Understanding the Importance of Common Rail Injection to Today
It seems that there have been some improvements in diesel injection technology that have allowed some “clean-up” work on the diesel exhaust system, and I think we all can appreciate the change. Even though some may feel the need to complain about the increased use of electronics and how the government is cracking down by
Camshaft Selection
When it comes to racing, sometimes the belief is that only custom-designed parts are good enough for a winning team. The question here is, do off-the-shelf components automatically have a performance handicap? In order to get to the bottom of the “Custom Grinds vs Catalog Specs” debate Engine Builder magazine reached out to experts at
Dry Sump Oiling Systems
Dry sump oil systems are used on all kinds of racing applications from NASCAR, circle track, road course and Formula One racing to ProStock drag racing. Dry sump oil systems are even found in some current production applications such as the LS9, LS7 and LS3 engines in late model Corvette ZR1, ZO6 and Grand Sport

Team Motive Gear Wins ‘Showdown At SEMA’ Hot Rodders of Tomorrow National Championship
Loara High School Wins Their Third Straight National Championship Title Team MOTIVE GEAR – Loara High School from Anaheim CA. won the 4th Annual "Showdown at SEMA" their third straight, with the average time of 21:24 minutes. The top three teams were so competitive that they all ended up less than a minute apart! All
Three Important Elements Around the Top Corner of a Piston
On forced induction and on nitrous applications, which experience extreme shock loads, Kempf says they move the top ring down from the piston crown to around .300?. However, depending upon valve configuration and the positioning of the valve reliefs, the top ring can be moved down by as much as .450?. But on most small-block
GM Unveils All-New 450 hp Small Block LT1 V8 for 2014 Corvette
The new Corvette LT1 engine, the first of the Gen 5 family of Small Block engines, combines several advanced technologies, including direct injection, Active Fuel Management and continuously variable valve timingto support an advanced combustion system. “Our objective for the development of the all-new LT1 was to raise the bar for performance car engines,” said
Variable Valve Timing Can Help Save V8s, Environment
Not that I don’t supportthe environment and being responsible in our efforts to save the planet– I do. But the passion for the thunder of a throbbing,pavement-pounding V8 is, well, similar to that of the how your heartskips a beat when you think of your first love. What if you could stillhave the power, have
Breakin-In Is Hard To Do
Before we begin discussing assembly lubes and break-in oils, I would like to emphasize that no one factor is responsible for racing success (or failure). It’s like an algebraic equation with a lot of variables, all of which must be addressed. The same is true of engine assembly and break-in. You must utilize only those
Crack Detection and Correction
First off, let’s get one thing perfectly clear – there’s no such thing as “flawless.” Like those shocking tabloid photos of that Hollywood actress who gets blindsided beside a bistro, even the most conscientious engine builder sometimes has to deal with surprising surface imperfections. And just as she has paparazzi to expose the damage and
Performance Piston Rings
When you’re building a performance engine, what kind of piston rings should you use? Rings run the gamut from cast iron to ductile iron to steel, with various dimensions, edge profiles and wear coatings. There are a lot of choices available and a lot of questions to answer. Some piston sets come with rings while
Butterfield, Bubba and Me
Okay, so saying?“I have to play golf when I’m at the PERA?Annual Convention” doesn’t sound like the toughest way to spend an afternoon. But when you’re A; not much of a golfer (me), B; teamed with some industry bigwigs (Peter Butterfield of LKQ, Ken Carter of MAHLE?Clevite and Robert?Yarbrough of Bishop International) and C; expected
Common Rail Injection: Understanding its Importance to Today

Even though some may feel the need to complain about the increased use of electronics and how the government is cracking down by
Getting Your Bearings
Engine bearings have a tough job to do for such a small component. They must support big loads on a thin film of oil (between .0001-.0004? thick) between themselves and the crankshaft journals to prevent metal-to-metal contact. One of the biggest causes of bearing failures is dirt and debris that enters into the oil pan
Takin
Back in the old days, the late ’90s, when the economy was strong and incomes were high, people had a lot more money to put toward their favorite hobby, which for many was a souped up car that could be driven on the street but maybe also a little on the track as well. Today,
Intake Manifold Cleaning Caution (#1)
If piston failure occurs in this engine, it is possible for broken pieces of piston to end up in the intake plenum. This is due to the design of the engine, which has tuned runners with the plenum located below the runners. The piston pieces may be ingested into the engine if they aren’t removed
Debunking the 10 X 10 Crankshaft Myth for Customers (#5)
First of all, in normal use or even high performance use, a used crankshaft will not “clean up” to standard specifications and will usually have to be ground to .010? undersize. The crankshaft has then remained 98+ percent as strong as new. The problem arises when “spinning” or “hammering” (knocking) a bearing. The crank will
