SuberAvid gets re-powered (again)

I got the sign-off on 'SuberAvid' in 2010 but it seems like I have never stopped making changes to it.  What a great test bed.  That is one of the greatest things about building your own experimental airplane!  This spring I pulled the Rotax 912 ULS and installed an Edge Performance 912 STi.  For those unfamiliar with this motor, it is a new Rotax 912 that Edge Performance tricks out by welding the crank, installing oil squirters, new pistons, fuel injection, turbo and intercooler, engine management controller, etc. and it ends up about 155 HP.  I also installed a Sensenich 82" ground adjustable prop. 

After quite a bit of on and off of the engine to fit it up, remove old parts, rearranging the firewall layout, fit in new parts, adding some new instruments, building plenums, ducting for the intake air and intercooler, fuel lines, reworking wiring, mounting parts, etc, etc, it finally came together,  Initially the EGT's were too high but it is kind of cool that I was able to connect the supplied tuning cable to my laptop and connect by zoom meeting to the USA dealer,  Michael Busenitz, and he can adjust the fuel rates to each individual fuel injector,  After several sessions of adjusting and flying we were able to get the EGT temps exactly where we wanted them.

I have about 30 hours on it now and needless to say it makes quite a difference and leaves you grinning!

Attached are some of the installation progress and completion pictures.

Wow!  pretty impressive.  Did you build that two piece motor mount?  Bet it really sets you back in the seat.  JImChuk

For the guy who never wanted a Rotax you have come full circle.  Congratulations.  LOL.

I look forward to a comprehensive review of the Edge engine.  (It will probably be my replacement, less the turbo, when the Mangy's Zipper has had enough)

Jim, Leni built the motor mount; It is the same one as used for the carbed 912 I took off it.

Larry, too funny; you are absolutely right.   :).   I will write some more on the engine soon.
