Group,
Being a pack rat and Rotary freak I never throw
anything about our favorite engine.........In my
never ceasing endevor to get organized I refound the attached 13B dyno
sheets sent to me by
Bill Jongbloed in the late 1980's when he was developing the 13B and a prop
reduction unit for
sale..........I guess the effort did not make it as I have not heard of any
Jongbloed engines ever
flying..........
The first sheet tells a little of Bill's opinions on
engines and power in general then 13B's in
particular.............The 2nd sheet is an aircraft
version turbocharged 13B.............Note the power
at modest boost levels............Max corrected 202.7 hp at 6500
rpm and 8.93 in/merc (4.39 psi)
boost..........The 3rd sheet is a IMSA racing 13B (naturally aspirated)
built to last only "6" hours
developing 327.9 hp at 9250 rpm..............I have scanned them to
my computer but each is 700
to 1000 kb and so far I am not computer savy enough to reduce
size............Will send them to
anyone interested..............FWIW
