Paul,

I recently obtained a Renesis engine by going to Bruce
Torringtin's shop in North Carolina and would like to
install it on my highly modified Variezy which I am
building.  I have Tracy's B model PSRU and recently have
become familiar with your web site.  I noticed Gregg's
mounting/adapter plate and have down loaded your
instructions on designing a mount.  Before I do very much I
was wondering if you have already designed one for a
Variezy.

 We have something similar. I will change it to fit but
 I need the exact dimensions on the firewall hard points
 and the position of the thrust line relative to the
 mount points. Can you scan the firewall dwgs and email
 them to me? If you don't have a scanner you can zerox them
 and mail that to me.

 What kind of intake do you plan to use?

 Please export that as a dxf file Rolland rather than a dwg.

 It is going to be a real challenge getting a two rotor
behind a Vareze... I decided to go with a two rotor for my
Long EZ project knowing that it would be tight but it
wasn't until after I finished rebuilding the firewall and
motor mounts that I had an appreciation for how tight.
Attached are a few pictures of what I went thru to modify
my Long EZ. To make a 13B fit and do it right in "my"
mind, I needed to move the hard points to the outside of
the longerons which required a new firewall and a
modification to the top of the C-Spar for the new upper
hard point location.

It is a lot of work but for me came
out very nice and I think will work great. I'm not really
sure of the width of a Vareze firewall but if it has any
chance of working you would have to do something like what
I did... The Other consideration is structural integrity
of the hard point integration into the structure... Paul
is right about the vareze not being designed for such a
heavy engine but if you go with an aluminum engine and beef
up the Hard Point Structural integration, I think you might
be able to pull it off.

One thing to consider is the
effect a heavier motor will have on your Landing gear... I
solved this by putting Infinity Retractable gear on my Long
EZ... That's another story but one I would not repeat
again if I had a choice. My advice would be to build a
Long EZ if you had a choice but if you could put a P-Port
on a vareze... man would that be a rocket! It would make
a great single seat fun machine.

That is a lot of work. When I built the firewall on thr Limo EZ I used the
Cozy Mk IV layupschedule and did the mount the same way the Cozy does it.
My firewall is 22 " wide and it is still tight. I don't know how you are
going to get the turbo in, Keep sending pics.
