Horsepower and torque are all about cylinder pressure. Compression ratio, cam timing, cylinder head flow, and all the rest of the goodies that go into an engine aren't worth much if what enters the ...

Some Enginology columns ago, we spoke about the functionality and benefits derived from in-cylinder pressure measurement in increments of crankshaft angles. In that discussion, we noted several useful ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

Many people mistakenly believe a gas cylinder can be used indefinitely, but in reality, cylinders do expire. Over time, the steel can weaken, corrode, or suffer damage from pressure, heat, or ...

Horsepower: 2,500. Cubic inches: 430. Boost pressure: 45 psi. Cylinder pressure: Absolutely ridiculous. Running 6.80s at nearly 210 mph, today’s 275 drag radial door-slammers incinerate the ...
