Are the original Allison/Rolls 250 engine a thing anymore? It was revolutionary for its time - under 400 lbs, 300-400 shp, 30 gph. But now easily below par performance wise.

Edit - supplanted by the 300 SHP Rolls-Royce RR300 and used in the R66.

And so it is! Interesting. The RR info graph smacks of someone who formerly worked at GE. My first week at GE was "Technical & Engineering Leader Boot Camp" held on the Campus of Indiana University where we learned the "GE Way" of visual style, technical reports, financial statements, and PowerPoint standards. Compiling these type of info graphics was a class in itself.
