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?
