4.7m lbs thrust divided by 3.1 m lbs rocket = 1.51 Thrust/Weight ratio for FH
7.8m lbs thrust divided by 5 m lbs rocket = 1.56 T/W ratio for Saturn V
Pretty similar... Should look about the same.
1.7m lbs thrust / 1.2 m lbs rocket = 1.41 T/W ratio for Falcon 9 currently flying
If anything, FH should have a little more "giddy-up-go" than the current Falcon 9...
6.78m lbs thrust / 4.47 m lbs rocket = 1.51 T/W for shuttle
Same as Falcon Heavy, so the liftoff should be about the same.
