Information is rather hard to find.
A recent report from the ACSM puts the figure at 4-11% for blood doping taken alone.

That study seems to be based 10 or so studies of the subject.
I also found a 1991 study (abstracts) by Ekblom and Berglund saying that for equivalent results in terms of increased Hct, blood transfusion (fast acting) and RhEPO injections (6weeks total) give the same gain in VO2 max. In that case an increase of Hct from 44% to 49.7% gave an 8% increase in VO2max.
Most relevant articles on the subject are impossible to access for free.
Please help me gather more information
