Tom,

   I think Greg's 1.06 A/= R turbine hsg is probably in the ballpark..........Your 0.72 hsg (corrected= 0.60) 
=0A
will probably be a screamer off the ground a= nd for racing but may tend to have excess back pressure
=0A
and o= ver-speed at cruising altitudes............You may have to have an extra tu= rbine 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 h= sgs..........My TO4E-50 has a 1.15 A/R
=0A
hsg for cruising at ox= ygen levels (12,000 msl +)............Your 20B flows 1/3 again more air tha= n the 13B

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 wastegate, and will wait for t= he dyno tests to find out our best settings.  With the prop configurat= ion we have, we anticipate not a hell of a lot of acceleration, until we hi= t around 120 Knots, and then watch out........(:-)
