R-3350 Radial Engine Run, Test #2
This is the second test run of the famous and rare R-3350 turbo Compound Radial airplane engine. This engine
was originally used on a Howard Hughes owned Lockheed Constellation. After
fixing the propeller pitch issue and sorting out the electrical problems,
we set about running the engine to just below 350 degrees Fahrenheit,
Cylinder Head Temperature to allow the engine to warm-up for an off-idle
engine test. Engine was running rich so we adjusted mixture settings after
4Sale fastest street car ?? 2000 hp 1963 Pontiac LeMans
MORE PICS HERE!!!
NOT MY CAR!!! Just thought it was a cool video.
This beast sports a twin turbo 522cid
big block Chevy that screams out 1250hp on pump gas and a ridiculous 2000hp
on race gas! Ever go 0 to 150mph in 5 seconds -- Butch can. Butch and his
3700lb Pontiac cruise the local streets (with parachute, of course) and run
the quarter in 7 seconds. How many 70 year old men have the nuts to mash
the throttle on 2000hp? Not sure, but Butch sure does. The Pontiac was
transformed into this behemoth at Nelson Supercars.
