A lot of factors go into that 120 hours. Life expectancy of the pilot/aircraft. Also, I would guess, those 120 hours were a hard 120. High performance comes with penalties. (Look at the shape I'm in LOL) I wonder how that punched out Jag engine would fair? Brit products have style,and innovation, Not all that familiar, but is longevity also in the list?
Hey frenchyd. I saw on e-bay, a 4.2 Jaguar powered tank. Now there's an idea for you. Don't know how to link it.
In reply to Dirtydog :to be fair the engines in the B 29 the the Rolls Royce engine escorted seldom got to 50 hours.
Properly maintained the Jaguar V 12 is good for well over 250,000 miles. ( and then can easily be rebuilt back to original since the iron liners just slide in and out)
the reason they don't get that far is because of the owners. They tend to be purchased by older rich guys who are likely not to follow the owners manual. Then they are sold to rich guy wanna-be's more concerned with image than anything. They finally wind up in the hands of the young and foolish.
In reply to Dirtydog : I've seen them they were made of Aluminum (tanks not engine)
During WW 2 Rolls Royce Merlin V12's powered British tanks near the end of the war
