1945(1192) A Germania Superior ADA developed the hyperinsurpulsor. it is similar in purpose to the fistinsurpulsor developed in 1925, however it instead uses the engine's exhaust fumes for power. This frees up RPM and greatly increases volumetric efficiency, but lags for start up and reaches temperatures as high as 1400G (700C). As engines have long been commonly laterally mounted, the installation of fistinsurpulsors and hyperinsurpulsors do not look as odd as their OTL equivalents. 1956(1203) A telelexy cable was crossed through the Parthian gulf from Mazun and continued into Bactria.
