Wiseco Diesel Pistons
Wiseco, a high-performance piston maker established in 1941, is launching a new range of diesel pistons for Dodge Cummins, GM Duramax and Ford Power Stroke engines.
The Demands on Diesel Pistons and Sleeves
The pistons are some of the hardest working components inside a diesel engine. Diesel engines are high compression, high heat engines that demand a lot from their pistons. Compression ratios are typically in the 16:1 to 20:1 range, which improves thermal efficiency and fuel economy, but also creates more pressure. Cylinder pressures in many production
Assembling the Pieces of Our 392 Magnum Project
Customer sales reps (CSR) who work for your local W.D., or any parts person for that matter, are expected to not only take orders, but are often times called upon to choose the parts a shop will use for a build or repairs. Reps may be asked to help diagnose a problem or failure without
MaxJet Provides Repeatable Carburetor Tuning
When it comes down to tuning at the track, carburetor jetting is one of the key components of a successful run. A mixture that’s too rich will have a severe effect on performance, and a lean condition could severely affect the long-term reliability of pistons, valves and other internal engine components. carbura The MaxJet Precision
Matching Pistons And Rings
Whether you are rebuilding a high-mileage engine or building a fresh engine from scratch, matching the pistons and rings to each other and the application is essential for a successful outcome. Rings are a wear component that are usually replaced during a rebuild. The pistons may be reused if they are not damaged, cracked or
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
Dry Run Friction Marks on Pistons Due To Fuel Flooding
Typical Damage Appearance Scoring is typically on one side of the piston (see piston on right in photo), and good skirt on other side (see piston on left in photo). An originally good skirt bearing panel has narrow, clearly limited longitudinal friction marks superimposed. The ring zone is usually undamaged. Assessment Unburned fuel which has
Common Rail Injection: Understanding its Importance to Today

Engine Building Legend Bill ‘Grumpy’ Jenkins Dies at 81
Jenkins attended Cornell University where he studied mechanical engineering, and he used his training and skills to build engines. He was inducted into the International Motorsports Hall of Fame in 2008 for his engine building expertise in the National Hot Rod Association (NHRA) Pro Stock division. His innovations included drag racing’s first kickout oil pans,
Quarter Mile Foundation To Raffle Mondello ‘Vintage Rat’ Engine for PROJECT 1320
“Mary and I discussed the Project 1320 Raffle Engine and with Joe’s crew at the Mondello Technical Center,” said Hrudka. “Everyone at the Technical Center is fully committed to completing the engine well in advance of the drawing. Mary told me, ‘Joe would want this engine finished. It will be a wonderful tribute and a
Uncovering the Causes of Burned or Scuffed Pistons
Question: My engine burned a piston. What does that mean and why did it happen? Answer:It means the piston failed due to excessive heat in the combustionchamber. A burned piston will typically have a melted appearance, or ahole burned completely through the top of the piston. Aluminum can onlywithstand so much heat, and when it
Combustion Chamber Mold Making Process For Custom Pistons
The following molds are examples of chamber molds NOT accepted by JE Pistons. Different resin based materials are available, but be careful as they may readily bond with metal surfaces and can be difficult to separate once cured. There are two common
Race Engine Pistons and Rings
Cubic inches is the name of the game today. The performance piston market is being driven by bigger bore blocks and stroker crankshafts. A few years ago, a 540 cubic inch motor was a monster motor. Nowadays, some professional drag racers are running engines as large as 850 cubic inches, and 600-plus cubic inch big
Diesel Pistons
The diesel engine market has been rapidly changing in recent years. Higher fuel prices and changes in emission regulations have brought about a whole new generation of clean diesel engines in both the light and heavy-duty truck markets. According to the Diesel Technology Forum (www.dieselforum.org), particulate emissions from new on-highway diesel engines have been reduced
Engine Builders: Pistons and Rings – Hypereutectic, Valve, Installation
Though pistons can often be salvaged when remanufacturing an engine, sometimes they have to be replaced. The original pistons may have worn or damaged ring grooves, wrist pins or skirts, or they may have cracks. New pistons may also be necessary if the cylinders have too much taper wear and the block has to be
Line Boring Equipment: A Boring Subject?
But as the British philosopher Bertrand Russell noted, "Change is one thing; progress is another." While some might say the basic techniques for line boring main and cam bearing bores in engine blocks hasn’t changed much in 30 years others say that isn’t such a bad thing. A horizontal boring bar with cutters mounted on
Pistons and Pins: What’s New
Asking piston manufacturers “what’s new” reveals a number of trends that are reshaping the piston business today. One is that there’s no longer a time lag of three or four years for aftermarket piston suppliers to tool up for the latest piston applications. Production engine remanufacturers (PERs) and custom engine rebuilders (CERs) are asking for
Performance Pistons
Piston manufacturers are introducing new performance pistons for all of these applications as well as refining existing piston designs to reduce weight, and improve strength, durability and ring sealing. Piston design and manufacturing used to be a relatively low-tech process. Now, with the aid of finite element analysis and other computer modeling techniques, many aftermarket
In Search Of New Markets, Mike Jeffries
Looking for new markets is one of the toughest things we do, so every time the phone rings we listen for an opportunity. Most of what we find is suspect, but over the past 12 months we have rebuilt a number of compact diesels and sold a number of rebuild kits. As a result we
Pro Circuit KX450F and RM-Z450 High-Compression Piston Kits
Pro Circuit’s newest products are High-Compression Piston Kits for the 2016-2018 KX450F and 2018 RM-Z450. Manufactured by JE Pistons to PC’s exact specifications, Pro Circuit pistons are forged from high-quality aerospace aluminum alloy.
