Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when ...

But, to both our surprise and relief, the little-engine-that-could held its own quite honorably in yet another series of dyno floggings and cracked 500 lb-ft of torque in the process.

We ignored horsepower and went for big torque with this Dart 450ci Small-Block engine build. Find all the details inside Hot Rod Magazine.

Most electric cars aren't normally associated with performance, but they are able to achieve something gasoline-powered cars can't: peak torque at zero rpm. It's thrown around often, and many will ...

All motors make power in two ways: Horsepower, and torque. Horsepower is a measure of how much work a motor can do, while torque is a measure of the motor’s twisting (or rotational) force.

While an extra 70 hp (or more) is certainly desirable to improve ¼-mile times, even significant gains that come at 6,500 rpm are of useful to a daily driven truck.

That also means you'll likely prefer a diesel engine. Compared to their gasoline-swilling counterparts, diesel engines are the torque kings. Why is that?

Learn how you can reach the highest level of power with proper race engine component selection. - Circle Track Magazine ...

Cummins has put together an upgraded version of its 6.7-liter engine turbo diesel for RAM trucks - here's how much power this new powerplant can produce.

After driving 500 miles, something wonderful happens to new Chevrolet Corvettes. The engine’s torque — key to blazing fast starts — increases about 30%, the car gets faster and the V8 engine ...
