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.

Subject: [FlyRotary] bracket for 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
