Yeah, it is truly amazing what can be achieved with engines. I was at a tractor pull contest in Durant, OK in 1977, and in the "unlimited" class there were all sorts of totally unbelievable rigs on display, taking their turns pulling that sled down the arena. Huge diesel tank engines with dual turbos, one guy with an Allison radial fighter plane enginre, and everything else.
The big winner? An Allis-Chalmers farm tractor with a completely hand built, polished, ported, balanced, totally tweaked Chevy 327 that turned an unbelievable 32,000 rpm. Straight pipes on that beast, and he burned through about 5 gallons of Av-gas high octane fuel in about 45 seconds, in the process of dragging the weight sled 62 feet further than anyone else that day. I've stood beside jet aircraft spooling their engines up to full power - that thing was MUCH louder. The only manmade event I've ever experienced that was louder was the launch of Apollo 14, on Jan 31, 1971.
