an impact wrench.... = hammer it... jump on it if you can, or put your foot on it and grab the frame of the car and torque-loose the bolt...
got a friend with an air compressor?
block the trannie/jam the flywheel and slip a 6ft + pipe on the wrench it will help as a breaker bar...

good luck.

I've also heard of people pulling a spark plug & filling the combustion chamber with rope to stop the piston from moving while you're cranking on the bolt.

Never personally tried it, but it sounds like it would work pretty well...

if you can find it there is a tool that pretty much is a vise grip with a chain buit on to it. you lock it onto the crank pully and it holds it in place while you user a breaker bar to loosen it with.

Jam a socket in the flywheel then use a 6 foot pipe on a 2 foot breaker bar. Works for me everytime and I'm far from a muscular guy.

I tried all of the non-power methods, including the 6-foot cheater bar, blocking the wheels, having my girlfriend hold the brake pedal down, and burning incense.
I got my neighbor to bring over his 150 PSI compressor and impact driver, and wwwwwooooden! It was off of there in 2 seconds.
