Of course, that was an engine (Pratt & Whitney R2800) running under steady-state power conditions, so "turbo lag" would have been irrelevant, though you did have to wait for the boost to come up at the beginning of a takeoff roll, as I remember...

Amazing... and it got me searching...
From this site:
http://rwebs.net/avhistory/history/p-47.htm
"The exhaust driven turbine is approximately 22 ft aft of the propeller and is supported by a ring attached to the lower longerons. The exhaust gases are collected by two rings, one each for the left and right bank of cylinders and directed to the nozzle box of the turbine through shrouded exhaust piping along either side of the airplane beneath the fuselage. Spent gas escapes through a stainless steel flight hood which extends below the fuselage."
