Nascar also uses the Thunder Gun. It is a powerful tool—a ½-inch impact wrench that uses 110 psi of nitrogen to produce roughly 1000 lb-ft of torque and 15,000 rpm. (A typical impact wrench runs at about 1800 rpm.) You can use a normal impact gun ang get yourself a torque bar at 140ft.lbs. Once it torques out, Grab a torque wrench and see if it's at 140ft lbs. Or go slow old way.
