I am installing a 12A in a Q-200.  I started this project, believe it

or

not, in 1981, but for many reasons have not gotten back on it until

now.

I would appreciate any information you have and would like to receive
the newsletter.  My engine was put together by a race driver/engine
builder named Jay (I think his last name was Evison) in Tucson, AZ

with

a company named "RX for Your 7".  It is ported, with low compression
rotors, and race quality bearings/oil pump.  I am turbo charging and
using throttle body fuel injection.  The engine is indexed 90 degrees
with the oil pan on the side.

Welcome to the list Larry.
You are looking at close to 350 pounds firewall forward for the 12A
turbo.
Can the Q-200 take that? That will also be about 150 pounds out of your
payload not counting the necessary balance weight in the tail. An O-200
weighs about 200
pounds firewall forward. Bare O-200 weights are down around 160 pounds.
 Are the wheels still out on the ends of the wings? I would at least
fore go
the turbo and consider it a single place airplane.

RE the weight, I have slimmed down the weight use of an all aluminum
water pump, light weight starter, and some other refinements.  The
airframe has been beefed up the canard and other structures to offset
some the weight problem.  The radiator and oil cooler are on the belly
aft of the cockpit a-la P-51.  I hear you on the single place and will
approach testing very carefully.  There are Q-200s, which have a tougher
canard than the original Q-2, with 0-235's on them with a wet engine
weight of nearly 300 lbs.  The turbo charger is already designed in and
I would opt to change to another engine rather than forgo the lost
performance at altitude without the turbo.
