How do centrifugal superchargers work?

Your car arrives from the factory. Bolted under the hood is an engine that makes modest power, and it does so by breathing just fine on its own. It could make more power though and that extra motivation could easily come by way of a bit of forced induction. It's time to supercharge your ride.

Which is better: a supercharger or turbocharger?

There are two relatively simple options to boost (pun intended) horsepower in a vehicle: superchargers and turbochargers. But, which is better? Once again, Jason Fenske of Engineering Explained is here with an answer. It's important to understand how both options function first. A turbocharger relies on a vehicle's exhaust to spool up a turbine to power a...

Why can some engines rev to 9,000 rpm?

You blip the throttle and your engine revs rise. It's a fun game that can put a smile on your face as you wait for a red light to change to green. It doesn't matter if it's a lumbering diesel in a pickup or a muscular V-8 in a pony car, you're likely to crack a smile when you tap that throttle. In some cars, you might just find a maniacal Joker-esque smile...

What exactly is the difference between horsepower and torque?

There's a battle of words that occurs when a group of people begin arguing over who has the fastest machine. All sorts of performance metrics are thrown around, and it can quickly become a miasma of uninformed soup. Some think they're going to win a race because they have more horsepower, while others scream from the hilltops that torque is king. What's the...

Why do electric cars usually have only 1 gear?

You won't jump into a modern electric car and row through a number of gears as you race down the road, which begs the question: why is it that electric cars usually have only one gear? It's but another topic for Jason Fenske of Engineering Explained to cover for us, so throw on your learning caps. Foremost, the broad answer to the question is that electric...
