Hmm this is the calc I just tried with abdc of 49*
http://www.kb-silvolite.com/calc.php?action=comp
They ask for .050 numbers +15deg. (49+15) on the in. close. I forgot to mention -2cc pistons but patrick assumed that I guess with 11.3 static.
This nets me 9.12 dcr Every online calc I try comes up with different numbers it seems.
