Tesla Roadster Revealed: It Flies, It Kickflips, It Rockets! Right? Math From 6 Years Ago Tesla has unveiled the new Roadster, and in classic Tesla fashion, they have some wild marketing stunts to go along with it.

Porsche's 6-Stroke Engine Is Fascinating – More Power!

967K views · 3mo ago · 1:11

Porsche patented a 6-stroke engine, yes, two more strokes than you’d commonly see for a combustion engine, and most excitingly, one of those additional strokes is a power-stroke! We now have two power strokes per cylinder within the full six-stroke cycle. The way it works is through Porsche’s genius hypocycloidal design which the crankshaft follows. This creates two different stopping heights for the piston at both the top, and the bottom of the cylinder.

4 Problems With Direct Injection Engines

673K views · 5mo ago · 1:17

The single biggest technology change to gasoline combustion engines over the past 50 years is arguably direct fuel injection, and unfortunately, it brought with it problems. In 1975, over 95% of gasoline engines sold in America were carbureted. By the year 2000, nearly 100% of gas engines (99.8%) had made the switch to port injection. And by the year 2025, over 80% of gas engines are now using direct injection, thanks to the power and efficiency benefits.

One. Million. G’s. You simply cannot fathom the g-forces that a turbocharger wheel experiences. Turbo maker BorgWarner tells me their smallest turbo can spin up to 324,000 RPM, with a compressor wheel diameter of 30mm. Some quick math tells us the outer edge of the compressor wheel is traveling at speed of over 500 m/s, or 1100 miles per hour. So, what about g-forces?

Torque doesn’t matter, it’s all about horsepower. Say you have a car with 100 horsepower, but only 1 lb-ft of torque. Then take that same car, but now it has only one horsepower, but 1 BILLION pound-feet of torque. That sounds exciting, but once you learn that horsepower is the rate of doing work, in other words, how quickly you can move something from point A to point B, i.e., how fast a car is, you’ll realize the torque number becomes irrelevant.
