I have heard that 115/145 is made up once a year for the Reno Air Races but is
otherwise not available. I just read an article about the C-119 which uses the
same R-3350 engine as the B-29 though I am sure the variants are different.
IIRC the pilot of the C-119 stated that with 100 Low Lead fuel the engine put
out about 2400 HP instead of 3500 but with water injection could put out about
3400.
