And if it didn't have a blower, it wouldn't get rid of the exhaust gasses either!


That was only on aircraft that were either normally aspirated or Supercharged(engine/gear driven). When they installed turbo-superchargers (exhaust-driven) on them the exhaust (and induction) systems became VERY complicated.

I'll also add that the main advantage of the Merlin was the 2-stage supercharger. it could literally be manually shifted into "high" gear to increase boost for high altitude performance. The exhaust driven turbo-charger essentially replaced the (MUCH less reliable) gear driven supercharger. (except in DDA engines!) I must also say that I don't think there ever was a production turbocharged Merlin. OTOH, The P38 Lockheed lightning) had turbo (super) charged Allison V-1710 engines.

 

At the coal mine where I work there is an old surviving Euclid coal hauler that has been transformed into a cable reeler for the draglines. That beauty has on old 6-71 N/A Jimmy in it. Must have been pulling its guts out lugging a trailer with 20-30 tons of coal up a ramp. Quite a bit smaller than the Kress 180 ton coal haulers with V12 Cummins in them.

The previous mine I worked at had a fleet of 793 Cat OB trucks with 4200cid twin turboed V16s.
