original Message----- From: [email protected] [mailto:[email protected]]On I spoke to Troy just yesterday. He told me his cruise speed is about 185-190 Knots, yes, Knots. He also said he will be at this years gathering.
