I can't believe you're still on this... honestly.

Rear mounted turbos are more laggy and lose efficiency because latent heat in the exhaust dissipates as it travels through the pipe, reducing the overall pressure across the face of the turbine.

I know that's exactly what answer you were looking for, and you're going to pick one word out of that answer to try to prove your point, but trust me, it doesn't. The fundamental working principle behind turbine engines is pressure. How you get that pressure makes zero difference, as long as it's there.
