I've always done it on an engine stand with the flywheel locked, but how about putting it in reverse and backing it up to a solid wall with a moving blanket and an old tire to pad the rear bumper? You ought to be able to get 160 ft lbs before the car went through the wall or caved in! Never done it, but under the shade tree, there's always a way! Happy New Year, everyone!
