Yesterday's QOTD was a really good one for multiple reasons. One of the many topics discussed was power vs. torque, a concept still not that well understood by petrolheads. To radically simplify the ...

The equation tells us that at 3,000 rpm it would produce 228 hp. But if the engine made 400 lb-ft at 6,000 rpm, it would produce 457 hp. It's true that doubling the torque output to 800 lb-ft at 3,000 ...

The HT383 has been available for a number of years now, and it's an excellent repower option for you GM (on non-GM) truck or 4x4 thanks to its rated 325 hp at 4,500 rpm and 415 lb-ft of torque at ...

The modern era of mass-market affordable turbocharging began in the 1990s with the arrival of VW and Audi's 1.8 Turbo and 2.7 Twin-Turbo engines. For the first time, manufacturers were talking about ...

torque is a force. horsepower is the rate at which the engine does work. Really, all the engine's peak torque, and the RPM at which it produces it tells you is the general operating characteristics of ...

Frankly, you'd think this subject would have been exhausted by now. After all, how much "borderless education" can you absorb about such common and oft-explained engine functions as getting rid of ...

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 ...

The highest torque diesel engines ever made have turned up in everything from small commercial vehicles to powerful locomotives to mining equipment and more.
