Got the DD15 $1000 TC gear box. Output RPM about 6000 so a cog
belt into the nose of the 3 rotor should do it.
Turbine RPM about 60,000.

The 3 rotor emissions crap is layer after layer :)

All I need now is the $1500 turbine.

The gear box and fluid coupling weighs 25 pounds.

Hi Paul,  looks good.  I would replace the stock turbo set up for a single
aircraft sized turbo. It would be lighter and more efficient.  If high egt
is a problem, one of the water injection companies has a controller that
can use egt as an input.  Using bypass air from the turbo which might need
another compression stage to mix with exhaust to lower egt is possible.
More mass flow through the turbines and some of the work would be recovered
by the power turbine.  Will you be at SZP Sun.?

This is not flight hardware. The idea is to minimize the modifications to demonstrate a drop
in BSFC. I'll be using a 4 barrel 750 CFM carb in a pressure box.
