Tom,
   I think Greg's 1.06 A/R turbine hsg is probably in the bal= lpark..........Your 0.72 hsg (corrected 0.60) 
will probably be a screamer off the ground and for racing but may t= end to have excess back pressure
and over-speed at cruising altitudes............You may have to have an= extra turbine hsg for cruise to
reduce wear on your turbo since your ship will be dual purpose.........= ..........The  current group flying
Turbo/13B's with TO4 turbine sections have 0.98 to 1.15 A/R hsgs.......= ...My TO4E-50 has a 1.15 A/R
hsg for cruising at oxygen levels (12,000 msl +)............Your 20B fl= ows 1/3 again more air than the 13B
and of course all of our projects will take flight testing to prove out= all these guesstimates.........IMHO

Hey Tom= ;
Ours is the 1.06 A/R, and as you can see, we are going straight out the= side of the cowling.
Boost wise, we have a box of springs for the wasteg= ate, and will wait for the dyno tests to find out our best settings.  W= ith the prop configuration we have, we anticipate not a hell of a lot of acc= eleration, until we hit around 120 Knots, and then watch out........(:-)
