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.

Yes. after about 9 AM

Found a used Holly 750 CFM carb for $75 in good shape.
I'll get an adjust a jet kit for it.
