   I am waiting on a cl= arification  from "Turbonetics" as to what size turbine wheel

  Perhaps I am being anal about this but and you are pr= obably correct that that the

effect of a 3mm diameter&nb= sp;difference between the two turbine wheels is slight and

like to shine some light on this please jump in here != !..........

  On another note do you = happen to have any photos of your 13B/turbo installation

I do not know which wheel is in my t= urbo.  I expect the larger wheel (68 mm) to turn a little= more slowly, since it has a larger surface area to absorb the exhaust, but= it should not make much difference.  Either one should b= e OK.  The Turbonetics people can probably explain the pe= rformance differences between the two wheel sizes.

= I limit my takeoff power to no more than 42 =E2=80=9C o= f manifold pressure (=E2=80=9CMP=E2=80=9D), usually just 40=E2=80=9D= .  At altitudes of 5,000 feet and above, I generally run no more than= about 36 =E2=80=9C MP (15 GPH) and 180 knots.  Engine RPM is about 5,= 800.  The turbo is capable of considerably more boost than this, but I= have to watch engine water and oil temps at higher power settings.  I= do not want to run more than 200 degrees on oil or water and prefer 180 de= grees.  I can maintain these temps (even on hot days) with cowl flap s= ettings from closed to full open as long as I keep the power settings at or= below those described above.  One day, I climbed to 11,000 feet and m= y GPS groundspeed (with a slight tailwind) was 213 knots.  MP was 36= =E2=80=9D, RPM 6,000.  I have a 68=E2=80=9D diameter x 84 pitch Prince P-tip fixed pitch prop coupled to the RWS 2.17/1 reduction unit.
