Camshaft Selection
“What camshaft should I use?” How many times have you been asked or heard that question uttered? Why is it so difficult to choose the “correct” camshaft for an engine build? What separates one camshaft design from the other? After all, isn’t it true that a camshaft opens and closes valves? Simple, right? Well let’s
Round and Round – Valve Timing Events and the Order of Importance
If you’ll recall, in the January issue, we got into the nitty gritty details of what makes a camshaft the “right” camshaft. In this issue, we’ll continue the education. Cam class is back in session! Remember the camshaft makes one complete revolution (360°) while the crankshaft rotates twice (720°) for a complete engine cycle. Camshaft
Camshaft Class is Back in Session
A theory prevails in which a cam lobe that opens to maximum lift and closes instantaneously is quintessential for maximum power and torque operation. Two problems exist with this premise. First, it’s highly impractical due to current technology. Second, this theory discounts a fundamental dilemma that air has momentum, and this must be utilized to achieve
Turbochargers: Boost Your Turbo IQ
In the past decade, turbochargers have found their way onto more engines in cars and light trucks than ever before. By 2021, predictions by some experts cite turbocharged vehicles will reach up to 38 percent of all new vehicles sold in the U.S. Once thought of as only a means to increase performance on exotic

There’s No Simple Formula to Choosing the Perfect Camshaft
The camshaft design affects valve timing, compression and the engine’s ability to breathe. From pistons to manifolds, valve grind, piston pin offset, rod length, etc. Once the camshaft has been tabbed correctly for the application, the rest of the build can focus off that selection.
