A 3/4 can get 1000. You would have to go bigger to get 1400 and you would have a hard time holding it and it takes a LOT of high pressure air to run it, maybe more than a home compressor can generate.

But the impact will help to break things if they are going to break, problem is you have to keep recharging the tank to keep the pressure high enough to get full power.

With a 3 ft cheater a 200lb guy can sit on it for 600 ft-lbs, and you can easily pull 300-400 with your arms (times 3), especially if you jerk it.

Every time I had one stuck, the 1/2 impact NEVER worked and I had to use a regular breaker bar each time and it worked.

A torque multiplier makes easy work of things, never used one myself, you have to secure it to something so I am not sure how you would attach it to the wheel. Some front engine nuts have a 350 ft-lb spec (lug nuts DO NOT!) and you need a multiplier, mainly due to space limitations.
