Rick Titsworth asked: Do you know the A/R of the Piper Mirage turbos (the A/R is
typically cast into the external turbo
housing/face and will be obvious if you look closely – approx ½" font size) – I believe they are A/R=2.0
(unverified).
My engine just arrived. The Mirage turbo
compressor is P/N 443705-007 and the A/R is .50. The turbine side A/R is
.58.
