Over time, in this column, we have touched upon several aspects of not only how to achieve higher levels of volumetric efficiency (as it relates to torque) but the importance of this feature in a ...

But I wasn't saying that the torque curve between a high revving engine was the same as that of a low revving one, but merely that all torque curves are basically the same overall shape (there's going ...

Engine power is a product of its overall displacement, but two similarly-sized engines with different bore and stroke ...

Dynamometer tests are used to measure a car's torque and rpm response. But how do they get that information? And how reliable is what they get?

The Honda S2000, the Mazda RX-8, the Ferrari 458, the Porsche GT3. What all of these cars have in common is that in stock form they'll rev all the way to 9,000 RPM, if not faster. But what allows for ...
