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
The Science Behind Wet Sump Oil Pumps & Oiling System Upgrades
All automotive internal combustion engines are equipped with some type of pressurized oiling system. Oil lubrication is essential for reducing friction, preventing wear and cooling vital engine components. Pumping oil to the main and rod bearings creates a friction-reducing hydrodynamic film between the bearings and crank that allows the crank to spin with minimal friction.
V-Twin Validation – How a Harley Discussion Changed an Engine Builder’s Fortunes
What we will be covering here is a general overview of the most common practices and procedures we use in servicing and rebuilding Harley-Davidson engines and things that are unique to V-twin.
Engine Bearing Technology – The Spin on Spun Bearings
One of the worst failures that can occur inside an engine is a spun bearing. It can happen in a stock engine, race engine, gasoline engine or diesel engine. A spun bearing is bad news because it usually seizes itself around the crankshaft journal. What happens next depends on the bearing’s location.

Understanding the Evolution of Cylinder Head Seat and Guide Machines
Do you remember the many generations of three-angle seat cutters and what we used to get by with? Grinding seats is still needed, but just 10 years ago we were grinding 80 percent of the seats. Though we still grind when necessary, today we cut 90 percent of the seats in the heads.
Pro Touring Engine Update
Pro Touring is the niche of niches in the performance world today. And why not, as it’s pretty much anything goes with these truly unique machines. The fundamental theory behind them is to take a car that is not historically significant and update the handling and performance with today’s seemingly endless supply of modernized parts and assemblies.
Engine Bearings – Main and Rod
The bearings that support the crankshaft play a critical role in handling the power the engine produces as well as engine durability. Because of this, bearing selection, fit and installation can make or break your engine build.

Engine Bearings Under Pressure
Today’s hi-flow, aftermarket, CNC-ported cylinder heads, high lift killer cams and induction system power adders (blowers, turbos and nitrous) are making more power than ever before, and really hammering the bottom end of the engine. If the bearings can’t take it, the engine won’t last.
Oiling Systems for Grassroots Racing
Priority one when choosing an oiling system for any type of racing (grassroots or professional) is to establish what the rules allow and prohibit. Somebody has to read the rule book. Whether that’s you or your customer it doesn’t matter. The oiling system has to fit within the framework of the rule book. Period.
