Diesels Take Over the Pacific Northwest

This past weekend XDP ventured north of the border for BD’s Dealer Day, Dyno Day and BD Truckin’ Nationals event. Our staff toured BD’s wonderful new facility and learned more about their products and how they are manufactured. Their new facility is massive and all of their equipment is state-of-the-art. Saturday was BD’s dyno event, which was an absolute blast! It seemed like every truck was north of the 500 horsepower mark with some crossing into the 1000 horsepower range. Everyone at the event had a great time and watching some of these trucks lose traction on the dyno was absolutely incredible. Several trucks had so much power that they had to put weight in the bed so they could maintain traction on the dyno rollers.

The weekend culminated at Mission Raceway Park in Mission, BC Canada where the NHRDA hosted some extremely competitive compression-ignition drag racing. Mission is an incredible racetrack; it is surrounded by mountains on every side and is at sea level so all of these trucks were breathing in cool, dense air. Aside from a mild morning shower, the weather was beautiful and the fastest diesels in North America ran until the late afternoon.

XDP had a great time in the Pacific Northwest. It’s clear that the diesel bug has definitely bitten Canada just as hard as it has in the states and it was a pleasure seeing hardcore racers, daily drivers and weekend warriors all doing what these trucks do best: making serious horsepower.

World Debut of the New XDP Diesel Monster Truck

This past weekend at the 4Wheel Jamboree in Springfield, MO, XDP’s brand new diesel powered monster truck co-sponsored MBRP Exhaust and BD-Power made its hotly anticipated debut. The 5.9L Cummins powered 2010 Super Duty was the talk of the event with people scrambling for photographs with its driver, Dave Radzierez, and the only diesel powered monster truck in the world today. After an initial, extremely competitive race with one of the legendary Bigfoot trucks, steering issues sidelined the truck from racing for the weekend. Dave took the truck back out for the evening’s freestyle event and put on an exciting smoke show that culminated in him jumping the truck over a mud pit from the day’s earlier bogging event. Several things were immediately apparent about the truck: Diesel power can get one of these 5 ton behemoths moving with just as much urgency as an alcohol fueled truck, Dave Radzierez can wheel, and this year’s 4wheel Jamboree has an exciting new entrant that’s going to put all of the established players in the series on notice. 

Diesel Particulate Filter: Get to Know What’s Under Your Truck

All diesels from late-2007 are required to have an emissions device on them called a Diesel Particulate Filter. These filters dramatically reduce soot (particulate matter) emissions and have played a huge role in protecting diesel passenger vehicles from increasingly stringent emissions standards. Ford, GM and Dodge all equipped their trucks with these devices and in 2011 Ford and GM also equipped theirs with SCR (Selective Catalyst Reduction) as well as Dodge on their Cab and Chassis trucks, reducing emissions further and increasing horsepower by allowing the truck to be more aggressively fueled from the factory while still meeting emissions standards.

The DPF is similar in design to a catalytic converter and is placed after the catalytic converter in the vehicle’s exhaust. Its sole purpose is to block soot and reduce the emissions that make it out of the tailpipe. When the DPF filter becomes clogged, it needs to be heated to clean itself out. To accomplish this, the engine injects fuel in on the exhaust stroke so that it heats up and travels to the particulate filter, burning up any matter that is clogging the filter and allowing the truck to run correctly. The downside to this is that it takes a reasonably large quantity of fuel to clean out the DPF, or “Regenerate.”

The DPF works in conjunction with the EGR (exhaust gas recirculation) system which routes exhaust gas back into the engine to be burned again, which cleans up emissions by further breaking down the chemicals in the exhaust. The downside to the EGR setup is that it can reduce engine output because of the hot air being sent back into the engine and it dirties the inside of the engine over time. On the 6.0L Ford trucks, the EGR system was the cause of much more serious engine problems involving heightened cylinder pressures and blown head gaskets.

SCR, which is the injection of diesel exhaust fluid (DEF) into the exhaust to reduce NOx emissions, is another process that manufacturers are using to cut down on the emissions of these trucks as well as restoring lost horsepower. SCR allows the engine to fuel more aggressively while still meeting emissions standards because the urea in the DEF chemically alters the exhaust gas before it reaches the catalytic converter and the DPF, reducing the risk of damage to the DPF from over-fueling and cutting down on the frequency of the regen cycle. SCR’s biggest limitation is the requirement of fluid additions between oil changes; the fluid is not inexpensive and is not widely available yet.

That is a basic synopsis of how these devices function, but the most important thing to know is exactly how these affect your truck and the way it runs. For starters, a truck equipped with a DPF from the factory is likely going to return lower fuel economy than an older diesel that is not equipped with a particulate filter. The reason for this is simply that the regeneration process uses (potentially) gallons of fuel and that fuel is not being used to make horsepower or accomplish any work. Trucks that haul loads or are driven around town frequently will have to regen less often because the filter is more efficient under higher loads. Conversely, trucks that spend lengthy periods of time at idle or on the highway without a load will have to regen more frequently and in turn see reduce fuel economy.

Removing the particulate filter is a violation of Federal emissions regulations and is designed specifically for race and off-road use only. XDP carries all of the DPF, EGR, and catalytic converter delete setups for Dodge, Ford and GM as well as the required tuning for these vehicles.Trucks with a DPF equipped will benefit from the use of a quality fuel additive like XDP Diesel Power Plus (http://www.xtremediesel.com/xdpdieselpowerplusfueladditive.aspx). This additive boosts the cetane rating of the fuel by 5% and cleans out the fuel system so the engine produces lower emissions, which in turn means the DPF does not clog up as quickly or as frequently. These trucks are also more sensitive to maintenance, so making sure that the truck has fresh fluid and quality fuel in it will help improve the performance of the vehicle. Finally, doing a cold air intake, programmer and filter-back exhaust setup will help improve fuel economy and performance as well as lowering exhaust gas temperatures.

Particulate filter technology is evolving quickly and is going to be equipped on every diesel passenger vehicle designed and built in the foreseeable future. As the technology improves, horsepower and fuel economy will improve along with it. For now, the tips we outlined above will help you to improve the performance of your truck while abiding by federal emissions regulations, and for those looking for big horsepower race trucks, we have the delete pipes you need for those as well!
