In Australia it was common practice particularly in the outback in summertime with temps often up around the low 40's C.
Most times one was using ships battery so Very conscious of not having to abort the start and having the temp needle hovering around the red line.
One tended to use a lot of Water Meth too.
Took off once at Tennant Creek south of Darwin in a Viscount. OAT was ISA +25. Could see the W/M quantity guages dropping during t/o and I'm sure I could hear it gurgling down the pipes!

Hmmm, never operated in temps that warm. We were the other way. Usually performance improves as the OAT gets colder but once you got to an OAT of minus 20 C, performance suddenly dropped off(ie WAT limits). Why.....no more water meth allowed below -20.
