Bobby,
I didn’t catch what you mean by,” now I can ground run 36" MP at 6800-6900 rpm with the prop set
for high rpm. I can run 7500 rpm at 31-32".”.
You are running a higher rpm with a lower pressure? Typo??
Did you mean high pitch?
What kind of prop are you running? Sounds electric inflight
adjustable. IVO?? Or big bucks MT? What diameter and number
of blades?

Bill,
Not much data yet. Right now I can ground
run 36" MP at 6800-6900 rpm with the prop set for high rpm. I can run 7500
rpm at 31-32". I have not been able to test the full range of rpm, MP and
prop setting combinations. The attachment shows extrapolated data that
should be in the ball park. I will need to identify max MP at each rpm point
and also fuel flow once fine tuned. I may have excess airflow to my coolers and
could possibly add an intercooler down the road.

Is that your supercharger, Bobby?
Do you have any more pictures and information?

Kevin,
I don't remember anything different about
the lower bolt. My bolts appear to be the same based on this photo.

psru
the self-fabricated bracket that accepts
one bolt from the psru mounting plate attaches to the block in 2 places.
on my 2004 renesis, the upper takes a 8mm bolt. the bottom isn't an 8 nor
a 10mm. the specialty hardware store doesn't carry 9mm bolts. is
that what it is? by chance I noticed that a 3/8" (if I'm remembering
correctly) course thread bolt seemed to fit amazingly well. what
actually goes there? kevin
