George,
The valve springs checked around 145lbs at seat height and 375/370lbs int/exh at the over the nose heights (at actual lift) this March and I've only got 4hrs on them since then. I have GPS numbers and "lake balance" set for the combinations below. The plates are currently at an 1/8" up, didn't like the "feel" of the center plate at 3/16" up.
test 1: the 12's and the high rake 11 x 16 (baseline from lake)
test 2: the 18's and the high rake 11 x 16
test 3: the 18's and the round ear 10-7/8 x 16 (with 2 additional nickels)
Depending on the results I may try a borrowed set of 22's. I was unable to find the prop you recommended in a 10-3/4 to borrow. I figured I'd try what I have first and go from there. If you know of a prop I could try PM me with details I'd pay for shipping both ways and discuss what ever else is customary on a deal like that.
Thanks,
Loren
I have a 22p 15.25" diameter 4 blade you can take with you to try. Just let me know... :boxingguy
