Yes the Juka has a M-14P. I highly doubt that Sean Tucker has a O-520 in his plane because Lycoming never did make a 520 ( to the best of my knowlege, some of you older fellows can probably prove me wrong, I'm only 16), only Continental. I agree with Rossan about not getting 400 hp out of an IO-540, because Kirby Chambliss more horsepower out of a -540 that was putting out 260 to begin with. I don't think you could get 100 or even 140 hp (if you had a -540 that put out 260 hp) without compromising reliability and safety, or without ending up building a brand new engine. But what do I know ?

Rossan, what year was your Laser? I know this is somewhat random, but since I am a pack rat with aviation magazines, I kept an issue of Aero Trader from a couple years ago that had a big picture of a Laser with 230 hp. Did you ever compete with it? I have a friend that is going to check me out in his CAP 10B, which might become a 10C in the future. I am really looking foreward to that!!
