Engine Machining
Understand what deck height, deck clearance, and quench distance mean, how they interact, why 0.035–0.045 inches is the optimal quench range, and how to calculate the correct piston position for any combination.
Performance
Analyze the famous automotive saying with engineering data. Compare naturally aspirated displacement advantages against turbocharging, direct injection, and lightweight chassis strategies to determine when bigger is better and when it is not.
Performance
Understand the direct mechanical relationship between swept volume, cylinder pressure, crank leverage, and low-RPM torque. Includes BMEP analysis, stroke-vs-bore torque effects, and real-world comparisons across engine families.
Performance
Learn how stroker kits work, what components are included, how much displacement each common stroker combination adds, and what geometry changes (piston speed, rod ratio, compression height) must be addressed during the build.
Performance
Learn how rod-to-stroke ratio influences piston side-loading, dwell time at TDC, bore wear patterns, and engine power delivery. Includes ratio ranges for common engines, the physics of rod angularity, and how to choose the right rod length for a stroker build.
Performance
Understand why a 200 hp Miata feels quicker than a 300 hp SUV, how torque-to-weight and power-to-weight ratios determine acceleration, and how to calculate real-world performance from displacement and vehicle weight.
Performance
Understand how cylinder deactivation reduces fuel consumption by 5-15%, how it works mechanically, which engines use it, and why reducing effective displacement at cruise improves thermodynamic efficiency without sacrificing full-power capability.
Performance
Learn what volumetric efficiency is, why it determines real-world power more than raw displacement, which components affect it most, and how to calculate expected airflow and horsepower from VE percentage.
Everyday Automotive
Understand what cubic centimeters mean for motorcycle engines, how cc relates to power and licensing, what each displacement class feels like to ride, and how to calculate motorcycle displacement from bore and stroke specifications.
Everyday Automotive
Learn how to locate and decode engine block casting numbers for GM, Ford, and Mopar engines. Understand what each digit means, how to determine original displacement from a casting number, and which casting numbers indicate desirable blocks for performance builds.
Everyday Automotive
Learn the 5 most common OBD-II diagnostic codes, why engine displacement determines the expected sensor values for each one, and how knowing your engine's size helps you diagnose misfires, airflow problems, and fueling faults faster.
Everyday Automotive
Learn how to compare mass airflow sensor readings to expected values based on engine displacement, how to calculate theoretical airflow at any RPM, and how MAF data reveals vacuum leaks, dirty sensors, and breathing restrictions.
