Some information you will find here (google translator will do):
[u-historia.com]
There is a book "U-Boat 977 The U-Boat that Escaped to Argentina", by
Heinz Schäffer, where is described a pursuit for a tanker, then it is said:
"All our blowers and compressors are screeching for all they're worth—we keep
on blowing our diving tanks every five minutes, for we have to keep as high
above the water-line as we can, since the higher we are the faster we go.
True, the increase in our speed's only fractional, but it is an increase."
