Diesel Jam Injector
Posted January 3, 2007

Jam and Inject
Diesel Dynamics "Jammer" injectors give Cummins engines 50 to 175 more horsepower. These Jammer units are for '98.5 to '02 5.9L Cummins ISB engines in Dodge Ram trucks and RV coaches. The proprietary process used to create these injectors intricately machines eight orifices into the tips. Compared with the stock seven-orifice injectors, Jammers feature better atomization, faster fuel flow, and an enhanced spray angle. The increased number of orifices also enables the injectors to deliver more fuel, while still maintaining proper fuel pressure. The result is more power and improved combustion-chamber cleanliness. The Diesel Dynamics machining process also matches flow rate to within about 1 percent among injectors, further enhancing engine performance and smooth operation. The stock injectors can vary as much as 11 percent per set. Jammer Injectors are available in five configurations. Stage 1 increases horsepower by 65-plus in Cummins-powered pickups. Stage 2 adds as much as 85 horsepower, and Stage 3 increases horsepower by 100. For competition/off-road applications, Diesel Dynamics offers two pure-performance stages. Combined with other upgrades, such as aftermarket engine-control modules, a set of Stage 4 Jammer injectors will add as much as 150 horsepower, and the full-on Stage 5 kit can increase horsepower by 175. Across the board, Jammer injectors can also improve fuel economy by as much as 1-1/2 mpg, depending on individual driving style. The injectors can be installed by the average home mechanic. Using ordinary handtools, the competent do-it-yourselfer should be able to install a set in two hours or less. For more information, contact: Diesel Dynamics, Dept. OR, 6280 S.

Miller Electric Mfg. Co.'s new Big Window Elite Series of auto-darkening helmets offers exceptional performance in all welding applications and is specifically designed to satisfy the most demanding industrial requirements. Exclusive features include four independent arc sensors and a 30 percent larger lens window than Miller's standard helmets. The independent sensors improve out-of-position welding, while the larger window provides maximum viewing capability and retains a 4-ounce weight edge over competitors. The Big Window Elite features Miller's new replaceable battery/solar assist Performance Series lens technology. As incorporated in the Big Window Elite, this permits 3,000 hours of operating time before its two batteries need replacing. In addition, Performance Series technology offers excellent low-amperage TIG response and excellent DC-TIG inverter arc response, down to 5 amps or less. It also protects operators working in high-duty cycle applications. For comfort, Miller borrowed operating-room technology used by doctors and incorporated a form-fitting foam-rubber comfort cushion that attaches to the back of the head gear. The Big Window Elite helmet is available in black, two flame patterns, and a patriotic stars-and-stripes design. The Miller helmets are covered by an 18-month warranty.
