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 take our humble Chevy 350ci project engine Blown Budget back to the engine dyno and subject it to a roller cam conversion and a FAST fuel-injection system for a streetable 500 lb-ft of torque!

This parent torque curve simply sets the highest performance of a particular engine and could have about 20 subsequent versions that are programmed to max-out at lesser figures. These help to make ...

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 ...
