Looks like a fun project! I would shy away from the Kenne Bell supercharger or any twinscrew/roots type. If you lose a belt, you pretty much choke the motor off. If you use a centrifugal, you can at least have a little more partial power by pulling through it, or by using a bypass valve. I also would not rely on a Megasquirt to keep me in the air. Perhaps something more like a Motec or Magnetti Marelli's ecu's. Redundency would be critical here for both fuel and spark. Vesta would definitely be good to talk to.
I hope to start building my Bearhawk someday soon, and would like to use an LS based motor also. Happy Flying!

Don2, I'm curious about your reservations about the Megasquirt...do you know of a weakness in reliability that I haven't heard of? I haven't married myself to anything yet but the use of a LSX engine and chain drive...both because they are about as bulletproof as it gets if set up right.
I won't be using any type of forced induction, at least for a while. The fewer variables the better, and I don't want to go too far from the tried and true until I get some time on the airframe and engine combination.
I've talked to Jason Day, and while his units look good, I can't get him to give me a name of someone using one...or even the amount of time he has in the air. I'm interested in his props, too, but haven't heard of one actually flying for any length of time.
Thanks.

Org,
Nothing in particular. Just the fact that it is a relatively young product that is usually self assembled. I would run one on a car in a heartbeat, but there is potential for way too much to go wrong in an aircraft. I have had my fair share of ECU problems this year with other projects so it makes me a little gun shy about using something like the Megasquirt. I would feel safer flying behind something sealed and proven in professional racing environment.

Luke, http://home.comcast.net/~ogoodwin/Mustang.html is my website, lots of pictures of mine and also pictures of a LS1 installation on another. It's plans built, no kits. I've done all the work so far, but I'm having the landing gear built by a pro...my welding isn't something I want to trust hitting the ground at 70 mph, and there's lots of machine work involved.
Nice site. I lusted after the Stewart S-51 the P51 replica when they were selling them. It's a beautiful but $$$$ plane. My brother is building a "lowly" Zodiac right now. His metal fab work borders on "****" but he's betting his life on his craftsmanship so I can't blame him.
