Is your car hard to push around in and out of the shop? If you car doesn’t roll well, that’s most likely cause there is some sort of bind condition happening somewhere in the drivetrain. Being in bind does nothing but rob power. If it takes more power to turn the wheels, it’s less power getting to the ground. The graph above is from a Street Stock team that had a Monte Carlo that was very hard to push. The driveline was misaligned and the rearend was out of square. Because of this, the car fought itself just to roll. Freeing all the bind up was like finding free horsepower for this team.
