Engine Tech 201: Bottom End | Pistons, Rods, Cranks, Bearings and Sleeves
It’s been said that “You have to start from the bottom, if you want to get to the top.” The same can be said about building a top-performing engine. One needs to start building up the bottom end if they wish to realize top-level performance. Whereas turbochargers, superchargers, camshafts and […]

How To: Five Ways to Build a Bulletproof Engine Block
What is bulletproofing? In terms of high-performance engines, bulletproofing refers to increasing the power handling capacity of an engine beyond the desired power level. Depending on the design of the engine and the magnitude of the power handling increase desired, the bulletproofing process will vary. The parts and processes needed […]

Boost vs. Compression: Benefits of High Boost Levels and High Compression Ratios
One-thousand horsepower, four-cylinder engines are today’s reality in import drag racing. This reality includes the leading-edge forced induction and engine-management technologies that make power production the easy part of building a racecar. Today’s performance engines are running at higher boost pressure levels and higher compression ratios than ever before. Understanding […]

How to Properly Tune your ECU for Power, Efficiency, and Reliability
Before the advent of plug-and-play engine management systems, affordable UEGO sensors, and open-source reflash programs, the number of engine management “tuners” were limited. Before plug-and-play, a stand-alone system required hours for proper installation of the flying-lead harness. The complexity of the install deterred many from learning the skills necessary for […]

Fuel 101: Race Gas, Octane, and Alternative Fuels Explained
What you feed your engine determines it’s ultimate performance. The nutritional performance needs of an engine are influenced by a number of factors. Some of the most important factors include compression ratio, rpm potential and boost pressure (on forced induction applications). Engines that run higher compression ratios (above 10:1), operate […]

Exhaust 101: Moving Up By Moving Out
Turbo exhaust manifolds, headers, downpipes and cat-back exhaust systems are all designed to increase performance by improving the exhaust flow out of the engine. On “all-motor” applications, the proper header and cat-back exhaust can reduce pumping loss, increase scavenging and improve cylinder filling to maximize volumetric efficiency, torque and power. […]
