### Engine Displacement Calculator

This calculator determines the displacement of the engine by two methods; selecting the engine to get the geometry of the configuration, or by the geometry to get the engine. You may select the engine manufacturer and designation to get the exact parameters. [Read More…]

### How To Determine Proper Exhaust Tubing Size

This table below was supplied by Flowmaster. It’s intended as a basic reference guide to give you an idea of the general exhaust-pipe size needed to balance the prevention of excessive back-pressure while maintaining adequate exhaust-gas velocity. [Read More…]

### Understand Nitrous Oxide Systems (NOS)

Fitting a nitrous kit is definitely the way to go for an instant boost in power. If you’re like us, you’ve probably watched all the installments of the Fast and the Furious for the cars. Whatever your reasons, those movies immortalized nitrous oxide as the most popular means of boosting a car’s performance. [Read More…]

### Understanding Performance Brakes

Performance brakes are designed to take much more abuse than normal brake components. For this discussion we are limiting ourselves to disc brakes only for the convenience of terminology. Other forms of brakes exist and the same basic principles we will discussed here exist in those systems too. [Read More…]

### Speed Potential Calculator for Ring Gear and Pinion Changes

This calculator is designed to give the potential speed values of a vehicle, based on the RPM of the engine, the ring gear and pinion gear ration, the final transmission gear ration (usually 1.00) and the tire diameter, ground to top of tire as mounted. [Read More…]

### Horsepower Gain from Additional Blower Pressure Calculator

Enter the anticipated blower pressure. Enter the normally aspirated horsepower at the flywheel or transmission. Click on Calculate. The value will be returned in estimated horsepower, based on blown pressure increase. [Read More…]

### Understanding Aluminum Heads and Spark Plugs

Spark Plug seizure in an aluminum cylinder head is usually caused by improper installation and too much torque. Aluminum alloys are softer than cast iron. Different plug shell and head materials cause these metals to expand and contract at different rates. [Read More…]

### How To Calculate Size of Carburetor Needed in CFM
