Recent Advancements in Racing Oils
The racing oil community has been very busy this past year. This is much more satisfying to an old “oilhead” who has seen years where there were no new racing oil developments. Racers and engine builders traditionally focus more on improvements in hard parts, because that’s what they understand best. However, recent successes in racing
Diesel Engine Oils: Today and Tomorrow
Why are diesel engine oils different than any other engine oils? The Lubrizol Corporation, the world’s largest oil chemistry supplier, just created an excellent website (www.hddeo.com) that explains diesel engine oil composition very well. Diesel fuel combustion (or incomplete combustion) is accompanied by the production of soot (unburned carbon). Prior to exhaust emissions legislation this
Racing Oils
As a motorhead physicist, I get to look at engine lubrication from theviews of both an oil formulator and an engine failure analysis expert.Since I used nitromethane fuels when I raced funny cars, I’ve seen morethan my share of engine failures. I’ve also formulated oils for usewith alcohol and nitro burning engines, but let’s leave
High Oil Consumption Due to Wrong Air Intake Hose on Some Mazda RX-8 Engines
Affects: 2004-2008 RX-8 It appears that the service part hose for the 2009 RX-8 was shipped for 2004-2008 RX-8 by mistake since January 8, 2008. If the hose for a 2009 model is installed on a 2004-2008 RX-8, the barometric pressure, which is normally applied on a small hose (A) connected to the metering oil
Oiling Systems For Grassroots Racing
One of the first things to look at when building an engine is the oiling system. Dry sump systems are very scalable and efficient but are not known to be inexpensive by any means. Wet sump systems, on the other hand, offer affordability and can handle some impressive performance applications, but using all stock components
Diagnosing Oil Leak on Ford’s 7.3L Super Duty Truck Diesel Engine
Some 1998-2003 E-Series, 1999-2003 Super Duty, 2000-’03 Excursion and2000-’03 F-650/750 vehicles equipped with a 7.3L diesel engine mayexhibit an oil leak at the high-pressure oil pump outlet fittingsand/or end plug. Accordingto Ford, this type of leak may appear to be a rear main crankshaftseal, oil pan gasket or other engine oil leak due to the
Advantages, Myths and Fables of High Volume Oil Pumps
The oil pump’s most difficult task is to supply oil to the connecting rod bearing that is the farthest from the pump. To reach this bearing, the oil travels from three to four feet, turns numerous square corners through small holes in the crankshaft to the rod bearing. The rod bearing doesn’t help matters. It
What’s New with Oil Pumps, Pickups and Pans
The two greatest concerns from a lubrication standpoint are dry starts and loss of oil pressure while the engine is running. Dry starts are more of a worry in engines that have front-mounted oil pumps with relatively long pickup tubes, which includes such popular engines as the GM 3800 V6, Chrysler 3.5L V6, etc. as
Oil Pump Technology
Oil pressure is something every engine builder worries about. Low oil pressure or a loss of pressure can cause expensive warranty problems and catastrophic engine failures, neither of which is good for your business. Though the “bigger is better” mentality persists, most engines only need about 10 psi of oil pressure for every 1,000 rpm
Quaker State Challenges Motor Oil Competitors to End the “Wear Wars”
Quaker State is calling for an end of today’s “Wear Wars” by challenging its motor oil competitors to a head-to-head motor oil comparison. Quaker State has issued a challenge to Mobil1, Valvoline and Castrol to prove that that no leading full synthetic SAE 5W-30 motor oil provides better wear protection than Quaker State Q HorsePower
Racing Oil and Additves
Engine oil has sometimes been compared to a cake mix. The base oil is like the flour and the additives are the spices. How much is used of each varies by the type of cake and its intended use. Birthday cakes don’t really work for weddings. Engine builders have also been compared to gourmet chefs,
Putting the Pressure On High Power Cleaning Systems
Despite these automated times in which we live today, many shops still use manual cleaning systems to hand-clean each engine component piece by piece. This may seem slow and tedious to some, but for others it’s necessary quality control in order to remove all of the hidden particles that can cause damage to an engine
Oil Pumps
It’s 6,000 rpm – do you know what your oil pressure is? That’s a question every engine builder should know the answer to if they’re building an engine that’s going to survive. Maintaining adequate oil pressure and volume is absolutely essential for engine durability. The problem is the output of many stock oil pumps, particularly
Today’s Oil Not the Same
A recent camshaft company Technical Bulletin said it best: “Today’s engine oil is just not the same as it used to be, thanks to the ever tightening environmental regulations.” The EPA, car manufacturers, and the American Petroleum Institute (API) have done a great job reducing emissions and extending the life of emissions control equipment. However,
Pumped Up For Peformance Oiling Systems
Most OE engines use a wet sump system, which can be modified for performance applications to improve oil control and increase horsepower. A dry sump system, on the other hand, has been specifically designed for performance applications and is mainly used at the higher levels of racing where oil control is critical for producing maximum
Racing Oils Can Offer Extra Power & Protection For Your Performance Engine
Building high performance engines doesn’t come cheap. The components you use cost more, the time you take to build each motor is longer, and paying attention to detail is the name of the game. High performance engines have a very small margin for error when it comes to tolerances and extreme loads, therefore the demand
Where Should The Cam Bearing Oil Hole Be Located On A 3400 Series Cat Diesel?
A: The AERA Technical Committee offers the following information regarding cam bearing oil hole location for 3400 series Caterpillar diesel engines and installation of all cam bearings for these engines. This bulletin should be used, and service manuals published before 1985 should not be used. The correct location for the oil hole in the camshaft bearing
Turbocharged Toyota 2JZ Engine
When this turbocharged Toyota 2JZ engine got on the dyno at Victory Precision Machine, it lost oil pressure. The problem turned out to be a spun bearing and a trashed crank. Frank Mangano got to work rebuilding this engine for a 1997 Supra street application. Find out how the build turned out!
